Uncropped zvichana derevna breed has been left behind. I would like to partake of the information on the bottom of the material, for the parameters of the program. The buyer will be looking at the village of the following views:

Stabilized

The tree has been stabilized to be ready to go from the drops of precious woods. Vona is not afraid of temperature changes, vologostika, stiyka to diyznyh acids and roschinnikiv, ultraviolet, salt water. Sob to reach the power of the tree, soak it with monomers and acrylic resins, and open them with pore.

After completing the taku obrobka, the tree of the nabuva of the advancing powers:

• do not deform and do not shake;
• showcase heating up to 100 ° С;
• low hardness and taste;
• kindly polish;
• she's scrubbed with herds.

In the main stabilized tree vikoristovuyut for the preparation of handles of knives and other exclusive virobes. The yak bars are let out. The price of a bar with a size of 40x30x125 mm should be close to 900 rubles.

Modified

Modified wood is obsessed by the method of percolation of wood with water cut to carbamide, phenol-formaldehyde or polyester resins. For this kind of obrobka, the wood is not afraid of aggressive and abrasive middlings, shock waves. Stop accumulating static electricity. Decrease in hygroscopicity, decrease in swelling, increase in performance,

There will be booths in the modified tree. The stench is viglyadayut douzhe vishukano і does not require obroboka. For shrinkage, no shrinkage occurs. This is a very promising material for frame construction. Yogo admission rate will be 18 - 22 thousand rubles per sq. M.

Kleєna

Kleєna derevina vypuskatsya three types:

• saruvata;
• masivna;
• combined.

Sharuvat with products to shrink from veneer, otmuyuchi yak glued plywood. Glue boards, bars, plates are introduced to the massive tree. It is combined to let go of the view of the carpentry slabs, to get the grip on the veneer of the massive wood.

There will be booths and furniture shrinking from the glued products. The price per cube becomes 22 yew. up to 25 yew. rubles

Impregnated

Impregnated wood should be cleaned with a path of seeping wood in a special warehouse. Until now, there are naphtha mixes of ridini, creosote, and also half of mish'yaku and chrome.

Leakage should be carried out in chambers where it is hermetically sealed, and the boards are placed in them. After the chambers are secured, the warehouse will be served.

Impregnated products to serve for five times more for the extraordinary and non-permanent production of varnish-based materials.

Vona is ideal for constructions that can be used with water or soil. It is necessary to strip the berths, to shake off the stoves for fences, beds and kvitnikiv.

The percentage of the impregnated tree is from 14 to 16 yew. rubles per cubic meter meter, import - from Finland kostu from 35 thousand rubles. for 1 cubic meter

Heat-cured (thermally modified)

Heat treatment will shrink the power of the tree and it is a single alternative to chemical processing. The technology of polyaga in the nursery tree with water vapor at temperatures of 220 - 240? The changes in the structures of the material are taken on the molecular basis. Trivia processing cycle 12 years.

Thermally modified products have three main powers:

• style to biological differences;
• vologovidshtovhuvannya;
• stability of the size.

From thermo-wood to rocking furniture, parquet, vikoristovuyu for upholstery of budinks. Stagnate during robotic robots in children due to the advanced vology. Even more popular is the production of window frames. Price per square meter from one to five yew. hryvnia fallow in the form of doughs, the variety of that breed.

Moraine

Morena is a village from the flooded forest. Vaughn vikoristovutsya at the buisness, at the furniture virobnistvі. The village is even more expensive than it was by the water, it’s old. The creation of such a natural processing of the won is filled with a whole series of unique powers that have become even more powerful. One cube of sea birch kostє 1600 UAH Modrina kostu at 15,000 rubles per cubic meter

Consistency: the method of preparing the pressed modified wood for leaking out of the village blanks by means of water cut carbamide should go under vacuum. Presuvannya to spend at two stages of skidding a vice between them, moreover, at the first stage of pressing the material is 5-25 minutes, at the second stage it is 45-95 minutes. The step of pressing the heat treatment should be carried out at temperatures of 150-180 ° C with a stretch of 60-150 min. Leakage of workpieces should be carried out in the presence of phosphoric acid in the presence of carbamide and phosphoric acid from 2.5: 1 to 30: 1. With a whole amount of carbamide vitrate, make 5-15% of the mass of absolutely dry wood workpieces. 2 c.p. f-li, 2 tab.

Winning is carried out to the woodworking industry and can be bought from the woodworking parquet, furniture parts, parts for the processing of wall and wall panels. In the form of ways of removing the pressed modified wood by means of a path of seeping the wood with carbamide, drying and preserving (1). In a shortage of a conventional method є the triviality of the technological process. The closest analogue of a technical solution, it is claimed, is a method of preparing pressed modified wood, especially for parquet, by way of seeping village workpieces with a water cut of carbamide, pressing at a pressure of 0.5-3 MPa and a temperature of 160-180 times. When the leakage occurs, the carbamide with a concentration of not more than 30% should be 1-9 dib, and the temperature of the leaked tree should be left before pressing at a temperature of 110-120 ° C. In a short-lived way, those who, during thermal processing, see a plasticizer (Н 2 Pro) and at the onset of the technological stage - pressurized at temperatures of 160-190, the decrease in the amount of the plasticizer has a negative effect on the efficiency. Besides, this kind of method is also a trivial technological process. The new technical result of the claimed method is to intensify the process for one hour advancing the quality of the pressed wood. A new technical result is attainable for the preparation of the fact that in the way of making pressed modified wood, it is important for parquet, by way of seeping village workpieces with a water cut of carbamide, pressing at a vice of 0.5-3.0 MPa at a temperature of 160-180 about the size of the term, Leakage is done before vacuum, pressing is carried out at two stages of pressing between them, and at the first stage of pressing the material is 5-25 min, at the II stage it should be vitrified 45-95 min, and the thermal processing should be carried out for 150-180 min. 60-150 min. Leakage of wood blanks with carbamide can also be carried out in the presence of phosphoric acid at a ratio of 2.5: 1 to 30: 1. For a whole lot of carbamide, take 5-15% of the weight of absolutely dry wood blanks from a batch, and phosphoric acid - from a batch of 0.5-2.0% of a weight of absolutely dry wood blanks. Seemingly, it is possible to increase the intensity of the leaking out of the wood in a vacuum (the journal "Paperova Promislovist", No. 6, 1970). However, in the proprietary method, the leakage of carbamide for the method "vacuum - atmospheric vice - vacuum" in the process of forgiving presupposition nayratsіonalnіshe. A positive effect in the case of a two-stage crimping tree of dressings with the ability to crimp blanks with a high-pitched lead and a clearing in the offensive. The water at the first stage is pretreated with a quick heating, prepared with a plasticizer of the village speech and will provide light hydrolysis of the ligno-carbohydrate complex. Carbamide due to plasticization. In general, it is necessary to produce up to the development of high molecular components at the temperature of pressing and pressing the tree in the grip of pressing. Skidding off the grip is necessary for the great visualization of the main part of the water from the viglyad bet. Tim will speed up an hour by himself, depending on the dry land at the pressed mill. The physical mill of the size of the components does not change. With a grip on the other stage to the maximum value, you can reach the steps of the gap, so you can work it out. Then we can carry out the vice-versa. At the first stage, chemical reactions of the transformation of the main components of the wood and the interaction of carbamide and products of the thermal transformation. A plasticizing effect in the world of drying and re-engineering of knowledge, and macromolecular reactions of lacing stabilize the pressed wood. It is safe to use the village to bury the chemical reactions on the heat treatment of the chamber with a stream of hot food. The transfer of a separate thermal inflow into the rationalization of an expensive presuvial possession of such a short view of surplus water for the prevention of increased condensation pressures during thermal treatment (in special chambers). Proponations of wines are illustrated with such butts. PRI me R 1. The way to prepare the pressed modified Osika tree, come to an offensive rank. Dry and dry workpieces with a diameter of 22x28x150 (cob size of workpieces 470 kg / m 3) close the autoclave at the vertical position, set a vacuum of 0.095 MPa and turn the workpieces 10 min. Then feed 10% carbamide (15% vitrate of absolutely dry workpieces) into the autoclave, install an atmospheric vice and vitrify the workpiece 10 min, then pour it out. Zagalna triviality leaked 30 min. Then, at the same time, we are able to provide two-way pressure for the offensive mode: I step of the pressure. Drive a vise up to 2.5 MPa (30 sec.), Parking 5 minutes and a vise; II stage. Drive a vise up to 2.5 MPa (with a stretch of 10 s), parking 45 min, then step down a vise to atmospheric; Introduce the heat from the frame and heat the casing in the box with the temperature, which is regulated, at a temperature of 170 about C for a stretch of 120 minutes.

The village (lignoston) is the material of obsession with the path of hot pressing of the bars of the whole tree, which is squeezed out in the surroundings in front of the middle leaked by the deeds of chemistry. Forwardly, it was logged in 1915 from the beech tree by the way of all-purpose slashing of a bar in an autoclave in molten asphalt. It means that the material of the type of logoston bulo is removed from the beech tree for more than 200 years (the tree for making the handles of folded knives was pressed in a heated mill between two plates). A beech tree і in daniy hour є sirovinoy for virobnitting lignoston beyond the cordon.

The SRSR V. G. Matvev (TsNILKhI) has broken down the original method of eliminating lignoston from the birch tree.

Lignoston vigotovlyayut at the viglyadі square bars or rectangular ones (up to 8-10 cm) up to 1 m; for weaving dummies, the bars may be 4 cm X 5 cm X 40 cm in size. In the process of rejection, two can be reached; First, go to the path of the mechanic defilement of the tree, and to the other, the singing world, behind the additional thermal treatment.

The technological process of preparing solid wood is stored in the following operations: I) shaping the logs into bars with a permit for shrinking and shaping; 2) drying the bars to a content of 10-12%; 3) p'zothermic processing; 4) cooling and residual processing of the bars in the signstone.

P'zothermic processing must be stored in the advanced stages:

1. crushing of the bars at the cold mill;
2. alternate progr_v slightly gagged bars;
3. presuvannya;
4. thermal processing of pressed bars;
5. chilled.

All operations are carried out on the same tedious hydraulic press, provided with the stationary preforms, filled with a pair and cold water, or else it will be done, and on the press, it is necessary to carry out a special reduction. The bars are put into individual metal molds, when the heat treatment is finished in a squeezed-in mill, they go into the cold water, de cooled down with a cold water jet.

Our industry has adopted a stop method, as it is not a forced press. The production of lignoston from the (distribution) method is built up from the onset of operations. Hanging and shaving off the bar can be placed in a mold, with a massive metal box with a punch. If you appear in the village of trishchin when it is heated, the tree will go down in front (by 10-12% of the height of the bar) with a way of pressing down with a small grip; 25-30 kg / cm 2. To increase the plasticity of wood with residual pressed bars in the molds, they are heated for about 1 year in ovens at t = 160-180 ° (for birch wood, the temperature is optimal in the middle of the bar at 10 -12% of air quality). In order to carry out the pre-treatment of a given step of the reduction; for a birch tree at 10-12% of the volumetric value, the coefficient of the maximum reduction for the road is 0.55. The pressed bars in squeezed molds when reaching the end of the clamping grip can suddenly be warmed up at t = 160-180 ° for 1 year or 30 minutes. (For a birch tree in the middle of the bar, when the fault is reached, the optimal t = 125-130 ° is reached). The second program can be used to increase the strength of the pressed villages against the diy vology. When the program is finished, the bars are squeezed in the molds, the bars are cooled in the cold ones with a cold water jet to t = 30 ° in the middle of the bar with a stretch of 30 minutes. at t turns 1-3 °, it is removed from the molds.

P. N. Khukhryansky of other disintegration, The easiest way to preserve from the front ratios. Virіzanі from the logs from the logs of the wood 30-40% steam until the tree does not warm up throughout the whole period of the bar up to a temperature of 90-95 °, for which the bars are pressed to a predetermined level of pressing for one day at 70 ° ... The pressed bars are cooled at a working temperature of 10-20 °, they are removed from the molds and dried without scraping near the drying chamber to a wood content of 10-12%. Hanging bars are vitrified in a working room for 5 days.

Ob'mna va and the lignoston is significant, not natural (vychіdnoy) tree, and lie down at the step of the gap. Behind the cordon, lignoston is divided into three classes:

1. lightweight, with a large carriage 105-115;
2. middle-1, 18-1, 25;
3. normal-1.3-1.46 g / cm 3.

With a hundred shortcomings of lignoston, especially rejected in a different way, it’s inappropriately strong against the flow of water, before the flowing tree turns into a cobbed mill in a small world, consuming power with all its power. In order to ensure greater stability, the tree should be improved with speeches in front of it, so that it will reduce the health of the patient (with glucose, piece resins, salts of important metals).

Physical and mechanical viprobuvannya lignoston viroblyayutsya for the methodology established for viprobuvan natural wood (OST NKL 250); ob'єmna vaga viznachaatsya behind the aid of the volumenometer on the zrazkah - the shape of a cube with a side of 2 cm; volatility, shrinkage, bulking up and cladding - for OST NKL 250; Viprobation on the grip of the fiber bridle is carried out on a cube shape with a side of 2 cm with a pressure of 7000 kg ± 15% for a chill for the entire length; for viprobuvannya on static і shock vigin, such a vigilance will be stagnant, but for natural wood, with the same viprobuvanny scheme (OST NKL 250), but the ability to apply with static viginous growth is ± 20% for 1300 kg; viprobuvannya for skolyuvannya vdovzh fibers - according to OST NKL 250; for viprobuvanny for stretching of fibers, in case of consumption, you can use a method for stretching, recommendations for viprobuvan delta-tree divas.

The traditional way of determining the hardness of the lignoston is not suitable, fragments when the punch is pressed in to reach the value of the punch at a time; In addition, it is a very hard method, when it’s hard, start by pushing on the viprobuvan surface with a steel sack with a diameter of 10 mm (150 kg vantage) with a vantage vantage for 15 seconds.

The characteristic of hardness in the whole range is the value that can be calculated according to the formula

de: R - vantage in kg; F - the area of ​​the bead mm 2, tobto. the projection of the hole onto the square of the zrazka, rivna pD ^ 2/4, de a is the diameter of the bead, the offset is arithmetically mean from two vimir (height and across the fibers at different values ​​of the hardness of the bit surface), readout is 0, accurate to 01 mm.

The physical and mechanical power of the lignoston lies in the way of its rejection and in front of the step of the ravine of the tree, which is characterized by a voluminous wagon, which can be illustrated by the data of the TsIILHI, as indicated in the table. 83.

Table 83

Physical and mechanical power to lignoston

The characteristics of the lignoston's quality at a static action of forces at times fall without a change against natural wood, but for a shock zgini decrease by 1, 5-2 times. The price, obviously, is due to the change in the chemical warehouse of the cinnamon sheath.

Lignoston is kindly given mechanical processing - sawing, drilling, milling and cutting. ale vimagaє tools from a high-grade steel, admitting gluing of casein glue, ale of z'єdnati yogo tsvyakami mayzhe is uncomfortable. Coating it with varnish for a blistering bite, so that the chipped surface of the lignoston looks smooth, but it is less important in weaving chapters.

In the SRCP, the logoston is stuck as the head rank for the production of weaving chaplains; order z cim winners to be used for inserts in bearings in hot rolling mills, de winn replaces bronze and textolite, for extra saw frames (replaces bakout) and in.

A tree is a whole natural polydimensional composite material, which, when mechanically and chemically infused, changes its power. Knowing the laws of change to the material, it is possible to create it in a straightforward way, to produce the quality, the necessary support. Tse and be called the process of modifying the tree... Wines are necessary when making chipboard, MDF, OSB, WPC and other village materials, wood, change from polymeric materials to be judged by eliminating one-sided material of standard sizes.

The technology of modifying the tree was promoted to change the power of the tree in the massif, so that the entire surface of the material could be cluttered without being drawn into it. It’s not possible to reach those, that the molecules of the modifier, that is, the speech, that the change of the power of the tree, beyond the size of the molecule of the village speech, and less of the size of the small spaces in the new one. In this way, the modifier penetrates the whole depth of the virob, and then, due to the flowing temperature, it reacts with the natural chemicals, which are found in the countryside. In such a rank, technology allows, not to trim the wood, not to waste the expensive polymeric materials, and to achieve the same effect that was used when using MDF, for example, in a cheaper way. At the same time, the mass of the tree is protected from the use of positive power, the texture is more visible, it is possible to change the color (the lamina is not known).

Already, the modifier is guilty of the broken mill to penetrate into the tree structure of the tree, but it is chemically active for the components that make the village the word, and, reacting with these components, is directed to change the physical power of the tree. Naybilsh as an adjunct for the whole speech є carbamide, Even those who have previously had MDF or OSB are the most expensive ones - carbamides. Carbamide roschinny near the water, including, in that case, to take revenge at the knotted camp in the village, but it means, so, let the tree seep through the water with a water rash carbamide, mi, as it’s not paradoxical to “go dewy”, partly vologians hydrophilic carbamide. Carbamide or sechovina actively react with such wood components as lignin, hemicellulosis, extractive speech. And oskіlki polycondensation reaction to be seen in the macromolecules of the village speech, the mass of the tree is filled with new cinnamon yarns, so that you can become a virobnik, who are positively old. Razchin carbamidu is not shkidlivy, chemically neutral, more - grade A for GOST 6691-77 yak feed additive for thinness.

The wood is modified with carbamide and is certified (GOST 24329-80) and is stored under the trade mark "Destam" or "Lignoferum" from the electronic bearing deposits.

Through thermal destruction, the physical and mechanical power of the thermomodified tree is reduced.

Technological process of production of mechano-chemically modified trees of the field in the leaked willow tree, be it a breed or be it a kind of a modifier's rosette. Leakage can be carried out by the method of "hot-cold baths" - diffusion or in an autoclave - primus. It is possible to carry out drying, if necessary - with pre-treatment, heat treatment, as well as the new power of the tree. Slide to mean that economically vikoristovuvati little breed, some of the exploited characteristics of the change to rewrite the characteristics of expensive breeds (div. Table).

The tree is covered with such a rank of vikhidnaya for an hour, it is chemically impaired to see how the modifier reacts with the woody river: by 5-31% for conifers, by 12-35% for the foliage. For the consumption of a large loss, it will become hotter than the drying of the hanging tree with a loss of 50-70%.

Stagnant growing additives to a modifier, from any breed of a wild tree, it is possible to adapt a modified village (MD) with the power of power, high solidity and old age who do not grow up to the poor ... The wood has also been mechanically modified to be transformed into thermoplastic material, so that it can be pressed, easily bent, rolled with thermal rolling, so that the new technological capabilities of the MD coffin can be seen. The form, which is supposed to be MD, is protected by heat cork.

If it is necessary to trim only a log, a bar, or a board with modified wood, since it will be used up to the traditional woodworking, the process can be carried out the last time in soothing baths or autoclaves, drying - in the heat chamber For the summing up of these processes, a special installation for modifying wood (UMD) was broken up and tested.

Fig. 1 Pre-industrial design of the installation for the modification of wood from a closed volume of 0.2 cubic meters.

The installation permits the leaking of the modifier to be carried out with a grip, accelerating the drying of the leaked tree in case of a wrinkling grip and temperature and residual thermal processing in one cycle. Installation allows for a special profile of MD or a special profile on the virob behind the additional thermocompression insert, which is included before the set of PMD.

So a deck with a diameter of 150 mm before a chin of 2.5 m for a freshly cut mill with a volume of 85%, a thickness of 450 kg / cubic meter.

• volatility 8%;
• gustina 630kg / cubic meter;
• fire resistance is increased by 50%, and when special additives are used up to a modifiable size, the deck does not change;
• the content of the product has been adjusted by 30% (more - when special additives are added to the modifier);
• MD injected with bioshkidnikiv (flowers, fungi, bugs too) is not strong;
• vipadnі knots embedded and fused;
• on the well in the process of drying, there can be a vipresovano groove and a comb for joining when the cut is folded (viprobuvano - 15mm glybin);
• The texture of the wood is yaskravo swirled, the color can change from golden to dark brown all over the world.

Mechanically modified wood is chipped on gray wood-working verstats with a high degree of hardness before an hour is spent on tools. The factories of the MD deformability adjustment before the heat treatment, it will be frozen like a crimp in the presses with plates, it will heat up, it will not be hot and rolling.

Zrazki wood, processed in the UMD: logs of pine, birch, yalini, log of oak right-handed logs with vipresovanny grooves for folding

Presuvance allows you to trim on the surface of the shield from the MD large images (depletion) up to 10 mm thick, as well as flat images with the effect of size (holography). Before the speech, for a hot press, there is no need for a press-form operation, so as the surface of the virob is set to polish the press-form. Lacking is not required either, since it is a warehouse, which can be modified, installed on the surface of the virob, I will add water when pressed.

Razmіri vyrobu, how to be overwhelmed, according to the area of ​​size, they begin to fit the plates of press possession, moreover, the part of the possession itself can also be stored in all kinds of sizes. To be unique when preparing virobes of a large area from mechanically modified trees, a method of thermocompressive molding is used.

Ways to succeed in the offensive rank: wood blank at the viewer of the joinery and furniture board assembled from the slats is placed at the lower part of the special press form (SPF), the contours of which form the contour of the blank. Above, there is a relief stamp, which forms a decorative image on the surface of the workpiece. Between the upper and lower parts of the SPF there is a storage elastic molding insert, which is thermally expandable, which, when heated, will provide the necessary vice up to 30 MPa. The step of deforming the deposit is deposited as a form of deposit. Razmіri vyrobu, so be contented, but begin without the size of the SPF and the folded insert, so that it allows you to open the wall or the part of the door, be it a size.

The blanks of the joinery and furniture boards are made from around the MD slats, which can be either of the same width or of the same type. The technical result can be reached by the time, that at the outward rails from the modified tree, they can be calibrated, open with the singing crochet, set up the cross channels, connect with the advancing rails of the shield, and on the lateral surfaces of the forces of the armored resin with pintuvoryuvach and napovnuvach in viglyadі tirsi. Warehouse for the material of the power grid is of the same type as the modifier, and as a result of the polycondensation reaction, additional polymeric polymeric interconnections are created in the process of pressing. The power armored lattice will ensure the monolithicity of the virob during the operation and operation of the shield of great development. teksturi ta kolori. Їhnya chastkova inconsistency to be compensated for by the stems of a one-sided color background and a decorative one-piece at a hot press. Besides, there is a special way of transmitting a wide assortment of virobes in case of victorious versatile species of wood, which are not fabulous.

Technological process of clearing a tree in a thinly seeped wicker tree. For thermal processing, the virob can be changed if it is heated at 200 ° C. The most difficult process of bending is caused by hard-leafed species, as for beech and oak it is unwise to preserve the wilderness of wood for the need for great deformations. As a result, the oak is moraine (black), and the beech is dark brown. Most bend the wasp, with a lot of it swells a golden vidtinku. Dribnoseriyno, at a trial party, viprobuvano made frames for oval mirrors with a size of 1410x410mm. Procurement: a beech rail with a length of 2m, with a straight-back overretch 12x22mm, moreover, it is necessary to bend for the best size overrun. The part was a U-shaped piece, with a size overrun on the face side - 22mm, bend - 12mm. The bending was carried out without tires, since it is problematic for such a small size (12mm) to break it down, behind a template, in which case it was heat-treated to get it in a fixed mill. As a result, there will be no more (skolyuvannya), if on the last bik there will be overrun fibers (skewer). The results are in the photo.

Drying and pressing of end blanks from mechano-chemically modified wood has been tested. The pressing of end blanks from MD has its own specialties: MD should be strained in an axial straight line, so that the fibers can be increased, so it’s necessary to formulate such a vise, be prepared to use the same so as tangential and radial stress, which occurs at the end press, may be the opposite signs.

As a result of carrying out additional physical and mechanical powers of the end modified tree, it was established that it is a parameter that characterizes both the process of pretreatment and the material, it is possible to take steps of deformation of the tree. Zusilla presupposition is to lay down as a kind of wickedness of a stasis of a tree that is directly presumed. For the achievement of the same gustini MD of the younger generation, the deformation steps are meaningful to develop and lie down like a gustini tree and vologosti in the process of pretreatment. It was also established that the boundary deformability of end blanks of the MD of pine becomes 75%, and the MD of birch - 70%. However, with such great deformations, there is a loss of the stiffness of the modified tree with fibers, which can lead to the creation of chips and cracks on the face surfaces of the teeth. Otzhe, usunennya of cich chinniks, it is necessary to enclose the radial deformation of the MD, that is, it is necessary to fix the mold with the standard MD in the process of carrying out the end pressing.

In the Danish hour from the end wood, cases and barometers are made at TOV "Kut";

The transfer of products from MD will be a company, the main direct activity of such life and healthiness of living conditions, the fragments of power of the product unique. So the deck and timber are the best material for business buddies, lazen, and state-of-the-art buddies. The technology and possession for the complete set of all equipped objects with MD has been broken up: a deck and a bar for a power frame, a board for a podlog and perekrittiv, molding and a bar for door and window blocks, shields for internal decorative wake-up. At the same price of production, they will be unimportant for the price of virobes, which are traditionally made from the woods, but the power is unique. Further, the development of the market is determined by the decorative power of the MD and the technological possibilities of processing: pressing, the possibility of rolling. Price for the beginning of the number of potential customers: air blowers, furniture, designers, SUVs.

A clear message will show that the stem of the virobniches from the preparation of the modified tree does not require great vitrats and great areas. Ownership can be purchased by the repair and mechanical services of the industry. People who tell you are allowed to talk about those who are victoriously modified trees, who are trained from a cheap little porous tree of small leaves, who are allowed to expand galusies who are hungry, who are reduced vitratios who are growing up

Modified Calling the whole village from the direct change physical and chemical methods and authorities. According to GOST 23944-80 and GOST 24329 - 80, there are five main methods for modifying and different types of products.

The tree of thermomechanical modification is called the pressed wood (DP). When pre-steamed or heated, the tree grows across the grain in the area across the fibers to see a change in the macrostructure of the tree, to improve the strength and polymorphism of the knitting due to its authorities. Robots with thermomechanical modification, carried out by the Voronez Institute of Technology and Technology (NINI VGLTA) and other organizations, made it possible to promote advanced technological processes and to eliminate the disadvantage.

The village has been thoroughly trimmed, the vicoristy breeds of the leafy breed, and the hour coniferous and the hard leafy breed. Vimogi to sirovini for the preparation of DP regulated by GOST 23551 - 79. Grades, sizes and indicators of physical and mechanical powers procured a bar and board type, as well as cylinders, bushings thin. Craft capacity 800-1350 kg / m3.

The wood is pressed into a little bit of development, it’s hard and impact-resistant, it’s not natural; The tree is good to extinguish vibrations, the power to shake off abrasive particles, so grabbing it comes down to it. At the water, a tree is pressed and the deformation is tilted. However, in some cases, the development and promotion of DPs can appear in cinnamon, for example, in the narrow annexes of hydraulic machines. The wood has been pressed into place for the preparation of bushings for the support kovzanki, gears, parquetry and other tins. A modernized village can be modified, reminiscent of oliyami, metals, polymers, head rank with the help of reduced authorities as antifriction material.

With chemical-mechanical modification, the village in front (or at once) is covered with amiak, with a bit of it, and then it is lowered. The Institute of Chemistry of the Wood of the Academy of Sciences of Latvia has broken up the technology of removing lignamon - material from wood, chipped with amiak, preserving and drying. In front of the front, the cheeky processing of the wikklic is to the change of the authorities of the clientele, the tree is plasticized, and it is easy to form a new form. The wood is plastified with amiak, it is clayed with water, it is swollen and distributed. The inflow of the adjusted temperature can change the shortage. Indicators of physical and mechanical power of workpieces from lignamon guided by GOST 9629-81.

From the indiscriminate plasticized amiakom pressed wood, they make furniture details, parquet, musical instruments. The village was modified with a sečovinoy pressed vikoristovuyt for pidlog.

A tree of thermochemical modification is a material that can be rejected by leaked wood with monomers, oligomers, or resins, and other heat treatment for polymerization or polycondensation in a warehouse, which leaks out.

In some cases, the modifier is reduced to polydimensional wood components. The wood should be permeated with the most frequent phenol-formaldehyde resins, for example, at the water level of phenol alcohols, furan-type resins, polyether resins, etc. Robots with thermochemical modifications were carried out in BelTІ, the Central Scientific-Preceding Institute of Educational Structures (TsNDIBK) and other organizations.

Modification of wood with synthetic resins reduces hygroscopicity, water clay and water penetration, changes in swelling, changes in meatiness, hardness and hardness, but often decreases impact in viscosity. The formulation of resins has been developed, as it is possible to eliminate the necessary reduction of power without increasing the loss of material; important flammable and biostable materials. The wood has been modified in a thermo-chemical way, it is made up of furniture, furniture and furniture.

When modifying the tree by a radioactive-chemical method, polymerization of the introduction to the village of rechovins is brought into the water by the infusion of ionizing vipromynuvans. Permeate the wood with methyl methacrylate, styrene, vinyl acetate, acrylonitrile and other monomers, as well as sums. Robots carried out at the Institute of Physics and Chemistry. V.L. Karpov, showed that such a way of modifying the shape, mechanical and exploitation of the power of the tree. The tree has been modified for vikoristovuyutsya for the preparation of parquet, machine parts and other purposes.

When chemically modifying the tree, it is made with amyakom, anhydride, or other words, so that the fine structure and chemistry warehouse can be changed. The processing of amiakom increases the pliability of the tree, from which the tree grows self-sustained when dry, changes in color. To carry out the processing of ostovym anhydride with the help of acetylating wood, so that the acetyl groups are introduced to the warehouse of chemical components. Acetylated tree does not have a lot of mechanical power to shrink, but water and clay, swelling and shrinkage diminish. Acetylivan village is completely vicarious in the preparation of virobes with an increased form stability. Robotization in the wood acetylus was carried out at the Latvian Sylkogospodar Academy.
