As a result of work it is established that decrease in temperature of a veneering with 85 to 60 0C positively influences reduction of a deflection of boards. Use of polyvinyl acetate disper-sion of various viscosity of essential influence on a deflection and durability of glue connection doesn´t render. Taking into account a deflection and durability of glue connection the best results are received at a veneering of a furniture board with use of high-viscosity dispersion at a temper-ature of 60 0C, pressure of 0.7 MPa and duration of endurance in the press of 52 seconds.

One of the main objectives of the enterprises for production of furniture is decrease in a material capacity of production and as a result decrease in its prime cost. Producers of kitchen table-tops for this purpose pass to production of table-tops of the combined design, replacing thick wood-shaving plates 25, 38 mm thick, with thinner 16 mm.For maintenance of more massive appearance of such table-tops to thin wood chipboard in the longitudinal direction at the edges of a board paste longitudinal strips from chipboard. The economy of material can lead to a deflection, the received table-tops. In this work the deflection of table-tops of the combined design was investigated. For studying of the reasons of emergence of a deflection and ways of its decrease the samples received in laboratory and working conditions were investigated. For pasting of boards from chipboard the paper and layered plastic used glue on the basis of polyvinyl acetate dispersion and the combined glue with various ratio of urea-formaldehyde resinand polyvinyl acetate dispersion. At the first stage defined a deflection of not revertedwood-shaving plates. Then controlled change of a deflection after gluing of plastic, paper from the back (and, paper and plastic made a veneering consistently and at the same time), after gluing of levels from chipboard. The deflection was defined in various directions of a furniture board in dynamics. Determined durability of gluing of plastic by above-mentioned glues. As a result of work it is established that the veneering of the front and reverse parties of plates in a hot press needs to be made at the same time. By production of the combined design of table-tops it is more expedient to use pure polyvinyl acetate dispersion. Durability on a plastic separation from wood-shaving plates is higher when using of the mixed glue on the basis of polyvinyl acetate dispersion and urea-formaldehyde resin.

The possibility of applying nanocellulose as additive in the production of plywood is considered. This involves its activation by physical methods (ultrasonic treatment and PMF). Increase in the strength of the resulting material by increasing the strength of the adhesive joint is experimentally established. But in this case, the strength of the adhesive joint was higher the strength of birch veneer sheets, veneer pack was amplified with basalt material. Studies have also shown that replacement of the two plies on the basalt fabric beneath the outer layers of plywood, gives an increase in tensile strength by adhesive seam compared to the control sample by 220 %.

The paper discusses the features of design and technology of finger joints in the manufacture of frame-paneled platings of doors and furniture fronts. At the design stage we solve two problems: a) the choice of shapes and sizes of studs and grooves according to GOST R 9330, b) calculation of probabilistic values of the maximum deviations of landings with interference by GOST 6449. It was proposed to abandon the finger joints, restrict ourselves to assembly in tongue and groove, so with conjugation in counterprofiles groove is milled on the ends the horizontal bars after pre-pruning to eliminate chipping and tongue - on inner shared edge of vertical bars.

One of the topical issues of the application of furniture in domestic premises is defining its limiting (maximum) saturation in the premises so that the air in these premises, the allocation of harmful substances does not exceed the maximum allowable level (maximum permissible concentrations - MPC). It is known that in using furniture of wood-based panels (particle Board, Chipboard, wood fiber, MDF) this substance is formaldehyde. Currently, the MoH established the formaldehyde MPC in the air at the level of 0.01 mg/m3. The aim of this work was to determine the limit of saturation with the wood plates in premises, provided that indoor formaldehyde emissions from plates will not exceed the established by the Ministry of health MPC. This definition of the limit of saturation (Ls, m2 of plates/m3 of the premises air) was performed according to our previously derived formula. Calculations were made for furniture (cabinet furniture, tables, beds of panel design, furniture for sitting and lying, beds with soft headboards and elements), floor coverings and wall panels. In the result, it was found that, for example, when using chipboard of E1 formaldehyde emission class in designs of furniture, tables, beds of panel construction value of Ls when the IISP is 1.0 m2/m3 of air (saturation of the volume of air with plates in their testing by chamber method) and MPC=0.01 mg/m3 is 4.03 m2 /room, and when MPC=0.124 mg/m3 (adopted by the countries-participants of the WTO and the World Health Organization) it will make 50.05 m2/room. When using plates of the same emission class, and for the same value of IISP, when MPC=0.01 mg/m3 Ls value is 6.25 m2 /room, when MPC=0.124 mg/m3 it will make 77.63 m2 /room. When using E1 class chipboard panels in the construction of furniture for sitting and lying, beds with soft headboards and elements, Ls value in the IISP is equal to 0.3 m2/m3 air and at MPC=0.01 mg/m3 is of 1.21 m2 /room, and when MPC=0.124 mg/m3 it will make 15.02 m2/room. When using plates of the same emission class, and for the same value of IISP at Mac=0.01 mg/m3 Ls value is 1.88 m2/room, when MPC=0.124 mg/m3 it will make 23.45 m2/room.
