Description

(3) METHOD OF MANUFACTURING FACILITATED PRODUCTS FROM WOOD PRESS MASS The invention relates to methods for producing veneered products. And can be used in the wood-processing industry. A known method for manufacturing lined articles from a woody press mass includes forming a bag of woody press mass and paper impregnated with a solution based on a thermosetting resin, followed by pressing 1. The disadvantage of the method is the poor quality of the curved surface facing. A known method of making veneered wood products. . press mass, including the formation of a package of wood press mass and paper impregnated with a solution based on a thermosetting resin and oleic acid, followed by pressing C2 3. Thac; the method does not provide a qualitative lining of the curved surface, since oleic acid does not mix with the water solution of the resin, depositing drops on the surface of the lining layer and forming a patchy surface. In addition, in this method, the olein slot is inserted into the promexual paper layer located between the press mass and the front layer of paper, which does not improve the anti-adhesion properties of the facing material. The purpose of the invention is to improve the quality of the surface of the coated products and impart anti-adhesive properties to them by uniformly distributing oleic acid in solution. The goal is achieved by the fact that the proposed solution additionally introduces the surfactant linozolin 7-9 in an amount of 0.5-1.0 wt.%. The impregnating composition for the facing layer is prepared as follows.

With continuous stirring, an oleic acid and a surfactant linosolin 7–9 are added to the impregnating solution of a resin of the MMPT brand according to TU 13 USSR 2-78. The wood press material consists of BB% chips and 12% of the binder (KF-MT-P carbamide-formaldehyde resin.) The co-solution is impregnated with Fo on the molds.

Tav impregnating composition is listed in the table. To impregnate texture paper with a density of 150 g / m on THE 81-OA-501 -77.

S This wood-adhesive composition with a cladding layer is used to form boxes of 12SOx mm.
