Abstract RU 2622706 C1

FIELD: woodworking industry.

SUBSTANCE: wood chips are ground. Processing aids are introduced into the wood fibre pulp. Mat moulding, dehydration and hot pressing are performed. During the grinding process, in the wood chips, plasticizing additive is introduced in the amount of 0.3-4.5% by weight of dry fiber. In the process of the mat dehydration, in the wood fibre pulp with concentration of 5-9% processing aids are introduced. During mat moulding, the face finishing layer is formed, into which the processing aids are introduced.

EFFECT: increased strength and water resistance of the board.
