Wood particle boards, as well as the construction and finishing materials based upon wood particle boards are traditionally used in increasing volumes in the construction works and furniture industry. The limitations prescribed in Russia are connected with the maximum permissible concentration of uncombined formaldehyde (СН2О) in the living space. One of the possible ways of solutions of this problem is the using of acceptors. The main idea of this paper was researching the effectiveness of new acceptor – modified amidophosphate, serving to reduce СН2О content in the wood particle boards products without loss of base indices. The acceptor adhesive interaction influence in wood particle boards has been studied. The selection of overall product consumption is carried out. It has been established that the use of suggested acceptor will make it possible to produce wood particle boards with СН2О content less than 4 mg/100 g abs. dry board. This ratio of СН2О is permissible to use wood particle boards in the manufacturing of the kids furniture and furniture for medical and educational institutions as well as for the conformance to the requirements of the leading foreign companies. The experimental-industrial output of board batch in volume 250 m3 is carried out in the department Cherepovetsky PFGE at the press «Dieffenbacher». The characteristics of the manufactured production, corresponded to the standards at the base indices and СН2О content are reported. The optimum expense of acceptor is established.
