The paper presents the results of studies to establish the influence of technological and constructive parameters of the process of producing a wood-fiber mass in the manufacture of flame retardant hardboard on the physico-mechanical properties of finished products while maintaining the latter at the required level. For the task solution in the work there were used methods of mathematical planning with the aim of obtaining the mathematical description of grinding process of wood-fiber mass during the manufacture of hardboard panels with a reduced fire hazard. Construction of mathematical models of object is an important part of scientific research. Developed mathematical model of the object are a good research tool. Obtained equations describing the studied processes of preparation of wood-fiber materials, and adequate, in our view, allow for obtaining high-quality MDF panels with a reduced fire hazard depending on the set modes of the milling process. At known values of the mass fraction of expanded vermiculite in wood-fiber composition and by changing the values of constructive and technological parameters of the refining units, it is possible not only to reduce the inflammability level of the slabs according to GOST 12.1.044-89 "fire and explosion hazards of substances and materials. Nomenclature of indices and methods of their determination" to the level of flame retardant, but also to maintain physical and mechanical properties of solid wood-fiber plates within the requirements of GOST 4598-86 "fiberboard Plate. Technical conditions".
