Lelyuk D. The effect of thermic processing of partical boards on their physical, mechanical and ecological characteristics

An object is the mechanism of heat treatment of particle boards. A purpose is determination of heat treatment of particle boards behavior on their physical and mechanical and ecological indexes. Methods - the standardized methods of particle boards testing have been used for determination of physical and mechanical indexes. The numerical methods of multidimensional tasks of heat exchange and heat transfer solution have been applied for particle boards. Scientific novelty: method of particle boards have been justified. Physical and mathematical model of heat conductivity of particle boards in the process of its heat treatment have been developed for the first time under which the temperature of boards in the process of their heat treatment has been determined after. Results: empiric formulas for description of heat treatment on physical and mechanical properties and ecological indexes of particle boards. The optimum values of temperature of heat temperature of heat treatment conducting and duration of process have been found. The principle chart of drying kiln for heat treatment of particle boards has been recommended. Degree of introduction: The use of results of research will allow on Nadvirna forest mill, only due to the increase of grade of деревинностружкових flags, to get an economic effect 28912 UAH Industry is woodworking.
