METHOD FOR MANUFACTURE OF WOOD-PARTICLE BOARDS Russian patent published in 1998 - IPC

Abstract RU 2103164 C1

FIELD: woodworking industry. SUBSTANCE: method includes preliminary calculation of process parameters for manufacture of wood-particle boards with preset properties. Introduced into system of regression equations are preset parameters of properties. Then with consideration of weight coefficients, additive function is obtained and by subsequent multicriteria optimization, optimal parameters of the process are determined, and they are taken as preset ones for process control device. Carried out in the course of continuous control is measurement of present humidity of resinified chips of middle and facing layers, weight of chip briquettes, press plate temperature, time of board holding in press at maximum pressure, time of smooth drop of pressure, time of holding boards in press at no pressure, and time of the whole cycle of pressing. Then obtained results are compared with the preset optimal values and regulation of speeds of batching conveyors of molding machines is based on the obtained results of comparison. EFFECT: higher efficiency. 1 dwg, 3 tbl
