METHOD OF ESTIMATION OF WATER-MOISTURE ABSORPTION OF WOOD COMPOSITE MATERIALS Russian patent published in 1998 - IPC

Abstract RU 2104862 C1

FIELD: woodworking industry, production, for instance, of wood composite materials protected against inflammation, such as, plywood, laminated plastics, etc. SUBSTANCE: estimation of water-moisture absorption of wood composite materials consists in determination of the value of the sought parameter as a relation between the mass of moisture absorbed by the material and the initial mass of the material specimens; the value of the sought parameter is additionally changed to the relation between the variation of the mass of the water-soluble component and the initial mass of the material specimens. This makes it possible to take into account the influence of the water-soluble component on the value of water-moisture absorption of wood composite materials, which in the range under analysis may considerably distort the value of water-moisture absorption of the material determined as per St.Stnd.GOST9621. EFFECT: facilitated procedure. 4 tbl
