CHEMICALLY TREATED WOOD PARTICLE BOARD

A method of making a borate treated wood particle board by applying an adhesive resin and a particulate borate treating agent (anhydrous borax or zinc borate) in a dry form to the wood particles to produce treated wood particles (wafers). The treated wood particles are formed into a mat and consolid...

Zusammenfassung:	A method of making a borate treated wood particle board by applying an adhesive resin and a particulate borate treating agent (anhydrous borax or zinc borate) in a dry form to the wood particles to produce treated wood particles (wafers). The treated wood particles are formed into a mat and consolidated under heat and pressure to distribute the resin in the wood before the viscosity of the resin is effected by contact with a sufficient amount of borate to significantly impair penetration of the resin into the wood.
