Effects of Extraction Treatments on Tangential Section Interface for Wood of Castanopsis Fissa
LI Nian-cun · China Wood-based Panels · 2005
Effects of different extraction treatments on performance of tangential section interface were tested for wood of Castanopsis fissa.The results showed :the contact angle of water drip on the tangential section interface of the specimen increased and the free energy on it decreased after the specimen was treated in organic solvent or water of different temperatures ,while the contact angle of water drip on the tangential section interface of the specimen decreased and the free energy on it increased after the specimen was treated in alkali solvent.This proved the performance of the tangetial section interface of wood of Castanopsis fissa could be controlled by proper extraction treatment to improve its permeability and gluing property.
