Fixation of Heavy Compression Deformation of Wood Treated with Polycarboxylic Acids
Polycarboxylic acids acts as esterification agents and inorganic salts acts as catalyst in wood crosslinking reaction.A new water soluble non formaldehyde crosslinking system was composed of these two chemicals with characteristics of poison free and pollution free.This paper discussed permanent fixation of heavy compression deformation of wood by using the system.Recovery of Populus ussuriensis wood treated with 1,2,3,4 butanetetracarboxylic acid (BTCA) with 9% concentration was very low in dry condition.Recovery was nearly 27.01% by immersion in boiling water.The specimen were permanently fixed with the system by suitable concentration,e.g.9%.Surface color of the specimen slightly varied from red to yellow.
