NON-COMBUSTING/SEMI-NON-COMBUSTING METHOD OF WOOD, NON-COMBUSTING CHEMICAL LIQUID OF WOOD AND NON-COMBUSTED/SEMI-NON-COMBUSTED WOOD

摘要

PROBLEM TO BE SOLVED: To provide a non-combusting/semi-non-combusting method of wood, a non-combusting chemical liquid of wood used in the non-combusting/semi-non-combusting method and non-combusted/semi-non-combusted wood non-combusted/semi-non-combusted by the non-combusting/semi-non-combusting method.;SOLUTION: The non-combusting/semi-non-combusting method of the wood has a process for immersing air-dried wood with a water content of 20% or below in the non-combusting chemical liquid comprising an aqueous solution of a nitrogen phosphate compound to penetrate the non-combusting chemical liquid in the wood and a process for drying the impregnated wood. As the nitrogen phosphate compound, guanidine phosphate is used. The non-combusting chemical liquid is prepared using phosphoric acid as an auxiliary agent other than guanidine phosphate and the weight ratio of water, guanidine phosphate and phosphoric acid is set to 100:15-70:0-20.;COPYRIGHT: (C)2007,JPO&INPIT
