摘要:

用木材化学改性剂(LM)改性木材(杨木,马尾松等),当木材化学改性剂增重(WPG)达20%-30%时,可获得很高的抗缩系数(ASE值)或尺寸稳定性。改性后木材具有良好的防腐、防白蚁、防霉,防蓝变的性能,并且还可获得很高的阻燃性能。用木材化学改性剂(LM)改性后的木材无毒(LD50 > 10000mg/kg),无味,对人,畜无害。

Abstract:

Lumbers (poplar, pine etc.) treated with chemical modifying agents(LM) possess a high antishrink efficiency (ASE) at 20 to 30 chemical weight percent gains (WPG). The modified wood has broad range efficiency against mold, termite, sapstain and decay fungi. It shows a high degree of fire retadancy. Wood treated with chemical modifying agents (LM) has been proved through examinadons that it's toxicity LD50 is more than 10000mg/kg; so it cause no harmful effect to people and domestic animals.
