三种国外木材防腐剂室内防腐防霉防白蚁性能评价

Evaluation of the Effectiveness of 3 Foreign Wood Preservatives against Decay Fungi, Moulds and Termites

不含铬和砷的TanalithCuAz、TanalithCY和TotimB是目前国外广泛应用的环保型木材防腐剂产品。本文 报道了这3种国外木材防腐剂产品的首次国内室内防腐性能评价试验的结果。结果显示,用少量TanalithCY和 TotimB产品即可有效地抑制腐朽菌对木材的侵害;TanalithCuAz对腐朽菌的抑制效力随其浓度的增加而快速增 大;TanalithCuAz和TotimB分别显现出良好的抑制白蚁、防止蓝变菌及霉菌侵染的功效。

Three kinds of preservatives, Tanalith CuAz, Tanalith CY and Totim B, being free of chromium and arsenic, are now widely used abroad as environmentally-friendly wood preservatives. Their popularity has been increasing due to their nontoxic components to humans and animals. This paper reports the first laboratory evaluation in China against decay fungi, moulds and termites for these three foreign wood preservatives. The results show that both Tanalith CY and Totim B can effectively prevent wood decay with a low retention level; the preservative effects of Tanalith CuAz to decay fungi increases dramatically by increasing its retention level. Tanalith CuAz and Totim B also have excellent resistance to termites and moulds on wood respectively.
