【摘要】 住宅用途的木材防腐剂正逐步走向包括微粒铜在内的新复合防腐剂体系,及无重金属的全有机体系。为了提高这些新防腐剂的性能,一类称为性能增强添加剂已经开发出来,如水分控制稳定剂,表面活性剂和乳化剂,防霉剂和着色剂等;针对人们对于化学防腐剂处理的木材越来越负面的看法,以及监督管理的审查和限制的加强,一些非传统的木材保护体系形成,如阻隔保护体系,化学改性和非化学改性,天然耐久树种木材也出现。笔者在文中对这些问题进行了回顾和讨论。更多还原

【Abstract】 Due to voluntary cancellation of CCA registrations for residential uses,wood preservatives for residential applications are moving towards new complex preservative systems including micronized copper formulations and heavy metal-free,totally organic systems.In order to improve the performance of these new preservatives,known as performance-enhance additives have been developed,such as moisture control stabilizers(MCS),surfactants and emulsifiers,anti-mold agents and coloring agents etc.Because of an increasingly negative perception of chemical-treated wood to the public,and the reality of increased regulatory scrutiny and restrictions,some non-traditional wood protection systems,such as barrier protection system,chemical modification and non-chemically modification,as well as naturally durable wood species etc have turned up.All of these issues are reviewed and discussed in this paper.更多还原
