引言木材含水率高于20％时,大部分浅色硬木和软木易受霉菌和蓝变菌的侵害。为了保护这些浅色硬木,试用了一些化学药剂进行处理。尤其对于蓝变菌和霉菌较敏感的木材,这些处理愈加重要。目前,马来西亚广泛使用的氯化苯酚钠盐,当与杀虫剂混合使用时,对真菌有很高的毒性,并且还能防治虫害。五氯酚(PCP)对人和动物有毒害。由于对这类药剂毒性的担心,以及石油基的产品成本增高,因而提高了该农药的成本。因此,
Introduction When moisture content in wood is above 20%, most light-colored hardwood and softwood species are susceptible to mold and blue-green algae. In order to protect these light-colored hardwoods, try some chemicals for handling. Especially for the blue-sensitive bacteria and mold more sensitive wood, these treatments become more important. At present, the widely used sodium chlorpheniramine salt in Malaysia, when used in combination with insecticides, is highly toxic to fungi and can also control pests. Pentachlorophenol (PCP) is toxic to humans and animals. Concerns over the toxicity of such agents and the increased cost of petroleum-based products have increased the cost of the pesticide. therefore,
