我国北方农村的建筑用材,多以杨、柳、榆等速生树种为主,但这些木材易发生腐朽与虫蛀。本课题对适合农村建筑中杨木等木结构的防腐、防虫剂和防腐涂料的物理化学性能,对菌、虫毒效等进行了一系列的室内外试验,提出了简易的防腐防虫处理方法。在试验基础上,选用效果较好的水溶性、油溶性防腐、防虫剂和防腐油漆,并进一步在北京大兴县农村进行了扩大应用试验。经两年多观察,尚未发现虫蛀与腐朽,但未防腐的檩条已发生虫蛀。
China’s northern rural construction timber, and more to Yang, Liu, Yu and other fast-growing tree species, but prone to decay of these wood and moth-eaten. In this paper, we carried out a series of indoor and outdoor experiments on the anticorrosive, anti-insect and anti-corrosion coatings of poplar wood and other anti-corrosion coatings in rural buildings, and conducted a series of indoor and outdoor tests on bacteria and insects, and put forward a simple method of anti-corrosion and pest control. Based on the experiment, water-soluble, oil-soluble preservatives, insect repellents and anticorrosive paints with good effects were selected, and an expanded application test was carried out in rural Daxing County, Beijing. After more than two years of observation, we have not found moth-eaten and decayed, but the non-preserved pomfret has been moth-eaten.
