橡胶木极易受到蓝变菌和霉菌的侵害 ,须进行预防性保护处理。目前我国使用五氯酚钠 (NaPCP)控制和防止蓝变和霉变的产生 ,但自从发现氯代酚类化合物中含有致癌的二恶英类化合物后 ,此类化合物就逐步被世界大多数发达国家和一些发展中国家禁止使用了。自 2 0世纪 80年代开始 ,环保型防变色剂预防木材蓝变和霉变的研究和开发在国际上开展的十分广泛。本文研究了不同浓度的Antiblu防变色剂预防橡胶木和Parachem、硼类防腐剂加压处理的橡胶木锯材的防变色效果。选取了橡胶木新鲜锯材 6 5 0根 ,分为 13组 ,每组 5 0根。其中 1组 (o组 )不用硼防腐剂进行防腐加压处理 ,也不进行防变色处理 ,作为试验对照组。 4组(a、b、c、d组 )不用硼防腐剂进行防腐加压处理 ,只用防变色剂浸沾处理。另 4组 (e、f、g、h组 )先用硼酸 硼砂防腐剂进行防腐加压处理 ,再用防变色剂浸沾处理。其余 4组 (i、j、k、l组 )先用Parachem橡胶木防腐剂进行防腐加压处理 ,再用防变色剂浸沾处理。其中 ,a、e、i 3组用相对体积质量 1 0 %的Antiblu 2 0EC浸沾处理 ;b、f、g3组用相对体积质量 1 5 %的Antiblu 2 0EC浸沾处理 ;c、g、k 3组用相对体积质量 2 0 %Antiblu 2 0EC浸沾处理 ;d、h、l 3组用相对体积质量 1 5 %的Antiblu 2 0EC +0 12
Rubber wood susceptible to blue-green bacteria and mold damage, to be preventive protection. At present, sodium pentachlorophenate (NaPCP) is used in our country to control and prevent the occurrence of blue-change and mildew. However, since the discovery of carcinogenic dioxins in chlorinated phenolic compounds, such compounds have been gradually developed in most of the world Countries and some developing countries banned their use. Since the 1980s, the research and development on the prevention of blue-change and mildew-resistant wood from environment-friendly anti-tarnish agents has been carried out in a wide range of countries. In this paper, different concentrations of Antiblu anti-discoloration agent to prevent rubber wood and Parachem, Boron preservatives pressurized rubber wood sawdust discoloration effect. A total of 650 fresh rubberwood logs were selected and divided into 13 groups of 50 each. One group (o group) did not use preservative and boron corrosion preservative pressure treatment, nor for discoloration treatment, as a test control group. 4 groups (a, b, c, d group) without preservatives preservative pressure treatment, anti-tarnish only soaking treatment. The other 4 groups (e, f, g, h group) were first treated with borax preservative and anti-corrosive pressure, and then treated with anti-tarnish dip. The remaining four groups (i, j, k, l) were treated with Parachem rubber wood preservatives and treated with anti-tarnish agent. Among them, a, e, i 3 groups were treated with Antiblu 2 OEC with a relative volume of 10%, while groups b, f and g were immersed with Antiblu 2 OEC with a relative volume of 15%; c, g, k Three groups were treated with 20% Antiblu 2 OEC soaked in relative volumetric mass, Antiblu 2 0EC +0 12 with relative volume mass of 15%
