防腐处理竹材的室内抗腐性试验

选用经五种防腐药剂处理过的淡竹进行室内抗腐性试验,同时选用毛竹做室内天然耐腐性试验。结果表明:用热冷槽法,浓度为5%的“BB”和3%的“BBF”防腐效果较好,采用浸渍法,浓度为5%的“BP”、“CCB”“FCAP”均具有防腐效力,浸渍时间19天为宜。毛竹的天然耐腐性较差,与木材相比毛竹在较低的重量损失率(20%)下就丧失使用价值。而木材在同等重量损失率范围内则属于稍耐腐或耐腐等级。

A study on interior antidecay test of preserved bamboos

Choosing bamboos (Phllostachys henonis) treated with five agents as test materials, the experiments on decay resistance efficiency of the agents have been done. The results have been showed in the paper.Using hot and cold bath proces, the bamboos treated with the concentration of 5% f BBand concentration of 3% of BBF have better antidecay efficiencies. Using soaking methods, the bamboos treated with 5% of BP, CCB, FCAP have better efficiencies of antidecay. The soaking time is good for 19 days.The antidecay of natural bamboos (Phyllostachys pubescens) is worse than natural wood When having the 20% weight lossing rate, the bamboos have lost their worth of utilization. While at the same rate, using of wood is effected to some extent.
