橡胶木的防变色试验

Experiment on Protection of Rubberwood from Blue Stain and Mould

通过不同浓度的不同防变色剂分别对未处理和经过硼防腐剂和 Parachem防腐剂加压处理的橡胶木锯材进行浸沾处理 ,对其防变色效果进行了研究。结果表明 ,无论经过硼防腐剂处理与否 ,用防变色剂进行短时间 (30 s)的浸沾处理 ,均可有效地防止橡胶木的蓝变和发霉 ,保护期可达 4周以上。

The experiment was to find out an environment friendly preservative to protect the Rubberwood (Hevea brasiliensis) from blue stain and mould. Chemicals used to treat the Rubberwood were borax and boric acid, Parachem, Antiblu 20EC and Antiborer 10EC. Results showed that the permanence of the preservative of Antiblu 20EC could least four weeks regardless of the Rubberwood treated with or without borax and boric acid, and three months for the Parachem treated Rubberwood. The Rubberwood could be well protected by pressure treatment with the preservative of boride and half minute infusion treatment with Antiblu 20EC.
