摘要
TWP防腐剂以满细胞法处理的橡胶木,经露天气干2至9个月,用试剂显色法测定药剂透入深度。对4～6cm厚的板材药剂全部渗透,外层15mm硼酸当量(BAE)占木材绝干重0.20%以上。经耐腐性试验测定,用TWP处理的橡胶木属耐腐级,但野外耐腐性较差。此外。
The decay resistnaee of the rubber wood treatedo with preservative TWP by full-cell process was tested after 2～9 months airseasoning. The resuits showed that the board with 4～6cm in thickness was fully penetrated by TWP with a loading of BAE (Boric Acid Equivalent) over 0.2% (w/w) in the outer part with a thickness of 15mm. The durability of the treated wood was raised to durable grade, but the decay resistance was relative poor in field. The effect of different penetration depth on decay resistance of treated board was also studied.
