摘要

为提高木材防腐处理效果，研究了温度和时间对ＣＣＡ在马尾松中固着的影响。结果表明，提高温度，可显著提高ＣＣＡ的固着率，在室温（１５～１７℃）、处理３００小时，固着率为９２％～９４％，而７０℃时，仅２１～４５小时即可达到９５％～９８％。采用热湿空气（７０℃，ＲＨ８０％～８３％）只需９～１２小时可使ＣＣＡ完全固着。此法可以减少ＣＣＡ可能带来的环境污染，简便可行，提高生产效率

Abstract

The effect of both treatment temperature and time on CCA fixation in wood was experimentally investigated in order to improve the fixation in CCA treated wood.The results showed that the CCA fixation rate in wood increased rapidly with a rise of temperature.It took 300 hours for 92%～94% fixation rate at ambient temperature(15～17℃)and 21～45 hours for 95%～98% at 70℃.Furthermore,it took only 9～12 horus for a complete CCA fixation by hot wet air heating process (70℃, RH 80%～83%) This process could be operated easily and can be used to reduce environmental pollution from CCA treated wood and improve the production efficiency.
