    • Disclosed is a method for the chemical treatment of woods, which comprises introducing a chemical solution into a pressure vessel charged with wood so that the wood is entirely dipped in the chemical solution, heating the chemical solution to a temperature within the range not causing high temperature troubles in the wood, and elevating the pressure in the pressure vessel above the saturated steam pressure to cause the chemical solution to permeate into the wood.According to this method, the chemical permeation treatment can be accomplished in a very short time at a low temperature not causing high temperature troubles in woods. Furthermore, the preliminary boiling treatment, which is indispensable in the conventional method, can be omitted.
    • 公开了一种用于化学处理木材的方法,其包括将化学溶液引入装有木材的压力容器中,使得木材完全浸入化学溶液中,将化学溶液加热到不引起高温的温度 木材中的麻烦,并使压力容器中的压力升高到饱和蒸汽压力以上,使化学溶液渗透到木材中。 根据该方法,化学渗透处理可以在低温下的非常短的时间内完成,而不会导致木材中的高温问题。 此外,可以省略在常规方法中不可缺少的预沸处理。
