热处理马尾松木材的防霉变处理方法预筛选

Pre-screening of Anti-mildew Methods for Heat-treated Masson Pine Wood

马尾松(Pinus massoniana)热处理材不具备防霉变效力,且较未热处理材更易发生霉变,为了其推广应用的健康,需采用技术手段提升其防霉变效力。马尾松热处理木材经抽提后,其霉变防治效力均未超过75%;5%硼化物先预处理木材,再以180、200、220 ℃分别热处理1、3、5 h,其获得的最高霉变防治效力为41.7%。预处理在一定程度能够增强马尾松热处理材的霉变防治效果。

Heat-treated masson pine wood does not have anti-mildew effect.In order to be beneficial in application,technical measures should be adopted to improve its mildew prevention effect.After the heat-treated masson pine wood was extracted,its mildew prevention effect was not more than 75%.Wood was chemically pre-treated,then treated at 180-220 ℃ for 1-5 h respectively,the highest anti-mildew effect was 41.7%.Pre-treatment or post-treatment can enhance the mildew control effect of heat-treated masson pine wood to a certain extent.
