采用锥形量热法(CONE)和热重分析法(TG)比较研究氯化锰和碳酸锰处理木材的燃烧、发烟和成炭特性.结果表明,在木粉中添加10％氯化锰或碳酸锰热压胶合制备的阻燃木材试样的总热释放量(THR)比未处理木材分别降低了39．4％和24．3％,总烟释放量(TSP)分别降低了93．3％和31．2％,CO 平均释放量(m-COY)分别降低了27．0％和8．1％,这说明两种锰化合物对木材均具有阻燃、抑制烟雾和毒气的作用,氯化锰的这种作用更显著.锥形量热和热重数据结合残余炭形貌电镜照片分析表明氯化锰在高温条件下催化木材形成更多的炭,而且炭层结构更加紧密和稳定,从而有效降低木材的燃烧释热速率和烟气生成速率,降低木材引发火...

Manganese has catalytic action on many chemical reactions, however, whether manganese compounds have the effects of flame retardant and smoke suppression was not clear. CONE and TG were used to analyze the combustion properties, smoke-release properties, and carbonization characteristics of liriodendron treated by two important inorganic manganese compounds-manganese carbonate and manganese chloride. The results show that: relative to the untreated wood panels, the THR of wood panels treated with two manganese compounds respectively decreased by 24.3% and 39.4%, TSP decreased by 31.2% and 93.3...
