去年,辰溪县档案馆对馆藏的全部档案进行了磷化铝、氯化苦混合熏蒸,收到了较好的效果。混合使用磷化铝、氯化苦有利于药物毒气作用的发挥,消毒杀虫干净、彻底。熏蒸剂毒效取决于药剂本身,而每种药物的理化性质不同,产生毒效的范围、程度就有差异。也就是说它们的挥发性、扩散性、钻透性不同,混合使用正好起到互相补充的作用。磷化铝在空气中的表面积越大,其挥发性就越大。施药时,我们把磷化铝平摊在瓦片上,扩大了药剂的挥发能力。同时,磷化铝沸点低(—87.5℃),挥发迅速,其投放库房后,遇空气中的水份则急剧分解产生磷化氢。磷化氢这种气体刺激害虫呼吸器
Last year, Chenxi County Archives of all the files were archived aluminum phosphide, chloropicrin mixed fumigation, received good results. Mixed use of aluminum phosphide, chloropicrin is conducive to the role of drug gas play, disinfection clean, thorough. Fumigation agent toxicity depends on the agent itself, and each of the physical and chemical properties of different drugs, to produce toxic effects range, there are differences. In other words, their volatility, diffusivity, permeability of different, mixed use just play a complementary role. The larger the surface area of aluminum phosphide in the air, the greater its volatility. When spraying, we flatten the aluminum phosphide on the tile, expanding the volatility of the drug. At the same time, the low boiling point of aluminum phosphide (-87.5 ℃), volatile quickly, after the release of the Treasury, the case of water in the air is rapidly decomposed to produce phosphine. Phosphine is a gas that irritates pest respirators
