去年,我们接收了2,000多卷(册)旧政权档案资料,这些档案资料受害虫侵蚀较为严重,少数案卷巳被蛀成碎片。为了防止虫害的扩散,我们采用化学药剂——磷化铝熏蒸杀虫法,将害虫全部杀死。一年后复查,没有发现任何异常情况,档案的纸张、字迹也没有受到不良影响。我们认为,这是一种操作简便、效果显著的杀虫方法。杀虫原理及特性磷化铝(AIP)片剂吸潮分解后产生磷化氢。磷化氢是一种剧毒气体,气体通过害虫呼吸器官渗透到虫体的血液,或通过体壁进入虫体组织,致使害虫中毒死亡。其反应 Last year, we received more than 2,000 volumes of old regime files, which were more eroded by pests and a few cases were splintered. In order to prevent the spread of pests, we use chemical agents - aluminum phosphide fumigation insecticide law, all the pests killed. One year after the review, did not find any anomalies, the paper records, writing has not been adversely affected. In our opinion, this is a simple and effective insecticidal method. Insecticidal Principles and Features Phosphide (AIP) tablets produce phosphine after hygroscopic decomposition. Phosphine is a highly toxic gas, the gas penetrates into the bloodstream of the insect body through the respiratory organ of the insect pest, or enters the insect body tissue through the body wall, resulting in the poisoning of pests. Its reaction
