为了防止苯对工人的危害,铁道部浦镇车辆工厂,采用毒性较低以二氯甲烷为主要原料的脱漆剂代替苯为主要原料的脱漆剂,并在铁道部内工厂推广。近年来在使用中,工人反映有头昏、头晕、眼部刺激、咽喉发干、食欲下降等症状。为了解其毒性,我们对该厂脱漆剂中二氯甲烷的组分进行了分析,并将其急性毒性与纯品二氯甲烷的急性毒性进行了初步的研究和比较。实验材料和方法一、测试样品脱漆剂中二氯甲烷分别用甲厂—1978年12月、乙厂—1979年5月、丙厂—1979年4月出厂的产品。三厂产品以下简称脱漆用品。纯品二氯甲烷:规格A.R,系江苏无锡查桥化工厂生产:批号770402,以下简称纯品。苯:规格A.R,系上海试剂一厂生产,批号72-11-31。
In order to prevent the harm of benzene to workers, the Ministry of Railways Puzhen Vehicle Factory adopts the paint remover with low toxicity as the main raw material instead of benzene as the main raw material, and popularizes the factory in the Ministry of Railways. In recent years in use, workers have dizziness, dizziness, eye irritation, dry throat, loss of appetite and other symptoms. In order to understand its toxicity, we analyzed the composition of methylene chloride in the paint remover of the factory and conducted preliminary research and comparison on its acute toxicity and the acute toxicity of pure methylene chloride. Experimental materials and methods First, the test sample paint remover methylene chloride respectively with a factory - December 1978, B plant - May 1979, B plant - April 1979 manufactured products. Three factory products hereinafter referred to as stripping supplies. Pure methylene chloride: Specifications A.R, Jiangsu Wuxi Chaqiao Chemical Factory production: batch number 770402, hereinafter referred to as pure. Benzene: Specifications A.R, Department of Shanghai Reagent Factory production, batch number 72-11-31.
