1976年,我们对××电筒厂173名(以下简称Ⅰ组)和××电镀厂437名电镀作业工人(以下简称Ⅱ组)进行了预防性体检及生产流程的了解,结果分析如下。一、接触毒物及生产流程 1.××电镀厂主要接触毒物有:氰化钠、硫酸、盐酸、硝酸、纯碱、硫酸镍、硫酸铜、氰化亚铜、硝酸钾、铬酸、铬酐、活性碳等。其生产流程是: 毛胚→上挂具→电解除油→清洗→过酸→预镀→清洗→焦磷酸盐镀壳铜(?)镀壳镍→清洗→镀铬→清洗→热水浸→下挂具→检验→成品。生产环境及产品: 本厂车间较集中,车间有通风设备,工作点
In 1976, we conducted preventive medical examination and production process for 173 electroplated workers (hereinafter referred to as Group Ⅱ) from 173 employees (hereinafter referred to as Group Ⅰ) of ×× Flashlight Factory and ×× Electroplating Factory. The results are analyzed as follows. First, the contact poison and the production process 1. × × electroplating main contact poison: sodium cyanide, sulfuric acid, hydrochloric acid, nitric acid, soda ash, nickel sulfate, copper sulfate, cuprous cyanide, potassium nitrate, chromic acid, Activated carbon and so on. The production process is: the embryo on the hanger → Electrolysis degreasing → cleaning → peracid → pre-plating → cleaning → pyrophosphate plating copper plating nickel → → → chrome → cleaning → hot water immersion → Hanging → test → finished product. Production environment and products: Our workshop more concentrated workshop ventilation equipment, work points
