近年来,国外对聚氯乙烯粉尘引起的职业危害进行了一些研究但国内尚未见报道。本文对接触聚氯乙烯塑料粉尘的作业进行了调查并做了动物染尘实验研究。现将结果报告如下。 一、生产现场的卫生学调查 我们调查了丹东××厂防腐塑料车间,主要的生产原料是成品的聚氯乙烯塑料板块,其主要成份96％为聚氯乙烯,另外还有少量的增塑剂,稳定剂,色素等。生产工艺是先将塑料原材料进行切割、整形和研磨,再按
In recent years, some foreign occupational hazards caused by PVC dust have been studied but no reports have been reported in China. In this paper, the operation of contact with PVC plastic dust was investigated and experiments on animal dust were done. The results reported below. First, the production site hygiene survey We investigated the Dandong × × Factory anti-corrosion plastic workshop, the main raw material for the production of finished PVC plastic plates, the main components of 96% of polyvinyl chloride, in addition to a small amount of plasticizer , Stabilizers, pigments and the like. Production process is the first plastic raw materials for cutting, shaping and grinding, and then press
