聚四氟乙烯具有良好的耐磨、耐化学腐蚀、耐压和耐热等性能,自1941年开始应用,应用范围逐年扩大。聚四氟乙烯的热解产物羰基氟化物是以无机氟离子形式代谢排出,故以尿氟作为研究聚四氟乙烯中毒的一个指标。本文调查了一个制造聚四氟乙烯部件的小厂。该厂的工艺可分为成型和机械加工两个主要车间。成型车间有九个烧结炉(321°～376℃),根据以前调查证明这个地方是引起聚合物烟雾热病的主要地方。机械加工车间没有加热聚四氟乙烯的操作过程。工人在工厂随意吸烟。这次调查包括
PTFE has good wear resistance, chemical resistance, pressure and heat resistance and other properties, application since 1941, the scope of application has expanded each year. Polytetrafluoroethylene pyrolysis products carbonyl fluoride is the form of inorganic fluoride ion metabolism, so urine fluorine as an indicator of polytetrafluoroethylene poisoning. This article investigates a small factory that makes polytetrafluoroethylene parts. The plant’s process can be divided into two major workshops forming and machining. There are nine sintering furnaces (321 ° ~ 376 ° C) in the molding shop. According to previous surveys, this place has proved to be the main place where polymer smoke fever is caused. Mechanical processing workshop is not heated Teflon operation. Workers smoke freely in the factory. This survey includes
