为了探讨碳化硅(SiC)粉尘对肺的影响,作者观察了267名SiC生产工人。其中141名在观察期间为现职工人,126名为离职工人。SiC的生产原料为石油、焦碳、高纯度晶体硅石和锯屑。当电流通过石墨电极时,使熔炉中的原料在2300℃条件下发生反应,生成SiC其生产过程为原料加工及混和、装炉、焙烘、冷却、熔融、粉碎、过筛等,最后将产品送入仓库保 In order to investigate the effect of silicon carbide (SiC) dust on the lungs, the authors looked at 267 SiC production workers. Of these, 141 were employed and 126 were left-off workers during the observation period. SiC raw materials for the production of petroleum coke, high purity crystalline silica and sawdust. When the current through the graphite electrode, the raw materials in the furnace at 2300 ℃ under the conditions of reaction to generate SiC production process for raw materials processing and mixing, loading furnace, baking, cooling, melting, crushing, sieving and the like, and finally the product Into the warehouse warranty
