印刷行业与工业上最常见的有毒物质——铅是分不开的。如果在生产上不注意,长期接触金属铅或是铅的化合物(如氧化铅、铅丹、铅白、硫酸铅、硝酸铅等)就可引起铅吸收或是铅中毒,所以说,搞好予防工作是工厂企业保健医务工作者的重要职责之一。现结合我厂开展予防铅中毒工作的情况作一简略介绍: 生产工艺过程是以铅(占75％)、锑(14—15％)、锡(5—7％)合金作原料,分熔铅、铸字、排板、印刷、装订等工序。其中熔铅、铸字、铸版工序中铅加热温度达400—600℃以上,因而有
The most common toxic substance in the printing industry and industry - lead is inseparable. If production is not noticed, long-term exposure to metallic lead or lead compounds (such as lead oxide, lead oxide, lead white, lead sulfate, lead nitrate, etc.) can cause lead absorption or lead poisoning, Work is one of the important responsibilities of factory health care workers. Now combined with our factory to prevent lead poisoning for a brief introduction: The production process is based on lead (75%), antimony (14-15%), tin (5-7%) alloy as raw material, melting lead , Cast word, row plate, printing, binding and other processes. Including lead-melting, casting, casting process of lead in the heating temperature up to 400-600 ℃, so there
