[目的]为评价覆盖剂控制熔铅炉蒸气弥散效果。[方法]对通州市钢丝绳厂使用覆盖剂控制熔铅炉铅蒸气弥散效果进行了初步观察。[结果]覆盖剂控制车间内铅烟(蒸气)浓度有一定效果,未使用覆盖剂时,车间内铅烟浓度范围为0.370～0.975mg/m~3,样本超标率达100％。使用覆盖剂后,车间铅烟浓度范围为0.005～0.631mg/m~3,样本超标率为50％。[结论]该覆盖剂对控制熔炉车间内铅烟浓度有一定效果。
[Objective] To evaluate the effect of coating agent on the vapor diffusion of molten lead furnace. [Method] Preliminary investigation was made on the control effect of lead vapor diffusion in lead-melting furnace by using coating agent in Tongzhou Wire Rope Factory. [Result] The covering agent could control the concentration of lead (steam) in the workshop to a certain extent. When the covering agent was not used, the concentration of lead in the workshop ranged from 0.370 to 0.975 mg / m ~ 3. After using the coating agent, the concentration of lead in the workshop ranged from 0.005 to 0.631 mg / m ~ 3, and the sample exceeded the standard rate of 50%. [Conclusion] This coating agent has a certain effect on controlling the concentration of lead in furnace.
