珍珠岩(Perlite)是一种新发展的高级轻质材料,具有良好的隔热、绝缘、防潮和吸附性能,除用做建筑材料外,还可做高效除油剂、绝缘体、滤过剂、填充剂和土壤调整剂等。辽宁省内从事珍珠岩开采、加工,先后近四十个单位,约有1万工人。由于多数生产单位为乡镇企业,设备简陋,工艺落后,生产环境粉尘浓度较高,严重影响工人健康,因此,粉尘危害急待解决。
Perlite is a newly developed advanced lightweight material with good thermal insulation, insulation, moisture absorption and adsorption properties. Besides being used as construction material, Perlite can also be used as an effective degreaser, insulator, filter agent, Fillers and soil conditioner. Liaoning Province engaged in perlite mining, processing, has nearly 40 units, about 1 million workers. As the majority of production units are township and village enterprises, the equipment is poor, the technology is backward, and the dust concentration in the production environment is high, seriously affecting the health of workers. Therefore, the dust hazard urgently needs to be solved.
