清砂是铸造车间不可缺少的工艺之一,清砂过程往往产生高游离二氧化硅含量的粉尘,严重危害工人的身体健康。近年来,国内不少厂家虽采用振动、水爆等多种不同的清砂方式以取代手工清砂,但防尘效果不令人满意。某机床厂安装了一套QAJ吊链辊道联合抛丸清理室设奋,经卫生学评价效果显著。 Sand cleaning is one of the indispensable processes in the foundry. The sand removal process often produces dust with high free silica content, seriously damaging the health of workers. In recent years, although many domestic manufacturers use vibration, water blast and other different sand-cleaning methods to replace manual sand cleaning, but the dust-proof effect is not satisfactory. A machine tool plant installed a set of QAJ hanging chain roller joint blasting cleaning room Fen, by the health evaluation of significant results.
