一、喷砂室通风除尘中存在的问题喷砂是常用的工艺方法之一。由于喷吹材料中含有SiO_2,为避免SiO_2及粉尘危害人体和污染环境。必须搞好喷砂室的通风与除尘。目前喷砂室设备的结构及通风设计,基本是沿袭一套旧的作法,使用中暴露出一些问题。主要有: 1.喷砂室内能见度差。工人不得不经常地通过袖口把零件拿出来观察,这不仅影 I. Problems in Ventilation and Dust Collection in Sandblasting Chambers Sandblasting is one of the commonly used process methods. Since the blowing material contains SiO 2 , in order to avoid SiO 2 and dust damage the human body and pollute the environment. Must do a good job in blasting room ventilation and dust removal. At present, the structure and ventilation design of the blasting chamber equipment basically follows an old set of practices, and some problems are exposed during use. Mainly: 1. Bad visibility in sandblasting room. Workers often have to look out parts through the cuffs, not only
