摘要
以白刚玉试验粉尘替代滑石粉 ,并对传统的测尘装置进行了改进 ,较好地解决了对呼吸性粉尘阻尘效率的检验。研制出一种新型高效低阻聚丙烯滤料和新型防尘口罩 ,口罩主要性能参数均达到国家标准。
In this paper,talc powder is substituted for α -Al 2O 3 experimental dust and the dustproof efficiency is tested by improving the traditional dust measuring equipment.The development of a new type of propylene filter material and a new type of dustpro of mask with high efficiency and low resistance are described.The main performance parameters of the mask are all up to national standard.
