防尘呼吸护具在实际中能否被人乐意接受,这有赖于护具的阻力大小、结构尺寸、是否妨碍窥视等。本文简介西德防尘呼吸护具的发展及现状。一、海棉防尘口罩海棉防尘口罩是老矿工所熟悉的防尘呼吸护具。但是,由于这种口罩的过滤能力很差而影响其销售。现在,西德矿业职业协会号召所有的矿业不再应用这种海棉口罩。后来,针对以上本质问题进行改进,即提高过滤效率和降低呼吸阻力,同时还注意
Whether the dust-breathing breathing apparatus can be accepted by people in reality depends on the resistance of the protective device, the size of the structure, whether it impedes the sighting and the like. This article describes the development and status quo of the West Germany dust protection gear. First, the sponge dust mask sponge dust masks are familiar mine dust respirator. However, due to the poor filtering capability of such masks, their sales are affected. Now, the West German Mining Association calls on all mining no longer apply this sponge mask. Later, in view of the above essential problems to be improved, that is, to improve the filtration efficiency and reduce respiratory resistance, but also pay attention to
