摘要
在室外环境空气中,利用2台同型号PM2.5自动监测设备,对市面上常见的5类口罩进行全天候的同步模拟比对试验,比较各类口罩对PM2.5的防护效果。模拟试验结果表明,不是所有的口罩对PM2.5都有防护作用,试验选择的5类口罩中,有防尘特殊要求的N95和N90口罩防护效果较好。
In this paper, 5 masks＇blocking effects against PMz.5 were synchronously tested. The test used 2 sets of PM2.s automatic monitoring equipments of same model and went on under actual ambi- ent air conditions for a whole day. The results showed that not all masks had protective effect for PM2.5, and in blocking PM2.5, N95 and N90, which were designed for special dust -proof, were su- perior among 5 tested masks.
