摘要
通过对8种常用类型防霾口罩的实验测试,采用回归曲线分析方法得出了防霾口罩呼吸阻力随使用时间的变化函数形式,同时也通过实验数据统计给出了各种类型口罩的建议使用时长,建议N90和N95无纺布防霾口罩在空气轻度污染下使用时长不超过11~12 h,中度污染下不超过8~10 h;而棉布为面料的N95口罩在轻度污染下使用时长不超过7 h,中度污染下不超过6 h。
Based on the experimental tests for 8 types of commonly used anti- dusk masks,the anti- dust mask respiratory resistance function form with the change of time is obtained through the regression curve analysis method,and at the same time the experiment data statistics shows the recommended duration of use of the various types of masks. It suggests that non- woven masks N90 and N95 is used not more than 11 ~ 12 hours under mild air pollution and 8 ~ 10 hours under moderate pollution; respirator use time of cotton fabrics N95 doesn＇t exeed 7 hours under light pollution and 6 hours under moderate pollution.
