一种新型ePTFE覆膜滤料的实验研究

摘要

介绍了一种新开发的ePTFE覆膜滤料过滤阻力与分级除尘效率的实验测定结果。在过滤风速为0.5~2.5 m/s时，该覆膜滤料洁净滤料的阻力为27~171 Pa；在过滤风速为1.2 m/min，其对PM2.5颗粒的净化效率达98%以上。%Introduces the test results of filtering pressure drop and fractional filtering efficiency on a new kind of ePTFE membrane filter. Under the test wind speed is between 0. 5~2. 5 m/s,the pres-sure drop of this clean membrane filter is about 27~171 Pa;Under the test wind speed is at 1.2 m/min,its collection efficiency is more than 98%for PM2. 5.
