2、 Electret Melt-blow MaterialZHOU Chen, JIN Xiang-yu（ The Development Centre of Industrial Non-woven Material , Shanghai 201620, China)Abstract The melt-blown material were processed with external corona electret, then test the filtration efficiency and the surface electrostatic potential, Analyzed t
3、he distribution of positive and negative charge of the surface and the relationship between average surface electrostatic potential and filtration efficiency by measuring the surface electrostatic potential of electret melt-blow martial. The results show thatcharge distribute at random and the average surface electrostatic potential raises, the filtering medium has a better filtration efficiency performance.Key words： electret； filter material； surface electrostatic potential欢 迎 订 阅欢 迎 来 稿欢 迎 刊 登 广 告!“!“!“!“19
