聚丙烯熔喷驻极过滤材料表面静电势的研究

将未经过驻极处理的聚丙烯熔喷过滤材料进行电晕驻极处理,通过测定聚丙烯熔喷驻极滤料的过滤效率和表面静电势,分析滤料表面正负电荷的分布以及表面静电势与滤料过滤效率的关系.结果表明:滤料表面的静电势呈现随机的正负分布,并且随着滤料表面平均静电势的提高,滤料的过滤效率提高.

Study on the Surface Electrostatic Potential of Electret Melt-blow Material

The melt-blown material were processed with external corona electret,then test the filtration efficiency and the surface electrostatic potential,Analyzed the 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 that charge distribute at random and the average surface electrostatic potential raises,the filtering m...
