摘要:

采用电晕充电法制备了聚丙烯纤维驻极体滤材。考察了充电电压、充电时间、充电距离、环境湿度等因素对驻极体滤材储电性能的影响,通过正交试验设计,分析了各因素的影响程度。结果表明,用电晕充电法使聚丙烯纤维滤材形成驻极体是切实可行的,表面电位随充电电压、充电时间的增加而增加,而随充电距离和环境湿度的增加而减小,表面电位的保留率随环境湿度的增加而减小。充电电压对表面电位的影响非常显著,环境湿度影响次之,充电时间和充电距离的影响最小。最佳工艺条件为:充电时间30min、充电距离8mm、充电电压10kV、环境湿度35%。

Abstract:

The electret filters made of polypropylene(PP) fiber were prepared by means of corona charging method. The effects of charging voltage, charging time, distance between electrodes as well as ambient humidity on the charge storage properties of PP fiber electret filter were evaluated, and the contributory degree of each factor was analyzed by orthogonal test. The results show that it is feasible to prepare PP fiber electret filter by using such corona charging method. The surface voltage increases with the charging voltage and charging time, but decreases with the ambient humidity and distance between electrodes. Retention ratio of surface voltage decreases with the increase of ambient humidity. Charging voltage has the significant influence on surface voltage, followed by the ambient humidity, Charging time and distance between electrodes have the least effect. The optimum conditions are charging time of 30 min, distance between electrodes of 8mm; charging voltage of 10kV, and ambient humidity of 35%.
