摘要
利用常压介质阻挡放电(DBD)设备,研究了工作气体、放电电压、处理时间、试样布置方式等对聚丙烯(PP)熔喷非织造布吸水率和处理效果均匀性的影响。结果表明:PP非织造布试样在90kV下用氩等离子体处理40s,吸水率达672%,在氩气中混入少量氧气(Ar/O2体积比为10/1),吸水率可提高至717%;试样吸水率随处理时间及放电电压的增加均提高,可以通过增大放电电压来有效地降低处理时间;随着DBD等离子体处理强度的增加,PP非织造布整体亲水性和表观均匀性均得到有效提高;试样布满放电区域有利于提高其吸水率和处理效果的均匀性。
Atmospheric pressure dielectric barrier discharge （DBD） plasma was used to modify melt-blown polypropylene （PP） non-woven fabric to investigate the influence of gas type, discharge voltage, treating time and sample arrangement mode on the water absorption and treatment uniformity. The result showed that the water absorption of PP non-woven fabric could achieve 672% after 40-second argon plasma treatment at 90 kV and could be increased to 717% when a small amount of oxygen was added into argon at the Ar/O2 volume ratio of 10 ： 1. The water absorption was increased with the increase of treating time and discharge voltage. The treating time can be efficiently decreased by increasing the discharge voltage. The hydrophilicity and apparent uniformity of PP non-woven fabric was efficiently improved while increasing the DBD plasma treatment intensity. Arranging the samples all over the discharge zone helped to improve the water absorption and treatment uniformity of the samples.
