摘要
采用直流辉光放电产生的冷等离子体对塑料表面进行处理，研究了接触角、粘接力在处理前后的变化，结果表明ＨＤＰＥ 薄膜的接触角由原８４°降低到３０°，ＰＰ 膜由原８８°降低到３８°，粘接力相应提高到３０ 倍，较佳的处理条件为电流密度２ ～５ ｍ Ａ／ｃｍ ２ ，处理时间２ ～１２ ｍｉｎ ，本底气压３０ ～２００Ｐａ ，工作气体可选用空气或氧气。对所研制的表面处理机作了简单介绍。
s The surface of plastics products was treated by cold plasma produced by DC glow discharge.The changes of contact angle and adhesive force before and after the treatment were studied.The resuls showed the contact angle of HDPE film decreased from 84° to 30°,that of PP decreased from 88° to 38°,and the adhesive force increased 30 times.The optimum conditions for the treatment were as follows:current density 2～5 mA/cm 2,time 2～12 min,basic atmospheric pressure 30～200 Pa,and the working gas may be air or O 2.A brief introduction to the prepared treater was also given in this paper.
