聚酯薄膜的电晕处理及其应用

Corona discharge treatment of polyester film and its appliance

讨论了聚酯薄膜电晕处理及其应用的关系，指出在一些应用范围电晕处理的必要性。简介了电晕处理的原理、工艺和要求，表明：为提高聚酯薄膜的印刷、粘合和真空镀金属（铝等）的效果，表面张力应达到52mN／m以上，且贮存2年内仍然保持不变。

The refation between corona discharge theatment of polyester film and its appliance were discussed.It was indicated that the corona discharge treatment was necessary in some applied field of polyester film.The theory, technique and requirment of corona discharge treatment was introduced simply. It was shown thatsurface tension of polyester film needed higher than 52 mN／m for print,bond and metallization,and that 52mN／m of surface tension is held after storage for two years.
