一、前言将塑料表面赋予金属化,不但能以塑料代替金属,使产品达到轻便而电气性能良好的目的,而且可以使塑料富有金属感和装饰性,因而受到人们的普遍欢迎。塑料表面金属化技术按工艺方法的不同,可分为干法和湿法两大类。湿法如塑料电镀,干法如真空镀膜。真空镀膜法技术是近年高速发展起来的一门新技术,由于它具有工艺简 First, the introduction of the plastic surface to give the metal, not only to plastic instead of metal, the product is light and electrical properties to achieve a good purpose, but also to make the metal rich metal and decorative, which is generally welcomed by people. Plastic surface metallization technology according to the different methods can be divided into two categories of dry and wet methods. Wet method such as plastic plating, dry method such as vacuum coating. Vacuum coating technology is developed in recent years, a new high-speed technology, because it has a simple process
