为了满足社会生活和生产需要,近年来,对非金属趋向采用表面金属化处理,特别是仿金色的装饰技术发展较快。真空镀膜仿金工艺,具有工艺简单,操作方便,易于控制,返工容易,生产效率高,成本低,无污染,占地少,对材质的适宜性强,产品外观装饰性好等优点。与电镀相比,它具有一定的竞争能力,其发展前景广阔。一、前处理表面前处理的优劣是决定非金属真空镀膜成败的关键,前处理方法按材质不同而异。前处理工序主要是化学侵蚀(或机械粗化)和浸底漆。
In order to meet the needs of social life and production, in recent years, the nonmetal tends to adopt the surface metallization process, especially the imitation gold decoration technology develops rapidly. The vacuum coating imitation gold process has the advantages of simple process, convenient operation, easy control, easy rework, high production efficiency, low cost, no pollution, small occupation, strong suitability to materials and good decorative appearance of products. Compared with electroplating, it has a certain competitive ability, its development prospects. First, the pre-treatment surface The pros and cons of the pre-treatment is to determine the key to the success of non-metallic vacuum coating, pre-treatment methods vary by material. Pre-treatment process is mainly chemical erosion (or mechanical coarsening) and priming.
