实践证明,低铬酸镀铬是一项值得推广的新工艺。但是,目前也存在一些需要深入探讨的问题。下面结合两年多的生产实践,谈一下我们的体会。一、溶液组成低铬酸镀铬有许多种不同成份的镀液。这些镀液中除了含有铬酐之外,必须 Practice has proved that low chromium chromate is a worthy promotion of new technology. However, there are still some issues that need to be further explored. The following combination of more than two years of production practice, talk about our experience. First, the solution composition Low chromate chrome plating There are many different components of the bath. These baths must contain, in addition to chromic anhydride
