玻璃镀银是普通物理实验技术之一。有一些参考书上对镀银溶液的配方和简单的工艺过程都作了介绍。但是按照书本上的方法使玻璃镀银,常会出现下列问题:(1)反射面上容易有黑疵、影子、白皮;(2)银层不够细腻均匀;(3)放置时间过久则变黄、脫落。带着这些问题,我们到工厂参观学习,获益很大。现把镀银工艺和我们的实践体会介绍如下。
Glass silver plating is one of the common physical experiment techniques. There are some reference books on the silver plating solution and a simple process are introduced. However, in accordance with the method of books to silver glass silver, often the following problems: (1) reflective surface prone to black defects, shadow, white skin; (2) silver layer is not delicate and uniform; (3) Yellow, fall off. With these questions, we visited the factory to learn, great benefit. Now the silver plating process and our practice experience described below.
