我厂有一台外圆磨床,因铁屑等机械杂质进入床身导轨,造成床身导轨与工作台导轨严重拉毛,面积达2％～3％,深度达0.6～0.8mm。我们采用了先进行化学镀铜,后用锡鉍合金钎焊的办法修复。现简述如下:一、化学镀铜工艺1号镀铜液的配方:浓盐酸(化学纯)30％;锌(纯)和硫酸铜各占4％:蒸馏水62％。配制方法:先按重量比将上述成份分别秤好后,把锌加入浓盐酸中。待锌全部溶解后,加入硫酸铜,用玻璃棒搅拌均匀。再把蒸馏水加入,搅匀后即可使用。2号镀铜液的配方:硫酸铜50～60％,蒸馏水40
I plant a cylindrical grinding machine, due to iron filings and other mechanical impurities into the bed rails, resulting in serious bed rails and table rails Maozhi, an area of 2% to 3%, a depth of 0.6 ~ 0.8mm. We use the first chemical plating of copper, after using tin-bismuth alloy brazing repair. Now summarized as follows: First, electroless copper plating process No. 1 copper plating solution formula: concentrated hydrochloric acid (chemical pure) 30%; zinc (pure) and copper sulfate each 4%: 62% distilled water. Preparation method: first weight ratio of the above ingredients were weighed, the zinc was added to the concentrated hydrochloric acid. After the zinc is completely dissolved, copper sulfate is added and stirred with a glass rod. Then add distilled water, stir well to use. 2 copper plating solution: copper sulfate 50 ~ 60%, 40 distilled water
