纯铜门，覆铜门，镀铜门的工艺流程：
Process flow of pure copper door, copper clad door and copper plated door:
经过着色的铜门，由于更具有美感，且其使用、观赏价值比较高，因而受到人们的普遍欢迎。着色铜除有美丽的外观，作为装饰外，还可以提高铜的耐磨性和耐蚀性，因此，着色技术开发了表面处理又一新领域。
Colored copper doors are generally welcomed by people because they are more aesthetic and have high use and viewing value. Colored copper not only has beautiful appearance as decoration, but also can improve the wear resistance and corrosion resistance of copper. Therefore, coloring technology has developed another new field of surface treatment.
1、处理工艺：除油除锈除氧化皮——水洗——酸洗抛光——水洗——中和——水洗——着色处理——水洗——干燥及其它后处理
1. Treatment process: degreasing, derusting and scale removal - water washing - pickling and polishing - water washing - neutralization - water washing - coloring treatment - water washing - drying and other post-treatment
2、酸洗抛光推荐使用铜材酸洗橡胶托辊 槽型托辊 皮带托辊 平行托辊 保定搬家 保定搬家电话 保定搬家公司 保定搬家 铜鼎 铜狮子 抛光液进行处理。目的是使黄铜表面具有光泽。
2. It is recommended to use copper pickling and polishing solution for pickling and polishing. The purpose is to make the brass surface shiny.
3、将工件浸泡于工作液中，黄铜表面即变成黑青色，根据实验结果。工件可重复浸泡，增加变色层厚度，可获得满意效果。
3. When the workpiece is immersed in the working fluid, the brass surface turns black and cyan. According to the experimental results. The workpiece can be soaked repeatedly to increase the thickness of discoloration layer, and satisfactory results can be obtained.
4、如想达到古铜色，经上述步骤处理后，可用砂纸摩擦，方可达到理想的效果。
4. If you want to achieve the bronze color, after the above steps, you can rub with sandpaper to achieve the ideal effect.
