Abstract

The invention discloses a brightening metal-stripping solution. The stripping solution per liter comprises the following components at mass concentration: 150-170 g / L ammonium nitrate, 60-75 g / L sodium acetate, 30-35 g / L thiourea, 20-25 g / L inositol hexaphosphate, 10-30 g / L polyoxyethylene, 5-9 g / L sodium diethylhexyl sulfosuccinate, 4-8 g / L urotropine, 2-4 g / L ammonium thiocyanate, 0.2-2 g / L imidazoline and 0.05-0.1 g / L sodium dodecyl sulfate. The brightening metal-stripping solution is complete in stripping, can completely remove a surface coating, has a brightening effect on the base metal material and enables the metal surface to be compact, thereby laying a favorable foundation for re-electroplating.

Description

Technical field [0001] The present invention involves a metal recession. Background technique [0002] The so -called degraded liquid, as the name implies, is a layer of special metal or metal substance plating on the surface of the workpiece on the surface of the workpiece to effectively remove it by soaking, heating, ultrasonic, electrolytic, etc.Corrosion and non -changing chemical liquid; in this sense, there are many types of retreating liquids. At present, the state or industry does not make a clear classification method and scope of the regulating solution.Institutions and production enterprises, according to the substrate of the degraded workpiece, the scope of the plating liquid is given to it, such as: metal recession and non -metal recession. [0003] At present, the existing degraded plating fluid is incomplete, and the substrate material after the decoction is rough and dumb. If you need to do a lot of pre -processing work before electroplating, it does not have real...
