The R&D team of Guangdong Bigely Technology has developed a high-quality and environmentally friendly cyanide-free alkaline zinc additive BZ-518. Here are the characteristics:
The reason for using hydrochloric acid for plating rust removal is that hydrochloric acid is effective in removing oxidized layers, rust, and other contaminants from metal surfaces. Metal surfaces can easily form a layer of iron oxide, or rust, after prolonged exposure to air. These oxides must be thoroughly cleaned before plating to ensure that the plating layer adheres evenly and firmly to the metal surface.
High phosphorus electroless nickel plating is a high-speed, environmentally friendly, high phosphorus (10.5 to 12%) semi-bright plating, which is suitable for electroless nickel plating on aluminum alloys, stainless steel, carbon steel, alloy steel, copper alloys, and some non-conductive substrates.
In the plating industry, nickel-plated workpieces on copper often face many challenges if they need to be unplated and reworked. Conventional depalletizing methods are not only inefficient, but may also cause damage to the copper material, affecting the quality of subsequent processing. To solve this challenge, Bigely Technology has introduced nickel removal agent BT-3.
During aluminum machining, the surface of aluminum alloy parts is often contaminated with various oils, residual polishing paste, hand prints, oil seals, surface waxes and other contaminants. In order to ensure the quality of subsequent plating or oxidation treatment, the degreasing of the aluminum surface is crucial. However, aluminum has poor chemical stability and is prone to corrosion in alkaline or acidic environments. How to avoid corrosion of the substrate while removing oil has become a major challenge in the development of aluminum degreasing powders.
Zincate zinc plating is a zinc plating process using zinc oxide as the main salt and sodium hydroxide as the complexing agent, and the process requires a zincate zinc plating brightener to obtain a zinc plating layer with detailed crystallization and high brightness over a wide working range.
