What cleaning needs to be done before galvanized wire plating

Compared with other galvanizing processes, galvanized iron wire requires a low standard for pre-plating cleaning of the substrate during cyanide galvanizing. However, in the current trend of increasing the quality grade of cyanide galvanized layer, some pollutants are introduced into the plating tank. Obviously become harmful. Since cleaning the galvanized layer wastes a lot of time and reduces the yield, it is very important to properly clean the substrate and perform an effective rinsing operation before plating.

Defects such as surface layer removal, surface inclusions, etc., which are widely removed from the exterior of the deposited layer, can be found and treated by conventional techniques; excess foam is formed by the incorporation of soap and saponifiable fatty surfactant into the bath. Moderate foam formation rates may be harmless. The large amount of tiny homogenous particles present in the bath stabilizes the foam layer, but the accumulation of excessive solid particles can cause an explosion. Use activated carbon to remove surface active substances. Or the foam is not stable by filtration, which is an effective measure;we are galvanized wire suppliers and provide galvanized iron wire,you can know it.

 other measures should be taken to minimize the amount of surfactant introduced. The introduction of organic matter can significantly reduce the plating speed. Although the chemical formulation is advantageous for high deposition speeds, the thickness of the coating cannot be satisfied after the organic matter is taken, so that the activated carbon can be used to treat the bath.

The company has strong technical strength, complete product inspection procedures, and has the right to import and export. The products sell well all over the country and are exported to more than 20 countries and regions such as the United States, Germany, Finland, Belgium, Russia, Japan, South Africa, etc., and are favored by customers.
