What work should be done before galvanized hot wire

Electroplating pretreatment is the basis of electroplating and the key to ensure the quality of hot plating wire. If the substrate is not treated to the specified requirements before electroplating, even with good electroplating solution, appropriate electroplating parameters and equipment for regulating electroplating parameters, as well as highly skilled personnel, it is impossible to obtain the electroplating coating meeting the quality requirements.

Before plating is not only to remove metal matrix, and the existence of oils and affect coating adhesion and other quality requirements of foreign substance, also want to remove the surface oxide, make its have the specified cleanliness and surface activity, to ensure that the coating and the substrate firmly with, according to the requirements of the appearance of the plating, sometimes will make some other special treatment before plating.

The service condition and service life of electrogalvanized metal or components are closely related to the plating thickness. The more stringent the use conditions and the longer the service life, the thicker the required galvanizing layer should be. Different products, according to the specific environment (temperature, humidity, rainfall, atmospheric composition, etc.) to determine the expected service life of the electroplating thickness, blind thickening will cause a variety of waste. But if the thickness is insufficient, it will not meet the expected service life requirements.

Different manufacturers, according to their own equipment conditions, in the case of determining the plating type, first compile a more complete and reasonable process flow, clear plating parameters, control plating solution concentration, standard operation. Post-plating treatment for the purpose of enhancing protection, decoration and other special purposes of plating parts. After galvanizing, chromate passivation, or other conversion treatment is generally required to form the corresponding type of conversion film, which is one of the key processes to ensure the quality of the plating.
