It is necessary in engineering and there are many ways to carry out it,among which cyanide electroplating is widely used.Although it is more harmful,this method has advantages and is still widely used in industry.

　　Advantages of cyanide electroplating:

　　1.The potassium cyanide manufacturer introduced that the plating solution of this electroplating process has a certain ability to remove oil and activate.Cyanide has strong chelating ability and high cathodic polarization of the tank solution,so it has excellent plating and covering ability,and can be coated with copper layers with good adhesion on various metal substrates.

　　2.Various impurities have less impact on the plating solution,and the process specification requirements are broad,easy to control,and can basically adapt to the electroplating requirements of various complex shaped parts.The coating obtained from cyanide copper has a bright surface,fine crystallization,and low porosity.Easy to polish,with good conductivity and weldability.

　　3.Cyanide electroplating is a crucial step in the entire electroplating process,therefore,the on-site control level of an electroplating technician determines the electroplating quality of the product.

　　From the perspective of factory production,cyanide is irreplaceable in electroplating due to its low cost and wide operational range.The higher the concentration of the plating solution,the greater the loss,and unfortunately,cyanide has a wide working range and can be used at extremely low concentrations.That is to say,the electroplating solution can be used in a more relaxed environment,which is very practical for many small electroplating factories that do not have many testing conditions.
