1 paint-plated insulation method.
For example, plastics such as polyvinyl chloride are difficult to activate and electroplating, so you can use a layer of easy-to-activate and electroplated paint on the surface of plastic parts that need to be electroplated, such as ABS paint and epoxy resin-based paint, and then, according to the pretreatment process of paint type, the plastic plating parts can be activated and electroplated so that the coating can only be deposited on the surface of the paint, so as to achieve the purpose of local electroplating of plastic plating parts. The unpainted surface is insulated by itself.
2 coating and anti-paint insulation method.
This insulation method is contrary to the use of platable paint, which is difficult to activate and electroplated paint is applied to the insulated parts of easy-to-activate and electroplated plastic parts, such as acrylic paint, etc. and then carry on the activation of the pretreatment process of the matrix plastic and electroplating. In this way, the insulation parts can achieve the purpose of non-coating deposition, thus realizing the local electroplating of plastic plating parts.
3 insulating method with poisonous paint.
The so-called poisonous paint refers to the combination of about 10% sulfide added to the ordinary insulating paint. When in use, the poisonous paint is evenly applied to the insulation parts of the plastic plating parts, and when the activation and electroless plating operation of the parts are carried out, depending on the catalytic toxicity of the toxic paint, the electroless plating reaction process can not take place in these coating parts, so as to achieve the purpose of local plating of plastic plating parts.
Before the local electroplating, the non-electroplated parts need to be insulated. However, because the insulation process requirements are very strict, the insulation plating process requirements must be strictly observed in the insulation operation to ensure the beauty and safety of the electroplating parts.
