If the aluminum polishing wax is not handled well, resulting in poor quality of electroplating products, and customers want to complain, what should you do? Today's article will teach you how to do a good job of wax removal.

How is the polishing wax created?

Aluminum has excellent physical and chemical properties and surface treatment properties and is widely used in precision hardware, 3C electronic products, automobile auto parts, handicrafts and other industries. The use of polishing wax to improve the comprehensive performance of aluminum products, surface finish and decorative effect is the surface treatment industry commonly used technical means.

The surface, pores and depression of the aluminum products polished by polishing wax will have wax and dirt attached to the workpiece by mechanical adsorption, intermolecular adsorption and electrostatic adsorption, etc. It is necessary to remove wax in time, otherwise it will lead to problems such as plating peeling, uneven coloring, spraying and paint removal of aluminum products.

How to remove wax

Dewaxing is the first process of surface pretreatment such as electroplating, anodizing, spraying, etc. Whether the dewaxing is effective and thorough is of vital importance. Choosing a good wax removal method can improve the performance of wax removal, optimize product quality and bring good economic benefits.

Currently organic solvent method, chemical method, electrochemical method and water-based cleaning agent method are the four main types of metal dewaxing methods.

Organic solvent method can not effectively remove the polishing wax on the metal oxides, carbides and other abrasive materials, while chemical, electrochemical method exists using strong acid or alkali as cleaning materials, easy to cause corrosion of aluminum.

De-waxing water is a water-based de-waxing cleaning agent, which can overcome the shortcomings of organic solvent method, chemical method and electrochemical method of de-waxing.

Up to now, there are many kinds of aluminum wax removers in the market, but most of them have the problems of unsatisfactory wax removing effect and slight corrosion to aluminum products. For this reason, Bigely has developed a non-corrosive, long-life aluminum wax remover BC-1, which can solve the above mentioned problems.
