The difference between powder spraying and liquid spraying of aluminum profiles

The spraying process of aluminum profiles is mainly divided into two methods: powder spraying and liquid spraying. Powder spraying adopts the principle of electrostatic adsorption to spray powder coating on the surface of aluminum profiles, and then forms a coating through high temperature curing. Powder spraying has the advantages of environmental protection, high efficiency, and uniform coating thickness. Liquid spraying is to spray liquid coating evenly on aluminum profiles through a spray gun, and then naturally dry or cure at low temperature. Liquid spraying has more diverse color options and can achieve complex patterns and effects. Both have their own advantages and disadvantages, and the specific choice depends on the application occasions and performance requirements of the product.
