The surface treatment processes of Stainless steel paint letters mainly include the following:
Sandblasting: Sandblasting is a very common surface treatment process in the production of Stainless steel paint letters. It uses the driving force obtained by the development and contraction of gas to spray the spray material uniformly onto the stainless steel surface at high speed, causing physical changes to the stainless steel surface, such as becoming rough, increasing adhesion, etc. Sandblasting is often used to improve the adhesion of stainless steel surfaces, making it easier for baking paint to adhere, and can improve the quality of machined surfaces, such as removing burrs, decontamination, etc.
Chemical treatment: Chemical treatment is to treat the surface of stainless steel with chemicals to change the chemical properties of its surface, such as increasing the corrosion resistance and wear resistance of the surface. Common chemical treatment methods include electroplating, chromate treatment, polyphosphate treatment, etc. These treatments can form a protective film on the stainless steel surface, thereby improving its corrosion resistance.
Wire drawing treatment: Wire drawing treatment is a surface treatment process that forms lines on the surface of stainless steel through grinding. This treatment process can give the stainless steel surface a non-mirror-like metallic luster and eliminate minor surface imperfections. Brushed textures are divided into straight textures, random textures, corrugated textures, dazzling textures, etc., which can be selected according to needs.
Polishing treatment: Polishing treatment is to modify the surface of stainless steel by using polishing tools and abrasives to obtain a smooth surface or mirror luster. Polishing treatment is divided into three processes: coarse polishing, medium polishing and fine polishing. You can choose the appropriate polishing wheel according to your needs to achieve the best effect. Polishing not only improves the aesthetics of the stainless steel surface, it also removes the shine.
Baking paint treatment: Baking paint treatment is to spray one or more layers of paint on the stainless steel surface and bake it at high temperature to solidify the paint layer. This treatment process can give the stainless steel surface rich color, luster and texture, and enhance its corrosion resistance. The key to baking paint treatment is to select the appropriate baking paint material and control the baking temperature and time.
These surface treatment processes can be combined as needed to obtain the best Stainless steel paint letters.
