The powder coating equipment in production has to deal with mud and water every day. In addition, the ingredients of some ingredients are highly corrosive, which can easily cause rust spots on the equipment. Below we will introduce several anti-rust methods.
1. Put sulfides into neutral salts, carbonates, reducing salts and other inorganic substances, and under the action of a temperature below 600 °C, the sulfur in the free state is decomposed and diffused to form a sulfide on the surface of the complete set of paint equipment. material layer, which improves the wear resistance of the part.
2. This is a method of quenching and hardening only the heated surface layer through the skin effect and proximity effect of high-frequency current by placing the complete set of coating equipment in the high-frequency coil, which can be used to increase the damage resistance.
3. Use an oxygen-acetylene flame to quickly heat the surface layer of the coating equipment to the quenching temperature, and then quench, and the surface will transform and harden.
