Due to the high humidity and sometimes corrosive impurities in the materials dried by the sand dryer, the equipment may experience corrosion and rusting during operation. Once the sand dryer corrodes and rusts, it will lead to a decrease in the performance of the sand dryer and shorten its service life. So, how should a sand dryer prevent corrosion and rust? The following are good methods summarized by Sinonine based on years of experience in using sand dryers.
1.Using passivation and phosphating methods to treat sand dryers can not only make the surface of rusted steel workpieces appear metallic, but also generate a dense anti rust film layer on the metal surface. In this way, even if the sand dryer is in a humid environment, it will not rust, and this method is easy to operate, which can greatly save manpower and material investment. It is currently a widely used anti-corrosion and rust prevention method.
2.The cylinder of the sand dryer is made of stainless steel material. In general, with the extension of drying time, ordinary carbon steel dryers are prone to corrosion and rust in long-term humid environments, while stainless steel cylinders have excellent corrosion resistance.
3.Spray electrostatic powder. The so-called spraying electrostatic powder refers to spraying a new type of coating on the cylinder of a sand dryer, which has toughness, durability, strong weather resistance, high heat resistance, and excellent appearance performance.
4.Take good care of the protection work at the welding point. There are many parts on the cylinder of the sand dryer that must be welded, and if the welding parts corrode, it will seriously affect the service life of the equipment. So, when welding the sand dryer, stainless steel material can be used for welding to enhance the dryer's corrosion and fracture resistance.
