How to maintainance the dryer and anti rust?
First, the electrostatic powder coating method. The electrostatic powder spray coating method is a new type of powder coating method in the dryer barrel. Many manufacturers use liquid paint spray dryer cylinder of the old-fashioned way, but it contains a lot of liquid paint ester ketones and hydrocarbons and other organic solvents, this solvent is flammable, explosive and very safe. production, construction, transportation, storage, etc. cause a lot of trouble, but usually with a kind of liquid toxic, volatile air, would cause serious environmental pollution. Manufacturing dryer, are usually used in cold-rolled stainless steel, the high cost of steel, he can not be replaced by ordinary carbon steel with superior corrosion resistance. Powder coating electrostatic powder coating method used its corrosion resistance of stainless steel completely comparable, we can use ordinary carbon steel instead of stainless steel. And such powder coatings with a tough, durable, decorative and good, and has excellent outdoor weathering resistance and heat resistance, but also has excellent resistance to industrial dryer corrosion and powder properties, excellent gloss and shade performance, can replace completely the use of stainless steel dryer, greatly reducing costs.
Second, welding austenitic nickel-chromium stainless steel welding. The dryer many parts must be welded, the nostalgic welding materials often fracture, corrosion phenomena. Impact on the life of the dryer and its serious. The difference between the austenitic nickel-chromium stainless steel and carbon steel is a poor thermal conductivity, when heated, expansion coefficient, a high resistance value. These characteristics limit of this material in the welding must use special methods. But this steel high corrosion resistance, and its not easy to cause a fracture.
Third, passivation, phosphating method. Carbon steel, there are a lot of parts are used in the manufacturing of the dryer. If you work long hours, it is easy on the surface to cause a lot of rust, they have to perform a large number of artificial rust. Passivation, phosphating method mainly by electrical and electrochemical reaction by a one-time treatment, it can enable and full of rust steel workpiece surface showing the original color of the metal, the metal surface to generate a dense anti-rust film. Using this method, even if we put the device placed in a humid environment will not cause rust. But this method is very simple, you can save a lot of manpower and resources, reduce investment, is the most widely used method of corrosion protection.
