Drying machine common corrosion method

The majority of drying equipment in welding, flat plate, a cylinder body. According to the different uses of the dryer should be carried out anti-corrosion treatment, following the presentation of several building materials corrosion and a method of manufacturing experience.

Phosphating-passivation process

In a vibrating fluidized bed dryer manufacturing,70% parts are steel structure.Process of turnaround time is longer, the surface generation of large amounts of rust, paint before artificial rust.Phosphating_passivation process, using electrical and electrochemical reaction mechanism, through a one-time deal, to rust, showing a metal original color, at the same time in the metal surface to generate compact antirust coating, can be placed in the humid air a few days, will not rust. It has the advantages of simple operation, can improve the working environment, reduces the labor intensity, save manpower and material resources. Phosphating and passivation treatment liquid containing emulsifier, molybdate, soluble phosphate and so on, is not only applicable to the above models, other similar structure or frame can adopt the preservative treatment.

Electrostatic powder coating process

The traditional paint is liquid, which contains a large number of ester ketone and hydrocarbons and other organic solvents, flammable and explosive and is very safe, to production, storage and transportation. The construction inconvenience. Therefore, domestic and foreign experts paint are committed to the development of less or no solution solution of new paint, it is powder coating.

Vibrating fluidized bed dryer cover, is made of cold rolled stainless steel plate, so the cost is very high. Why adopt stainless steel? Because of the equipment in the work of state be exposed to a corrosive material and gas, and the stainless steel plate cold rolled plate.

But the ordinary carbon steel for electrostatic spraying of polyester resin powder coatings, the corrosion resistance of stainless steel can be comparable with. Electrostatic powder coating has tough, durable, good decorative features, and weather resistance and heat resistance, corrosion resistance and resistance to pulverization performance, fully applicable to the drying machine casing corrosion.
