What industries are suitable for metal thermal spraying

       With the development of the industry, metal thermal spraying processing technology can now be applied to many industries. Today, Xiaobian will introduce seven methods to you.



1. Power system:



2. Metallurgical system:



3. Non-ferrous metal industry system:



4. Coal system:



5. Petroleum system:

6. Chemical industry:

1. Metal coating: spraying aluminum, zinc, tin, lead, stainless steel and other anti-corrosion coatings on the inner surfaces of carbonization towers, gas cabinets, brewing storage tanks, beer fermentation tanks, distillation towers, various chemical containers, etc. in chemical fertilizer plants, and repairing large gate valves .



2. Ceramic coating: The inner surface of the newly-made reaction kettle of pharmaceutical, biochemical, food and chemical enterprises is sprayed with AL2O3, Cr2O2, TiO2 and other ceramic coatings after sandblasting and rust removal to replace the glass-lined glaze coating or the partial peeling repair coating of the reaction kettle.



3. Plastic coating: structural parts of gymnasium grids, public facilities, various chemical containers, large-diameter pipes, plates and frames of clay machines in the ceramic industry, cloth guide rollers in the printing and dyeing industry, cast iron rollers for belt conveyors in the coal industry, and various types of printing presses. The surface of the guide rollers and other surfaces is sprayed with nylon anti-friction and wear-resistant coatings, and sprayed with polyethylene, EVA resin, chlorinated polyether, epoxy resin and other anti-corrosion coatings to make up for the lack of electrostatic spraying.



Seven, machinery industry:



1. A large butterfly valve is worth more than 10,000 yuan, and an oil field consumes at least more than 20 large valves a year. According to the annual consumption of large valves in the top ten oil fields in the country, the annual consumption of large valves is more than 200. If you consider the annual consumption of large valves in other industries, the annual consumption is even greater. The use of 1Cr18Ni9Ti material for spray repair can increase the service life by 1-2 times under the environment of 350 ℃, and only this one can obtain economic benefits of more than 10 million yuan in the oil sector; According to the factory survey, the actual service life of domestic 2040 cast iron gate valves is only 720 hours, which is far from the national standard of 3,000 hours. If not required, the loss is considerable.
