How about thermal spraying anti-corrosion of steel structure?

       Thermal spraying anticorrosion of steel structure:



The corrosion of the steel structure is due to the action of the environmental medium, and the iron is oxidized to form a very loose corrosion product. This effect will not stop until it is corroded. The coal mine derrick is the key facility of the coal mine, and the steel structure is the key bearing force for lifting heavy objects. Parts, coal mine derricks are outdoors for a long time, and are easily corroded by the influence of outdoor atmosphere, industrial gas, dew, rainwater and other media. If these corrosions are not effectively protected, the service life of the derrick will be greatly reduced, and the production of coal mines will be seriously affected. Safety, therefore, the anticorrosion of coal mine derricks needs to be paid great attention.

At present, the anti-corrosion of coal mine derrick mainly includes anti-corrosion paint, glass fiber reinforced plastic, hot-dip galvanized anti-corrosion, thermal spray anti-corrosion, etc. Jinan Tianmeng New Material Technology Co., Ltd. adopts flame spraying method to protect coal mine derrick from corrosion. The mixed combustion of oxygen and acetylene gas is used as the heat source to heat the metal zinc and aluminum wires to a molten or high plastic state. Under the leakage of the compressed air flow and the flame flow, the molten and high plastic metal particles are atomized and sprayed onto the surface of the workpiece. The coating formed in this way not only has high bonding strength, but also greatly improves its anti-corrosion performance, effectively improves the service life of the derrick, and improves the safety performance and production efficiency of coal mines

Outdoor steel structures such as steel structure workshops, steel box girder bridges, TV towers, building antennas, transmission and substations, steel light poles, etc. These steel components are exposed to the atmosphere for a long time, and the surface is rapidly oxidized due to climate change and sun and rain. A layer of ferric oxide is formed, which seriously affects the strength and service life of the steel structure. In order to prevent the oxidation of the surface of the steel structure, paint protection is generally used in the past, and its anti-corrosion life is generally 3-5 years, so it needs to be repaired and maintained frequently. The common method is to shovel paint, which consumes a lot of manpower and material resources. The surface of the steel structure is now protected by spraying zinc and aluminum, and the anti-corrosion life can reach more than 30 years without maintenance.
