In the daily life, how does Stainless Steel Hanging Light rust? Here are some tips for removing rust.
1. Small air or electric rust removal. Mainly powered by electric or compressed air, equipped with appropriate descaling device, reciprocating or rotating motion to meet the rust removal requirements of various occasions. Such as angle grinder, wire brush, pneumatic needle rust remover, pneumatic rust hammer, tooth type rotary rust remover, etc., is a semi-mechanical device, the tool is light, maneuverable, can completely remove rust , old coating, etc., can be applied to the coating, the efficiency is much higher than manual derusting, up to 1~2m2 / h, but can not remove the scale, the surface roughness is small, can not achieve high quality surface treatment quality The work efficiency is lower than the spray treatment. Can be used in any part, especially in the ship repair process.
2, shot blasting. It is mainly composed of particle jet erosion to achieve surface cleaning and suitable roughness. The equipment includes open shot blasting machine, closed shot blasting and vacuum blasting machine. The open type shot blasting machine is widely used, which can completely remove all impurities on the metal surface, such as scale, rust and old paint film. The rust removal efficiency is 4~5m2/h, the mechanical degree is high, and the rust quality is good. However, it is generally impossible to recycle due to abrasives, which has an impact on other operations and troubles in cleaning the site. Therefore, environmental pollution is heavier and has recently been restricted.
3. High-pressure water abrasive rust removal. The impact of the high pressure water jet and the action of the water raft destroy the adhesion of the rust and the coating to the steel sheet. Its characteristics are no dust pollution, no damage to the steel plate, greatly improve the rust removal efficiency, up to 15m2 / h or more, good derusting quality. However, the steel plate after rust removal is easy to return to rust, and it is necessary to apply a special wet rust-removing paint, which has a great influence on the coating of general performance paint.
4, shot blasting. Shot blasting is the use of a high-speed rotating impeller to throw the abrasive onto the steel surface to achieve the purpose of rust removal. It is a relatively advanced mechanical treatment method for rust removal of hull steel, which not only has high production efficiency, but also low cost and automation. The degree is high, the pipeline operation can be realized, and the environmental pollution is small, but it is only operated indoors.
