The five meridian accessories of furniture are easy to rust, is there any way to get rid of rust?

1. Small pneumatic or electric rust removal. It is mainly powered by electricity or compressed air, equipped with appropriate rust removal devices, and carries out reciprocating motion or rotary motion to meet the rust removal requirements of various occasions. Such as angle grinder, wire brush, pneumatic needle beam deruster, pneumatic knocking rust hammer, tooth type rotary deruster, etc., belong to semi-mechanized equipment, the tool is lightweight, maneuverable, can remove rust and old coating more thoroughly, can carry out hair treatment on the coating, the efficiency is greatly improved than manual rust removal, up to 1 2m2 h, but can not remove the oxide scale, the surface roughness is small, can not achieve high-quality surface treatment quality, the work efficiency is lower than the jet treatment.

It can be used in any part of the body, especially in the process of ship repair.

2. Shot peening (sand) rust removal. It is mainly composed of particle jet erosion to achieve surface cleanliness and suitable roughness, and the equipment includes open shot peening (sand) rust removal machine, closed shot peening (sand chamber), vacuum shot peening (sand) machine. The open shot blasting (sand) machine is widely used, which can completely remove all impurities on the metal surface, such as oxide scale, rust and old paint film, with a high rust removal efficiency of 4 5m2 h, a high mechanical degree and good rust removal quality.

However, because the abrasive generally cannot be recycled, it has an impact on other operations and is troublesome to clean up the site. Therefore, the environmental pollution is heavier, and the use has been gradually restricted recently.

3. High-pressure water abrasive rust removal. The impact action of high-pressure water jets (plus the grinding action of abrasives) and water skid are used to destroy the adhesion of rust and coating to steel plates. It is characterized by no dust pollution, no damage to the steel plate, greatly improving the rust removal efficiency, up to more than 15m2 h, and good rust removal quality.

However, the steel plate after rust removal is easy to return to rust, and it is necessary to coat a special wet derusting coating, which has a great impact on the coating of general performance coatings.

4. Shot blasting and rust removal. Shot blasting is the use of high-speed rotating impeller to throw abrasive to the surface of steel to achieve the purpose of rust removal, is a more advanced mechanical treatment method for hull steel rust removal, not only high production efficiency, but also low cost, high degree of automation, can realize assembly line operation, less environmental pollution, but only indoor operation.

3) Chemical rust removal is mainly a rust removal method that uses acid to react with metal oxides to remove rust products on the metal surface, that is, pickling and rust removal, which can only be operated in the workshop.
