Be careful not to soak the rusty shelves in dilute hydrochloric acid for too long, otherwise the materials inside will be reacted by the way after removing the surface rust from the shelves. For example, after removing rust, it will react with iron. Rust can be removed from the shelves using small air or electric motors. This method is mainly powered by electricity or compressed air, equipped with appropriate descaling devices, and reciprocating or rotating to meet the derusting requirements of various shelves.

Such as angle grinders, wire brushes, air-driven pin beam rust removers, wind-driven rust hammers, and tooth-shaped rotary rust removers, etc., are semi-mechanized equipment, with lightweight tools and high mobility, which can remove rust more thoroughly. , Old coatings, etc., can coat the shelf 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 and ergonomics are lower than spray treatment.
Can be used anywhere on the shelf, especially in large warehouse logistics centers.

High-pressure water abrasive for rust removal. The impact of the high-pressure water jet (plus the grinding of the abrasive) and water prying are used to destroy the corrosion and the adhesion of the coating to the steel plate of the shelf. Its characteristics are no dust pollution, no damage to the steel plate on the shelf, greatly improving the rust removal efficiency, up to 15m2 / h, and good rust removal quality. However, after the rust removal, the steel plate on the shelf is easy to return to rust. It must be coated with a special wet rust removal coating, which has a great impact on the coating of general performance coatings.
Shot blasting is the use of high-speed rotating impellers to throw abrasives to the steel surface of the shelves to achieve the purpose of rust removal. It is a relatively advanced mechanical processing method. It not only has high production efficiency, but also has low cost and high degree of automation. , Less environmental pollution, but only indoor operation.

Chemical rust removal is mainly a method for removing rust products from metal surfaces of shelf materials by chemical reaction between acids and metal oxides, which is commonly referred to as pickling and rust removal, and can only be operated in the workshop.
