　　After several years of shelf operation, there will inevitably be some rust attack. At this time, for the beauty of the shelf, we need to decontaminate the shelf by ourselves.

　　European Standard Storage reminds you not to soak the rusty shelves in dilute hydrochloric acid for too long, otherwise the rusty shelves will react the substances inside. For example, in addition to rust will react with iron.

　　It can remove rust on the shelf by small pneumatic or electric.

　　This method mainly uses electricity or compressed air as power, installs appropriate derusting rack equipment, carries on the reciprocating movement or the rotation movement, in order to adapt to the derusting request of the rack.

　　Pallet shelves, such as angular polishers, wire brushes, pneumatic needle bundle rust removers, pneumatic hammers, gear-type rotary rust removers, are classified as semi-mechanized equipment. They are lightweight, flexible, and are better than rust removal and old coatings. They can wool shelf coatings with a power of 1 to 2 m2/h, but they can not remove oxide scales. Their surface roughness is small and can not be reached. To achieve surface treatment quality, the work efficiency is lower than that of eruption treatment.

　　It can be used in shelf location and in large warehouse shelf logistics base.

　　High pressure water abrasive rust removal. The impact of high-pressure water jet （with abrasive grinding） and prying damaged the corrosion and the adhesion of coating to shelf steel plate. Its characteristics are no dust pollution, no damage to the shelf steel plate, rust removal power, up to 15,52h, good rust removal. However, the shelf steel plate after rust removal is easy to rust back, so special wet rust removal coatings must be applied, which has a great influence on the coating of general functional coatings.

　　Blasting rust removal is to use high-speed rotating impeller to throw Abrasives onto the steel surface of the shelf to achieve the purpose of rust removal. Laminated shelf is a relatively good mechanical treatment method. It not only has high output power, but also has low cost and high automation. It can complete pipeline operation with less environmental pollution, but only operates indoors.
