After using the shelf for several years, some rust will inevitably occur. Shopping Trolley manufacturerAt this time, in order to make the shelf beautiful, we need to remove the rust on the shelf ourselves.

Please be careful not to soak the rusty shelf in dilute hydrochloric acid for too long, otherwise the substances inside will react after removing the rust on the surface of the shelf. For example, in addition to rust, it will react with iron.

Can use small pneumatic or electric to remove the rust on the shelf.

This method is mainly powered by electricity or compressed air and equipped with appropriate derusting rack equipment for reciprocating motion or rotation Exercise to adapt to the derusting requirements of shelves.

Tray type shelves, such as angle grinder, steel wire brush, pneumatic needle beam derusting device, pneumatic rust hammer, tooth type rotary derusting device, are semi mechanized equipment. They are light in East and West and have great mobility. They can roughen the shelf coating compared with derusting and old coating. The power is better than manual derusting, up to 1 ~ 2M2 / h, but they can not remove oxide scale and have small surface roughness, Shopping Trolley manufacturerThe surface treatment quality cannot be reached, and the work efficiency is lower than that of spray treatment.

It can be used in the shelf position and in the shelf logistics base of large warehouse.

High pressure water abrasive derusting. The impact of high-pressure water jet (plus abrasive grinding) and water skid damage, corrosion and coating adhesion to shelf steel plate are used. It is characterized by no dust pollution, no damage to shelf steel plate, rust removal power of more than 15m2 / h, Shopping Trolley manufacturer and good rust removal. However, the shelf steel plate after derusting is easy to rust back, so it must be coated with a special wet derusting coating, which has a great impact on the coating of general functional coatings.

Shot blasting is to use the high-speed rotating impeller to throw the abrasive to the steel surface of the shelf to achieve the purpose of rust removal. The laminate shelf is a relatively good mechanical treatment method. It not only has high production power, but also has low cost and high degree of automation. It can complete the assembly line Cao, with less environmental pollution, but only in the indoor Cao.
