Designed for storing large quantities of similar tray goods. Heavy shelves, commonly known as cantilever racking, pallet racking, as part of the pallet rack, in the domestic various common in a form of shelves, storage shelves system with column, floor board and beam all the assembly structure, structure concise and effective. Tray one by one according to the depth direction in guide rail support, zengda storage density, improve the space utilization. So in daily use process will inevitably appear rusty phenomenon, in this case do? Beijing shelves manufacturer to tell you:

Chemical cleaning method is mainly using acid react with metal oxide, so as to get rid of heavy shelves materials on the surface of the metal corrosion product of a cleaning method, also is what we usually call pickling, similarly, the rust removal method is limited to operations within the workshop.

Blasting derusting using high-speed rotating impeller will be abrasive to the heavy shelves steel surface to achieve derusting, shot blasting derusting is a kind of relatively advanced mechanical descaling methods, not only high production efficiency, and low cost high degree of automation, which can realize assembly line operation, less environmental pollution, but the rust removal method is limited to indoor.

Using high pressure water jet impact also can be combined with abrasive grinding effect, and the water lever action of heavy shelves steel corrosion and coating adhesion. The characteristics of the rust removal method is no dust pollution, no damage shelf steel plate, thus greatly improving the efficiency of rust removal, can reach more than 15 m2 / h, derusting quality is good. As the saying goes, "good is bad, although this method of cleaning cleaning efficiency is high, but the heavy shelves steel rust easily return after derusting, painting to bring wet cleaning coating, so that we can effectively guarantee heavy shelves derusting work completed.
