Technical Field

The utility model relates to the technical field of grinding and polishing, in particular to a polishing device.

Background

Buildings such as factory buildings are usually made of steel plates to manufacture roofs. The iron and steel can be oxidized into red brown rust in natural environment, and the rust has loose texture and is easy to absorb water. If the steel plate is rusted, rust removal is not carried out, and the rust absorbs moisture to cause the steel plate to rust faster.
