Description

Technical Field

[0001] The utility model relates to the technical field of aluminum single plate processing, in particular to an aluminum single plate surface processing device. Background Art

[0002] Aluminum veneer refers to a building decoration material that is processed by chromization and other treatments and then processed by fluorocarbon spraying technology. Fluorocarbon coatings mainly refer to polyvinylidene fluoride resin (KANAR500), which is divided into three types: primer, topcoat, and varnish. The spraying production of aluminum veneer is divided into two steps: the first step is sheet metal processing. This process mainly involves cutting, folding, bending, welding, grinding and other processes to process the aluminum veneer into the shape and size required for construction. The second step is spraying, which is spraying paint on the processed sheet metal. There are two types of spraying, one is manual spraying and the other is machine spraying. When aluminum veneer is being processed by sheet metal, after cutting the aluminum veneer, the surface of the plate needs to be polished and other surface treatments, so that the paint can be sprayed more evenly during the subsequent spraying process.
