Aluminum surface quality requirements: 1, the surface should be clean and rust-proof aluminum plate dealer, does not allow cracks and oxidized debris. 2, the plate surface allows indentation, scratch, roll indentation defects Jinan rust-proof aluminum Which is good, but its depth can not exceed the allowable negative deviation sheet and ensure minimum thickness. 3, the process allows clad slab off portion and the clad bubble cladding layer. 4. In addition to the plate surface to allow repair defects in the thickness difference range. 1, surface treatment of aluminum surface treatment at present mainly in the following categories: electrostatic spray, paint, roller, roller pearl, film. Where the electrostatic spray, paint, roller, roller pearl, film. Where the electrostatic spray, paint short life, prone to chromatic aberration, roller, roller pearl centered life rust-proof aluminum plate, no color supply rust-proof aluminum manufacturers, film faced plywood can be divided into ordinary film with imported film, ordinary film Compared with the lower roller plate life, and life is basically imported films can reach 20 years does not change color. Which is good quality rust-proof aluminum | rust-proof aluminum | aluminum rolls provided by Jinan Heshun Aluminum Limited. Jinan Heshun Aluminum Co.
