Anodic oxidation is the electrochemical oxidation of metals or alloys.Aluminum and its alloys in the corresponding electrolyte and the specific process conditions, due to the application of current ,the Aluminum products (anode)to form a layer of oxide film process.
Anodized film with high hardness and wear resistance ,strong adhesion ,strong adsorption capacity ,good corrosion resistance and electrical insulation and high thermal insulation .
Metal plate coating technology is the plastic film and plate through high temperature hot pressing ,the film attached to the metal plate processing technology film processing Because do not use adhesives ,solvents
,it does not contain formaldehyde and the plastic more varieties ,waterproof ,fireproof,with excellent durability superior performance .
Common plastic films are:polyvinyl chloride (PVC),polypropylene(BOPP) and polyester(PET) film.
According to the coating process by the use of raw materials and equipment can be divided into the coating process and pre-coated film coating process.
