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 board pearl pattern aluminum pointer centered life, no color professional production pointer pattern aluminum manufacturers, film panels can be divided into ordinary film with imported film Jinan pointer pattern aluminum, ordinary film and roll plate is lower compared to the life, and the life of the film basically imports reached 20 years does not change color. (1) anodizing: surface-pretreated aluminum, under certain conditions, the anodic oxidation of the substrate surface, a layer of compact, AL203 film porous, strong adsorption force. (2) sealing: the film hole pores of the porous anodic oxide film after oxidation closed, so that the oxide film pollution, corrosion and wear resistance enhancement oxide film was colorless and transparent, the use of the oxide film before sealing. strong adsorption, adsorption pores in the membrane of some metal deposition Shandong pointer pattern aluminum manufacturers, aluminum exterior can show many qualities other than color, such as: black, bronze, gold and stainless steel color and so on. (3) Surface preparation: chemical or physical methods of cleaning the aluminum surface, bare pure base, to facilitate obtaining a complete, dense artificial oxide film can also be obtained specular or matte (matt by mechanical means. ) surface. Pattern aluminum pointer, pointer-type pattern aluminum factory in Jinan, Jinan cis cis Alcoa Aluminum Co., Ltd. provided by. Jinan Heshun Aluminum Co. (www.jnhsly.com) in the field of aluminum products devoted boundless enthusiasm and passion, rolls Alcoa has been customer-centric, for customers to create the concept of value, quality and service to win market share sincerely hope to cooperate with the community to create success, create brilliant.
