The main process is:
(1) Surface pretreatment: the surface of aluminum alloy outdoor tent poles of aluminum alloy is cleaned by chemical or physical methods to expose and remove the pure matrix, so as to obtain complete and dense artificial oxidation film.A mirror or matte surface can also be obtained mechanically.
(2) anodic oxidation: under certain technological conditions, anodic oxidation occurs on the surface of the aluminum alloy outdoor tent poles pretreated on the surface to produce a film layer with dense, porous and strong adsorption force.
(3) hole sealing: the membrane pores of the porous oxide film generated after anodic oxidation are closed to enhance the anti-pollution, anti-corrosion and anti-wear properties of the oxide film.Oxidation film is colorless transparent, the use of unprecedented oxidation film absorption, adsorption and deposition of some metal salt in the film hole, can make the aluminum alloy outdoor tent poles appearance appears the natural color (silver white), such as: black, bronze, gold and stainless steel color,ect .
