The chemical activity of metal aluminum is very high. It is quickly oxidized in the air to form a natural oxide layer. It must be removed before painting or passivation to ensure the integrity of the film. Common aluminum alloy pretreatment processes are: Degreasing, degreasing, surface adjustment, passivation coating and other auxiliary treatments
The magnesium alloy material is extremely easy to oxidize, resulting in poor corrosion resistance, and it is prone to severe corrosion in corrosive media. General magnesium alloy surface treatments include: cleaning and decontamination-acid etching and descaling-activation-surface tone-passivation (film), and other auxiliary treatments
Common pre-treatment processes and methods for stainless steel are: alkaline degreasing, degreasing and wax removal, wax removal after polishing, bright degreasing cleaning (acid), environmental protection passivation, and other auxiliary treatments
Due to the influence of the environment, the copper surface will be oxidized to different degrees. Therefore, it is also necessary to perform surface protection treatment to keep it bright for a long time, such as new appearance and corrosion and oxidation resistance. Then you need to use a variety of different copper surface treatment processes. Common copper surface treatment processes include: cleaning and degreasing, passivation and oxidation resistance, rust prevention and other auxiliary treatments.
The surface pre-treatment of iron and steel materials can be divided into: degreasing, degreasing, rusting and descaling, surface adjustment, phosphate coating (silane potting), passivation and oxidation resistance, and other auxiliary treatments, including: paint removal and coating removal , Wax cleaning, polishing and brightening, rust and oxidation resistance, Hui Weijia 13 years of focus on steel surface treatment, professional technology, dedicated service!
