Tubes in the warehouse to prevent the time, then sometimes black, indicating the beginning of a little oxidized aluminum, aluminum oxide, after, you can wipe the oxide, in the sun, irradiation of a few days, you can solve the problem of oxidation, machining aluminum tubes produce 3m length Jinan supply hard anodized aluminum square tube manufacturers can stand tubes for mechanical parts, textiles, electronics, auto parts, communications, cooking utensils, stereo speakers, printing peripheral parts, LED, solar panels such as the oxidation process. Surface treatment of aluminum oxide precursor material composition, the impact of the purity of the oxidation of aluminum oxide film quality for technology workers have long understood. However, in industrial production, surface quality domestic aluminum plate anodized seriously affect the quality of products, the conflict has become increasingly prominent. Abroad have been milled aluminum sheet surface treatment of aluminum square tube supply price, smooth as a mirror, excellent oxidation quality. Before 6061 aluminum oxide, oil processing, most of the factories still use weak alkali degreasing chemical degreasing or caustic soda to whiten, but in recent years, more and more factories using the method of surfactant were added in addition to oil. The use of surfactants unique physical and chemical properties, reduced surface tension, emulsifying, solubilizing and foaming base itself, hard water such as a good chemical stability of the effect to improve the oil purification effect, and the surface layer of the alkaline foam layer aluminum square tube supply prices, inhibiting alkali mist escape, aluminum square tube to reduce pollution and improve operating conditions. State for hardening aluminum by work hardening to increase the strength of the product, the product may be subjected to after hardening (or not pass) reduced the strength of the additional heat treatment. Aluminum code must be followed by two or three roots have Arabic numerals W: an unstable state state solution heat treatment, applies only after solution heat treatment, natural aging of the alloy at room temperature, the state code only indicates that the product is in the nature aging stage T: aluminum heat treatment (unlike F, O, H) suitable heat treatment, after (or without) the work hardening of the product reaches a steady state, T code must be followed by a root or more digits.
