(1) anodizing: The surface pretreated aluminum coil aluminum corrosion insulation manufacturer, under certain conditions, the substrate surface anodic oxidation to produce a layer of dense, 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 deposited some salt corrosion insulation supplier of aluminum coil, 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. Notes aluminum drilling a borehole, drilled aluminum selecting drilling machines, the most want to choose only one of a pneumatic drill, the choice to use when loading the tap collet, to choose with torsion Protection collet, so corrosion insulation aluminum coil manufacturers, timely is in the process of drilling there have been some problems, but also to ensure the tap will not slip case corrosion insulation aluminum coil, and can guarantee will not have rotten teeth Taps have broken the case. 2, the last when drilling aluminum, to use the most appropriate drilling oil, so as to ensure that drilling will not be blocked when the problem, leading to a standard diameter is too large, to better guarantee the borehole. Which is good corrosion insulation aluminum coil reputation, corrosion insulation aluminum coils, rolls Alcoa Aluminum Co., Ltd. is provided by Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) is a professional, "aluminum, aluminum, aluminum, aluminum rod, aluminum row, aluminum, aluminum, aluminum elbow" of the company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "aluminum, aluminum, aluminum, aluminum coil, aluminum rod" brand has a good reputation. We adhere to the "service first, customers first" principle, so that cis Alcoa won the trust of customers in all aluminum products, and establish a good corporate image.
