2.Innovation is the cornerstones of Shenzhen Topology Precision Film Technology Co., Ltd.s success. In the future, Topological fine film also hope to continue to innovate, for the majority of customers to provide porous anodic aluminax318b6danservice. Over the years, Topological fine film always believe that only adhere to innovation and professional, in order to better meet customer demand for What is the best porous anodic alumina. details:5.Porous anodic alumina Anodizing of aluminum alloys for construction, decoration and protection is basically the production of porous anodic alumina. For example, the anodizing of sulfuric acid for building 6063 aluminum alloys has a porosity of approximately 11%. The structure of the porous anodic alumina is composed of a barrier layer and a porous layer which are in close contact with the metal substrate. Although the porous property imparts the ability to impart coloration and other functions to the anodized film, corrosion resistance, weather resistance, stain resistance, and the like are unlikely to meet the requirements for use, and therefore micropores of the aluminum anodized film are considered from practical applications. Must be closed. The unsealed anodized film, due to the large area within the micropores, increases the effective surface area of ??the workpiece or sample exposed to the environment by several tens to hundreds of times, and the corresponding corrosion rate is also greatly increased. Therefore, in addition to the wear-resistant hard oxide film, the anodized film of aluminum must be subjected to sealing treatment in consideration of improvement in corrosion resistance and stain resistance.The new national standard in China defines "sealing hole" a |
