Shenzhen zinc alloy plating

Chemical materials analysis focuses on the chemical industry mature products (such as rubber, paint, adhesives, plastics, cleaning agents, metal surface treatment, release agents, flux, various additives, etc.) in the development and formulation improvements, provide the basis for recipes, auxiliary enterprises and research institutions to promote research and development progress. Sky plating technology uses sophisticated separation technology, advanced large-scale spectrometer (IR, NMR, GC-MS, LC-MS, TGA, DSC, etc.), sound maps database, leading experts pattern interpretation, strong material library, to Qualitative and quantitative analysis of chemical materials, as well as research and development to verify the individual components, thus shortening the development cycle and promoting the progress of the entire development. Metal surface in a variety of heat treatment, machining, transportation and storage process will inevitably be oxidized to produce a layer of uneven thickness of the oxide layer. It also vulnerable to oil pollution and other impurities adsorption. Oil and certain adsorbate, thin oxide layer can be washed with a solvent cleaning, chemical treatment and mechanical treatment, or treatment with a chemical treatment direct and aluminum plating. For severe oxidation of the metal surface, the oxide layer is thick, it can not be directly solvent cleaning and chemical treatment, and the best first mechanical processing. Typically after aluminum plating metal surface having a high degree of activity, it is more likely to be again contaminated dust, moisture and the like. To this end, the treated metal surface should be glued as quickly as possible. By metal storage of different treatment as follows: aluminum (1) wet sandblasting, 72h; (2) chromic acid - treated aluminum alloy, 6h; (3) anodized aluminum, 30 days ; (4) sulfuric acid treatment of stainless steel, 20 days; steel (5) Sandblasting, 4h; (6) brass wet sandblasting, 8h. If the subdivision, then, aluminum plated metal surface treatment process are phosphate coating, spray painting, electroplating electrophoresis, black oxide, coloring dye, anodizing, chemical polishing and so on. Simply summarized as follows: 1, the metal surface hardening (surface heat treatment) 2, the chemical surface heat treatment, comprising: carburizing, nitriding, carbonitriding, etc. 3, the surface deformation strengthening: to make healthy plastic deformation at room temperature, A surface hardening process, including: blasting, rolling, four, surface coating strengthened, comprising: a metal coating, metal coating, metal carbide coating, non-metallic cladding layer 5, the oxidation (blue) 6, phosphate metal surface treatment process is necessary in our processing step the metal member, the surface treatment is not performed, then, the metal member occurs oxidation, rusting and so many problems in the processing, production and transportation. So that the metal surface treatment process is a must that we must understand.
