Oxidation anodizing production line principles and characteristics

Anodizing production line principle characteristics of oxide and Shenzhen Elcoteq ultrasound equipment company based oxide market situation and the customer's own production processes and objective requirements, design, develop a new generation of anodized production lines, reduce production costs, to meet customer demand, oxidation equipment, automatic anodic oxidation equipment, the best process, provide the best quality service, the most professional design team, to provide you with cost-effective products. Anodized Rationale: anodizing is the result of an electrolytic oxidation process, aluminum or aluminum alloy as an anode by electrolysis method, the surface of aluminum and aluminum oxide film formed as oxide film change the surface state and performance, this layer of oxide film with surface shading, improve corrosion resistance, abrasion resistance and other properties to enhance hardness, protective, decorative and so on. The thickness of standard aluminum or aluminum alloy surface oxidation is: Chinese national standard is 10-15UM plus or minus tolerance: +5 -1 12-18um international standard is more common features anodized surface coloring and coloring due to the different components of the solution There is divided into three categories coloration, as the first one: Electrolytic coloring of aluminum and aluminum after anodizing, add one containing nickel salts, cobalt salts, tin salts or copper electrolytic solution such as exchanges, so that the bottom film hole nickel, cobalt, tin or copper deposited and showing a different color. The process has simple process, low power consumption, color uniformity, high production efficiency. Second: the organic dye coloring due to oxidation of the porous film having strong adsorption capacity and thus different colors can be dyed. The most appropriate direct colored oxide film is anodized film obtained from the sulfuric acid solution, which the majority of aluminum and aluminum alloy colorless transparent film with a suitable thickness, porosity and adsorption. Than sulfuric acid anodizing process technology for high prices, to give a yellow film. When the film than 50μm to obtain a natural yellow or brown. Chromic acid anodizing process since the film is thin, low porosity, and it itself is gray, the general should not be colored. Colored oxide film thickness of the request is appropriate, there is sufficient porosity and good adsorption capacity, no injuries and pollution. Aluminum and aluminum alloys are listed organic dye coloring process. Third: the overall coloring of aluminum and aluminum alloys into containing organic compounds (such as cresol, acid, sulfosalicylic acid, etc.) electrolyte anodic coloring treatment, but also in anodized colored, small The particles are dispersed in the inner wall of the membrane pores due to scattering of incident light to produce different colors. Tiny particles from the decomposition product of base metal or organic electrolyte, the thickness of the color depth and the film has a direct relationship. The process requires a high due to anodic current density and a high voltage, a large energy consumption. Oxidation of the basic principles can be concluded that oxidation characteristics: ⒈ oxidation product consistent uniform color, not easy to fade; 2. strong hardness: suitable for specialty alloy products, stainless steel but weighs only one-third; 3 . weather resistance, UV resistance, scratch 4. antistatic no dust, easy to clean, without leaving fingerprints after touch; 5. nontoxic; and high temperature 6. strong sense of metal: beautiful, high-grade, bright colors 7. anodizing production line can be mass-produced, high volume production
