Cyanide-free alkaline zinc brightener galvanized Galvanized roll

Cyanide-free alkaline zinc brightener RC alkaline non-cyanide zinc brightener is my company developed a new generation of environmentally friendly zinc brightener, with a wide range of current densities bright, bright white coatings are well coated; brittleness low , it has a good tolerance for impurities and other distinctions. Technology characteristics 1. bright area is wide, over a wide current density range 0.1-12A / dm2 can be directly obtained plated mirror bright galvanized 2. Furnishing good, and uniform coating; 3. less brittle coating can be plated with a thickness zinc coating; 4. sexual and throwing deep plating ability, you can get good plating are plated on complex parts; solution composition and operating conditions: raw materials and operating conditions rolling rack plated zinc Zn 8-12g / L 12 -15g / L sodium hydroxide NaoH 100-140g / L 120-145g / L cyanide-free alkaline zinc brightener 6ml / L 6ml / L cyanide-free alkaline zinc walk agent 10ml / L 12ml / L Temperature 10-45 ℃ 10- 45 ℃ Dk (? A dm-2) 1 (0.5-1.2) 0.6 (0.2-0.9) SA: SK 2: 1 2: 1 zinc anode 0 # 0 # zinc ingots time of 2-10 minutes 20-30 minutes to allow auxiliary anode iron iron filters use continuous filtration Continuous filtration solution preparation: 1. open cylinder, the solution in the tank by adding 1/3 of the water feature. 2. Carefully added the required amount of sodium hydroxide solid, not too fast, paying attention to heat, stirring to dissolve. . 3. Serve hot adding zinc oxide and stir until completely dissolved 4. After bath cooling, water was added to a predetermined volume; various additives 5. Finally, add more, you can begin trial plating. Device Requirements: plating tank: plastic lined steel tanks or plastic tank. Loop filter: filter pump can at least an hour in the bath filtered four times. Brightener supplement must be strictly controlled and maintenance 1. Zn / NaoH ratio should be 1: 10-1: 15 2.RC range brightener, consumption of 100-150ml / KAH, galvanized summer temperatures are high, consumption bigger barrel plating and rack plating consumption are also differences: 3.RC walk synchronization agent and brightener added, consumption of 50-100ml / Kah amount depending on the shape of the workpiece with the amount of how much additional; 4. encountered impurities pollution, when hard water level is too high, add a cleaning agent treatment: 5. brightener complementary approaches should be adopted in principle a few times, after brightener diluted fill into. Environmental protection and product safety in order to avoid harm to people and the environment, access to product safety and environmental protection instructions manual is necessary. The company's product safety data sheet (MSDS) contains these instructions. Warranty 1. Our responsibility to provide effective legal guarantees in a range of product quality. 2. customers on product quality re-packaged not in my company's warranty. 3. In use, regardless of the user have any questions, our technical staff will be happy to answer. Color and packaging cyanide-free alkaline zinc primary light brown liquid agent, plastic barrel.
