Product Description Aluminium Profile Anodizing Line Product General IntroductionMeet the China national standard GB/T6892-2006 and Europe standard EN12020-1, (2001) and American Standard ANSI H35.2-2003.We are a trustworthy supplier, constant business partner and sincere friend.We've dedicated in providing turn-key solutions for aluminium profile anodizing production line for 20 years.We have got ISO9001:2000 certification and the durability of our anodizing line exceeds the similar products about 50%. We can customize anodizing production line to customer requirements. And we are well known in this industry both home and abroad.1. Anodizing Process Chat1) Dg = Degreasing 2) Rs = Rinsing, HW Rs = Hot Water Rinsing 4) AD = Alkaline Degreasing 5) Et = Eutralization 6) Od = Oxidation 7) Sl = Sealing 8) MU = Material Unloading 9) Pc = Packing 2.

Due to working time will produce alkali mist which is toxic gas, it have to install an exhaust fan in both side of the tank, if the absorb effect not good which cause the gas slowly to be throw out, it will effect to workers respiratory system, corrosion to the electric equipment, dot appearance to the profile, effect to coloring process and electrophoresis process.Sulfuric acid + Nitric acidSulfuric acid contentNitric acid Temperature100 g/L34~45g/L3~8/minAnodizingAnodizing voltageCurrent densityTank solution temperatureSulfuric acid concentrationAluminium ion concentrationAnodizing time12-18V1~1.6A/dm218~22oC140~180g/L<20g/L20~36minProduction resultsDue to anodizing process will produce a mass heat, but the process itself need common temperature, so it's using the cycling cooling process to reduce the temperature. Aside when the anodizing process is working it will produce a toxic mist gas which have strong smell, so it must need to install exhaust fan to protect it, if the absorb effect not good which cause the gas slowly to be throw out, it will effect to workers respiratory system, corrosion to the electric equipment, dot appearance to the profile, effect to coloring process and electrophoresis process.EquipmentChemical pump, heat exchanger, chiller, anodizing power supply (rectifier), exhaust fan.Electrolytic coloringStannous sulfateSulfuric acidColoring stabilizerPH valueTemperatureVoltage5~10g/L0.8A/dm218~22oC1~2g/L<18~20g/L17minEquipment Alternation current power supply, heat exchanger, chemical pump, filter equipmentNormal Temp.
