Small electrophoresis electrophoresis pipeline pipeline _ _ electrophoresis pipeline monopoly over wisdom

1 oil painting process: If Acid Recovery electrophoresis line equipment, recommended alkaline degreasing, due to alkaline degreasing, aluminum surface is bright, and the side effects associated with the back of the base does not eclipse, as with alkaline degreasing, whose main ingredient is Na 2 CO 3 and NaOH. 2 water: tap water to wash away the acid or base before the procedure. 3 Eclipse: adding an alkali etchant alkaline etching process reduces surface brightness profiles, but the effect is not very obvious main tank should be careful not to make Al 3 content is too large, the temperature is too high, or easy to produce not wash spotted After drying painted yellow. Two wash: the best there is spraying or increase the overflow, in order to ensure a thorough cleaning. Ash: with HNO 3 good results, but pay attention to strengthening water (at least two channels + shower). Washing: Water with H 2 SO 4 ash, a water can, with HNO 3 ash, need two water. Oxidation: H 2 SO 4 oxidation is generally 20min, so that the oxide film reaches 9u, some companies selling so-called high-temperature oxidizing agent, the main ingredient is a mixed acid is not recommended, the oxide film of color, hardness, coloring There were no benefits. Washing: water two to increase the overflow. Coloring: single tin salt, single nickel salt, tin-nickel complex salt can be, be careful not to have a color, because the color will increase in the electrophoretic coating. Washing: spray electrophoresis plus the best lines, in order to minimize post-procedure into the amount of acid. Hot pure water: Requires conductivity <100us / cm, temperature 70-80 ℃, PH = 4-6, especially silver oxide coating profiles or voltage greater profile in this slot should handle longer time, PH Triethylamine value can be adjusted. Pure water: Requires conductivity <100us / cm electrophoresis pipeline quotes, temperature, PH = 4-6, 2-4 minutes to process. PH value can be adjusted as triethylamine. About a related electrophoresis equipment, water equipment: The main two, ion exchange and reverse osmosis water. Electrophoretic coating of pure water are higher, while the water is only one of the test items: Conductivity (μm / cm). With paint cast groove need water conductivity to reach 10μm / cm or less, to carry out the requirements of clean washing water reaches 50μm / cm or less, or more indicators of water through water equipment is required to be completed, also is manufactured raw water pure desired device. For small production, small-scale electrophoretic coating industrial water users choose to buy more economical way. Ion exchange applicable to raw water conductivity of not more than 200μm / cm, more than 200μm / cm of raw water should be chosen manufacture reverse osmosis water pure, raw water conductivity greater than 1000μm / cm should be selected reverse osmosis water pretreatment Water softening to + pure water production process is completed. Urban water conductivity can call the local water company; groundwater, water, landscape, the conductivity of the water is high, the basic need reverse osmosis water machine to complete the process water system.
