Steel factory direct electrolytic degreasing powder

 Steel is a high-temperature electrolysis degreasing powder alkali, strong penetration, emulsifying surfactants and builders and other preparation, it is suitable for steel parts cathodic and anodic electrolytic degreasing, stripping, with significant significant oil decontamination capability, washed well, and can live a good surface to improve adhesion substrate and coating. Process parameters 1, the amount of 50ml / L 2, temperature: hot dip 50 --- 60 ℃ 3, the current density: 1 ~ 8 A / d㎡ 4, plate: Stainless steel plate 5, Time: Anode: 0.5 --- 1 minute cathode: 1 --- 3 minutes Guide a pro rata amount of grooving, magnetic, elastic member should use the anode electrolytic degreasing. 2, after a period of time if the cleaning effect is reduced, it is recommended once every eight hours analyzing the bath, the working fluid per cubic meter plus 2.5Kg, alkalinity increase a little; working solution can be used repeatedly. 3, alkalinity analysis: Take 10ml bath plus 20 ~ 30ml of distilled water in a conical flask, drip 3-4 drops of phenolphthalein indicator drops to 0.1 standard H2SO4 until colorless, 0.1 H2SO4 milliliters that is consumed for alkalinity. 4, in order to prevent contamination of the metal ions to ensure clean, the electrolyte must be periodically corrugated board small current cathodic treatment. Note 1, the product should be stored in a dry, cool place. 2, degreasing powder added to the bath must be completely dissolved before the operation, added after the dissolution proposal to join the working fluid in a container.
