Product Features
This product is made from strong oxidizer, film forming agent, activating agent, buffer and so on. It contains no aluminum, meeting environmental protection requirements. After soaking, a colorless conductive film is formed on aluminum surface, which is of high corrosion-resistance. It meets the need of aluminum coating.
Operating Conditions
Concentration: 80~100g/L
PH: 1.5~1.7(Use phosphoric acid for adjustment)
Temperature: 10~30℃
Time: Soaking for 2~5min
Solution Control
- PH value must be strictly controlled during production. If it too high, use thin phosphoric acid for adjustment; if it too low, adjust PH value by diluting tank liquid.
- Pro-oxidation treatment must be strictly controlled for thorough removal of oil stains and natural oxidized skin on workpiece so as to avoid influencing evenness of oxide film.
- Before oxidation, cleanse it thoroughly to avoid bringing in too much acid/alkaline liquid and polluting tank liquid.
Product Packaging
25kg packaged and sealed plastic bag with outer carton.
