PH value | 1.0~2.2 |
Application industry | Screws, pins, precision mechanical transmission parts, communication equipment and other fasteners |
Precautions | 1. According to our research experience, it is not recommended to use acid solution containing Cl ions (such as HCl, NaCl, etc.) for pre-treatment in pickling/activation process. If it cannot be avoided due to special reasons, please soak the workpiece in 70-80 ℃ hot water for 3-5 minutes after pickling before passivation. 2. It is recommended that the chloride ion content in the purified water should not exceed 25PPM in the occasion with high passivation performance requirements. |
Quality index inspection method | Suck 5ml of working solution into a 250ml conical flask with a pipette, add 50ml of distilled water to dilute and shake up, add 2-3 drops of 1% methyl orange indicator, titrate with 0.1mol/L standard NaOH solution to pink as the end point, and the N ml consumed is the acidity. |
