Zhejiang Stainless Iron Passivation Liquid ID4000-1 Wholesale Manufacturer

Stainless iron passivation liquid product description:
It is a low-temperature weak acid passivation product. The passivated product will not change its color, size, or mechanical properties. This product is a colorless and transparent solution. Compared with the old version, passivation of this product effectively prevents red substances from adhering to the product surface. The low-temperature operating conditions effectively reduce the customer's production costs and greatly improve the production efficiency. Overall effectiveness.
Conditions of use:
The solution must be heated to ~℃, and the product can be soaked for 3 seconds
Product data display:
Relative density (℃): .3~
Acidity :~
Color: colorless transparent liquid
Applicable products:
Passivation and anti-corrosion treatment of screws, pins, precision mechanical transmission parts, communication equipment and other fasteners
Process flow:
Oil removal and degreasing (removal of scale and iron powder) - water passing - passivation
Water passing and water coordination
- Water passing and water neutralizing and water passing - Water passing and pure water passing -Drying
First clean the workpiece to be processed, then put it into the solution and soak it for 3 minutes, then take it out and process it with water. Because passivation can not keep rust for a long time, we also Coordination processing must also be carried out to reduce the contact between the workpiece and the air to achieve the anti-oxidation effect and extend the anti-rust time.
