BY-71 type passivation solution

1 Introduction

Our company is easy to rust in the wet or harsh environment for the phosphating workpiece. By using the advanced technology formula at home and abroad, BY-71 passivation solution is used to make up for the deficiencies of rust after phosphating. A major breakthrough is the ideal rust inhibitor for phosphating products.

2, the main features

2.1 There is a corrosion inhibitor in the product, which is not easy to produce excessive corrosion while preventing rust.

2.2 This agent can be compatible with ordinary water and does not affect the adhesion of the coating.

2.3 Use at room temperature to save energy.

3. Scope of application

Suitable for the treatment of ferrous metals, non-ferrous metals, stainless steel with iron products and mechanical parts.

4, typical process

Degreasing→Washing→Derusting→Washing→Neutralization→Washing→Table Adjustment→ Phosphating→Washing→Petivation

5, technical indicators

6, preparation and adjustment

6.1 When preparing the working fluid, add BY-71 type passivation solution in a proportion of 50kg per ton of tap water and stir evenly.

6.2 After using the working fluid for a period of time, its anti-rust effect will decrease. Appropriate amount of BY-71 type passivation solution should be added to ensure the treatment effect of the working fluid.

6.3 When the acid ions and sodium ions in the working fluid exceed the irregular amount, the effect will decrease, and the working fluid should be considered.

7, matters needing attention

This agent can only be used as rust prevention between workpieces. It is necessary to control the concentration and pH of the agent. Continuous production is recommended to be replaced once a month.

8, packaging, storage and transportation

Packed in 25kg plastic drum, stored in a cool dry place, the bucket mouth is up when transported to prevent leakage.
