Passivation Test Kit Copper Sulfate Solution Introduction

Chrome-free green environmental protection passivation liquid is the double product that our company has developed on the basis of the original passivation solution.Which is our best-selling product.

Principle of passivation: The phenomenon that the corrosion rate of the metal is less than that of the former after metal is treated with oxidizing medium is called metal passivation.

The passivation mechanism is mainly explained by thin film theory,it is considered that the passivation phenomenon is due to the effect of metal and oxidizing medium, and forms a very thin and dense coating passivation film with good properties on the surface of stainless steel products can be strongly attached on the surface of the stainless steel.This passivation film is independent, usually a compound of oxygen and metals.

Scope of application

It plays the role of completely separating the metal from the corrosive medium to prevent the metal from contacting with the corrosive medium directly.So that the metal basically stops dissolving to form a passive state to achieve the effect of preventing corrosion.


Application of Passivation Test Kit Copper Sulfate Solution

1.Suitable for all 300 series stainless steel/For example: 304,316,316L etc Austenitic stainless steel.It can be tested by standard 150-1800 hours neutral salt spray.
