Stainless iron passivation solution shall be used for rust prevention
Many stainless steel products manufacturers have doubts about why stainless steel is so easy to rust? What is a good method for rust prevention of stainless iron? How can stainless iron materials withstand high salt spray test? How to prevent the rusting of stainless iron? Here are some questions from jiayimei rust prevention experts

The reason why stainless iron rusts: because of its low nickel content, its rust prevention performance is not as good as that of 30 series stainless steel
After some pretreatment, the original metallographic structure of some stainless iron workpieces is broken, resulting in easy rusting
So how can we prevent it from rusting? Of course, jiayimei brand stainless iron passivation solution is selected for passivation treatment
So, everyone's doubts come again
What is the passivation of stainless iron? How to operate the stainless iron passivation solution? The following will introduce the advantages of stainless iron passivation solution and its operation process

Overview of stainless iron passivation solution:   This product is mainly used for Natural Color Passivation of all Ferritic and martensitic stainless steel materials, such as 400 series 1Cr13, 2Cr13, 3Cr13, sus416, sus420, 430 and other types of stainless steel
It is used to improve the corrosion resistance of materials
The treated workpiece does not change the size and color, and the rust prevention ability can be increased by 6 to 100 times
It can be rust free after 780 hours of neutral salt spray test
As a result, a very thick layer will be formed on the workpiece surface during passivation A compact and indestructible conversion film
It is widely used in the fields of food machinery, medical devices, communication equipment, motor shaft cores and pressure vessels, and has a very broad prospect

Conventional process flow:
Degrease — Floating water — Passivation — Floating water — Stabilization — Floating water — Soak in pure water — Drying packaging
The above processes can be increased or decreased as required
Precautions:
1
  Passivation containers can generally adopt plastic frames, plastic tanks and stainless steel tanks

2
  The passivation temperature is 70 ℃ for 30 minutes, and the stable temperature is 65 ℃ for 15 minutes

3
  The passivation solution contains no harmful substances and is environmentally friendly

4
  Through the national unified blue dot method, there is no blue dot in 35 seconds

5
  Operators shall wear labor protection equipment during operation to avoid contact between liquid agent and skin

6
  Waste water treatment, neutralization with alkaline lime water or sodium hydroxide, etc
, and discharge when the pH value reaches 7, which has no impact on the environment
