Stainless steel environmental protection passivation solution

  l  Main uses of stainless steel passivation solution: l  [stainless steel passivation solution] 304 stainless steel passivation solution is a newly developed new generation of green and environment-friendly chromium free stainless steel passivation solution
It comprehensively pickles and passivates stainless steel to remove all kinds of dirt such as oil, rust, oxide skin and weld spots
After treatment, the stainless steel surface becomes uniform, bright, silver white and beautiful
It greatly improves the corrosion resistance of stainless steel and the added value of products
It is especially suitable for 304, 304L, 316, 316L, 321 and other stainless steel parts Cleaning and brightening of plates and their small equipment, such as chemical machinery plant, petrochemical equipment plant, stainless steel products plant, mechanical processing plant, stainless steel processing plant, head plant, hardware products plant, etc

l  [stainless steel passivation solution] 304 stainless steel passivation solution is our substitute product based on the original passivation solution after years of research and development
It is the first chromium free green environmental protection product in China and is our best-selling product
The passivation principle: the phenomenon that the corrosion rate of metal after treatment with oxidizing medium is significantly lower than that before the original treatment is called metal passivation

l  The passivation mechanism can be explained mainly by the film theory, that is, the passivation is due to the interaction between metal and oxidizing medium, and a very thin, dense, well covered passivation film can be formed on the metal surface, which can be firmly attached to the metal surface
This film exists as an independent phase, usually a compound of oxygen and metals
It plays the role of completely separating the metal from the corrosive medium, preventing the direct contact between the metal and the corrosive medium, so that the metal basically stops dissolving and forms a passive state to achieve the effect of preventing corrosion

l  Operation process:
l  Stainless steel high salt fog normal temperature immersion passivation solution original solution immersion for 15 minutes, take out and wash with clean water
l  Typical process:
l  Pretreatment &mdash& mdash; Rinsing &mdash& mdash; Activation &mdash& mdash; Rinsing &mdash& mdash; Passivation &mdash& mdash; Rinsing &mdash& mdash; Neutralization &mdash& mdash; Rinsing &mdash& mdash; dry
l  The purpose of activation is to expose the metal matrix on the surface of stainless steel, so as to facilitate the direct contact between the chemical solution and the metal surface, so as to achieve a higher salt spray time
The workpieces with clean surface, free of oxide scale and rust can be passivated directly if they are subject to electrolytic polishing, chemical polishing and mechanical grinding and polishing
l  Characteristics and advantages of jiayimei stainless steel passivation solution:
l  1
After passivation, it will not change any size and color of the workpiece, and effectively protect the beautiful appearance and accuracy of the workpiece

l  2
The use cost is low, the liquid medicine can be reused, and the antirust grade of the material is changed from secondary to strong (201 to 304, 304 to 316… …) Enhance product added value and effectively reduce enterprise costs

l  3
Strong corrosion resistance after passivation
201 series materials have passed salt spray test for more than 48 hours and 304 series materials for 200~2000 hours
l  4
Simple operation, stable performance of stainless steel passivation solution, just soaking at room temperature

l  5
The passivation solution does not contain harmful substances, meets the environmental specifications of RoHS and reach, and has passed the tests of SGS, FDA, etc

l  6
It is widely used in food machinery, hardware and electronics, pressure vessels, communication equipment and other fields

l  7
Passivation soaking time at room temperature for 10 minutes 8
Containers for passivation can generally adopt plastic boxes, plastic tanks and stainless steel tanks 9
Stainless steel passivation solution: (400 series stainless steel, which can pass 96-780 hours of standard salt spray test)
