Stainless Steel Pickling And Passivation Liquid Anti Simple Operation And Convenient Construction

Stainless Steel Pickling and Passivation Liquid Anti Pickling passivation solution ZJ-302-2 is the latest research and development technology, the product is suitable for all 200 series, 400 series of stainless steel, the product pickling passivation pass, you can stainless steel 200,400 series of surface into Uniform silver white smooth surface, the rapid removal of stainless steel welding spot oxide, rust and other metal oxides, washed 200,400 series of stainless steel surface silver white light, not black, instead of peeling with the use of liquid and surface black phenomenon. The product is Zhijian special patented product, is a domestic technology, for enterprises to save costs

    product advantages

1,Stainless Steel Pickling and Passivation Liquid Anti this product is used for stainless steel welded joints and surface pickling passivation, removal of welding, high temperature processing after the production of oxide scale, so that silver bright light, and the surface after treatment to form a layer of chromium as the main Material oxide film, will no longer produce secondary oxygen corrosion, to pass the purpose of passivation, thereby enhancing the surface of stainless steel products, anti-corrosion quality, extend equipment life. Rust and passivation effect of more than similar foreign products, reached the international advanced level.

2,Stainless Steel Pickling and Passivation Liquid Anti the goods will pickling and passivation simultaneously, one step to complete, changing the traditional pickling and passivation process, simple operation, easy construction, low cost.

3,Stainless Steel Pickling and Passivation Liquid Anti the use of this product does not require specialized equipment and venues, do not need heating equipment and power supply, do not need skilled operation of workers, labor, time, energy saving.

4,Stainless Steel Pickling and Passivation Liquid Anti the product is a stable liquid and paste, it does not decompose, do not precipitate, easy to transport and long-term preservation, with the use of easy to take.

The effect of the passivation solution

 Can effectively improve the corrosion resistance of stainless steel to extend the service life of the workpiece.

1, to improve the adhesion of the passivation film. Silica is added to the passivation solution to form a colloidal solution. After applying to the galvanized sheet and dried, the passivation solution is cured into a gel and has a strong adhesion to the galvanized sheet. The following are the same as the "

2, to maintain hexavalent chromium. Silica can agglomerate hexavalent chromium in its gel, delaying the rate of hexavalent chromium loss and prolonging the time it takes for self-healing.

3, play a supplementary anti-corrosion effect. Silica gel formed by the gel itself has a certain degree of isolation to prevent the external moisture and gas into the galvanized layer surface, play a role in auxiliary anti-corrosion. The following are the same as the "

4, to improve the product coating performance. Silica is present in the gel as polar particles, so that it can also act as a medium in addition to the other components of the passivation layer adsorbed on the surface of the galvanized sheet and can be coated with the passivation layer Layer tightly combined, change the passivation of the galvanized sheet can not be painted the lack of coating,Stainless Steel Pickling and Passivation Liquid Anti so that after the passivation of the galvanized sheet can not only continue to paint, and coating performance better. In fact, the addition of silica after the passivation solution is closer to the composition of the color coat pretreatment liquid. So passivated products can be used directly, but also as a color coated substrate.

5, to improve the fingerprint resistance of the product. After adding silica, the role of silica gel after the passivation of the product surface passivation film is more uniform, forming a very light very uniform light yellow, even if the amount of fingerprint adsorption is not easy to be perceived, so in general In the case of visual inspection, the fingerprint resistance of the product is improved.

6, silica and phosphoric acid play a complementary role. The role of silica and phosphoric acid should be said to be the opposite, the silica is polar, phosphoric acid is non-polar, phosphoric acid is a reactive type of additives, silica is attached to the additive. But the two are not mutually exclusive,Stainless Steel Pickling and Passivation Liquid Anti will not weaken the other side of the role, but learn from each other. The combination of the results of the product appearance, corrosion resistance, coating are at a better level, one of the two are better than the use of both.
