Which One is More Better Compared with Pickling Passivation Paste and Rust Remover when Cleaning Rust Stain?

Rust marks on stainless steel can be divided into two types, one is produced by impurities attached to the surface;The other is true material rusting.So which one need to be used to clean traces of corrosion? pickling passivation paste or rust remover?

It is necessary to mention the difference between the stainless steel pickling passivation paste and the rust remover.The rust remover usually can only remove the rust of the metal surface, and there is no passivation function.This kind of derusting is short-lived, and it will also rust.

In other words,the production of a large amount of hydrogen during the treatment of rust will cause hydrogen embrittlement of the steel, which will cause the mechanical properties of the metal to decrease and affect the strength of the steel itself;At the same time, it is easy to form acid fog, which affects the health of operators,the equipment and environment around them;The consumption of acid is also high, increased processing cost;This type of acid will cause excessive corrosion of the steel.

But stainless steel pickling passivation paste is different, it can realize stainless steel pickling passivation combined.At the same time, high efficiency corrosion inhibitor is added to prevent the occurrence of corrosion and hydrogen embrittlement of metal, which is a kind of two-component material.

In the process of using, not only the reaction speed is fast, the clearance is thorough, the viscosity is moderate, easy to observe, no corrosion to the substrate;Moreover, it does not contain the ions such as CL,P which damages the surface of stainless steel. The coating area is about 3 square meters per kilogram, and the film thickness is 1-2mm.

In addition, after the passivation of stainless steel pickling passivating paste, the corrosion resistance is 15 to 50 times, and the highest has been tested by salt mist 1500H.In summary, stainless steel pickling passivation paste is better than rust remover.It is the first choice of stainless steel industry.
