  • Once stainless steel appears rust spot how to deal with?
    Jul 30, 2018

    There are mainly 2 methods to deal with the rust spot.

    1. chemical methods

    It is very important to use the pickling paste or spray to reactivate the chromium oxide film to reactivate the chromium oxide film to restore the corrosion resistance. After pickling, it is very important to remove all the pollutants and acid residue. After all the treatments are polished with polishing equipment and sealed with polished wax. For local slight rust, you can also use 1:1 gasoline and oil mixture to wipe rust spots with clean rag.

    2. mechanical method

    Sandblasting cleaning, glass or ceramic particles shot blasting, annihilation, scrubbing and polishing. By mechanical means, it is possible to wipe off the pollution caused by previously removed materials, polishing materials or annihilation materials. All kinds of pollution, especially foreign iron particles, may be the source of corrosion, especially in humid environments. Therefore, the mechanical cleaning surface should preferably be cleaned under dry conditions. The mechanical method can only clean up the surface, and can not change the corrosion resistance of the material itself. Therefore, it is suggested that after polishing the machine, the polishing equipment should be re polished and polished.
