OY-11 stainless steel black cleaner industrial production, in the case of stainless steel is generally easy to generate a high temperature black oxide, and quite dense and difficult to remove by conventional methods, the use of the product to soak for 10-30 minutes, the stainless steel surface can black oxide softening effect while cleaning achieve qualities of stainless steel, get white surface, but do not stay dead, color white, with good decorative. And the product also has oil-cleaning effect. First, the process: two, OY-29 at room temperature degreasing → OY-11 in addition to black handle → three countercurrent water rinse → OY-122 ultrasonic cleaning (with severe residual black increases this procedure) → three countercurrent water rinse Second, use: After OY-29 after crude oil, use a plastic tank, liquid is added directly, or add about 40% by volume of the trough OY-11 stainless steel black cleaners, then add the same amount of hydrogen peroxide (concentration requires 35-50%), 1: 1 after a good preparation to have black (scale) of stainless steel products on the work soaking liquid at room temperature for 10-30 minutes, if minor scale direct water to clean out white surface can be obtained, if there is a serious black residue that can increase an OY-122 ultrasonic cleaning. Third, pay attention: If black is relatively modest, you can join another 1-3 parts water use, the specific processing time in the practical application of the standard, the product has some oxidation, have a certain effect on the skin, please note that when you work with a good labor supplies. Fourth, the product packaging: 25 kg / barrel.
