Stainless steel type 201 has a low nickel content. When it is corroded with corrosive liquids containing ferric chloride, it will leave a layer of black ash like oil on the corroded surface. The ash is difficult to remove on the hands and stains on the clothes. This layer of black ash appears because several materials contained in this material can only be separated from the body by the corrosive liquid and cannot be dissolved. Our factory maintains close cooperation with many domestic chemical research institutes and is familiar with market trends. The production line of the etching machine can solve the problem of blackening of the surface of the stainless steel 200 series (LH) etching process, and is completely solved.
Practice is the only standard for testing truth. The following picture shows the etching line of stainless steel decorative board. The effective feeding width is 1.3 meters, the effective etching area is 9 meters, the total length of equipment is 36 meters. The process flow: entering the board frame → 9 meters etching →Cleaning→Whitening→Cleaning→Inspection→Release→Neutralization→Washing and Drying→Pressing Plate→Double Sticking Machine→Outlet Plate→Packing
