Stainless Passivation Process Introduction
The stainless steel passivation liquid adopts the latest catalytic technology, so the passivation speed of the improved product is faster and the corrosion resistance is stronger than before. Through the passivation of this product, a dense passivation film can be formed at 5-15min, while maintaining the original gloss of the work piece without damage to the work piece size, and the performance of the neutral salt fog can be increased by 10-30 times.

All are passivated for added protection against oxidation and corrosion. A Torx drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess. For Torx tools, see Torx and Torx-Plus bits, keys, and drivers. Length is measured from under the head.
1.Operate under normal temperature, short passivation time: save energy effectively and improve efficacy;
2.No contain heavy metals: environment friendly;
3.Good stability: normal service life can reach more than one year;
4.Good salt fog performance: above 1500H.
Consumption Estimate
For cleaning of general stainless steel welding line and argon arc welding line, it needs about 0.5kg every one hundred meters;
For cleaning of arc welding line, it needs about 1kg every one hundred meters;
For cleanup thick oxide on heat press end socket or heat treatment part, it needs about 1kg every two sq.m...
Technological Process
Degreasing --- Rinsing water --- Pickling --- Rinsing water --- Passivation --- Rinsing with running water--- Neutralizing --- Rinsing --- Cleaning with pure water --- Drying
Instructions
1.For cleaning of welding line oxide, first clean welding residue welding line and oily soil, then paint grease on the pretreated surface with the coating thickness is 1~2mm and resort about 1~2hours is needed, at last clean residues on the cleaning surface with cotton waste or rug (water washing is better) until bright and clean.
