Stainless Steel Pickling and Passivation Solution

ZX-610 Stainless Steel Pickling Passivation Solution

I: Stainless Steel Pickling Passivation Solution is suitable for: 300 series stainless steel (301, 302, 303, 304, 316, 316L, 400, 410, 416 series, etc.) surface pickling and passivation treatment.

II: Stainless Steel Pickling Passivation Solution is applicable to: petrochemicals, marine pipelines, pharmaceuticals, papermaking, food, Class I-III pressure vessels, and related stainless steel components. It removes brown oxides (rust) generated after high-temperature processing such as welding, hammering, and impact damage, restoring a silver-bright luster while forming an oxide layer to achieve passivation. It combines the dual functions of pickling and passivation in one step.

III: Physical characteristics of Stainless Steel Pickling Passivation Solution: no fumes, low odor, operable both indoors and outdoors. Suitable for brushing, spraying, and soaking, with soaking being the most effective. The operation process is simple, construction is convenient, saving time and effort. The treated stainless steel surface is smooth and clean, with enhanced stability, significantly improved corrosion resistance, extended equipment service life, and increased product added value.

IV: Usage method of Stainless Steel Pickling Passivation Solution: Small stainless steel parts can be soaked in containers using the original solution. Recommended soaking time is 10–20 minutes in summer and 30–50 minutes in winter. Users can adjust the time based on the desired color intensity.
Each kilogram of passivation solution can treat a surface area of 60–70 square meters without loss of chemical composition. (If the oxide layer is thick or there is heavy soiling, extend the soaking time appropriately.) Rinse thoroughly with clean water. For larger equipment, to ensure cleaning and passivation quality while saving material, use a pump for cyclic spraying. (Note: Final rinsing with clean water must be thorough to ensure no residual pickling passivation solution remains.) The treated stainless steel surface will be as clean as new, restoring its original appearance.

V: Precautions for Stainless Steel Pickling Passivation Solution:
1. Cleaning tank: Use acid-resistant plastic tanks, fiberglass tanks, or low-carbon steel tanks with PVC plastic lining.
2. Tank solution addition and maintenance: Regularly remove debris and residues from the tank (to prevent them from reducing the solution concentration). When the working solution’s cleaning capacity declines, replenish with new solution to restore effectiveness (pH should be controlled below 2; when pH exceeds 2, promptly add some new solution).
3. Remove sediment and floating matter from waste liquid, then add new solution for adjustment to continue use, or adjust pH, separate sediment, and discharge waste liquid according to environmental standards.
4. Wear rubber gloves, goggles, and other protective equipment during operation; avoid skin contact with the product. In case of accidental contact, rinse with water.
