Practical performance of stainless steel pickling passivation paste

2018/07/06

1: Stainless steel pickling passivation paste is suitable for: 300 series stainless steel (301, 302, 303, 304, 316, 316L, 400, 410, 416 series and other models of stainless steel surface pickling passivation treatment.
Two: Stainless steel pickling passivation paste products are suitable for: stainless steel components such as petrochemical, marine pipelines, pharmaceuticals, papermaking, food, class Ⅰ-Ⅲ pressure vessels, etc., which are produced after high temperature processing such as welding, hammering, bumping, etc. The removal of tan oxide (rust) makes the silver bright and shiny, and at the same time forms an oxide film to achieve passivation. It has the dual effect of two steps of pickling and passivation.
Three: stainless steel pickling passivation paste physical characteristics: no smoke, no odor, can be operated indoors and outdoors. Brushing, spray washing and soaking are all available, soaking is best. The operation process is simple, the construction is convenient, and the time and labor is saved. The surface of the stainless steel treated with the stainless steel pickling passivation paste is smooth and smooth, the stability is strong, the corrosion resistance is significantly improved, the equipment life is extended, and the added value of the product is increased.
Four: stainless steel pickling passivation paste use method: stainless steel small parts can be immersed in a container, the original solution is used, the recommended immersion time is 10-20 minutes in summer, 30-50 minutes in winter, users can choose their own time according to the color level Take control.
Per kilogram of passivation solution will not lose the composition of the medicinal solution within the processing surface area of 60 ~ 70 square meters. (If the oxide layer is thick and the dirt is large, the time can be appropriately extended.) Rinse with clean water. For larger volumes, In order to ensure the quality of cleaning and passivation and save the passivation materials, the equipment can be treated by circulating spraying with a pump. (Note: The final rinse with clean water must be clean and thorough to ensure no residual acid pickling passivation paste). The surface of the treated stainless steel equipment is as smooth as new, and the original color of the stainless steel is restored.
5: Stainless steel pickling passivation paste matters needing attention:
1. Cleaning tank: The working tank is made of acid-resistant plastic tank, glass fiber reinforced plastic tank, and low carbon steel. PVC plastic lining is required.
2. Addition and maintenance of tank liquid: regularly clean up the debris and residues in the tank (to prevent debris and residues from reducing the concentration of the tank fluid). When the cleaning ability of the working fluid decreases, it can be resumed by adding new fluid (the pH value should be controlled within 2; when the pH value is greater than 2, some new fluid should be added in time).
3.Remove the sediment and floating matter from the waste liquid, then add new liquid to adjust and continue to use, or adjust the PH value, separate the sediment, and discharge the waste liquid according to environmental standards.
4. Protective equipment such as rubber gloves and goggles should be equipped during operation; the skin should not be in contact with stainless steel pickling and passivation paste, and should be washed with water by accident.
