Advantages of pickling passivation:
1. The products that have been pickled and passivated first improve the appearance of the product, and the color is uniform and uniform. 2. The product has good corrosion resistance.
3. Improve the service life of the product.
4. Extend anti-rust performance and grinding performance.
Stainless steel pickling passivation liquid is mainly a liquid designed for the surface treatment process, the product is mainly pickled and passivated into one, mainly for stainless steel pipes, pharmaceutical factory chemical pipelines and other surface treatment
1, the use of the product: pre-treatment is now the surface of the pipe stains and grease cleaned, 2, pickling passivation, the cleaned pipeline soaking or allowing the agent to enter the pipeline container method of use, the general purchase of soaking method and spraying two methods, soaking time is about 30 minutes, spraying time is extended, simple operation, the inner and outer surfaces after treatment are silvery-white, with good corrosion resistance, long-term use is not easy to change color and rust, at the same time can effectively improve the adhesion and wear resistance of the pipe surface, Extend the life of your pipes.
Stainless steel products are treated with oil stains and impurities on the surface before pickling and passivation, and the surface can achieve a bright effect after treatment.
Soak in the pickling passivation pool for 30-50 minutes, the winter time can be extended, according to the specific situation of the product surface, there are two ways of pickling and passivating stainless steel, one is the immersion method
The soaking method is to soak the product in the pickling passivation agent, and when the time comes, take it out and wash it with water, and there is a method called spray method: because the workpiece itself is relatively large, it needs to be sprayed, that is, the acid and alkali resistant circulation pump is used, and the spray device is installed at the outlet.
Cycle up and down.
It should be noted here that after pickling and passivation, neutralization treatment is required, and the neutralization solution ratio is diluted and soaked in 5% sodium hydroxide solution for 10 minutes.
