Methods for rust removal and rust prevention on the stainless steel surface of equipment
Thread Content
In medical and chemical enterprises, air-induced corrosion is difficult to avoid; rust appears on the surfaces of stainless steel equipment. As a routine solution, sandpaper is used for manual treatment, but rust reappears after just a few days due to oxidation. Sometimes varnish is applied to stainless steel flanges to prevent rust, but this makes the equipment look unsightly. What methods are generally used to prevent rust? I’m referring to the highly polished surface of stainless steel. After researching various anti-rust methods, I found that pickling is more suitable for use on surfaces with rough textures such as tanks, as otherwise it can cause whitening and an unsightly appearance. If anti-rust treatment is needed on the surface of equipment (which is usually highly polished or made of stainless steel sheets), should anti-rust greases be used? After use, considerations include the odor, its impact on clean spaces, whether it tends to peel off, whether the surface becomes uneven and unsightly, whether an oily layer forms on the surface that can be easily wiped away, or any other effects on appearance or usability. Those who have used it please share their experiences. In practice, it seems that the anti-corrosion measures implemented by various companies are not very effective. . . Hehe, in our practical work, we do implement anti-corrosion measures. What other tasks can help save costs significantly? Please give some advice
I. Strengthen the protection of stainless steel equipment to prevent it from coming into contact with carbon steel； II. The equipment should be made from stainless steel plates with a low carbon content; many domestically produced stainless steel plates have a relatively high carbon content. If such plates are not available in the domestic market, it is recommended to use high-quality imported stainless steel plates for manufacturing the equipment.
Using an anti-corrosion paint with a high level of corrosion resistance is also an option
What I need are specific treatment methods; the stainless steel surface should ideally maintain a mirror-like finish that meets food hygiene standards. Is paint applied on top transparent and free from contaminants?
After rust removal from the surface, try using a passivation paste. Also, if stainless steel rusts frequently, it means you have chosen the wrong material or purchased inferior quality material.
The donor on the sixth floor is right; it’s better to use a cloth wheel for mechanical polishing first before applying the passivation paste.
Stainless steel rust removal and rust prevention – Regarding the issue of rust formation in stainless steel: 1. Whether stainless steel rusts or not is directly related to the material itself, the environment, and the way it is used. For common materials such as 201 and 304, it is normal for them to rust, and this is directly related to the properties of the material. 316 can also rust, but only under specific conditions. Therefore, our focus should be on rust prevention； 2. To prevent rust, it is first necessary to ensure a smooth surface of the material. I work in the field of surface treatment products, and seeing everyone troubled by rust, I would like to offer some solutions; I can also send samples to you free of charge for testing ； Usage: Dilute the stainless steel brightener (which helps remove surface stains and rust) 4 times, then scrub the surface repeatedly with a towel until all the rust is gone. Wash it clean with hot water, let it dry, and spray on rust preventive solution to maintain a smooth surface for over 6 months ； We offer it for free to friends in urgent need to try it out ； Deng Sheng 13924846536 www.chinashewu.com
Hehe, thanks to the friend above. I’ve found a stainless steel spray from the 70-56 series; it’s said that after using it, the surface can be restored to a polished stainless steel state. The price is around 300 yuan for 400ML. There’s also a type of care solution designed to prevent rust on polished surfaces. I wonder if any of you have used similar products? How effective is it?
There are some issues with your selection of stainless steel material!
It’s a material issue; it shouldn’t rust. It can be pickled and passivated.
