First, the reason for stainless steel valve rust

To test whether the stainless steel valve can rust, you can first verify the comparison by placing the same valve in different environments. Generally speaking, if the stainless steel valve is placed in a relatively dry environment, after a long time, the valve is not only as good as new. And there is no rust, but if the valve is placed in seawater containing a large amount of salt, it will rust in a few days. It can be seen that the corrosion resistance and rust resistance of the stainless steel valve also need to be limited by the use environment. In addition, from the characteristics of the stainless steel valve itself, it is stainless because it has a chromium-rich oxide film on its surface to prevent the particles such as oxygen atoms from invading the object, thus making it have stainless characteristics. However, when the film is destroyed by environmental factors and the like, the stainless steel valve will generate rust as the oxygen atoms enter and the iron ions are released.

There are many reasons for rusting the surface film of stainless steel valves. Some of them have electrochemical reactions with particles or dust of other metal elements. At the same time, they use wet air as a medium to form a micro-battery cycle, which makes the surface of stainless steel rust. The stainless steel surface film is directly exposed to corrosive liquids such as strong acid and alkali, causing corrosion, etc. Therefore, if the stainless steel valve does not rust, it is necessary to pay attention to the cleaning of the object in daily use and keep the surface of the valve clean.

Second, stainless steel valve rust solution

So how to ensure that the metal surface is always bright and not rusted? The professional technicians of Sanjing Valve Manufacturing Co., Ltd. suggest:

1. The decorative stainless steel surface must be cleaned and scrubbed frequently to remove the deposits and eliminate external factors that cause modification.

2. 316 stainless steel is used in the coastal area, and 316 is resistant to seawater corrosion.

3. Some stainless steel tube chemical components on the market cannot meet the corresponding national standards and cannot meet the 304 material requirements. Therefore, it will also cause rust, which requires the user to carefully select the product construction and construction points of the reputable manufacturer in order to prevent scratches and contaminant adhesion during construction, and stainless steel construction under the film state. However, as time goes by, the residue of the paste is in accordance with the expiration date of the film. When the film is removed after construction, the surface should be washed, and special stainless steel tools should be used. When cleaning the utility tool with ordinary steel, it should be cleaned in order to prevent the iron filings from sticking. . Care should be taken not to allow the highly corrosive magnetic and stone-cleaning drugs to come into contact with the stainless steel surface and to wash immediately if contacted. After the construction is completed, apply neutral detergent and water to wash the cement, ash, etc. attached to the surface.
