There are many experiments to be done in the production process of stainless steel water cups, among which salt spray testing is very critical. Why do stainless steel water cups need to be tested in salt spray?
Salt spray test is an environmental experiment that mainly uses the artificial simulated salt spray environment state of salt spray testing equipment to evaluate the corrosion resistance of products or metal materials. So since it is a stainless steel water cup, does it not need to do this high-intensity salt spray test? No, stainless steel is at least a general term for a type of steel, but it seems that all stainless steel will not rot, and not all stainless steel can pass the salt spray test. Only stainless steel water cups that pass the salt spray test can become people’s daily needs for water cups. Even if they contain water with weak salinity or strong alkaline water, they are unlikely to corrode the water cup and harm health.
The purpose of the salt spray test is to evaluate the salt spray corrosion resistance quality of products or metal materials, and judging the results of the salt spray test is the judgment that determines the quality of the product. The correctness and reasonableness of its judgment results are the key to properly measure product quality or metal salt spray corrosion resistance.
As a product that must be used daily, water bottles often come into contact with our hands. Some consumers use water bottles during exercise. After exercise, the body will emit a lot of sweat, and the sweat contains salt. When it comes into contact with the stainless steel surface, the salt will remain. on the surface of the water glass. If the water cup fails to pass the salt spray test, the water cup will rust and cannot be used anymore. Therefore, some stainless steel water cups will be randomly inspected for salt spray testing before leaving the factory to ensure that they meet national quality requirements.
On the other hand, sometimes the environment where water bottles are stored and used is not always dry, and may be very humid for a period of time, such as the rainy season in the south. If there is some salt in the air and the environment is humid, substandard water cups can easily cause rust, so the salt spray test before leaving the factory is particularly important.
Therefore, stainless steel water cups, especially stainless steel water cups, must undergo a salt spray test. At the same time, when purchasing a stainless steel water cup, you can also check that the product has passed the salt spray test.
