There are many experiments to be done in the production process of stainless steel water bottles, among which the salt spray test is very important. Why should the stainless steel water bottle be tested for salt spray?
Introduction to Salt Spray Test
The salt spray test is an environmental test that mainly uses the artificial simulated salt spray environment possessed by the salt spray test equipment to evaluate the corrosion resistance of products or metal materials. So since it is a stainless steel water bottle, is there no need to do such a high-intensity salt spray test? No, stainless steel is at least a general term for one 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 the stainless steel water bottles that pass the salt spray test can become people’s daily needs water bottles. Even if water with weak salinity or alkaline solid water is filled, it is impossible to corrode the water bottle and damage health.
Purpose of the Salt Spray Test
The purpose of the salt spray test is to evaluate the corrosion resistance of a product or metal material to salt spray. And judging the results of the salt spray test is the judgment that determines the quality of the product. The correctness and rationality of the judgment result is the key to properly measuring the product quality or the metal’s anti-salt spray corrosion performance.
Importance of the Salt Spray Testing
As a product that must be used in daily life, water bottles will often come into contact with our hands. Some consumers use water bottles during exercise. After exercise, the body will excrete a lot of sweat, and sweat contains salt. After touching the stainless steel surface, the salt will stay on the surface of the water glass. If the water bottle cannot pass the salt spray test, it will rust and can no longer be used, so the stainless steel water bottle will be sampled for the salt spray test before leaving the factory to ensure that it meets the national quality requirements.
On the other hand, sometimes the environment in which the water bottle is stored and used is not always dry, and it 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 in a humid environment, the water bottle that does not meet the standard will also easily cause rust, so the salt spray test before leaving the water bottle factory is particularly important.
Therefore, stainless steel must be subjected to a salt spray test, especially stainless steel water bottles. At the same time, when purchasing stainless steel water bottles, you can also check if the product has passed the salt spray test.
