1. Q.What is the salt spray test?
The salt spray test is an environmental test that uses artificial simulated salt spray environmental conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories, one is the natural environmental exposure test, and the other is the artificial accelerated simulated salt spray environment test. The artificial simulated salt spray environment test uses a test equipment with a certain volume space--the salt spray test chamber, and uses artificial methods in its volume space to cause the salt spray environment to evaluate the salt spray corrosion resistance quality of the product.
2. Q.What is the neutral salt spray test?
It is the most widely used accelerated corrosion test method in the earliest applications. In general, it uses a 5% aqueous solution of sodium chloride solution, and the pH of the solution is adjusted to a neutral range (6.5 to 7.2) as a solution for spraying. The test temperature is 35 °C, and the sedimentation rate of salt spray is required to be between 1~3ml/80cm2.h, and the settlement is generally between 1~2ml/80cm2.h.
3. Q.What is the acetate salt spray test?
It was developed on the basis of the neutral salt spray test. It is to add some glacial acetic acid to the 5% sodium chloride solution, the pH value of the solution is reduced to about 3, the solution becomes acidic, and the salt spray finally formed is also changed from neutral salt spray to acid. Its corrosion rate is about 3 times faster than the NSS test.
