Salt Spray Tester

 

Salt spray corrosion test box through the assessment of the material and its protective layer of salt spray corrosion, and similar protective layer of the process of quality comparison, at the same time can assess the ability of certain products salt spray corrosion; The product is suitable for parts, electronics Components, metal materials, protective coatings and industrial products, salt spray corrosion test.

 

Salt spray chamber is the use of salt spray corrosion test samples were tested for the reliability of corrosion resistance, salt spray is the atmosphere composed of tiny droplets of salt formed by the dispersion system is artificial environment three anti-series A lot of business products need to simulate the destructive effects of the climate around the sea, so salt spray chamber should go its route. Salt spray test is divided into two kinds of neutral salt spray and acid salt spray, the difference is in line with the standards and test methods are different, respectively, "NSS" and "CASS" test, artificial three weather climate is the most common test method.

 

Salt spray corrosion

Corrosion is the destruction or deterioration of the material or its properties caused by the environment. Most of the corrosion occurs in the atmosphere, the atmosphere contains oxygen, humidity, temperature changes and pollutants and other corrosion components and corrosion factors. Salt spray corrosion is a common and most damaging atmospheric corrosion. Salt spray here refers to the atmosphere of the chloride, its main component of corrosion is the chloride salt in the ocean - sodium chloride, it is mainly derived from the marine and saline areas. Salt spray corrosion of the metal surface is due to the chloride ions contained in the metal surface through the oxide layer and the protective layer and the internal metal electrochemical reaction. At the same time, chloride ion contains a certain amount of hydration energy, easily adsorbed in the metal surface pores, cracks displace and replace oxygen in the oxide layer, the insoluble oxide into a soluble chloride, the passive state of the surface into a lively surface . Caused a bad product adverse reactions.
