Know more about salt spray corrosion test chamber

Salt spray test is a kind of environmental corrosion test which mainly uses artificially simulated salt spraying environmental condition created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. Some metal products need to be tested by salt spray test, such as wire rope, high zinc wire, steel plate and so on.

Corrosion is the destruction or deterioration of the material or its properties under the action of the environment. Salt spray corrosion is a common and most destructive atmospheric corrosion. Salt spray refers to the atmosphere of chloride, its main corrosion component is chloride salt, sodium chloride in the sea, it is mainly from the sea and the inland saline-alkali area.

The corrosion of salt spray on the surface of metal material is caused by the electrochemical reaction of chloride ion through the oxide layer and protective layer on the metal surface. At the same time, chloride ion contains a certain amount of hydration energy, which is easy to be adsorbed on the pores of the metal surface, fracture extrusion and replace the oxygen in the oxide layer, turn the insoluble oxide into soluble chloride, and make the passivation surface become active surface,which causes extremely bad adverse reactions to the product.

Salt mist is a dispersion system composed of tiny droplets containing salt in the atmosphere.. Many enterprise products need to simulate the damage caused by the salt cossorion to the products.

Salt spray test is divided into:
Neutral Salt Spray Test (NSS)

Acetic Acid Salt Spray Test (AASS)

Copper Accelerated Acetic Acid Salt Spray Test (CASS)

Note: If you also need a cyclic salt spay chamber (including, salt spray, dry, humidify, high or low temperature function), please inquiry for a cyclic salt spray chamber.
