The salt spray test chamber is used for salt spray corrosion test, and its material has been used in three industries. PVC board, PP board and glass steel.
Reinforced plastic, or glass reinforced plastic, made of glass fiber or its products as a reinforcing material. It takes a long time to fade the surface of the fiber. And the FRP is fragile and cumbersome. FRP uses the bottom heating wire spacer to dry the heating method to provide heat to the box. This method is more primitive and easy to age the box and reduce the service life. It has already been eliminated by the salt spray test box industry.
PVC (polyvinyl chloride) is a polymer material and is a saturated polymer with chlorine. Therefore, it is chemically stable, free from acid and alkali corrosion, salt corrosion, and strong in oxidation resistance. It is used in the manufacture of salt spray test chambers. It is self-resistant to salt spray corrosion. It has a unique molecular structure, which makes it good in formability, flexibility, and easy to process (simple welding can be used), which makes the manufactured products look beautiful. However, many customers now need to do acid salt spray test and copper accelerated vinegar instinct test (ie CASS test), however PVC material is suitable for neutral salt spray test, not suitable for acid salt spray. Long-term acid testing will deform and soften the salt spray test chamber.
At present, the most widely used material for users is PVC board. It can meet the general salt spray test. And the price is not high. Users without special requirements will generally choose the material of the PVC board.
The PP board is more resistant to high temperatures and corrosion resistance than the PVC board. If the acid salt spray test is carried out for a long time, the salt spray test box of PP plate material is the best choice. It is not easily deformed and softened. However, the price of PP board and PVC board is different compared to PVC board material.
