The salt spray test chamber is mainly used to test the stability of the product in the salt spray environment, because whether it is a metal product or a non-metal product, the natural air contains moisture and salt (inorganic salts, etc.), causing corrosion, resulting in performance changes. Such as metal corrosion, circuit board corrosion, etc.
Due to the corrosive nature of the salt spray corrosion test chamber itself, the outer shell of the salt spray corrosion chamber cannot be made of metal materials or materials susceptible to salt spray corrosion. At present, the main materials are epoxy resin (commonly known as FRP) and rigid PVC.
FRP is made of high hardness, but it is brittle and can withstand high temperature, but it has long-term temperature resistance. The salt spray corrosion test box is made of thin plate, which results in short service life, easy damage and poor aging resistance, but low cost. Most of the early manufacturers used FRP as the outer casing.
PVC material has good chemical stability, is not affected by salt spray, has good material elasticity, good flexibility and excellent aging resistance, so it has a long service life, but it is costly relative to FRP, which is increasingly competitive and profitable. In the thinner salt spray test box industry, although there are new processes and materials to replace the old process and materials, but many factors are considered to consider the cost.
For the user, I recommend that you use the salt spray corrosion test chamber of the PVC casing because of its long service life and low maintenance cost.
Letting customers choose and use the best products is the principle that Lihui has always been seeking. Lihui will work with customers and peers to contribute to the development of the entire environmental testing equipment industry.
