Advantages and disadvantages of different materials of salt spray aging test chamber

The salt spray aging test chamber is used to evaluate the salt spray corrosion capacity of materials and protective layers. At first, the equipment material consisted of plastic plates reinforced with fiberglass. Soon this material was disposed of and then used. The most popular is PVC reinforced hard plastic board, and now most manufacturers use PP board. So, what are the advantages and disadvantages of these three different materials?
Fiberglass Reinforced Plastic Salt Spray Aging Test Chamber: The reinforced plastics that use fiberglass or its products as Reinforcement materials are called fiberglass reinforced plastics. Or called fiberglass. Over time, the surface easily discolors and becomes fibrous.
Ref hard plastic salt spray aging test chamberPVC orated: It has the advantage of being relatively resistant to corrosion and can be used for neutral salt spray testing and general salt spray testing. But as testing requirements become more stringent. M.All customers should conduct Acid Salt Spray Test and Copper Vinegar Accelerated Performance Test (i.e. CASS test) and require manufacturers to make corrections, but the cost of this method is too high.
Salt Spray Aging Test Chamber for PP Boards: PP boards can withstand higher temperatures than PVC boards. PVC salt spray: cabinet temperature is 35℃, air-saturated barrel is 47℃; PP board salt spray: cabinet temperature is 50℃, air saturated barrel is 63℃. If the above-mentioned materials are used for salt spray testingacidic, the test chamber body will deform over time. But the materials mentioned later will not, because they have the advantage of a wider test range and their price is also slightly different.
