The salt spray corrosion test box is used for salt spray corrosion test as its name implies. This test box has been updated three times in terms of the commonly used one.
FRP material: FRP scientific name "glass fiber reinforced plastic", because its strength is equivalent to steel, and contains glass components, it also has the color, shape, corrosion resistance, electrical insulation, thermal insulation and other properties of glass. Like glass, historically This easy-to-understand name "FRP" was formed.
PVC board material:
1) Hardness PVC board: The quality of the product is implemented in GB / T4454-1996, which has good chemical stability, corrosion resistance, high hardness, high strength, high strength, UV protection (aging resistance), fire retardant (self-extinguishing Property), reliable insulation performance, smooth and smooth surface, no water absorption, no deformation, easy processing and other characteristics.
2) PVC transparent board: This product is a kind of high-strength, high-transparent plastic sheet produced by China's introduction of foreign advanced technology and selection of advanced imported raw materials.
PP board material: The scientific name "polypropylene board" has the characteristics of light weight, uniform thickness, smooth and smooth surface, good heat resistance, high mechanical strength, excellent chemical stability and electrical insulation, non-toxic and so on. PP board is widely used in chemical containers, machinery, electronics, electrical appliances, food packaging, medicine, decoration and water treatment. The practical temperature of PP board can reach 100 degrees.
When using PVC board material for the salt spray corrosion test box, the box body is made of PVC hard plastic board, and the box cover is made of transparent PVC board. At present, most of the materials used in China are PVC board and PP board, and the fiberglass material has been eliminated a few years ago.
