The new type of acid-proof plate is a kind of composite plate with high efficiency and corrosion resistance introduced from the United States. Its 323/HC197-HST103 high temperature resin as the main material,MC quality series of glass fiber as the reinforcing material, Werprot L-48U weather-resistant coating and Melinex 301 film as the surface protection layer, imported color paste as the resin colorant, in 180 degrees Celsius high temperature forming. Its mechanical properties, chemical stability, corrosion resistance, is the ordinary FRP similar pressure plate is difficult to match. It is resistant to acid, alkali, salt and water vapor.
