Performance characteristics about FRP pressure vessels(membrane housing )
1.Reliable intrinsic quality
The main material is epoxy resin and fiber material, which are processed by special technology. The finished product has the advantage of high pressure, high temperature and corrosion resistance, which is incomparable with ordinary steel, plastic and other materials.
2.Folding excellent insulation performance
FRP diaphragm. At room temperature, the thermal conductivity is generally in the range of 0.15-1.36W (m.k), about 1/200. Its adiabatic performance is incomparable with metallic materials. This characteristic is of great benefit to the reverse osmosis membrane in the membrane shell, and has little effect on the external temperature.
3.Folding prominent corrosion resistance
The combination ratio of glass fiber and epoxy resin is specially cured to form a natural anti-corrosion product. The inner surface is smooth and the coating has good stability to low concentration of acid, alkali, salt, oil and other solvents. The seawater and microorganisms in the shell can be effectively suppressed. Long term use is not corrosive.
