The characteristics of FRP membrane shell are as follows
1. Excellent and reliable internal quality
The FRP membrane shell is manufactured by a computer program-controlled winding unit and high-performance processing equipment. The main materials are epoxy resin and fiber. After special processing, the FRP membrane shell has a high degree of pressure resistance, temperature resistance and corrosion resistance. To achieve the incomparable advantages of ordinary steel, plastic and other materials.
2. Excellent insulation properties
The thermal conductivity of the glass fiber reinforced plastic film shell at room temperature is generally in the range of 0.15-1.36W (m.k), which is only about 1/200. Its thermal insulation performance is unmatched by metal materials. This feature is very beneficial to the reverse osmosis membrane in the membrane shell, and plays a role that the outside temperature has little effect on the membrane.
3. Outstanding corrosion resistance
The combination ratio of glass fiber and epoxy resin has been specially cured to form a natural corrosion-resistant product. The inner surface is smooth and the coating has good stability to solvents such as acids, alkalis, salts, and oils with low concentrations. The seawater and microorganisms entering the shell are effectively inhibited, and there is no corrosion in long-term use.
4. Structural design
The barrel body, head and slot of the membrane shell have undergone strict layup design and optimized calculation details to ensure structural safety. The optimized design of the concentrated water side opening can meet the necessary safety pressure of four side openings on one head, and enhance the variability in the installation process.
5. Reliability of components
The end plate is an important part of the membrane shell assembly, which has high strength, excellent pressure resistance and high pressure impact resistance. The sealing design is a professionally designed "V+X" ring with an O-type end plate sealing ring to ensure that it is watertight under low and high temperature ranges. The sealing design of the side opening is a combination of L-shaped bulging and circular pads, which ensures that the side opening mouth can play a better sealing effect in the case of angle deviation. The side opening is fastened with a lift-up female fastening, making it more adjustable.
The above is the introduction of the characteristics of the FRP membrane shell. In addition, the membrane shell, as the outer shell of the filter element, can be used continuously for a long time, but in order to ensure the long-term and efficient use of the membrane shell, please strictly follow the product's acceptable operating temperature range (-7c-49c), and it is strictly forbidden to exceed this temperature range. work under conditions.
