During the process of selection, the filter bag will effectively determine the filtration mode (deep filtration, surface filtration) to a certain extent according to the actual requirements of the filtration process, and then determine the filter bag material, according to the filtration flow rate, medium viscosity, The three factors of filtration accuracy determine the size of the filter bag.
Bag filter The filter materials of different materials have different filtering methods, filtration efficiency and filtration accuracy. Even if the same filter material is used, the temperature, viscosity, flow rate or filtrate quality and impurity content of the filtrate will change. When the filter effect changes, please select the most suitable filter material according to the actual working conditions.
The filter bags are used in many types and materials, and different filtrates also have different physical and chemical properties. In the filtration process, the filter media must be compatible with it. It cannot react chemically. The filter media must also face the same pressure and temperature change as the filtrate. The filter media must maintain its fixed structure and the pore size does not change. Softening, cracking or release of ingredients can provide stable, uniform filtration quality.
Under normal circumstances, the filtration of acid and cesium salts and other relatively high-polarity filtrate can be directly selected during the use of its PP material filter, filter solvents and other relatively low-polarity filtrate, select PE or NY material The filter material.
The bag filter bag has the outstanding features of economical application of filter consumables, low filter pressure drop, and more convenient operation, and is suitable for most conventional precision filtering applications. The filter bag is the core of the LD series bag filter system and directly determines the filtration performance and the quality of the final product.
Filter bags with different characteristics can meet strict precision filtration requirements. Bag filter bag has excellent chemical stability and heat resistance, is the representative of the highest performance in the filter material industry, and is also the most high-end variety of all commonly used filter materials, in terms of filtration efficiency and filtration accuracy. Reach a higher level. The commonly used filter media are PE, PP, PTFE, PMIA, NMO and so on.
