PVDF pleated filter element encyclopedia

PVDF folded filter element is a kind of folded filter element that is rarely touched. I believe that everyone is relatively unfamiliar with it. Today, Su Senyuan will introduce some relevant instructions of PVDF folded filter element. Definition: PVDF pleated filter element is also called polyvinylidene fluoride pleated filter element. The filter material of PVDF polyvinylidene fluoride pleated filter element is polyvinylidene fluoride microporous membrane. , The casting liquid composed of porogenic additives is coated on polyester non-woven fabrics on both sides, and is prepared by phase inversion method. Advantages: This kind of filter element has good heat resistance and chemical stability, can withstand high pressure steam sterilization less than 138 ℃; can withstand strong acids, aliphatics, aromatics, ketones, ethers and other organic and inorganic solvents. The two sides of the membrane are completely covered, no fibers are exposed, the surface pores are densely distributed, the pore shapes are round and oval, the pore size of the positive and negative pores is the same, and the pore size distribution is narrow. The membrane has strong negative electrostatic properties and hydrophobicity. It is a new type of precision filter medium that can be used for liquid sterilization, particle removal, and gas dehumidification, dust removal, and sterilization filtration. Ideal material for separation of downstream products of bioengineering. Features: Large filtration area, high throughput, small energy loss, good corrosion resistance to chemicals, suitable for filtration and hot-melt process welding of solvents and acids and other solutions Industrial product specifications: length: 5-40 inches Filtration accuracy: liquid 0.1m; 0.22m; 0.45m; gas 0.01m; bacteria removal rate: 99.9999%; filtration area: ≥0.60m2; allowable working pressure difference: ≤0.40 MPa, 25℃; Allowable working back pressure difference: ≤0.30MPa, 25℃; Working temperature: ≤90℃, 0.15MPa; Maximum disinfection temperature: 138℃, 0.275MPa; Sterilization temperature: 121℃, 30min Application: various High-precision filtration of oil, purification and filtration of chemical raw materials, purification and filtration of high-temperature liquids, purification and filtration of various air, steam and compressed air
