1.Product Introduction
By the appropriate use of DY - 3 of membrane material, has good mechanical strength and toughness, not corroded at room temperature by acid, alkali, strong oxidizing agents and halogen corrosion, and is stable for fat hydrocarbon, aromatic hydrocarbon, alcohol, aldehyde and organic solvent, in hydrochloric-acid,nitric-acid,sulfuric acid and dilute, the strong alkali liquor (40%), and as high as 100 degrees Celsius temperature, its performance is basically unchanged, and resistant to gamma ray, ultraviolet radiation, in a wide temperature range can be used for a long time and basically maintain its performance.
2.Advantages
PVDF hollow fiber ultrafiltration membrane no energy consumption, green environmental protection, can filter out all bacteria, viruses, turbidity, spores, giardia and rust and other substances, but can retain the characteristics of essential trace elements of the human body.
