Liquid filtration membrane nonwoven fabric
Liquid filtration membrane nonwoven fabric, three-layer composite liquid filtration nonwoven fabric (support layer + membrane + protective layer), high dirt holding capacity liquid filtration membrane nonwoven fabric, long lifespan, biopharmaceutical sterilization filtration membrane nonwoven fabric, no heat source.
Product description
Liquid filtration membrane-coated nonwoven fabric: By coating the surface of the nonwoven fabric base with a membrane, bacterial impurities are reduced from penetrating the membrane and contaminating the nonwoven fabric base, increasing product lifespan and significantly improving filtration efficiency.
Liquid filtration membrane-coated nonwoven fabric product manufacturing process: PTFE membrane lamination has three lamination methods:
Hot-press lamination: Utilizing the low-melting-point fibers of the base fabric, the PTFE membrane is thermally bonded to the base fabric under specific temperature and pressure.
Adhesive lamination: Using special chemical-resistant adhesives for lamination, mostly used for industrial coarse filtration with slightly lower purity.
Ultrasonic lamination: Utilizing high-frequency ultrasonic vibration to generate heat for localized thermal fusion.
Applications of Liquid filtration membrane-coated nonwoven fabric: MBR membrane bioreactor filtration components, filter cloths for chamber or belt filter presses, pharmaceutical and food and beverage industries (high-purity filtration)
