1. PVDF ultrafiltration membrane has good hydrophilicity
After special hydrophilic treatment, the ultrafiltration membrane had long-term hydrophilic property, and the hydrolyzed antenna decreased from 79-90 degrees before modification to 30-35 degrees. It can obtain high water flux at low transmembrane pressure and improve the pollution resistance of membrane filament.

2. High filtration accuracy of PVDF ultrafiltration membrane
With uniform micropores less than 0.1 micron, it can remove microorganisms, colloids, diatoms and other substances that cause turbidity.
3. PVDF ultrafiltration membrane has good mechanical strength
The mechanical strength of the ultrafiltration membrane reflects the resistance of the membrane to wire breakage, which makes the membrane lose its separation performance and is an important index to evaluate the performance of the ultrafiltration membrane.
4. PVDF ultrafiltration membrane has a long life and strong anti-fouling ability
It has good resistance to chemical corrosion, oxidation and light aging. A variety of methods can therefore be used for repeated cleaning to remove contaminants and restore flux.
5. Stable product performance
From the raw material supply, preparation process and product testing. Ensure the stable quality of raw materials, consistent and accurate control during the preparation process and 100% product testing to ensure the stability of the product.
