Regarding
PVDF Products, the advantages and disadvantages of ultrafiltration water purifiers?
Good answer 1:
Advantages of pvdf ultrafiltration membrane:
1. Has good hydrophilicity
The pvdf ultrafiltration membrane is specially treated during production, so that the membrane filaments of the pvdf ultrafiltration membrane have good hydrophilicity for a long time, and can have a high water production under a low operating pressure during use. At the same time, the anti-pollution ability of the membrane filament is also very good.
2. Filtration accuracy is very high
Pvdf ultrafiltration membrane can also be called hollow fiber ultrafiltration membrane. The membrane pores of pvdf ultrafiltration membrane are very small, generally less than 0.1 micron, which can well remove microorganisms, colloids, diatoms and other small impurities in water.
3. Good physical properties
The physical properties of the PVDF ultrafiltration membrane are very good, mainly manifested in the high mechanical strength and the ability of the membrane to resist broken filaments, because if the ultrafiltration membrane is broken, it is a very serious matter, and a large number of broken filaments can only be replaced. Ultrafiltration membrane, and the ability to resist broken wires is also an important indicator to measure the quality of an ultrafiltration membrane.
4. Long service life, strong surface pollution ability
The ultrafiltration membrane made of pvdf has good chemical corrosion resistance, oxidation resistance and light aging resistance. Therefore, if this ultrafiltration membrane is polluted during use, it can be removed by various cleaning methods. pollutants, allowing them to restore flux.
5. High filtration stability
Start with the supply of raw materials, preparation process and product testing. Guarantee the stable quality of raw materials, consistent precise control during the preparation process and 100% product testing to ensure the stable performance of the product.
6. Service life: The service life is not less than 5 years, and the ordinary film can only be used for 2~3 years
Disadvantages of pvdf ultrafiltration membrane:
1. The production process of pvdf ultrafiltration membrane is more complicated than that of other materials, because the membrane pores of pvdf ultrafiltration membrane are small, so it is easy to
Block and it is troublesome to clean.
2. The process of pvdf ultrafiltration membrane is relatively complicated. The small pores of this ultrafiltration membrane can be said to be an advantage, and it can also be said to be a disadvantage. The advantage is that the water quality after filtration is more pure, and the disadvantage is that it will be easily blocked if it is not cleaned in time. , and the membrane is too small to clean, so be sure to pay attention to the pressure when cleaning, not high-pressure cleaning, to avoid damaging the ultrafiltration membrane
3.Pvdf ultrafiltration membranes are more expensive than ordinary ultrafiltration membranes, so the cost of using pvdf ultrafiltration membranes is relatively high.
Good answer 2:
The advantage of the pvdf ultrafiltration water purifier is that it can completely filter impurities in the water and make the tap water meet the standard of direct drinking. Its disadvantage is that if the filter element and filter are not replaced in time, it will cause water pollution. The growth of bacteria.
