PVDF folding filter, also known as polyvinylidene fluoride folding filter, is a widely used filter product in water treatment and other industrial fields. Its characteristics are mainly reflected in the following aspects:


1、 Material characteristics


Chemical resistance: PVDF material has excellent chemical resistance and can resist the erosion of various organic and inorganic solvents, including strong acids, aliphatic, aromatic, ketone, ether and other solvents. This enables the PVDF folding filter to operate stably in complex water quality environments and is not easily damaged by chemical substances.


High temperature resistance: PVDF material has good high temperature resistance and can withstand high-pressure steam disinfection below 138 ℃, making it suitable for filtration operations in high-temperature environments.


2、 Structural Design


Folding design: The PVDF folding filter adopts a folding design, which significantly increases the usage area of the filter material by folding it along a certain length to form a longitudinal texture. This design not only improves filtration efficiency, but also more effectively captures and removes impurities such as suspended solids, particulate matter, organic matter, and microorganisms in water.


Multi layer gradient pore size filtration structure: PVDF folding filter element adopts deep fine membrane material, scientifically designed multi-layer gradient pore size filtration structure, making the filter element have the characteristic of high pollutant holding capacity. This structure can extend the service life of the filter element, reduce the frequency of replacement, and thus save user costs.


3、 Filtering performance


Efficient filtration: PVDF folding filter cartridge has efficient filtration effect, which can effectively remove impurities and microorganisms in water and improve water quality. Its unique structure and material properties ensure the filtration accuracy and efficiency of the filter element.


Uniform pore size distribution: The pore size distribution of PVDF folding filter cartridge is uniform, with a porosity of up to 80-95%, which greatly improves the filtration speed and enables the filter cartridge to maintain efficient filtration performance even when dealing with large amounts of water.


4、 Service life and maintenance


Long lifespan: Due to the chemical and high temperature resistance of PVDF material, as well as the folding design and multi-layer gradient pore size filtration structure of the filter cartridge, the service life of PVDF folding filter cartridge is relatively long.


Convenient replacement and cleaning: The folding structure of PVDF folding filter element makes the filter element more compact, easy to store and replace. Meanwhile, PVDF material itself is easy to clean, and impurities attached to the filter layer can be removed through backwashing or chemical cleaning, extending the service life of the filter element.


5、 Application Fields


PVDF folding filter cartridges are widely used in household water purifiers, industrial wastewater treatment, pharmaceutical manufacturing, food processing, biological products, fruit juice beverages, petrochemical industry, and high-purity water preparation. Its excellent filtering performance and material properties make it an indispensable filtering element in these fields.


Above all, PVDF folding filter cartridges play an important role in water treatment and other industrial fields due to their chemical resistance, high temperature resistance, efficient filtration performance, long lifespan, and convenient replacement and cleaning.
