Characteristic analysis of filter element with different material

In our lives there are a variety of filter elements, according to the material can be divided into: paper, chemical fiber, PP filter elements, wire gap, metal mesh, metal powder sintering, activated carbon, etc. . Because of its unique nature of stainless steel filter, metal stainless steel filter mostly to stainless steel-based. To stainless steel 304,316L two kinds of high-quality stainless steel material, production of excellent performance and quality of all kinds of stainless steel filter. Stainless steel filter core with corrosion resistance, high strength, high temperature resistance, high filtering accuracy, easy regeneration and other excellent performance, it has excellent mechanical properties, cutting, welding and other machining, high compressive strength, the internal pressure failure strength is more than 2 mpa, the service temperature in the air can reach -50 ~ 900 ° C, it is suitable for filtration of all kinds of corrosive media, examples are hydrochloric acid, sulfuric acid, hydroxide acid, seawater, aqua regia and chloride solutions such as iron, copper and sodium. The filter core is formed by powder and sintered at high temperature, the shape is stable, so the surface particles are not easy to fall off, the structure of the filter core is not easy to change, and it is resistant to impact and alternating load, and its filtering accuracy is easy to guarantee, even in high temperature and high pressure, the aperture will not be deformed. Its air permeability, separation effect is stable, porosity can reach 10 ~ 45% , pore size distribution is uniform, pollution capacity is large, and the regeneration method is simple.

The material and characteristics of various kinds of filter elements can be used repeatedly after regeneration and the effect of PP melt-blown filter elements, material: take food grade polypropylene as raw material, adopt the international general gradual diameter process production, after heating melting, the fiber formed three-dimensional micro-pore structure in the process of thermal bonding. The micro-pore diameter was gradient distribution from inside to outside, and it integrated surface and deep coarse-fine filtration. Features: thick fiber outer layer, thin fiber inner layer, outer layer loose, inner layer tight gradient tight structure. The unique gradient deep layer filtration forms the three-dimensional filter residue effect, has the high porosity, the high rejection rate, the large sewage capacity, the large flow rate, the low pressure drop characteristic. PP melt-blown filter element has high self-cleanliness and no pollution to water quality. Acid, alkali and other chemical reagents and organic solvents corrosion. PP melt-blown filter core strength, when the filter inlet and outlet pressure difference is 0.4 mpa, filter core deformation. Function: filter precision is divided into 1 micron and 5 micron. Initial filtration of raw water to remove suspended matter, sediment, rust, colloid and other substances, the formation of RO membrane water requirements. Winding filter core, material: its yarn material has polypropylene fiber, acrylic fiber, degreased cotton fiber, etc. . Features: by a good filter performance of textile fiber yarn precision winding in the porous skeleton refined from the. Filter cores with different precision can be made by controlling the winding tightness and density of the yarn. Function: it can remove suspended matter and particle impurities in water. Folding filter element, material: the use of polypropylene hot-jet fiber membrane, nylon, polytetrafluoroethylene microporous filter membrane for the filter media made of precision filter devices. Features: filter cover seal and the whole structure of the connection are using hot-melt bonding, with small size, large filter area, high accuracy and so on. Function: filter precision from 0.1 micron to 60 micron. Can remove the visible particles in the water, suspended matter, etc. .

Stainless steel wire mesh filter core, material: stainless steel features: high strength, good rigidity, uniform precision, can be used repeatedly. Function: filter precision from 30 to 80 microns, can remove the visible particles in the water, suspended solids and so on. Granular activated carbon filter core (UDF) material: non-toxic, tasteless and efficient coconut shell activated carbon and coal-based activated carbon as the main body, supplemented by food-grade material binder, by a special process molding. Features: food grade ABS plastic for shell, bonded with Ultrasonic welding technology. Function: adsorption of organic matter in water, chemical pesticides, residual chlorine, off-color odor and so on. Compressed activated carbon filter core, material: the use of iodine 900 above coal-based carbon as a filter material. Features: after three times of desulphurization iron processing, or with high-quality plant carbon, with food-grade adhesive sintered compression molding. Both inside and outside the compressed activated carbon are wrapped in a layer of non-woven fabric with filtering function to ensure that the carbon core itself does not drop carbon powder, and both ends of the carbon core are equipped with a soft NBR rubber seal, the carbon core can be loaded into the filter barrel with good sealing performance. Function: remove the residual chlorine, chemical pesticides, color, smell, and filter the fine impurities. After the active carbon filter core, material: the use of high-quality coconut shell activated carbon filter material. Features: some of the high-quality activated carbon filter media containing silver treatment, the use of silver atoms of the sterilization principle of pure water pipeline water purifier bacteriostasis, to ensure safe and sanitary water. Function: adsorb impurities and peculiar smell in water, improve the taste of water, eliminate peculiar smell. Ceramic filter core, material: usually made of natural diatomite fired. Features: it can be cleaned repeatedly or sanded with sandpaper. It has high precision and long life.
