Commonly used PP cotton filter, wire wound filter, folding filter are applicable to what scenarios are used
Melt-blown filter element
PP cotton melt-blown filter core is a filter material, the application of polypropylene as a raw material, after heating and melting after gushing, traction belt, accept forming and made. The filter element has the advantages of uniform diameter and deep filtration structure with thin outside and dense inside, and has high filtration rate and corrosion resistance. It can effectively remove suspended solids, particles and rust in the liquid.
Melt-blown filter element is a tubular filter element made by melting non-toxic and odorless PP particles by heating, and by spinning, lashen and forming. If the raw material is usually polypropylene, it can be called PP melt-blown filter element.
It is not only widely used in the water treatment industry, but also can be adapted to chemicals, suitable for strong alkali, strong acid and organic solutions. It has excellent pollution absorption capacity and long service life, and the cost is relatively low.

Wire wound filter element
Wire-wound filter element is a deep filtration device for high viscosity and low residue filtration. The filter element is made of textile fiber wire (such as polypropylene wire wiring, fat removing cotton rope, etc.) wrapped on polypropylene or stainless steel porous structure skeleton according to special processing technology. The honeycomb structure of the filter element has loose surface and internal structure density, which can effectively remove suspended matter, particles, rust and other impurities in the liquid, and has excellent filtration accuracy.
When winding the wire filter device, the relative density of the filter element should be adjusted according to the size of the wire or the support force of the wire, and the standard of slow compaction from outside to inside should be achieved. Only the winding filter element with internal structural density and loose external structure can obtain the actual effect of deep filtration, thereby increasing the filtration rate and blocking more residual particles. The filtration efficiency of the coil filter element depends on the size of the wire and the relative density of the coil. The thinner the lines, the more closely stacked together, the lower the porosity, the greater the filtration efficiency; The denser the line structure, the higher the filtration efficiency will be. However, in the filtration process, the filter element must be able to maintain its special structure and diameter size to provide stable and uniform filtration quality.
