Purpose of winding filter element:
1、 Electronics and power industry: pure water, gas, electric crossover fluid, printing line plate.
2、 Chemical and petrochemical industry: solvent, coating, magnetic slurry, detergent, liquid wax.
3、 Pharmaceutical industry: hospital water, pharmaceutical injections, Chinese medicine.
4、 Food industry: food, beverage, drinking water and alcohol.
Wound filter element is a kind of deep filter element, which is used for filtration with low viscosity and low impurity quality. It is made of textile fiber thread (polypropylene fiber thread, degreasing cotton thread, etc.) accurately wound on the porous skeleton (polypropylene or stainless steel) according to a specific process. It has a honeycomb structure with sparse outside and dense inside, can effectively remove suspended solids, particles, rust and other impurities in the fluid, and has excellent filtration performance.
The ideal condition is that the filter material becomes more and more dense from outside to inside. Therefore, when winding, the density of filter material must be controlled by the thickness of steel wire or different winding tension. The wound filter element with internal dense and external sparse structure can produce depth effect on deep filter material, effectively improve filtration efficiency and intercept more dirty particles.
The filtering accuracy of wound filter material is determined by the thickness of conductor and winding density. The finer the wire, the closer it can be connected, the smaller the pore, and the higher the precision; Similarly, the denser the wire structure, the higher the filtration accuracy. However, in the filtration process, the filter material must be able to maintain its specific structure and pore size.
