The principle of the oil and water repellent filter bag

The principle of the oil and water repellent filter bag:

The reactive working fluid is used to prepare the filter media impregnated with the fluorine reactive agent so that the working fluid reacts with certain groups in the macromolecular structure of the filter fiber to form a macromolecular chain, which changes the affinity between the fiber and water and oil, So the surface tension of the filter material is reduced unless the surface tension of water and oil to achieve the purpose of water repellent and oil repellent.

Production process:

Opening of fiber — carded — stacking network — to acupuncture — main acupuncture — calendering — impregnation of water and oil proof working fluid — baking — heat adjustment — the finished product.
