More Information
Summary:The invention discloses a preparation method of a filter element, which is characterized by comprising the following preparation steps: 1) preparation of mineralized particles: mixing a polymer and a mineralized filler according to a mass ratio of (50-500): 1, and extruding and granulating by adopting a melt blending method; (2) preparing a polymer mixture, namely mixing a polymer and a modifier, wherein the mass percent of the modifier is 5-30%, and the balance is the polymer; and 3) preparing the melt-blown filter element. The double-layer filter element with the mineralization layer located on the outer layer and the polymer layer located on the inner layer is prepared through the layered melt-blowing technology, water to be treated flows into the inner layer from the outer layer of the melt-blowing filter element, and when the water flows through the outer layer, mineralization filler in the mineralization layer mineralizes the water, so that the content of mineral substances in the water is increased; wh
