Description
本発明は、活性炭素繊維焼結フィルターエレメントに関し、浄水分野に属する。 The present invention relates to an activated carbon fiber sintered filter element and belongs to the water purification field.
人々は、飲用水の安全を重視すると共に、市場では様々な飲用水処理用のフィルターエレメントが出現し、顧客に認可されたフィルターエレメントは、主に、押出し活性炭素粉末フィルターエレメントと焼結活性炭素粉末フィルターエレメントである。押出し活性炭素粉末フィルターエレメントは、活性炭素粉末に接着剤を添加して加温して押出し機で押出してなり、大部分の活性炭素粉末の顆粒とお互いの間の微小孔は、接着剤で覆われて目詰まり、それにより、製品の吸着効果を悪くする。活性炭素粉末焼結フィルターエレメントは、超高分子量ポリエチレンと活性炭素粉末とが混合した後に、プレスし、半溶融で焼結し、成型するフィルターエレメントであり、押出し活性炭素フィルターエレメントに比べて、超高分子量ポリエチレンが焼結成型時に表面が溶融する半溶融状態であり、多くの活性炭素粉末の微小孔に目詰まることがしなく、活性炭素粉末の間隙率が倍に増加し、それにより、製品は、比較的良い吸着効果を有するが、強度が低く、粉末を落とし、流れが小さく、吸着効果が不良である問題が存在する。 People place importance on the safety of drinking water, and various filter elements for the treatment of drinking water have emerged in the market. Filter elements approved by customers are mainly extruded activated carbon powder filter elements and sintered activated carbon. It is a powder filter element.

Clogging, thereby deteriorating the adsorption effect of the product. The activated carbon powder sintered filter element is a filter element that is mixed with ultra high molecular weight polyethylene and activated carbon powder, then pressed, sintered in a semi-molten state, and molded. Compared with an extruded activated carbon filter element, High-molecular-weight polyethylene is in a semi-molten state where the surface melts during sintering molding, and it does not clog the pores of many activated carbon powders, and the porosity of activated carbon powders doubles, thereby Has a relatively good adsorption effect, but there is a problem that the strength is low, the powder is dropped, the flow is small, and the adsorption effect is poor.
