Problems solved by technology

Filter elements are the core components of water purification equipment. Porous ceramics have become ideal materials for water purifier filter elements due to their high separation efficiency, energy saving, stable structure, and easy regeneration. Better, but with the increase of filtration time, the sterilization effect will gradually become worse, the service life will be short, and even secondary pollution will occur during the sterilization process

Abstract

The invention provides a high-performance ceramic filtering core. The filtering core is prepared from the following ingredients in parts by mass: 25-35 parts of alpha-alumina powder, 25-35 parts of 0.7-micron alpha-alumina powder, 15-25 parts of kaolin, 10-25 parts of magnesian clay, 3-7 parts of dolomite dust, 3-7 parts of talcum powder, and 5-15 parts of a rare earth activated complex antimicrobial agent, wherein the 0.7-micron alpha-alumina powder has grain fineness reaching 0.75 micron. The ceramic filtering core has high filtering precision and long-acting bactericidal property without causing secondary pollution.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a high-performance ceramic filter element. Background technique [0002] With the continuous improvement of people's living standards, people pay more and more attention to health preservation and health, especially the water for daily drinking. Filter elements are the core components of water purification equipment. Porous ceramics have become ideal materials for water purifier filter elements due to their high separation efficiency, energy saving, stable structure, and easy regeneration. Better, but with the increase of filtration time, the sterilization effect will gradually become worse, the service life will be short, and even secondary pollution will be generated during the sterilization process. Contents of the invention [0003] In view of the existing deficiencies, the purpose of the present invention is to provide a high-performance ceramic filter element...
