Description

Technical field [0001] The invention relates to a high-performance cordierite composite ceramic filter element. Background technique [0002] Filter materials are extremely versatile, mainly used in coatings, inks, dyes, plastics, pharmaceuticals, electroplating, beverages, cosmetics, rubber, printing, electronic tube production, circuit board production, waste incineration, chemical production and other fields. The most common filter materials are used in air conditioning systems. At present, environmental pollution is very serious, and haze weather has brought great harm to people. Air adsorption filter materials can absorb various harmful particles in the air, such as PM2.5. , Prevent entry into people's living or working environment, reduce the inhalation of harmful substances such as particulate matter in the human lungs, improve people's quality of life, and reduce the occurrence of diseases. Existing filter materials mainly include honeycomb ceramics, filter paper, activa...
