High-filterability composite cordierite ceramic filter element

Abstract

The invention discloses a high-filterability composite cordierite ceramic filter element. The high-filterability composite cordierite ceramic filter element is characterized by comprising, by weight, 25-40 parts of cordierite, 20-40 parts of normal hexane, 35-70 parts of granite pegmatite, 10-40 parts of quartz sand, 5-17 parts of white cement, 35-47 parts of ordinary Portland cement, 20-50 parts of pyrophyllite, 11-38 parts of fiber brucite, 1-9 parts of silica, 11-35 parts of methylcellulose, 10-17 parts of pitch, 4-9 parts of zirconium oxide, 1.5-3.6 parts of boron nitride, 12.5-37.9 parts of bud naw powder and 15-60 parts of zirconium oxide. The high-filterability composite cordierite ceramic filter element is high in adsorptive property, high in thermostability, stable in chemical property and high in mechanical strength; furthermore, the filter element is good in toughness and has porous performance, and therefore filtration and adsorption performance is improved; the filter element is porous, high in adsorptive property and strength, easy to regenerate, economical and durable; besides, the filter element is long in service life and resistant to corrosion and can be used for air adsorption filtration.

Description

technical field

[0001] The invention relates to a cordierite composite ceramic filter element with high filterability. Background technique

[0002] Filter materials are widely used, 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 material is used in the air conditioning system. Now the air pollution in the environment is very serious, and the smog weather has brought great harm to people. The air adsorption filter material can absorb various harmful particles in the air, such as PM2.5 , prevent entering 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. The existing filter materials mainly include honeycomb ceramics, fi...
