Abstract

The invention discloses a silochrom added ceramic filter element with good stability. The silochrom added ceramic filter element is characterized by being prepared from the following raw materials in parts by weight: 10-12 parts of activated carbon fiber, 12-13 parts of kaolin, 8-10 parts of mullite, 9-11 parts of zeolite powder, 6-8 parts of powdered aluminum, 4-7 parts of silochrom, 1-2 parts of polyvinyl alcohol, 3-5 parts of wheat flour, 3-5 parts of smashed Badam shell, 3-5 parts of smashed cotton hull, 1-2 parts of epoxidized soybean oil, 5-7 parts of modified cocoanut active charcoal and a proper amount of water. Due to the addition of the silochrom, the ceramic filter element is high in adsorptive property, good in thermal stability, stable in chemical property and high in mechanical strength; due to the addition of the Badam shell and cotton hull, the tenacity of the filter element is increased, and the filtering adsorptive property is improved because of porous performance; due to the addition of the modified cocoanut active charcoal, the ceramic filter element is large in gaps, good in adsorptive property, high in strength, easy to regenerate, economical and durable; the filter element can be used for air adsorption filtration.

Description

technical field [0001] The invention relates to a filter material and a preparation method thereof, in particular to a ceramic filter element with good stability added with coarse-pore silica gel and a preparation method thereof. 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 materials are used in air conditioning systems. Now the environmental air pollution is very serious, and the 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 entering people's living or working environment, reduce the inhalation of harmful substances such as particulate matter in human lungs, improve people's quality of life, and redu...
