Embodiment Construction

[0013] Specific implementation plan

[0014] The present invention will be described in detail below through specific examples.

[0015] A cordierite composite ceramic filter element prepared from the following parts by weight (kg) of raw materials: cordierite 13, mullite 9, coarse-pored silica gel 6, montmorillonite 4, activated alumina 8, calcium sulfate 3, two Methyl silicone oil 2, sodium alginate 3, palm fiber 3, urea 2, modified coconut shell activated carbon 5, appropriate amount of water;

[0016] The modified coconut shell activated carbon is made of the following parts by weight (kg) of raw materials: crushed coconut shell 20, zirconia 5, and finely powdered silica gel 3. The preparation method is to wash the crushed coconut shell with hot water, and then use 50 parts at room temperature. Soak -60% phosphoric acid solution for 1-2 hours; filter, take the filter residue and carbonize it in a carbonization furnace at 550-600℃ for 1.5-2 hours, take it out; when the temperatur...

Abstract

The invention discloses a cordierite compound ceramic filter element. The cordierite compound ceramic filter element is characterized by being prepared from the following raw materials in parts by weight: 13-15 parts of cordierite, 9-11 parts of mullite, 6-8 parts of silochrom, 4-7 parts of smectite, 8-10 parts of activated alumina, 3-5 parts of calcium sulfate, 2-3 parts of dimethyl silicon oil, 3-4 parts of sodium alginate, 3-5 parts of palm fibers, 2-3 parts of urea, 5-7 parts of modifying coconut active charcoal, and the defined amount of water. The cordierite compound ceramic filter element provided by the invention has the advantages that the silochrom is added, so that the adsorptive property and heat stability are good, the chemical property is stable, and the mechanical strength is high; the palm fibers are added, so that the tenacity of the filter element is added, meanwhile, the cordierite compound ceramic filter element has a porous property, and the filtering adsorptive property is improved; the modifying coconut active charcoal is added, so that the gap structure is developed, the adsorptive property is good, the intensity is high, the regeneration is easy, and the cordierite compound ceramic filter element is economical and durable, is long in service life, is corrosion-proof and 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 cordierite composite ceramic filter element and a preparation method thereof. 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, the environmental pollution is very serious. The haze weather brings great harm to people. Air adsorption filter materials can adsorb 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...
