Abstract

The invention discloses a composite medical stone ceramic filter element rich in trace elements, which is prepared from the following raw materials in parts by weight: 13-15 parts of medical stone, 9-11 parts of diatomite, 10-13 parts of nut shell activated carbon, 8-10 parts of activated aluminum oxide, 1-2 parts of chitosan, 7-9 parts of light calcium carbonate, 3-4 parts of zinc oxide, 7-9 parts of montmorillonite, 2-3 parts of ammonium bromide, 4-6 parts of polyvinylpyrrolidone, 5-7 parts of anthracite filter material, 3-5 parts of palm fiber, 5-7 parts of modified cocoanut shell activated carbon and a proper amount of water. As the palm fibers are added, the toughness of the filter element is improved; meanwhile the palm fibers have multi-porous performance, the filtration and adsorption performances are enhanced; as the modified cocoanut shell activated carbon is added, the filter element is sufficient in gaps, good in adsorption performance, high in strength, easy to regenerate and economical and durable; as the added medical stones serving as the raw material contain a lot of trace elements, the trace elements are separated while adsorbing, and the filter element is environmentally friendly. The filter element disclosed by the invention can be used for air adsorption and filtration.

Description

technical field [0001] The invention relates to a filter material and a preparation method thereof, in particular to a medical stone composite ceramic filter element rich in trace elements 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 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...
