Embodiment Construction

[0012] A carbon crystal composite microporous ceramic filter element, made of the following parts by weight (kg) of raw materials:

[0013] Light calcium carbonate 12, kaolin 12, diatomaceous earth 9, bamboo charcoal powder 10, charcoal powder 6, straw ash 2, celestite powder 12, talc powder 8, mica powder 5, chlorinated paraffin 10, ethanol 14, modified bentonite 35. Appropriate amount of water.

[0014] The modified bentonite is prepared by the following method:

[0015] Put the bentonite into 490-520℃ for calcination for 3-4 hours, take it out, cool it, soak it in a 10-12% hydrochloric acid solution for 3-4 hours, take it out, wash it with pure water, dry and grind it into powder; then add the equivalent In the bentonite weight 40% aluminum nitride, 3% alum powder, 3% zeolite powder, 18% Tianji yellow powder, mix and stir for 30-40 minutes, and then spray the equivalent of 5% of the bentonite weight Triethoxysilane is stirred at 12000-15000 rpm for 60-80 minutes to...

Abstract

The invention provides a carbon crystal composite microporous ceramic filter core and a preparation method thereof. The invention is characterized in that the ceramic filter core is prepared from the following raw materials by weight: 12 to 14 parts of light calcium carbonate, 9 to 12 parts of kaolin, 7 to 9 parts of diatomite, 10 to 12 parts of bamboo charcoal powder, 4 to 6 parts of charcoal dust, 1 to 2 parts of straw ash, 12 to 14 parts of celestine powder, 6 to 8 parts of talcum powder, 3 to 5 parts of mica powder, 10 to 12 parts of chlorinated paraffin, 12 to 14 parts of ethanol, 25 to 35 parts of modified bentonite and a proper amount of water. The ceramic filter core provided by the invention has a plurality of functions like filtration, adsorption and suppression of bacterial reproduction and has the protruding advantages of high purification efficiency, high temperature resistance, small pressure loss, corrosion resistance, a long service life, removal of dust in air, etc.

Description

Technical field [0001] The invention belongs to the technical field of filter materials, in particular to a carbon crystal composite microporous ceramic filter element and a preparation method thereof. Background technique [0002] Filter materials have a wide range of uses, widely used in chemical, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries; the most common are automobile air filters, which are used to filter the air entering the engine and remove particles and particles in the air. Mechanical impurity components are blocked to prevent these components from entering gasoline, diesel or engine oil to ensure the normal operation of the engine. There are also a large number of filter materials used in the air conditioning system. At present, the environmental air pollution is very serious, which greatly harms human health. Air filter materials can absorb all kinds of harmful particles in the air to prevent entering people's livi...
