Abstract

The invention discloses a ceramic filter element added with silver iodide and provided with antibacterial effect, the ceramic filter element is characterized by comprising the following raw materials in part by weight: 13-15 parts of active carbon, 10-12 parts of bentonite, 9-11 parts of zeolite powder, 3-4 parts of zinc oxide, 8-10 parts of phenolic resin, 2-3 parts of urea, 3-5 parts of ammonium chloride, 5-8 parts of light calcium carbonate, 5-7 parts of bauxite, 1-2 parts of silver iodide, 5-8 parts of silicon nitride, 3-5 parts of palm fiber, 5-7 parts of modified cocoanut active charcoal and appropriate water. The silver iodide is added in the filter element to provide the antibacterial effect, the palm fiber is added to increase the toughness of the filter element, and the porous performance is provided, and the filtering adsorption performance is improved; the modified coconut active charcoal is added, the filter element is developed in gap, good in adsorption performance, high in strength, easy to regenerate, economic and durable; the raw material is simple and easy to obtain, the cost is low, the purifying efficnecy is high, the filter element is corrosion resistant, and can be used for air adsorption filtering and sewage treatment.

Description

technical field [0001] The invention relates to a filter material and a preparation method thereof, in particular to a ceramic filter element with antibacterial effect added with silver iodide 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,...
