A kind of ceramic filter purification material and preparation method thereof

Abstract

The invention discloses a ceramic filter purifying material which comprises main materials and auxiliary materials. The main materials are kaolin, the mixing amount of the kaolin is 20%-80% in weight percentage, the auxiliary materials comprise tourmaline, radium stones, rare earth, crystal quartz, clay, powdered borax, foaming agents, catalysts, cocoanut active charcoal, titanium oxide and zirconium oxide, and total mixing amount of the auxiliary materials is 20%-80% in weight percentage, filtering holes with irregular hole diameters are uniformly formed in the inside and the outer surface of the ceramic filter purifying material, the diameter of each filtering hole ranges from 0.01 micrometer (10 nanometers) to 500 micrometers (0.5 millimeter), the volume of each filtering hole is 0.02-1.5cm<3>/g, surface scratch hardness reaches grade 6, compression-resistant hardness is 100-170kg/cm<2>, the weight is 0.09-0.21g/cm<3>, the hole diameter of one side is large, and the hole diameter of the opposite side is small, so that a conical structure is formed. The preparation method of the materials includes the steps: grinding the main materials and the auxiliary materials, screening the grinded mixture by the aid of a 100-150-mesh sieve, and grinding parts of materials to form particles with the diameter ranging from 1 to 3 micrometers; firing and simultaneously mixing the mixture at the temperature ranging from 60 DEG C to 80 DEG C; performing pressing formation; firing clay at the temperature ranging from 800 DEG C to 1300 DEG C to form ceramic products. The ceramic filter purifying material is high in hardness, environmentally friendly, healthy and reusable.

Description

technical field [0001] The invention relates to a ceramic material capable of filtering air and water and a preparation method thereof, especially a ceramic material capable of adsorbing harmful substances such as benzene and formaldehyde in the air, which has high purification efficiency, high hardness, multiple functions, light weight, shapeability, A ceramic material capable of being compounded, attached (repeatedly used), recyclable, non-contaminating, energy-saving and environmentally friendly, and improving the quality of filtered water, and a preparation method thereof. Background technique [0002] At present, the high-efficiency air filter on the market is called (HEPA), most of which use fine glass fiber, paper, etc. as the filter medium, or use PP spray material or paper spray material to achieve the filtration of fine particles in the air ( Up to 0.3 microns), at the same time, by adding activated carbon powder layer to filter harmful gases, adding sponge layer f...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a ceramic filter material and its preparation method. The ceramic material can be washed with water, blown by wind, ultrasonically cleaned, baked at high temperature or returned to the furnace to burn the particles after the ceramic material is saturated to a certain extent. It can be reused after desorption from harmful substances, which can effectively save costs. Compared with PP and other materials, the ceramic air and water filter element has a higher hardness and a smaller drag coefficient at the same pore size. Compared with traditional materials with the same volume More pores, so the dust holding capacity is higher; it can purify, eliminate bacteria, deodorize, release negative ions and sub-oxygen, and small molecule water clusters. The filter pore size of this product can reach 6 nanometers, which can effectively filter E. coli, formaldehyde, Benzene, ammonia and other harmful substances function (coconut shell carbon fiber, catalyst and micropores can effectively block and remove formaldehyde, benzene and other harmful substances and odors, and block smaller harmful bacteria such as 0.5-1 micron Escherichia coli), while releasing negative ions and oxygen , Hydrogen ions (flowing water molecules in the air and water will produce natural electrolysis when flowing through magnesium-rich tourmaline spar, instantly electrolyze water molecule H2O, and generate H+/OH-/H3O2/4H+/O2); The air is cleaner and the nutrients are higher; 6-nanometer water molecules can be electrolyzed to achieve smaller nano-molecular cluster water, which can make the water safer and cleaner, with better taste, more minerals, higher absorption efficiency of the human body, and more efficacy Performance; and has high hardness of silicon crystal, extremely convenient transportati
