Problems solved by technology

Activated carbon is used in the industrial field for decolorization, refining, and purification of liquid phase adsorption. In terms of gas phase adsorption, powdered and granular activated carbon cannot be in close contact with toxic and harmful substances in the air, thus greatly reducing the adsorption effect.
[0004] On the other hand, the current activated carbon application technology lacks the ability to ensure that activated carbon has a good function of absorbing dirt and has a good killing effect on microorganisms that make people sick, especially the lack of activated carbon used in hospitals and other environments.

Embodiment 1

[0026] Embodiment 1: The weight ratio of the raw materials used is: 35 parts of chemical activated carbon, 27 parts of coal-based granular activated carbon, 40 parts of coconut shell activated carbon; three kinds of activated carbons with different proportions are put into a ball mill for ball milling, and ground into The mesh number is 500 mesh activated carbon powder. Get 102 parts of activated carbon powders that are ground into, 5 parts of nano-silver with a purity of 99%, 1.5 parts of methyl cellulose, and 1.5 parts of talcum powder. Add the above-mentioned raw materials into the mixer in turn, stir and mix evenly to make a mixture. Then put the mixture in a kneader (or mixer), add moderate distilled water, knead for 30 minutes, and knead it into a mud paste in the kneader. Then the mud paste is placed in a vacuum mud mill, and mud is honed into a uniform plasticized mud paste in the vacuum mud mill. Then put the plasticized mud paste in the extrusion molding, and extru...

Embodiment 2

[0028] Embodiment 2: The weight ratio of the raw materials used is: 32 parts of chemical activated carbon, 30 parts of coal-based granular activated carbon, 38 parts of coconut shell activated carbon, three kinds of activated carbons with different proportions are put into the ball mill for ball milling, and ground into The mesh number is 500 mesh activated carbon powder. Then get the activated carbon powder that is ground into, 6 parts of nano-silver with a purity of 99%, 2 parts of methylcellulose, and 2 parts of talcum powder. The above-mentioned raw materials are sequentially added to stirring and mixing, stirring evenly to make a mixture. The rest of the steps are the same as in Example 1, wherein the profile with a moisture content of less than 10% is placed in a furnace for sintering at a sintering temperature of 900° C. for 5 hours.

Abstract

The invention relates to nano-silver honeycomb-type purification activated carbon and a preparation method thereof. The nano-silver honeycomb-type purification activated carbon uses the following raw materials in part by weight: 32 to 38 parts of chemical activated carbon, 25 to 30 parts of granular activated carbon from coal, 35 to 42 parts of cocoanut active charcoal, 4 to 6 parts of nano-silver with purity of 99 percent, 1 to 2 parts of methylcellulose and 1 to 2 parts of talcum powder. The method comprises the following steps: carrying out ball milling, mixing the raw materials with uniformly stirring to obtain a product material; carrying out vacuum pugging, extrusion forming, air-drying and sintering to obtain the nano-silver honeycomb-type purification activated carbon. According to the invention, the activated carbon can be guaranteed to have an excellent dirt adsorption function, also can have an excellent effect of killing and inhibiting microorganisms which are pathogenic for people, is suitable for the environment such as a hospital and the like, and also has the advantages of firmness for sizing, durability, simple and practicable method, low pollution control cost, low carbon, energy saving and good treatment effect.
