Problems solved by technology

However, the adsorption of activated carbon on substances is selective, non-polar substances are easier to adsorb than polar substances, so the absorption of polar substances is limited; in addition, the adsorption of homologues generally increases with the increase of boiling point , so the absorption of lower boiling homologues is also limited

Embodiment Construction

[0017] figure 1 It is a process flow chart of the present invention, and the specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] The nano-silver filter carbon core is composed of activated carbon and nano-silver, and the specific molding process is as follows:

[0019] 1. Material selection:

[0020] The particle size of activated carbon: 50 mesh;

[0021] Nano silver particle size: 20nm;

[0022] 2. The ratio of nano-silver to activated carbon: 4g pure nano-silver / kg of activated carbon.

[0023] 3. Mix the nano-silver with tap water or deionized water first and stir evenly, then pour the activated carbon into the vacuum container, then pour the nano-silver aqueous solution into the vacuum container for vacuum impregnation, pour in the nano-silver aqueous solution to submerge the activated carbon The immersion time shall be based on the fact that there are no bubbles overflowing in the wate...

Abstract

The present invention relates to a filtered activated carbon core, in particular to a nanometer silver filtered activated carbon core and a manufacturing method thereof. The nanometer silver filtered activated carbon core consists of activated carbon and nanometer silver. A concrete molding technology is as follows: material selection; the proportion of the nanometer silver and the activated carbon is 0.5-8g of pure nanometer silver per kilometer of activated carbon; vacuum dipping; centrifugal dehydration; drying; and pressing for molding. The activated carbon is added with nanometer silver particles, so the present invention has the functions of kill bacterial virus, removing peculiar smell, and the like, and realizes the efficacy that one plus one is more than two, and the present invention can not become invalid.

Description

technical field [0001] The invention relates to a filter activated carbon core, in particular to a nano silver filter activated carbon core and a manufacturing method thereof. Background technique [0002] The treatment of drinking water is a major event related to people's health. In the prior art, a very important part of the treatment of drinking water is to use activated carbon to filter the water. Activated carbon is an irregular powder or pellet with a porous structure. Shaped amorphous carbon, each gram of activated carbon has an average surface area of ​​about 1,000 square meters. Activated carbon has a strong adsorption capacity and can gather gases, vapors, liquids or dissolved substances and colloidal solids. However, the adsorption of activated carbon on substances is selective, non-polar substances are easier to adsorb than polar substances, so the absorption of polar substances is limited; in addition, the adsorption of homologues generally increases with the i...
