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
The present invention is a kind of filtration of active charcoal core, particularly a kind of nano silver filtering activated carbon core and preparation method.
Background technology
The processing of drinking water is to be related to the healthy major issue of people, in the prior art, the processing of drinking water, a very important link is to utilize activated carbon that water is filtered, activated carbon is the random powdery of loose structure or the unsetting carbon of ball shape, every gram activated carbon on average has 1,000 square metres surface area approximately, and activated carbon has strong adsorption capacity, can assemble gas, steam, liquid or dissolved substances and colloidal solids.But activated carbon is selectively to the absorption of material, and apolar substance is easy to absorption than polar substances, so the absorption of polar substances just is restricted; In addition, generally be that increase with boiling point increases to absorption in the homologue, so the absorption of the lower homologue of boiling point also is restricted.
Summary of the invention
The objective of the invention is influences the defective of filter effect in order to overcome activated carbon in the limitation aspect the absorption, invent the nano silver filtering carbon core that a kind of method of adding Nano Silver in activated carbon improves strainability.It is neutral that Nano Silver becomes in water, acid and alkali-resistance, and salt tolerant, to the good stability of light and heat, avirulence, stable in properties does not produce depositing silver, and active superpower, tissue permeability is extremely strong, uvioresistant, chemical characteristic is stable.Add Nano Silver in activated carbon after, its product is a nano silver filtering carbon core, kill bacteria and virus are removed peculiar smell etc., has realized one-plus-one greater than two effect, and can not lose efficacy.
The objective of the invention is to realize as follows: described nano silver filtering carbon core is combined by activated carbon and Nano Silver, and concrete moulding process is as follows:
One. select materials:
The granularity of activated carbon: 30-60 order;
The granularity of Nano Silver: 12-35nm;
Two. the pure Nano Silver of the proportioning of Nano Silver and activated carbon: 0.5-8g/per kilogram activated carbon;
Three. Nano Silver is mixed earlier with running water or deionized water and stir, activated carbon is poured in the vacuum tank, again nano-silver water solution is poured into and carried out vacuum impregnation in the vacuum tank, pour how much being as the criterion of nano-silver water solution into the submergence activated carbon, dip time overflows with no bubble in the water and is as the criterion, and its vacuum is＜=760 millimetress of mercury;
Four. centrifugal dehydration;
Five. under 190-210 ℃ of condition, dry;
Six. under 20 ℃～200 ℃ conditions, be pressed by selected mould;
Seven. carbon core outward appearance
The carbon core outward appearance that made comes out is according to the actual requirements that generally speaking, its outward appearance is a cylindrical body and fixed.
Good effect of the present invention is as follows: owing to added nano-Ag particles in activated carbon, so the present invention has kill bacteria virus, removes function such as peculiar smell, realized one-plus-one greater than two effect, and can not lose efficacy.

Four. centrifugal dehydration;
Five. under 200 ℃ of conditions, dry;
Six. under 100 ℃～20 ℃ conditions, be pressed by selected mould;
Seven. carbon core outward appearance:
The carbon core outward appearance that made comes out is according to the actual requirements that generally speaking, its outward appearance is a cylindrical body and fixed, as:
High 500mm;
Diameter 25mm;
Internal diameter 10mm.
