Abstract
The invention relates to a method for preparing an activated carbon fiber filter core, and the method comprises the following steps: activated carbon fiber which carries with an bactericide is mixed with activated carbon after being crushed or ground, and then is blended with a hot melting binder, and beating is carried out in water; the beated material is put in a suction pool for being stirred, and the stirring is even; suction mold is carried out in the internal mold of an aspirator; the moulded activated carbon fiber filter core is put into an oven for drying, and the finished product is obtained after melting; the activated carbon fiber filter core prepared by the invention through the moulding mode of the internal mold arranged on the aspirator has the advantages that the fiber bonding is tight, the content of the binder is lower, and the specific surface area of the activated carbon fiber is not influenced; the bactericide is loaded on the activated carbon fiber, thereby not only restraining the growth of bacteria and algae on the filter core, but also killing the bacteria and the algae in water, and sterilization ions such as silver, copper, etc. cannot cause shedding easily, thereby greatly improving the purity and the germicidal efficacy of the activated carbon fiber.
Description
Technical field
The present invention relates to a kind of product and preparation method who is used for drinking water and the purification of other clean water, medicine, wine brewing, food decolouring, organic solvent adsorption filtration, particularly a kind of preparation method of activated carbon fibre filtering core.
Background technology

The moulding process that at present domestic activated carbon or activated carbon fiber filter core mainly adopt mold pressing or winding, the shortcoming of compression molding is that the filter core binder content is excessive, can obviously reduce the specific area of activated carbon or activated carbon fiber like this, make its absorption, the performance of decolouring, eliminate the unusual smell reduces greatly.The activated carbon fiber filter core that adopts Wrapping formed mode to make, fiber is in conjunction with very lax, and the slit between activated carbon fiber is big, can reduce the adsorption efficiency to the poisonous and harmful substance in the water, and causes the growth of bacterium on the filter core during stopping using easily.
Summary of the invention
Be to solve the problem that prior art exists, the purpose of this invention is to provide a kind of preparation method of new activated carbon fibre filtering core, this method can effectively suppress bacterium on the filter core, algae grows, and kills bacterium and algae in the water, good purification.
For achieving the above object, the present invention is by the following technical solutions:
A kind of preparation method of activated carbon fibre filtering core, this method may further comprise the steps:
1) activated carbon fiber is pulverized, mixed with active carbon, the percentage by weight that described active carbon accounts for mixture is 0-80%; Mix with hot-melt adhesive then, pull an oar in water, the part by weight of water, activated carbon fiber mixture, hot-melt adhesive is 1000: (5-50): (0.1-2);
2) material after the making beating is put to the suction pond and is stirred, and stirs;
3) aspirator that will install inner mold is put into pond suction 1-50 minute, and activated carbon fibre filtering core moulding on the inner mold of aspirator proposes inner mold;
4) the activated carbon fiber filter core of moulding is put into baking oven dry, dry by the fire after molten finished product; Bake out temperature is 60-170 ℃, and the baking melting temperatur is 110-300 ℃.
Be loaded with the metal bactericide in the described activated carbon fiber.
The preparation method of described a kind of activated carbon fibre filtering core, the activated carbon fiber filter core of moulding put into baking oven dry, dry by the fire molten after, externally compound again one deck filter cloth.
Described hot-melt adhesive is polyethylene binder, polypropylene adhesive, polyamide binders or polyester adhesive.
Compared with prior art, the invention has the beneficial effects as follows: be provided with the molding mode of inner mold by aspirator, the activated carbon fibre filtering core fiber that makes is in conjunction with closely, and binder content is low, can not influence the specific area and the adsorption function of activated carbon fiber, and very little to the resistance of water; And on activated carbon fiber, be written into silver, copper, zinc plasma with sterilizing function, not only can suppress bacterium on the filter core, algae grows, can also kill bacterium and algae in the water, and sterilization ions such as silver, copper can not come off human body is damaged, the purification and the bactericidal effect of activated carbon fiber have been improved greatly, and at the inside and outside filter cloth that all is coated with through specially treated of filter core, but the above suspended particulate of elimination 5 μ m but also can prevent that the leakage of NACF from causing secondary pollution not only.
