Problems solved by technology

[0002] At present, most of the carbon-encapsulated non-woven filter materials produced in general industries have relatively low adsorption efficiency and high resistance, and some have basically no adsorption efficiency.
Patent 03231443.4 is a health-care composite fabric technology, which directly mixes the adhesive with activated carbon, and then composites it on the non-woven fabric as the base material by simple heating. The performance is not good, and it is easy to cause the activated carbon particles to be blocked by glue, resulting in low adsorption efficiency
Patent No. 200510049884.0 Activated carbon non-woven fabric and its manufacturing process. Although the activated carbon non-woven fabric produced by this process has relatively excellent adsorption performance, the production process is complicated and the product cost is relatively high.

Embodiment 1

[0010] Example 1: figure 1 What is shown is a filter material with only one composite layer between two layers of non-woven fabrics 1 and 4. First, the non-woven fabric 1 is coated with a layer of fibrous adhesive 2, and then 40-80 mesh activated carbon particles are sprinkled on the fibers. Granular activated carbon layer 3 is spread on the granular activated carbon layer 3, and then a layer of fibrous adhesive 2 is coated on the granular activated carbon layer 3, and the granular activated carbon layer 3 is wrapped between two layers of fibrous adhesive 2 to form a composite layer, and finally compounded Non-woven fabric 4 gets final product.

Embodiment 2

[0011] Example 2: figure 2 Shown is a filter material with two composite layers between two layers of non-woven fabrics 1 and 4. First, the non-woven fabric 1 is coated with a layer of fibrous adhesive 2, and then 40-80 mesh activated carbon particles are sprinkled on the filter material. Spread the first granular activated carbon layer 3 on the fibrous adhesive 2, then coat a layer of fibrous adhesive 2 on the granular activated carbon layer 3, and sprinkle 40-80 mesh activated carbon particles on this layer of fibrous adhesive 2. The second granular activated carbon layer 3 is formed, and a layer of fibrous adhesive 2 is coated on the second granular activated carbon layer, and the two granular activated carbon layers are respectively wrapped between two layers of fibrous adhesive to form a double composite layer. Non-woven fabric 4 gets final product.

[0012] The above-mentioned filter materials are combined with fibrous adhesives, which will not block activated carbon p...

Abstract

The invention discloses a filtering material, which more particularly relates to a material of an air filter applied to a central fan system; the material mainly includes an upper layer of non-woven fabrics and a lower layer of non-woven fabrics which are taken as base material as well as one or a plurality of composite layer(s) that is/are compounded between the upper and lower layers of non-woven fabrics; the material is characterized in that the composite layer(s) is/are composed of a granular activated carbon layer which is wrapped between two layers of nemaline cementing compound, and the granular activated carbon layer is formed by spreading independent activated carbon granules; the filtering material not only is not only efficient and has low resistivity, but also maintain the adsorption performance of the original activated carbon; furthermore, the hardness and stiffness of the general filtering material used for ventilation are kept, and the humdrum form of a chemical air filter is changed, so that the filtering material has the form of the general filtering material used for ventilation.

Description

1. Technical field [0001] The invention discloses a filter material, in particular to a filter material used in an air filter of a centralized ventilation system, and belongs to the field of air filter materials. 2. Background technology [0002] At present, most of the carbon-encapsulated non-woven fabric filter materials produced in general industries have relatively low adsorption efficiency and high resistance, and some have basically no adsorption efficiency. Patent 03231443.4 is a health-care composite fabric technology, which directly mixes the adhesive with activated carbon, and then composites it on the non-woven fabric as the base material by simple heating. The performance is not good, and it is easy to cause the activated carbon particles to be blocked by glue, resulting in low adsorption efficiency. Patent No. 200510049884.0 Activated carbon non-woven fabric and its manufacturing process. Although the activated carbon non-woven fabric produced by this process h...
