Abstract
The invention discloses a filter material for removing aldehydes. The main bodies of the filter material are porous or fluffy carriers and amines are loaded on the carriers. The filter material can effectively remove various aldehydes under various conditions, does not produce secondary pollution and has certain effect on removing other harmful substances. The filter material has simple and reliable preparation process and low production cost and can be applied in large scale. The filter material can be manufactured into aldehydes-removing filters suitable for various devices by cutting, folding, punching, filling and other conventional procedures and has wide application range.
Description
Technical field
The present invention relates to a kind of aldehydes removal material, the filtering material of particularly a kind of ability wide spectrum aldehydes removal.
Background technology
Aldehydes, particularly formaldehyde are widely used in various decorative panels, furniture, the binding agent.Be the main indoor pollution sources in new decorated house, office, meeting room, hotel, karaoke chamber and furniture market, building materials market.
Existing aldehydes removal material for load photocatalyst on carrier, through the catalysis of photocatalyst, is degraded to harmless water and carbon dioxide with aldehydes.This type of aldehydes removal manufacture of materials complex process, the material require that makes satisfies certain condition, could the catalytic degradation aldehydes like certain illumination.But in the indoor environment, generally all be difficult to satisfy this condition, this causes the aldehydes removal effect of this aldehydes removal material extremely limited.
In addition, existing aldehydes removal material, only PARA FORMALDEHYDE PRILLS(91,95) has removal or inhibitory action preferably, and to other aldehydes, like acetaldehyde, its removal effect is relatively poor.
Summary of the invention
The object of the present invention is to provide a kind of filtering material that can effectively remove various aldehydes.
Technical scheme that the present invention takes is:
A kind of filter material for removing aldehydes, its main body are cellular or puffy carrier, and load has amine on the carrier.
Carrier comprises active carbon, porous ceramics piece, activated alumina, zeolite, fiber.
The preferred triethanolamine of amine, dicyandiamide, 3,3 ' diethyl-4,4 ' diaminodiphenyl-methane, 1,2 propane diamine, poly amic acid, alkene amine.
Filter material for removing aldehydes of the present invention can effectively be removed various aldehydes, non-secondary pollution under multiple condition.In addition, material of the present invention also has certain removal effect to other harmful substances.
Filter material for removing aldehydes of the present invention, preparation technology is simple, reliable, and production cost is low, but large-scale application.
Filter material for removing aldehydes of the present invention, through cut, fold, conventional operation such as die-cut, filling, can be made into the aldehydes removal filter that is applicable to various device.
The specific embodiment
A kind of filter material for removing aldehydes, its main body are cellular or puffy carrier, and load has amine on the carrier.
Carrier comprises active carbon, porous ceramics piece, activated alumina, zeolite, fiber.
The preferred triethanolamine of amine, dicyandiamide, 3,3 ' diethyl-4,4 ' diaminodiphenyl-methane, 1,2 propane diamine, poly amic acid, alkene amine.Various amine substances both can use separately, also can mix use.
Below in conjunction with embodiment, further specify the present invention.
Embodiment 1
Triethanolamine with 45% mixes with 55% poly amic acid, and add on the activated carbon granule through spraying method the back that stirs, and obtains filter material for removing aldehydes after drying.
Embodiment 2
Triethanolamine with 30%, 70% triethylene tetramine mix, and stir the back brushing on the porous ceramics piece, obtain filter material for removing aldehydes after drying.
Embodiment 3
Use 3,3 ' diethyl-4,4 ' diaminodiphenyl-methane to soak string, obtain filter material for removing aldehydes after drying.
Embodiment 4
Use 1,2 propane diamine, soak string, obtain filter material for removing aldehydes after drying.
The filter material for removing aldehydes of embodiment 1 is filled in the paper wasp nest, is made into the aldehydes removal filter that is fit to the air cleaner installation specification, through detecting, the formaldehyde clearance is 99% after 30 minutes, and the acetaldehyde clearance is 95%.
The filter material for removing aldehydes of embodiment 3 is folded, cuts, be made into the aldehydes removal filter that is fit to the air-conditioning installation specification, through detecting, the formaldehyde clearance is 100% after 30 minutes, and the acetaldehyde clearance is 94%.
Can know that by above test filter material for removing aldehydes of the present invention has good aldehydes removal effect, can effectively remove multiple aldehyde material.
Claims (1)
