A kind of deodorizing composition and application thereofTechnical field
The present invention relates to technical field of air purification, be specifically related to a kind of deodorizing composition and application thereof.
Background technology
At present, the product that indoor pollution is administered mainly has taste removal bag, aerosol type eliminating smell agent, air purifier and all kinds of placementType aromatising prods.Taste removal bag mainly utilizes activated carbon, bamboo charcoal, mineral etc. to have the function of adsorbing contaminant, with ventilative nonwovenThese adsorbing materials packed by cloth.Owing to different non-woven fabrics air permeable effects is also same, before the content ensureing packaging does not spillsPutting, even if using best non-woven fabrics, its air penetrability also only has 60%, so, the working substance in non-woven fabrics and airIn the contact range of odor molecules extremely limited, have impact on the effect of use.Aerosol type eliminating smell agent is to use the mode sprayed,Action effect is direct, but belongs to instant taste removal product, and effect is without long-lasting, and the drop after being atomized during spraying stopsThe most easily sucked by human body, affect the health of people.Air purifier is the main product of current indoor purifying, mainDynamic purification, efficiency height, but air purifier is expensive, and need electric power, there is potential safety hazard during use,Most of air purifiers also need to timing and change filter element, use trouble.Placed type aromatising prods mainly has gel-like, liquidVolatilization class, the mode of this series products many employings flavouring carries out taste removal, can be effectively improved environmental odors acceptance, but can not be realGo to eliminate the unusual smell.
In sum, in existing indoor pollution improvement field, lack a kind of cheap, can adsorption-decomposition function abnormal flavour, taste removalEffect is direct, the simple long-acting taste removal product of occupation mode.
Summary of the invention
It is an object of the invention to overcome the defect of above-mentioned prior art, it is provided that a kind of deodorizing composition, this deodorizing composition energyEnough adsorption-decomposition function abnormal flavour, taste removal effect is the most long-acting.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of deodorizing composition, it includes following components by weight: photocatalyst 3～15 parts, anion powder 3～10Part, natural smell-removing material 1～10 parts, plant extract 0.5～2 parts, antibacterial 0.5～1 part, essence 0～1 part.
