Description
Technical field
The invention belongs to field of Environment Protection, and in particular to a kind of purification of air adsorbent, further relate to the system of above-mentioned adsorbent
Preparation Method.
Background technology
With the enhancing of people's environmental consciousness, the raising of the special air quality of environment is increasingly paid attention to.Room air pollution
Mostly come from the following aspects：Finishing pollution, atmosphere pollution.
In fitment process, conventional finishing material, such as paint, coating, flooring laminate, wallpaper, glued board, plastics, class polychlorostyrene
Ethene（PVC）Plate, insulation material, and interior artificial board, the various glued thick chinas of such as lumber core, the furniture of density board and U.S.
Art works etc., it can all discharge VOC.Identified 350 kinds at present, using arene and fat hydrocarbon as
It is main.The pollution phase of different ornament materials is also not quite similar.Relevant expert's these three conventional decoration materials to flooring laminate, coating and wallpaper
Material has carried out tracking measurement, and research finds that the pollution phase of these three materials is respectively 1 month, 2 months and 3 months.Indoor volatilization
Property organic compound can stimulate skin, mucous membrane and nervous system, produce that a series of allergic symptoms and neurobehavioral are abnormal, and pathology is ground
Study carefully and find that person under inspection's tear film stability reduces, tear cell component changes, and albumin content increases, and pharynx nasalis is congested, deposits
In a large amount of inflammatory cells.Animal experiment shows there is potential mutagenesis, teratogenesis, carcinogenicity.
Atmosphere pollution is mainly haze pollution, and haze is the mixture of mist and haze, and during morning and evening high humidity, the composition of mist is more.In vain
Its humidity hour, haze occupy the main force, and relative humidity is between 80% to 90%.Wherein mist is natural weather phenomenon, steam in air
The generative forces of heaven and earth.It is although overall nontoxic using dust as the nuclei of condensation；The core substance of haze is suspended in cigarette, dust in air
Deng material, relative air humidity is less than 80%, yellowish.Gas can be directly entered and be adhered to human body lower respiratory tract and the lobe of the lung
In, there is injury to health.The formation of haze weather is mainly artificial environmental pollution, along with temperature is low, wind is small etc.
Natural conditions cause pollutant to be not easy to spread.After haze enters human body, easily accumulated in the lung of human body, it is difficult to discharge, for
The lung organ of human body causes irreversible damage.
Therefore, it is necessary to invent a kind of purification of air adsorbent for being especially adapted for use in interior.
The content of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of good purification, can effectively absorb various
