Description
Technical field
The invention belongs to air purification fields, and in particular to a kind of preparation method of air cleaning sponge.
Background technique
This problem of indoor pollution causes the attention of people in recent years, and room air pollution refers to be led due to various reasons
Harmful substance is exceeded in the room air of cause, and then influences the indoor environmental pollution behavior of human health.Nuisance include formaldehyde,
Benzene, ammonia, radioactive radon etc..As pollution level is aggravated, human body can generate inferior health reaction or even threaten life security.It is day
One of human body harm that benefit is taken seriously.
People daily an average of about 80% or more time spend indoors.It is more existing with life style with producing
Dai Hua, more work and sports entertainment can all carry out indoors, and shopping need not also go into the street daily, suitable indoor small
Weather makes people that need not often arrive outdoor de-regulation fuel factor, in this way, the indoor activity time of people with regard to more, even as high as
93% or more.Therefore, indoor air quality just seems more closely more important to the relationship of human health.Indoor pollution source is very
It is more, such as wallpaper, family property, furniture, solid wooden floor board etc., although the concentration of indoor pollutant is often lower, when due to contact
Between it is very long, therefore its accumulate exposure it is very high.Especially the elderly, young, sick, disabled and other frail people, Abwehrkraft des Koepers be lower, outdoor activities
Chance is less, and therefore, the fine or not relationship with them of indoor air quality is particularly important.In addition to indoor pollution, in automobile
Automotive air pollution also can not be ignored, and the toxic and harmful gas such as formaldehyde, toluene, ammonia that new car is discharged are often exceeded.
For indoor and auto-pollution gas purification, a product of comparative maturity is air purifier, air at present
The strainer that clarifier uses is active carbon filling filter screen or folder carbon cloth filter screen.The scavenging material that filled type filter screen uses
It is mostly column-shaped active carbon, column-shaped active carbon is can not to play activity completely by the way that Powdered Activated Carbon kneading to be granulated
The high-specific surface area of charcoal and high porosity, thus purification efficiency is caused to reduce.What folder carbon cloth filter screen used is mostly 60 mesh
The active carbon particle of left and right is got up by upper layer and lower layer electrostatic cotton cladding, and every square metre of activated carbon content is few, and windage mistake
Greatly, clean-up effect is influenced.
Summary of the invention
To overcome existing active carbon to fill, filter screen column-shaped active carbon hole utilization rate is not high and folder carbon cloth strainer is active
Carbon content lacks the big disadvantage of windage, the primary purpose of the present invention is that providing a kind of preparation method of air cleaning sponge.The sky
Gas, which purifies sponge PARA FORMALDEHYDE PRILLS(91,95), toluene, ammonia, TVOC and particulate matter, has good clean-up effect, is giving full play to active carbon
While detergent power, there is smaller windage.

0.62mg/m3、0.54mg/m3、0.47mg/m3、0.43mg/m3、0.40mg/m3；Windage is 3.0Pa.
Comparative example 2: cutting length × width × height=30cm × 20cm × 3cm folder carbon cloth 20, and every phosphorus content is about 5g,
It is as shown in Figure 3 to press from both sides carbon cloth.PARA FORMALDEHYDE PRILLS(91,95), the purification efficiency of toluene and windage are tested under the conditions of same as Example 1.It adopts
With gas chromatography test result show the sponge in 10min, 20min, 30min, 40min, 50min, 60min, formaldehyde
Concentration is respectively by 1.00mg/m3Drop to 0.92mg/m3、0.85mg/m3、0.81mg/m3、0.77mg/m3、0.76mg/m3、
0.75mg/m3；The concentration of toluene is respectively by 1.00mg/m3Drop to 0.93mg/m3、0.88mg/m3、0.84mg/m3、0.83mg/m3、
0.81mg/m3、0.78mg/m3；Windage is 18.5Pa.
The above air cleaning sponge, filled type filter screen, press from both sides three kinds of filter screens of carbon cloth formaldehyde removal rate compare such as Fig. 4 institute
Show, formaldehyde removal rate is air cleaning sponge strainer, active carbon filled type strainer, folder respectively from high to low as we can see from the figure
Carbon cloth filter screen, wherein for air cleaning sponge filter screen in 60min, concentration of formaldehyde is from 1.00mg/m3Fall below 0.04mg/m3,
Removal rate has reached 96%, significantly larger than active carbon filled type strainer and folder carbon cloth filter screen.
The above air cleaning sponge, filled type filter screen, press from both sides three kinds of filter screens of carbon cloth toluene removal rate compare such as Fig. 5 institute
Show, toluene removal rate is air cleaning sponge strainer, activity respectively from high to low as we can see from the figure
Charcoal filled type strainer, folder carbon cloth filter screen, wherein for air cleaning sponge filter screen in 60min, toluene concentration is from 1.00mg/m3
Drop to 0.07mg/m3, removal rate reached 93%, significantly larger than active carbon filled type strainer and folder carbon cloth filter screen.
The above air cleaning sponge (embodiment 1), filled type filter screen (comparative example 1), folder carbon cloth (comparative example 2) three kinds of mistakes
The windage of strainer compares as shown in fig. 6, windage size is folder carbon cloth filter screen, air respectively from high to low as we can see from the figure
Purify sponge strainer, active carbon filled type strainer.The windage for wherein pressing from both sides carbon cloth filter screen has reached 18.5Pa, therefore air can not
Quickly circulation, thus its clean-up effect is poor；Column-shaped active carbon filled type strainer windage is minimum, and only 3.0Pa, air can be fast
Speed flowing, but since column-shaped active carbon is unable to give full play the suction-operated of active carbon, thus influence its clean-up effect；This hair
The windage of the bright air cleaning sponge is 4.5Pa, and air can normally circulate, because active carbon powder is attached on sponge, sponge
Pore structure greatly increase the contact area of active carbon, and there is lesser windage, thus there is very high clean-up effect.
