Description
Technical field
The invention belongs to environmental technology fields, and in particular to a kind of indoor air purification particle and preparation method thereof.
Background technology
Along with industry and rapid development of economy, environmental pollution becomes the social concern that the mankind pay close attention to jointly.By automobile
Main species one of of the atmosphere pollution of the formation such as the foul gas in tail gas, industrial fumes, living environment as environmental pollution,
The attention of scientific circles is received, many scientists are dedicated to the research of waste gas pollution control and treatment.Material for air purification is a kind of by physics, change
The material of harmful substance in etc. modes adsorption-decomposition function air is a kind of effectively control air pollution using material for air purification
The mode in source.
Indoor air purification material and technology include mainly following several classes at present：（1）With activated carbon, diatom is pure, nanometer mine
Crystalline substance, clay, molecular sieve etc. are the porous media of representative, and mainly based on absorption, but adsorption capacity is smaller, and because its is right
There is adsorption capacity in most of substance, lack adsorptive selectivity, to the pollutant of low concentration substantially without removal effect, be easy full
With, so being just easy to lose adsorption capacity, and when temperature and humidity change, it can also cause desorption, i.e., it is porous
In a certain component external and internal pressure it is different, and so that pollutant is released from porous media, causes secondary pollution；（2）With
HEPA, activated carbon（Modified activated carbon）, photocatalyst（Titanium dioxide）, one or more of anion etc. be combined into air purification
Filter core（Filter membrane）High efficiency filter, pollutant absorption, photocatalysis Decomposition purification and anion are carried out to air to occur to improve air matter
Amount is placed in for example, by using titanium dioxide ultrafine powder in the purification channel of metal mesh and filter cloth composition, or with binder by titanium dioxide
Titanium valve is fixed on the carriers such as glass, ceramics, this has a good clean-up effect to solid granulates pollutant, then to cumulative bad or
Just person of modern times's clean-up effect of low concentration gaseous pollutant does not anticipate, and main cause is to make response area because of the self aggregation of superfine powder
It reduces, and air passage rates is reduced due to retardation of the superfine powder in purification channel, air purification
Efficiency reduces, purification speed is slow, purification is not thorough, the drawbacks such as limited, power consumption consumptive material that there is also usable floor areas；（3）Photocatalytic method,
This method has to carry out catalysis reaction under ultraviolet irradiation, and transformation efficiency is low, and use environment is restricted, light
The titanium dioxide needs of catalyst are reacted under the irradiation of ultraviolet light or fluorescent lamp, this increases the use of electricity significantly,
Power consumption consumptive material；（4）Precious metal catalyst method, this method are mainly that formaldehyde is carried out oxygen by your gold such as silver, platinum, palladium as catalyst
Change, the general cost of noble metal catalyst is higher, and will appear catalyst poisoning phenomenon, makes catalyst failure.In consideration of it,
The material for air purification that a kind of absorption property is good, inexpensive, usage time is long, purifying rate is high is researched and developed, there is good market to answer
Use foreground.
