Background technology
Formaldehyde is a kind of Systematic toxin, and it can reduce the oxidation resistance of each organ of body, so as to cause organ
Oxidative damage, and concentration damage higher is more serious.Indoor formaldehyde pollution is mainly derived from furniture, building source, fabric, wood
Product filler, cosmetics, cleaning agent and personal belongings etc..At present, various methods are taken both at home and abroad to administer indoor formaldehyde
Pollution, these purification techniques summarize to get up mainly to have：Adsorption technology, photocatalysis technology, negative aeroion technology, chemistry neutralize skill
Art, ozonation technology, biotechnology, room-temperature catalytic oxidation technology, material sealing technique etc..It is each have their own excellent in these technologies
Point, such as photocatalysis technology can degrade indoor formaldehyde, but due to it indoors, can produce that the light of photocatalysis is less, and effect has
Limit；Be also good method using anion technology and ozone technology, but produced in making air proper amount of anion or
Ozone is to need suitable condition；The method that chemical neutralization technology and room-temperature catalytic oxidation have been, in general with regard to energy
Eliminate formaldehyde；It is a kind of preferable method using biotechnology, the effect of use condition and generation is all relatively limited；Using material
Sealing technique can not thoroughly completely cut off nuisance, and the duration for being reduced release nuisance can be more long；And use adsorption technology
It is one of current main flow purification techniques, it is widely used because being less subject to the influence of other conditions for using.
Conventional formaldehyde adsorbent is usually activated carbon, and Activated Carbon Production is relatively costly, and needs to use a large amount of forests
Resource or coal resources, therefore, the methyl aldehyde adsorption material for seeking to have replacement activated carbon is that have very important meaning.In recent years
Have shown that there is extremely strong fungistatic effect by the pyrophillite processed come many researchs in the world, and can the various harmful weights of absorption
Metal and pernicious gas.But in the prior art pyrophillite be with other various raw material complex roles with identical effect,
Single pyrophillite is adsorbed with toxic gas DeGrain, and prior art is to its complex disposal process, high cost, it is impossible to meet
Need.
