Description

A kind of method for treating indoor air pollution

Technical field

The present invention relates to a kind of air purification method, particularly a kind of method that room air pollution is administered,

Background technology

As everyone knows, behind the new finishing in house, the harmful substances such as formaldehyde, benzene, xylene and ammonia that from finishing material, slowly discharge often make room air pollution exceed standard.For this type of treating indoor air pollution, more effective at present way is to adopt photocatalyst new technique, degradable indoor formaldehyde, benzene, ammonia and other organic pollutions.

Photocatalyst is a kind of with nanoscale TiO₂(titanium dioxide) is the photosemiconductor material with photo-catalysis function of representative; It is under the irradiation of light, and self does not change, and but can promote chemical reaction; Under aerial oxygen of organic pollution that is adsorbed on the surface and hydrone combined effect; Carry out oxidation-reduction reaction, promote organic pollution to imitate decomposition by force, final degradation is harmless carbon dioxide and hydrone.

For oxidation-reduction reaction is taken place with being more prone to, must increase the contact area of photocatalyst material and air as far as possible.Administering air pollution at the indoor application photocatalyst, generally is that it is sprayed to indoor wall, ceiling or indoor furniture body surface.But in implementation process; Have following two defectives to be difficult to avoid: the one, the outermost layer that photocatalyst material must be sprayed on object could guarantee the direct ingress of air ofnanomorphic TiO 2 particles; So just relate to the secondary construction, wait until and just can carry out the photocatalytic spray construction after interior decoration is completed; The 2nd, existing photocatalyst kind is a lot, varies in color, and generally is milky or translucent; Common milky concentration is higher; Have stronger absorbability and OR photocatalysis, but this type of color is not necessarily compatible mutually with finishing color or furniture color, and the photocatalyst decontamination cycle is longer; Generally will work some months even for many years, being sprayed directly into indoor existing object surface may not be welcome.

With this simultaneously, when general house decoration was moved in, the user can buy like white goods products such as refrigerator, air-conditioning, colour TV, washing machinees.After the household electronic products of new purchase was sealed off use, its extranal packing box (being generally carton) had basically no reserve value because of floor space is big, generally just abandons or sell salvage station.

Summary of the invention
