Description
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to a nano oxygen catalyst air purifying agent and a preparation method thereof.
Background
In recent years, the air pollution problem is widely concerned by society, and the air quality spot inspection result of newly installed houses in China shows that the indoor air pollution degree is 2-3 times more serious than the outdoor air pollution degree, and even more than 100 times more serious than the outdoor air pollution degree under certain serious conditions.
The existing air purification methods are mainly classified into three types:
1. formaldehyde adsorption box, active carbon, diatom ooze and the like: the existing products such as various formaldehyde adsorption boxes, air purifiers, purified carbon and the like are essentially used for removing formaldehyde by utilizing air flow and passive adsorption, and because of the passive adsorption, the effect is very poor, and the formaldehyde adsorption purification effect on indoor decoration pollution is almost ineffective or very weak;
2. mechanical and electronic products such as an air purifier and a fresh air system: the purification effect is limited by the treatment capacity and the treatment area, the overall purification effect is not ideal, and the treatment cost, the use cost and the maintenance cost are high, such as power consumption, filter material replacement and the like; the comprehensive effect and the cost are not comparable to the effect and the cost of one-time treatment and lifelong thorough radical treatment of the nano oxygen catalyst technology;
3. photocatalyst technology and products: the formaldehyde-free spray coating is a product with relatively good purification effect in the market at present, can really play a certain purification effect under the condition of ultraviolet irradiation with specific wavelength, but can play a role in promoting the catalytic decomposition of formaldehyde under the condition of illumination due to the existence of the formaldehyde-free spray coating, cannot ensure the removal effect under the dark and dark conditions due to the technical limitation of the photocatalyst technology, has short effective period of the photocatalyst due to common spray coating construction, is a process of continuously releasing decorative formaldehyde, and has the longest release period of several years. Therefore, although the photocatalyst product has a certain effect, the photocatalyst product has obvious technical limitation, and the technical effects of continuous decontamination and thorough purification cannot be realized.
