In view of the harm and pollution status of formaldehyde, a plurality of methods for treating formaldehyde pollution appear in the market at present, but the effect is not ideal. The following were used:
1. an air purifier: its adsorption filter screen is small in volume, easy to saturate, high in cost and its effect is not ideal.
2. Activated carbon adsorption: the effect is slow, and the absorption can be saturated after a certain degree, and the air conditioner needs to be replaced or taken out for airing outdoors. If the treatment is not timely, the harmful gases such as the adsorbed formaldehyde and the like are released again to cause secondary pollution.
3. Gas catalyst treatment: the gas catalyst is mainly chlorine dioxide (CLO2), a strong oxidant, and has strong corrosivity. It has certain bactericidal effect, and can treat some formaldehyde in air with strong oxidizing property, but its effect is not lasting and is easy to rebound. But also has corrosiveness on furniture, cloth art and metal decorating parts, and is irretrievable.
4. There are many technical patents in China, such as Chinese patent CN201210279279.2 formaldehyde pollution removal catalyst and CN103613129A nanometer titanium dioxide sol, the main component is titanium dioxide, because titanium dioxide is ultraviolet light catalyst, under natural light or no light condition, the formaldehyde removal effect is very limited, has application limitation; the inventor intends to seal the surface of pollutants by a film forming method after the reaction of titanium dioxide and ultraviolet rays and prevent formaldehyde from being released outwards, and the inventor cannot meet the requirement of film forming due to the reasons and causes the pollution to rebound quickly after treatment.
Therefore, there is a need for improvements in the prior art to avoid the disadvantages of the prior art.
