Problems solved by technology

The disadvantage is that due to the characteristics of the product itself, it is difficult to achieve the effect of eliminating air pollution. Not only is the efficiency low, but it is also bulky and flammable, and once it is damaged by water, it will cause new pollution to the environment.

Abstract

The invention discloses a silicon-titanium composite filter element material which comprises a silicon-titanium composite filter element carrier and a catalyst which is carried by the silicon-titanium composite filter element carrier. The invention further discloses a preparation method and application of the silicon-titanium composite filter element material. Compared with a conventional pure activated carbon product, filtration and degradation of pollutants such as formaldehyde are relatively effectively improved, and the material has the advantages of high purification precision and good effects, is safe and reliable to human bodies, is free of secondary pollution, is particularly capable of continuously purifying pollutants, has the advantages of long action time and continuous action, and has the advantages of incombustibly and reuse as well.

Description

technical field [0001] The invention relates to the technical field of air purification. More specifically, it relates to a silicon-titanium composite filter material and its preparation method and application. Background technique [0002] Air pollution is a phenomenon that exists widely around us, especially when people are pursuing a beautiful life and the degree of industrialization has improved, they have fallen into the environment of polluted air without knowing it. Smog and dust, lingering cigarette smoke, kitchen fumes, and tens of thousands of mites and bacteria can be seen everywhere in the room. The air pollution in modern people's offices and living rooms has reached the point where it endangers environmental health. [0003] The existence of pollution affects people's physical and mental health while affecting the environment. At present, most of the traditional air purification filter materials are filter materials composed of activated carbon and other prod...
