Air filtering cotton containing diatomite and with strong adsorptivity

Abstract

The invention belongs to the technical field of hardware, relates to the technical field of filtering cotton and particularly relates to air filtering cotton containing diatomite and with strong adsorptivity. The air filtering cotton comprises a filtering cotton body, wherein the filtering cotton body comprises an air inlet surface layer and an air outlet surface layer as well as a flame-retardantnet layer, a first synthetic fiber, an active-carbon fiber layer, a second synthetic fiber layer and an antistatic layer which are arranged between the air inlet surface layer and the air outlet surface layer, and meanwhile, by arrangement of the multilayer composite structure, the structural strength of the filtering cotton is also improved; the fiber layers are synthesized by diatomite, so thatPM2.5 can be sieved from the synthesized fiber layers to play a role in surface filtration, harmful polar molecules in the harmful gases suspending in the air also can be intercepted in the surfacesand ducts of the synthesized fiber layers so as to achieve gas-solid separation, purify the air, enlarge the specific surface area of absorption and improve the purifying and filtering effect and theabsorbing performance; two layers of synthesized fiber layers are arranged and are different in density, so that the filtering and purifying effects and the absorbing performance are further improved.

Description

technical field [0001] The invention belongs to the technical field of hardware and relates to the technical field of filter cotton, in particular to a high-strength adsorption air filter cotton containing diatomite. Background technique [0002] The air we live in contains a large number of dust particles (such as dust, smoke, powder, etc.), these dust particles are floating in the air, these dust particles usually adsorb a large amount of harmful gases, liquids or metal elements, these dust particles often with Respiration is inhaled into the lungs or adheres to the wall of the bronchi, causing various respiratory organ diseases, causing fibrosis in the lung tissue, gradually hardening the lung tissue, losing normal respiratory function, and causing related diseases. The filter cotton can effectively filter the dust particles in the air, achieve the effect of purifying the air, and ensure the cleanliness of the air inhaled into the lungs. The existing filter cotton has li...

AI Technical Summary

Problems solved by technology

The existing filter cotton has limited filtering effect, cannot effectively filter harmful substances in the air, has relatively simple functions, cannot meet the actual needs of the market, and lacks market competitiveness
