Abstract
The invention belongs to technical field of hardware, are related to filter cotton technical field, in particular to the air filtration cotton of the high-strength absorption of a kind of containing diatomite.Including filter cotton ontology, filter cotton ontology includes entering the wind surface layer and outlet air surface layer and the fire-retardant stratum reticulare being arranged between air inlet surface layer and outlet air surface layer, the first synthetic fiber layer, activated carbon fiber layers, the second synthetic fiber layer, antistatic layer, the flame-retardant and anti-static performance of filter cotton is improved, while the setting of multi-layer compound structure also improves the structural strength of filter cotton；Diatomite synthetic fiber layer, PM2.5 can be screened out from synthetic fiber layer to play the role of surface filtration, harmful polar molecule in the pernicious gas to suspend in air can also be trapped in synthetic fibers layer surface and channel, reach gas solid separation, purify air, increase adsorption specific surface area, improves purification filtering effect and absorption property；Synthetic fiber layer includes two layers and density is different, further improves filtration, purification effect and absorption property.
Description
Technical field
The invention belongs to technical field of hardware, be related to filter cotton technical field, in particular to a kind of containing diatomite it is high-strength
The air filtration cotton of absorption.
Background technique
Contain a large amount of dust particle (such as dust, flue dust, powder) in the air that we live, the floating of these dust particles
In air, these dust particles are usually adsorbed with a large amount of pernicious gas, liquid or metallic element, these dust particles are often
It can cause various respiratory illness as respiration is inhaled into lung or is adhered on bronchial tube wall, cause lung
Fibrosis lesion occurs for tissue, hardens lung tissue gradually, loses normal respiratory function, and cause related disease.Filter cotton
Can it is effective cross air filtering in dust particles, achieve the effect that purify air, guarantee sucking lung air cleanliness.
Existing filter cotton filter effect is limited, cannot effectively cross the harmful substance in air filtering, functional relatively simple, is unable to satisfy
The actual demand in market lacks the market competitiveness.
Summary of the invention
The purpose of invention: the present invention provides a kind of air filtration cottons of the high-strength absorption of containing diatomite.
Technical solution: in order to achieve the goal above, the invention discloses a kind of air mistakes of the high-strength absorption of containing diatomite
Filter pulp, including filter cotton ontology, the filter cotton ontology are multi-layer compound structure, air inlet surface layer and the other end including one end
Outlet air surface layer is successively arranged fire-retardant stratum reticulare, the first synthetic fiber layer, activated carbon fibre to outlet air surface layer direction by air inlet surface layer
