Abstract
The utility model discloses a kind of air purifier filtration core, including micro- voided polytetrafluoroethylene film and mesh fabric, micro- voided polytetrafluoroethylene film is adhesively fixed with mesh fabric.The utility model has advantages below：Using micro- voided polytetrafluoroethylene film that average pore size is 0.2 micron, with reference to the composite bed that constitutes of mesh fabric of large aperture, be used as filtering element for air purifier, can long-term use, filter efficiency is up to more than 99%.
Description
Technical field
The utility model is related to air cleaning facility technical field, especially a kind of air purifier filtration core.
Background technology
The existing filtering material HEPA materials that are all for being widely used in air purifier（That is high efficiency particle air filter）
It is made, most common of which material has PP filter paper, compound PET filter paper, melt-blown terylene non-woven fabric and melt-blown glass fibre.These
The major defect of material is the Electrostatic Absorption particulate matter for relying on fiber roots, can be ineffective when use environment humidity is larger,
Because its aperture is big, air drag is small, it is ensured that the air output in certain hour, but on disposable intercepting efficiency, it is impossible to
Reach more than 95%.After certain hour（It is general to be no longer than three months）Electrostatic interaction gradually fails, until not working.
Utility model content
The utility model in view of the shortcomings of the prior art, proposes a kind of air purifier filtration core, simple structure, filtering
Effect is good.
In order to realize above-mentioned utility model purpose, the utility model provides following technical scheme：A kind of air purifier is used
Filtration core, including micro- voided polytetrafluoroethylene film and mesh fabric, micro- voided polytetrafluoroethylene film are adhesively fixed with mesh fabric.
Further, the mesh fabric is provided with two-layer, and the both sides of micro- voided polytetrafluoroethylene film are bonded in respectively.
Further, the mesh fabric includes terylene mesh, nylon net cloth, polyamide fibre screen cloth or terylene non-woven fabric.
Further, the aperture of micro- voided polytetrafluoroethylene film is 0.16~0.22 micron.
Compared with prior art, the utility model has advantages below：It is 0.2 micron micro- porous poly- using average pore size
Tetrafluoroethylene, with reference to the composite bed that constitutes of mesh fabric of large aperture, is used as filtering element for air purifier, can long-term use,
Filter efficiency is up to more than 99%.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model air purifier filtration core；
Fig. 2 is another structural representation of the utility model air purifier filtration core.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings, the description of this part be only it is exemplary and explanatory,
There should not be any restriction effect to protection domain of the present utility model.
As shown in figure 1, a kind of air purifier filtration core, is two-layer composite, ground floor is micro- porous polytetrafluoro
Ethene（ePTFE）The raw materials such as film 1, second layer mesh fabric 2, the screen cloth being made into including terylene, nylon, polyamide fibre etc., or terylene
The non-woven material being made.It is bonded using PUR between two-layer.
As shown in Fig. 2 a kind of air purifier filtration core, is three layers of laminating material, ground floor is mesh fabric 2, bag
Include the screen cloth that terylene, nylon, polyamide fibre etc. are made into, or the non-woven material that the raw material such as terylene is made, the second layer is ePTFE membrane 1, the
The non-woven material that the raw materials such as Three-layer mesh fabric 2, the screen cloth being made into including terylene, nylon, polyamide fibre etc., or terylene are made.
EPTFE membrane therein 1, with polytetrafluoroethylene (PTFE) as raw material, using special process, through calendering, extrusion, biaxial tension,
High-temperature shaping etc. is prepared from, and film surface is covered with fibrillation shape micropore, and porosity more than 90%, each square inch has up to 90
Hundred million micropores, with excellent microparticle filter effect, are widely used in the neck such as pharmacy, biochemistry, microelectronics and laboratory consumptive material
Domain.Because its aperture averaging is at 0.2 micron, so how many PM2.5 particulate matters big absolutely（General particle diameter 0.5 to 1.0 micron it
Between particulate matter account for more than 98%）, and ePTFE membrane has high temperature resistant, low temperature resistant, erosion-resisting good physical behavior in itself, so
The filtration core of this product can be with long-term use, without changing.
The preparation method of the utility model double-layer structure product is as follows：
1st, PUR is melted to 75 to 95 DEG C；
2nd, upper strata, PUR and layer fabric or non-woven material are compressed with laminating machine again and is fit together；
3rd, the material that will be posted is shelved 48 hours among natural air and carries out curing process.
The product of three-layer composite structure, is on the basis of two-layer structure product, by the ePTFE of the double layer material being cured
Face, PUR and layer fabric or non-woven material are compressed and fit together, and are shelved among natural air 48 hours and are solidified
Treatment, that is, obtain the product of three-layer composite structure.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
