Abstract
The invention discloses a kind of laminating base fabric dust catcher filtrates, including PTFE film layer is surface filtration layer, and PET base is backing material.It between PTFE film layer and the PET base of lower layer is bonded together by adhesive, laminating PTFE+PET base fabric media filtration resistance≤100Pa, filter efficiency >=95%.Filtering material of the invention can be used for dust catcher filtration art, have the characteristics that good filter effect and long service life, and be in process not in stripping phenomenon.
Description
Technical field
The present invention relates to a kind of high efficiency filter materials, more particularly to a kind of laminating filtrate of dust catcher.
Background technique
Air filting material is to intercept and adsorb dust by the fiber in material, has the function that purify air.Its
Material includes silk, synthetic fabrics, glass fabric, non-woven filter cloth (filter paper, filter felt, filtration liner), porous pottery
Porcelain etc. has been unable to meet people to noble and unsullied in filter efficiency and permeability though these materials have certain filter effect
The requirement of net air quality.
Polytetrafluoroethylene (PTFE) (PTFE) Film Filter Materials be by a kind of more micropores, thin-film material that is smooth, being easy to deashing, and it is good
Thermal stability and chemical stability, so that it is widely used in field of air filtration, and the polytetrafluoroethylene (PTFE) of hydrophobic
Filtration membrane can be combined with different substrate materials.Polytetrafluoroethylene film, which is easy to deashing property again, can increase the use longevity of device
Life.The purpose of the present invention is the excellent properties using polytetrafluoroethylene film, and substrate is compound prepares high efficiency, lower resistance
Air filting material.
Summary of the invention
The object of the present invention is to provide a kind of laminating dust catcher filtrates, high to solve the dedusting resistance in existing filtrate,
The problems such as service life is lower and not easy cleaning easy to fall off.
For the technical problem more than solving, the present invention provides a kind of laminating PTFE, PET dust catcher filtrate, by
PTFE film fits into filtering by adhesive with PET base as supporting layer, PTFE film layer as surface filtration layer, PET
Material.
PTFE film of the invention has the characteristics that the filtering of high-efficiency low-resistance, and the smooth easy-to-clean ash in surface.
The adhesive of the present invention is dual-component polyurethane adhesive, can be close by PTFE film layer and PET base copolyester
Fitting avoids the non-uniform problem of mixing that two kinds of different adhesives mixedly appear.
Preferably, the PTFE film layer with a thickness of 3-15 μm, pore diameter range is at 0.1-2 μm, the resistance of PTFE film
Power range 20-30Pa, filter efficiency 90-99.99%.
Preferably, the PET base is PET non-woven cloth, the grammes per square metre scope 30-120g/m2。
Preferably, the adhesive is dual-component polyurethane adhesive, the grammes per square metre scope 5-25g/ of adhesive is coated
m2。
Preferably, the laminating PTFE+PET base fabric filtrate is under 5.3cm/s flow velocity, and filtration resistance≤100Pa, mistake
Filter efficiency >=95%.
The beneficial effects of the present invention are:
The laminating prepared filtering material of PTFE+PET is mainly used in dust catcher by the present invention, has lower resistance and exceeds
Efficiency is filtered, and after repeatedly folding, improves its filter area and is not in stripping phenomenon, stable product quality, controllability
It is high.
The present invention be the method covered by glue by two kinds of Material claddings together, simple production process can carry out continuous
Batch production, meets the wilderness demand in market.
