Description
Technical field
It the utility model is related to Nomex field, and in particular to a kind of Nomex of resistance to injection.
Background technology
Nomex is also referred to as needled filtering felt, is the lamellar composite type product weaved cotton cloth with nonwoven acupuncture nonwoven fabric, commonly uses
Make the cloth bag in sack cleaner.Sack cleaner is a kind of dry type dust filtration device, mainly utilizes the filtration of Nomex
Dusty gas is filtered, detention dust, is purified gas.Some industrial and mining enterprises are found when using sack cleaner
Its cloth bag breakage rate is high, causes cloth bag to rupture compared with conference mainly due to abrasion or wind speed, blast, so as to reduce pocket type
The service life of deduster, also greatly affected filter effect.Glass is strengthened or increased to existing Nomex using base fabric
The method of glass fiber improves the resistance to injection intensity of Nomex, but improve only intensity, and toughness can not be improved, and work as wind-force
Nomex can be deformed and bent when larger, so as to which breakage occur.
A kind of high intensity Nomex (Application No. 201620473488.4) of utility model patent, Nomex body are provided with
First stiffener, the second stiffener and the 3rd stiffener, Nomex body include the first filter layer, the second filter layer and the 3rd mistake
Filtering layer, the second filtering are placed between the first filter layer and the 3rd filter layer, and the first stiffener sequentially passes through the first filter layer, the
Two filter layers and the 3rd filter layer, the second stiffener sequentially pass through the first filter layer, the second filter layer and the 3rd filter layer.The reality
With it is new reached by setting up stiffener improve the purpose of Nomex intensity, but its pliability is poor, meeting when being blown through high intensity
There is disrepair phenomenon, service life is short.
Therefore a kind of intensity of urgent need offer is high, good toughness, resistance to injection, the Nomex of resistance to injection of high temperature resistant and chemical attack.
Utility model content
The purpose of this utility model is the deficiency for existing high intensity Nomex, there is provided a kind of intensity is high, and good toughness is resistance to
The Nomex of resistance to injection of injection, high temperature resistant and chemical attack.
The utility model provides following technical scheme：
A kind of Nomex of resistance to injection, including base cloth layer, the both sides of the base cloth layer are respectively equipped with the first enhancement layer and second
Enhancement layer, the outside of first enhancement layer are provided with elastic layer, are equipped with the outside of the elastic layer and second enhancement layer
Filter layer, the elastic layer are the web layer formed of mutually being tangled by polyurethane elastomeric fiber and polyolefin elastic fiber.
Preferably, the base cloth layer is the grid cloth formed that mutually tangled by polyester fiber, and base cloth layer has support and added
The effect of strong other fibrous layers.
Preferably, first enhancement layer and second enhancement layer are alkali-free glass fibre layer or basalt fibre
Layer, alkali-free glass fibre and basalt fibre are respectively provided with that intensity is high, corrosion resistant excellent properties, and the presence of two layers of enhancement layer can
Improve the intensity of Nomex.
Preferably, the filter layer is polyphenylene sulfide fibre layer, and filtering accuracy is high, high temperature resistant and resistance to chemical corrosion
It is good.
Preferably, the thickness of the elastic layer is 0.8-1.2mm, and the elastic layer of the thickness range can have Nomex
Enough toughness.
Preferably, the thickness of first enhancement layer and the second enhancement layer is 0.5-0.9mm, the reinforcement of the thickness range
Layer can significantly improve the overall intensity of Nomex.
The beneficial effects of the utility model are：
(1) the utility model is provided with elastic layer, passes through the polyurethane elastomeric fiber and polyolefin elastic fiber into the net of tangling
The overall elasticity of Nomex is improved, so that Nomex has very strong toughness, when preventing that Nomex is blown by big wind-force
Deformation and bending are damaged.
(2) the utility model is provided with the first enhancement layer and the second enhancement layer, it is possible to increase the overall intensity of Nomex, improves
Resistance to jetting performance.
(3) the utility model is using polyphenylene sulfide fibre layer as filter layer, and filtering accuracy is high, and high temperature resistant and chemically-resistant are rotten
Corrosion can be good.
