Description
Technical field
The utility model is related to a kind of folding, resistant to elevated temperatures, stable physical property, and basalt resistant to chemical etching is combined
Felt.
Background technology
In the filtrating smoke dust of the industry operating mode such as some metal smelts, construction material, chemical industry, such as steel plant, ferroalloy,
The filtering material that the operating modes such as carbon black are used is generally the acupuncture lacing felt filter material that various fibers are made.There is following ask during filtrate use
Topic：The complicated flue gas corrosion of smoke components that is discharged due to operating mode is big, oxygen content is high, water capacity is big, many more than fine dust etc.
Factor, causes to cause PO PE NT PTFE the phenomenons such as the decline of burn into strength, paste bag occur, causes filter bag damage, failure.Have a strong impact on
The normal work of duster system and the normal operation of production, as filter bag use time is long, the dust in filtrate can be along gas
Flowing pressure is on the increase, and flue gas and dust contain certain humidity, temperature or oil stain, because filter bag high-temperature resistant result is poor, main former
Because the contraction of felt is larger or deformation, and when exhaust gas dust or compressed air pass through composite felt, the powder with moisture and oil stain
Dirt and impurity can be such that the hole of composite felt progressively blocks, and filter bag easily " hardened " (being commonly called as " paste bag "), increases running resistance, very
To blocking, causing system to handle, air quantity declines, fan operation energy consumption increases, and the working life of filter bag is shortened, even if removing
Dirt device deashing is all right, can not check the resistance that operation persistently rises, and causes deduster exhaust not smooth, carries out gray back, make
Into secondary pollution；So it is resistant to elevated temperatures, stable physical property, basalt resistant to chemical etching, which is combined felt material, can more meet city
The demand of field.
Utility model content
The utility model purpose be in order to overcome the deficiencies in the prior art and a kind of folding is provided, it is resistant to elevated temperatures, it is physical
Energy stabilization, basalt composite felt resistant to chemical etching.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of glass basalt composite felt, including it is swollen
Body glass fibre base fabric, basalt composite fibre layer and polytetrafluoroethylene floor；The both sides of the bulk glass fiber base fabric are set
There is basalt composite fibre layer, be composited using needling technique；Set on the windward side of the basalt composite fibre layer
There is polytetrafluoroethylene floor.
It is preferred that, the bulk glass fiber base fabric is as raw material to knit plain cloth by 6 microns of spun yarns, while being weaved cotton cloth to spun yarn
During carry out expanded form.
It is preferred that, the polytetrafluoroethylene floor is used for thorn technology formation poly tetrafluoroethylene.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
A kind of glass basalt composite felt of the utility model scheme, bulk glass fiber folding resistance is good, the stabilization of size
Property it is good, be unlikely to deform, so PP high temperature stratiform compound spiked felts performance is stable, filtering accuracy is good, efficiency high, service life is long,
Production efficiency is improved, production cost is reduced.
