Abstract
The utility model relates to a composite alkali-free fiberglass needled mat. Composite fiber layers are symmetrically adhered to the upper and lower surfaces of base cloth by using a needling machine, wherein the base cloth is a fabric which is woven from bulked alkali-free fiberglass yarns by a plain weaving method; the composite fiber layers are formed by mixing alkali-free fiberglass/basalt fibers/PTFE (polytetrafluoroethylene) fibers. The composite alkali-free fiberglass needled mat has the advantages of corrosion resistance, high temperature resistance, dew formation resistance, high filtering accuracy, strong breaking strength, long service life and the like, and is mainly applied to the field of flue gas dust removal in the industries of steel, cement, carbon black, chemistry, power generation, industrial furnaces and the like.
Description
Technical field
The utility model relates to a kind of filter felt, particularly a kind of alkali-free glass fiber compound spiked felt.
Background technology
At present, the flue-gas temperature of the industries such as iron and steel, cement, carbon black, chemical industry, generating, Industrial Stoves is higher, containing the material composition complexity such as acid, alkaline, common Nomex be difficult to meet its high-temperature particle thing to the calcination of filter bag and corrosive gas the destruction to filtrate; And due to dewfall phenomenon, make the dust of trapping in filter material surface fouling, and be difficult for peeling off and cause stopping up, and can make cleaner running resistance increase, directly affected the normal operation of cleaner.
Summary of the invention
Technical problem of the present utility model, is to provide a kind of high temperature resistant, corrosion-resistant, the alkali-free glass fiber compound spiked felt of Anti-dew.
For solving above technical problem, the utility model provides a kind of alkali-free glass fiber compound spiked felt, it is characterized in that: in the upper and lower surface of base cloth, adopt the symmetrical composite fibre layer of pasting of needing machine.
Described base cloth, the fabric that it adopts plain weave weave to be made into for a kind of varicosity alkali-free glass fiber yarn.
Described composite fibre, it is that alkali-free glass fiber/basalt fibre/PTFE fiber mixes.
Superior effect of the present utility model is as follows:
1, high temperature resistant, normal working temperature is 260 ℃, moment 300 ℃ of heatproofs.
2, glass and basalt fibre are all inorfil, and chemical stability is fabulous, acidproof, alkali resistance is strong, anticorrosive.
3, through multiple high temp, roll, smooth surface is smooth, Anti-dew, and dust is easily peeled off.
4, fracture strength is high, and wearability is good.
5, filtering accuracy is high, to the following dust-filtering efficiency of 1um, can reach 99.995%.
6, be out of shape littlely, shrinkage factor < 3%, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure explanation, 1-base cloth, 2-composite fibre layer.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in structural representation as of the present utility model in accompanying drawing, the utility model provides a kind of alkali-free glass fiber compound spiked felt, it is the upper and lower surface at base cloth 1, adopt the symmetrical composite fibre layer 2 of pasting of needing machine, described base cloth 1 is the fabric that a kind of varicosity alkali-free glass fiber yarn adopts plain weave weave to be made into, and described composite fibre layer 2 is by the mixing of alkali-free glass fiber/basalt fibre/PTFE fiber; Post processing mode has: PTFE dipping, high temperature hot pressing and the processing of singing.
The symmetrical fibrolaminar Nomex of alkali-free glass fiber/basalt fibre/PTFE fiber composite of pasting in alkali-free glass fiber base cloth two sides is called alkali-free glass fiber compound spiked felt.
The utility model is dropped into actual operating mode to be used, through implementing proof, continuous serviceability temperature of the present utility model is 260 ℃, moment serviceability temperature be 300 ℃, warp-wise fracture strength >=1850N/520cm, broadwise fracture strength >=1900N/520cm, warp-wise elongation at break≤10%, broadwise elongation at break≤10%, rupture strength >=3.8MPa, thickness 1.4-1.8mm, Air permenbility 320-500L/ ㎡ min.
