Abstract
The utility model relates to aN FMS high temperature resistant needled felt, wherein composite fiber layers are symmetrically adhered on the upper and lower surfaces of base cloth through a needle machine, the base cloth is alkali-free glass fiber yarn woven fabric, and the composite fiber layer is composed of mixed glass fiber/PTFE/P84/PPS; and the FMS high temperature resistant needled felt provided by the utility model has the advantages of corrosion resistance, high temperature resistance, folding resistance, high filtration precision, high filtration speed, long service life, etc.
Description
Technical field
The utility model relates to a kind of Nomex, particularly the high temperature resistant Nomex of a kind of Fu Meisi.
Background technology
At present, the flue-gas temperature of the industries such as cement plant, steel plant, power plant, chemical plant 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.Existing dust removal by filtration material used has: glass-fiber-fabric, woven dacron etc. several, but a lot of products all can not meet the needs of production, or are difficult to adapt to 220 ℃ of above worst hot cases, can use above at 220 ℃, but wearability and corrosion resistance do not reach again requirement.
Therefore, need a kind of novel high temperature resistant, wearability good, the composite filtering material of good corrosion resistance.
Summary of the invention
Technical problem of the present utility model, is to provide a kind of high temperature resistant, corrosion-resistant, the high temperature resistant Nomex of Fu Meisi that wearability is good.
For solving above technical problem, the utility model provides the high temperature resistant Nomex of a kind of Fu Meisi, 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, it is spinned cotton and woven cloth for alkali-free glass fiber.
Described composite fibre layer, it mixes for glass fibre/PTFE/P84/PPS fiber.
Superior effect of the present utility model is as follows:
1, high temperature resistant, long-term serviceability temperature reaches 240 ℃, moment 320 ℃ of heatproofs.
2, acidproof, alkali resistance is strong, anticorrosive.
3, the utility model is number of chemical fiber and glass fibre to be carried out organically compound, has overcome the not shortcoming of fold resistant of chemical fibre non-refractory, glass fibre.
4, fracture strength is high, and wearability is good.
5, gas filtration resistance is little, and efficiency of dust collection surpasses woven filtrate, and the rate of filtration is higher than one times of left and right of woven filtrate, and physical life is long.
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 the high temperature resistant Nomex of a kind of Fu Meisi, it is the upper and lower surface at base cloth 1, adopt the symmetrical composite fibre layer 2 of pasting of needing machine, it spins cotton and weave cloth described base cloth 1 for alkali-free glass fiber, and it mixes described composite fibre layer 2 for glass fibre/PTFE/P84/PPS fiber; Post processing mode has: PTFE dipping, high temperature hot pressing, singe and teflon is processed.
The Nomex of the symmetrical sticking glass fiber/PTFE/P84/PPS of glass fibre base cloth composite fibre layer is called the high temperature resistant Nomex of Fu Meisi.
The utility model is dropped into actual operating mode to be used, through implementing proof, continuous serviceability temperature of the present utility model is 240 ℃, moment serviceability temperature be 320 ℃, warp-wise fracture strength >=1800N/520cm, broadwise fracture strength >=1800N/520cm, warp-wise elongation at break≤10%, broadwise elongation at break≤10%, rupture strength >=3.8MPa, thickness 1.8-2.2mm, Air permenbility 350-600L/ ㎡ min, dust removal efficiency reaches 99.99%.
