Dust Needle felt filter cloth , customized, carefully selected
Meet your needs to control dust emissions and extend service life
Aokai Envirotec low emission, low energy consumption, flue gas dedusting system expert. The whole set of Neele punched felt (polyester, acrylic, PPS, Teijin aramid, DuPont aramid, China aramid, P84, PTEE, glass fiber) are customized and carefully selected according to your dust collector type, dust concentration, dust composition and dust characteristic, so as to meet your needs to control dust emissions and extend service life.
Dust Needle felt filter cloth types
Fibre types | Weight (g/㎡) | Continuous temperature | Peak Temperature |
Polyester(PET) | 450-600 | 130℃ | 150℃ |
Acrylic(PAC) | 500-600 | 125℃ | 150℃ |
PPS | 500-650 | 160℃ | 190℃ |
Aramid | 400-600 | 204℃ | 240℃ |
PTFE | 750-800 | 240℃ | 260℃ |
P84/PTFE | 500-550 | 240℃ | 260℃ |
Fiberglass | 900-950 | 240℃ | 260℃ |
Careful production, perfect quality, stable performance
The weight deviation of all our products is ±2% that improvement the use of products in process of uneven air permeability and reduce the service life. Neele punched felt production uses double lapping and carding approach that finishes the final product in one single pass. All fiber will enter the feeding equipment, going through processes of scattering, mixing, carding, lapping and re-scattering. Punching will make the layers of fiber and scrim to inter-penetrate, forming semi-finished filter felt. High temperature treatment will then stabilize the shape and size of the felt.
Neele punched felt surface treatment technology
Solve the troubles of Neele punched felt selection caused by different dust characteristic in working conditions
In Aokai Envirotec, the felt may be further processed by pressing, coating, dipping, membrane-laying, or waterproof treatment according to particular requirements of customers.
Surface treatments and protective finishes have the following advantages:
1.Optimal surface filtration;
2.Lower energy costs by efficient cleaning of theNeele punched felt ;
3.Improved protection against mechanical and chemical influences;
4.Greater efficiency due to longer operational life;
The typical dust properties are of decisive importance for recommending the appropriate surface of the Dust Needle felt filter cloth .
