PPS Needle Felt with PTFE Membrane

What is PPS

PPS is a kind of high-performance fibres, golden yellow in colour, good heat resistance, can be used for a long time at 190 degrees, excellent flame retardancy, excellent chemical resistance, second only to PTFE, and stable to a variety of organic solvents.

PPS Needle felt with PTFE membrane is suitable for chemical industry and other industries that require high temperature flame retardant.

Advantages of PPS Needle felt with PTFE membrane

PPS Needle felt with PTFE membrane can achieve surface filtration with nearly 100% retention of the filtered material.

(1) High surface filtration efficiency. Usually industrial filter media is deep filtration. It relies on the establishment of a dust layer on the surface of the filter media to achieve effective filtration. Establishment of effective filtration time is long (about 10% of the entire filtration process), high resistance, low efficiency. Incomplete retention, high loss, high filtration and blowback pressure, frequent dust removal, high energy consumption, short service life, large equipment footprint.

The use of PPS Needle felt with PTFE membrane, dust can not penetrate into the filter media, is the surface filtration, whether coarse, fine dust, all deposited on the surface of the filter media, that is, by the membrane itself, the aperture of the filtrate intercepted by the filtrate, no initial filtration period, the beginning of the effective filtration, nearly one hundred per cent of the time in the effective filtration.

(2) Low pressure, high flux continuous operation. Traditional filter media for deep filtration, once put into use, dust penetrates and establishes a dust layer once, and the permeability decreases rapidly. When filtering, the internal accumulation of dust causes blockage, thus increasing the resistance of the dust removal equipment.

PPS Needle felt with PTFE membrane with fine aperture and its non-stickiness, so that the dust penetration rate is close to zero, put into use to provide excellent filtration efficiency, when deposited on the surface of PTFE Membrane filtered material reaches a certain thickness, it will automatically fall off. Easy to clear the dust, so that the filtration pressure is always kept at a very low level, the air flow rate is always kept at a high level, and can work continuously.

(3) Easy to clear the dust. The operating pressure loss of any kind of filter media depends directly on the amount of dust remaining or staying on the surface of the filter media, PPS Needle felt with PTFE membrane can be cleaned in just a few seconds, has very superior characteristics of the ash, each time the ash can be completely removed from the dust layer. The filter media will not cause internal blockage, will not change the porosity and mass density, and can always maintain a low-pressure environment.

(4) Long life. PPS Needle felt with PTFE membrane can exert its superior characteristics regardless of the soot removal mechanism, and it is a kind of filter material that will dust collector designed to fully exert its high efficiency filtration, and thus low cost. Coated filter media is a strong and soft fibre structure, and strong substrate composite, so there is enough mechanical strength, coupled with excellent soot removal, reducing the intensity of soot cleaning, in the low and stable pressure loss, can be used for a long time, prolonging the life of the filter bag.
