Overview
The P84 fiber of the dust bag needle punched felt is imported by our company from INSPEC in Austria. Due to its unique three leaf cross-sectional structure, several domestic manufacturers can produce P84 needle punched felt. P84_ needle punched felt has the following characteristics: P84 filter bag has the advantage of filtering acidic waste gas and alkaline dust. Trial application in asphalt halving stations, cement plants, and other working conditions

Needle felt
Has the following characteristics:
P84Filter bags have advantages in filtering acidic waste gas and alkaline dust. Applied to the trial of asphalt halving stations, cement plants and other working conditions.
Characteristics of P84 needle punched felt:
1. Significant temperature resistance
The operating temperature is 260 ℃, but there is a safe space to cope with downtime and unexpected events.
2. Good chemical resistance
The filtration value of P84 filter bags for acidic waste gas and alkaline dust has been confirmed in the past decade of garbage incineration operations.
3. Low backwash pressure and high efficiency of elastic sludge cake removal
The P84 characteristic is significant due to the fineness of the fiber itself, and the irregular cross-section of the fiber increases the surface area, providing many small pores to make the surface filtration effect better than deep filtration. Dust only stays on the surface of the filter felt and cannot penetrate into it, so the backwash pressure is low and the efficiency of filter cake bounce off is significant. It has good collection efficiency of fine particles and small operating pressure difference.
P84Fiber is widely used in smelting, chemical industry, waste incineration, cement kiln tail and other working conditions, with a service life of more than 3 years. It is an excellent performance filter material.
