P84 Non Woven Fabric For Dust Filtration At The Kiln Head And Kiln Tail In Cement Production
Farrtex® P84 needle felt filter material is a premium solution designed for demanding industrial filtration applications. Combining advanced P84 fibers with PTFE scrim, this high-performance filter bag excels in extreme environments, offering superior durability, thermal stability, and chemical resistance. Below, we detail its key features, advantages, technical parameters, and answers to common questions.
Key Features of P84 Filter Material
- Premium Material Composition
- P84 Fiber: A high-temperature polyimide fiber known for exceptional heat resistance (up to 260°C continuous) and resistance to chemical corrosion.
- PTFE Scrim: A polytetrafluoroethylene base fabric that enhances dimensional stability, reduces shrinkage, and improves mechanical strength.
- Optimized Physical Properties
- Weight: 550±5% g/m² ensures robust filtration efficiency without compromising airflow.
- Thickness: 2.4±0.2 mm provides a balance between particle retention and permeability.
- Air Permeability: 180-240 L/dm²/min (at 200Pa) allows efficient gas flow while capturing fine particulates.
- Advanced Mechanical Processing
- Heat Setting & Calendering: Ensures uniform fiber alignment and surface smoothness.
- PTFE Dipping: Adds a protective layer to enhance abrasion resistance and prolong service life.
- Exceptional Mechanical Performance
- Peak Load Resistance: MD >900 N/5cm; XD >1200 N/5cm (ideal for high-pressure systems).
- Low Strain & Shrinkage: MD strain <35%, XD strain <50%; linear shrinkage <15% (MD) and <10% (XD).
- Temperature Resistance
- Continuous Use: ≤260°C (e.g., coal-fired boilers, cement plants).
- Instantaneous Tolerance: ≤280°C (short-term exposure during peak operations).
Why Choose Farrtex® P84 Filter Material?
- Longer Lifespan: PTFE scrim minimizes shrinkage and deformation, reducing replacement frequency.
- Energy Efficiency: Optimal air permeability lowers pressure drop, saving operational costs.
- Chemical Resilience: Resists acids, alkalis, and solvents, making it suitable for harsh industrial emissions.
- Regulatory Compliance: Meets stringent environmental standards for particulate emission control.
