Product Description
P84 needle felt is remarkable for its fiber fineness, and the irregular fiber cross section increases the fiber surface area and provides many tiny pores, making the surface filtration effect better than the depth filtration. The dust only stays on the surface of the filter felt and cannot penetrate into the filter felt, so the filter cake ejection efficiency is significantly improved.
Advantages of P84 Needle Felt Filter Cloth
- High Temperature Stability: P84 has excellent high temperature stability and is able to maintain its physical and chemical properties under high temperature conditions. This makes P84 filter felt ideally suited for high-temperature gas filtration applications such as cement flue gas cleaning, the metallurgical industry and coal-fired power plants.
- Excellent Chemical Resistance: P84 has good resistance to chemical attack and can therefore be used in a variety of chemical conditions, including acidic and alkaline environments.
- Good Filtration Efficiency: P84 filter felts are generally effective at capturing tiny particles and dust, providing excellent filtration performance. This helps improve the capture and separation of particulate matter in the air or gas.
- Long Life and Wear Resistance: P84 generally have excellent wear resistance, which allows them to maintain a long service life under conditions of high flow rates and high particle loads.
- Low Shrinkage: The low shrinkage of P84 means it maintains its dimensional and shape stability even under high temperature conditions, ensuring continued filtration performance.
- Low Maintenance Cost: Due to the long life and high performance of P84 filter felt, its maintenance cost is relatively low as less replacement and repair work needs to be performed.
- Environmentally Friendly: P84 is a synthetic fiber that generally does not contain environmentally harmful substances, so it can be used in environmentally friendly applications.
