Product Description
P84_Bag is our company's selection of INSPEC FIBERS polyimide fiber produced by Austrian LENZING company. It is a new product produced under the guidance of the foreign company. It is a domestic production company of this filter material. The P84 characteristic is remarkable due to the fineness of the fiber itself, and the irregular fiber cross-section increases the fiber surface area to _ and provides a lot of tiny pores to make the surface filtration effect better than depth filtration. The dust only stays on the surface of the filter felt and cannot penetrate into the filter felt. Therefore, the backwash pressure is small and the filter cake bounce efficiency is significant, and the fine powder collection efficiency is small and the operating pressure difference is small. Suitable for coal-fired boilers, liquid-bed boilers, garbage incineration, asphalt plants, cement plants, waste incinerators, etc.
The filter material has the following three significant characteristics:
1. Significant temperature resistance Long-term use temperature of 260 ℃, with a safe space to deal with downtime and unexpected events.
2. Good chemical resistance The P84 filter bag has proved the filtering value of acid waste gas and alkaline dust in the waste incineration operation in the past ten years.
3. Low backwash pressure and high resilience cake efficiency The P84 characteristic is remarkable due to the fineness of the fiber itself, and the irregular fiber cross section increases the fiber surface area to _ and provides a lot of tiny pores to make the surface filtration effect better than depth In filtration, the dust only stays on the surface of the needle-punched filter felt and does not penetrate into the filter felt. Therefore, the backwash pressure is small and the filter cake bounce efficiency is significant. The fine powder collection efficiency is small and the operating pressure difference is small.
P84 is widely used in industries such as waste incineration power plants, cement plants, steel plants, and coal-fired boilers.
