non ferrous metal tin smelting filter bags
#P84 Polyimide filter bags
It has excellent fine powder collection efficiency and small operating pressure difference. In asphalt plants, cement plants, waste incinerators, liquid bed boilers, coal-fired boilers, etc, they have long-term experience in using P84 filter materials.
Product Features:
Advantages: good temperature resistance and trilobal cross section make the filter material made with good air permeability; oxidation resistance is better than PPS fiber.
Disadvantages: general hydrolysis resistance, moisture content is 5% at 170ºC working temperature, the higher the temperature, the less moisture content.
Applications:
1. Dust removal from the tail of the new dry cement kiln
2. Bag dust removal for some coal-fired power plants
3. Bag dust removal for some waste-to-energy generation
