8030 mm Heat Setting PTFE Filter Bag For Metal Recycling Smelting Furnace
To use PTFE as fabric and cover high-temperature fibers on top surface, after the final treatment, we can get the filtration materials suitable for the application of dust collection at the outlet of cement kiln. The materials can work and keep good performance under the condition of high dust contain, big temperature variation, unstable humidity and strong chemical corrosion. Our non-woven needled felt filtration material made with PTFE fabric has been widely applied in the fields of waste incineration, coal-fired boilers, blast furnace gas, cement turning kiln, ferroalloy, asphalt-stirring etc.
PTFE Filter Bag Advantage:
1. Excellent temperature resistance: up to 260℃ (572℉)
2. Extremely long working life. Service life can reach 6 years at the temperature 66℃～240℃ and normal working conditions.
3. Excellent performance of anti-acid and anti-alkali resistance
4. Excellent filter efficiency
5. Good performances of hydrolysis stability and flame retardant
6. Suitable using on various power plant boiler and waste incineration boiler. The weakness is poor folding property and higher price.
