Detail Information
Polyimide fiber, also named P84 fiber, is a remarkable ultrafine fiber with irregular fiber cross section which can greatly increase the filtration surface area of the fiber felt and provides a lot of minute pores to make a better surface filtration performance than the inner filtration of the filter felt. Dust only stays on the surface of the filter felt and cannot penetrate into the filter felt. Therefore, the reverse cleaning pressure is light and the filtration efficiency of dust cake can be remarkably improved, and the fine dust collecting efficiency is excellent and the working pressure difference is small.
FEATURES & BENEFITS
• Significant High-Temperature Resistance, Max Operating Temperature Is 260℃
• Good Chemical Resistance, Great Performance in Waste Incineration Operations
• Low Dust Cleaning Pressure and High Filtration Efficiency
APPLICATIONS
Asphalt Plant, Cement Plant, Waste Incinerator, Liquid bed Boiler, Coal-Fired Boiler, etc.
