The needle felt uses a non-woven acupuncture method. The needles were needled into felts with staggered fibers in the space, and were made by a series of processes such as heat setting and calendering to form a three-dimensional space structure, which was smooth and smooth. Needle felt features: high porosity, good air permeability, reducing pressure loss and energy consumption; high purification efficiency; long service life; wear resistance, corrosion resistance, chemical stability.
Needle felt product features:
1. “Surface filtration” greatly reduces the phenomenon of paste bags;
2. Film-covered needle felt has excellent filtration efficiency (up to 99.99%);
3. Film-covered needle felt has excellent dust cake peeling performance;
4. Film-covered needle felts have low running resistance, high filtration speed, and large ventilation (30% more than normal filter materials), saving energy consumption
5. The film-covered needle felt has high filtration accuracy and can trap ultrafine dust with a particle size of 1 μm or less.
