產品說明 Product description
PTFE 針刺氈是采用 PTFE(聚四氟乙烯纖維)經三維針刺而成的一種過濾材料。PTFE 纖維為大分子線性結構,因而具有極強的耐 溫、耐磨、耐化學穩定性,廣泛適用于鋼鐵、電力、垃圾焚燒等各種惡劣的煙氣過濾環境。
PTFE needle felt is a kind filter material which is made of PTFE (PTFE fiber) through three dimensional needling.PTFE fiber is a macromolecular linear structure,so it has a strong temperature resistance,wear resistance,corrosion resistance,chemical stability,widely used in iron and steel,electricity,garbage incineration and other harsh flue gas filter environment.
