一般的工業粉塵在濃度達到一定程度后（及爆炸極限）如遇靜電放火花或者外界點火等因素，則極易導致爆炸和火災。如：面粉塵，化工性粉塵，煤粉塵等如遇靜電、防靜電都有爆炸的可能。在袋式除塵領域，如這些粉塵需要用布袋來收集，則要求制作出具有防靜電性
Commonly explosion will be caused should the industrial dust meet static discharge or outside fire when dust explosive limit arrived. The possibility exist in such factory as flour, chemistry , coal and so on. Should factory choose bag filter to collect dust  the bag must be anti-static.

我公司根據國內高爐煤氣煤磨收塵和水泥廠煤磨收塵及其他行業的需要開發并生產了防靜電針刺過濾氈。
Our company develop and produce the anti-static needle felt according to market needed.

生產靜電濾布除了具有生產普通針刺氈的工藝外，還要求在生產針刺氈的化學纖維中混入導電纖維或不銹鋼導電材料，制成了抗靜電性能更加優異的抗靜電針刺氈。表面處理方式按照工況條件的不同要求，可進行燒毛，軋光，拒水防油，PTFE浸漬，涂層，覆膜等處理。
To produce anti-static filter cloth not only need to meet basic techniques but also need mix conductive fibers or stainless steel wire to dissipate static electricity. Finishing treatment could be made according to working condition such as singeing, calendering, water and oil proof, PTFE immersion, coating,  membrane.
