Description
According to the dust collection characteristics of blast furnace gas coal grinding dust and the cement plant coal grinding dust, and the needs of other industries, we use anti-static needle felt. It can be mixed with the anti-static fiber or the stainless steel conductive materials into the back web of fabric to make the anti-static needled felt has more excellent anti-static performance.
According to the different requirements of the different working condition, surface treatment can be done as singeing, calendaring, oil and water proof, PTFE impregnation, coating, PTFE lamination etc.
