P84 filter bags(felt fabric) finish treatment.
A plain P84 felt filter fabric(felt fabric) is unfinished. Some time need do finish treatement to withstand various conditions, just like moisture or abrasion. There are mechanical surface treatments and chemical treatments of either the P84 felt filter fabric(filter cloth) or just the felt fabric surface.
P84 felt filter fabric(filter cloth) mechanical surface treatments generally improve the dust cake formation on the filter fabric(filter cloth) and filter cleaning. Singed, eggshell, glazed, calendar and PTFE membrane is the common treatments. The first three smooth the surface of the needled felt to improve dust cake formation and filter cleaning.
Singed treatement running the fabric over an open flame to remove high points and fiber fuzz.
Eggshell treatement use the pressure is applied to produce a smoother, eggshell-like surface.
Glazed treatement like eggshell treatment, but which need more pressure is applied to produce a high-sheen surface.
Surface coated treatment can make proprietary smooth, non-fibrous, micropermeable coating with excellent dust cake release and improved resistance to blinding.
PTFE Membrane Laminating an expanded layer of polytetraflouroethylene (PTFE) to needled felt(filter cloth), after this process that makes it easier to clean sticky or very fine dust from the fabric and reduces the required cleaning frequency.
