P84 filter bag


P84 filter bag is a kind of flame retardant, heat resistance and stable fiber filter material, under the condition of temperature 240 ℃, P84 polyimide fiber filter material mechanical didn't change, the highest heat resistance up to 260 ℃. P84 fiber filter material has no melting point temperature and is naturally golden yellow. P84 polyamide fiber filter material is not a hygroscopic fiber filter material (at 65% relative humidity, about 3% water absorption).

In addition, P84 fiber is often implanted in the surface layer of filter material (dust side to improve the filtration performance of filter material) because it is a special-shaped (leaf-shaped) cross-section structure with large filtration surface area and excellent filtration performance.

Technical parameters

1. Remarkable temperature resistance: working temperature 260 ℃, but has a safe space for the closing downand the unexpected events and so on.

2. Good chemical resistance: the value of P84 filter bag in filtering acid waste dust has been proved in the past decade of refuse incineration.

3. Low backwash pressure and high elastic desilting cake efficiency: the characteristics of P84 are remarkable because of the fineness of the fiber itself, and the irregular cross section of the fiber increases the surface area of the fiber to the maximum and provides many tiny pores to make the surface filtration effect better than the depth filtration. The dust only stays on the surface of the filter blanket but fails to penetrate into the filter blanket. Therefore, the reverse washing pressure is small, and the elastomodic efficiency of the filter cake is significantly improved, with excellent collection efficiency of fine particles and small operating pressure difference.

Airslide Fabric

Air slide fabrics are used for the pneumatic conveying of fine dry powdery products such as cement. The air slide cloth divides the air slide into upper and lower chambers. The chamber is inclined at as low as 1.5°.Compressed air is injected into the lower chamber which then goes through the media and “fluidises” the cement powder. The cement then behaves like a fluid and “flows” down the length of the chamber.


Airslide is a semi-permeable textile cloth which allows air to pass through but not the products.

Airslide Fabrics other names are: airslide fabric,air slide fabric,air permeable fabric,fluidising fabric,fluidizing fabric,air slide belt,air slide canvas,aeroslide,airslide membrane,aeration pad, aeration fabric.air slide fabric in shipping,air slide fabric for silos,chute bottoms.
