P84 (PI-polyimide) is a filter material with the properties of flame resistance,
high temperature resistance.Polyimide will keep a good performance
when the temperatures up to 240 degree centigrade, instant can up to 260 degree
to 300 degree. Polyimide is leaf-shaped structure with a larger filter surface,
and always embedded in the surface of other needle felt with different material to
improve the filter efficiency. For the properties of high Temperature resistant filter material,
good chemical resistance, good air permeability, high filtration efficiency,
mostly applied in Cement kiln, Asphalt, Waster Incinerator, coal boilers, etc.
P84 dust collector filter bag for flour mill air filter use
The filter bag is a key part of the operation of the bag filter. Usually the cylindrical filter bag is suspended vertically in the dust
collector. The fabric and design of the filter bag should be as efficient as possible for efficient filtration, easy dust removal and
durability. In pulsed and air box type pulse dust collectors, dust is attached to the outer surface of the filter bag. When the dust-
laden gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, and the clean gas passes
through the filter material and enters the inside of the filter bag. The cage inside the filter bag is used to support the filter bag to
prevent the filter bag from collapsing, and it helps to remove and redistribute the dust cake.
Filter bag is the most important part in dust collector which influences the collection efficiency and working temperature.
Renewal of bags creates major cost in maintaining bag house, so the lifetime of bags are the main factor affecting the cost
and working condition of bag-house.
Industry Polyester antistatic yarn needle punched dust filter bag,can be widely used in mine,limestone,cement,iron and
steel industries,alumina delivery,electrolytic aluminium,non-ferrous metal production industries and so on.It is made
with anti-static fiber (line,cross,blended/mixed),water&oil repellent treatment,PTFE/Teflon mamebrane,PTFE dipping.Also
the after-treatment can be made into smooth surface,super smooth surface,rough surface,super rough surface,all based on
your design.
The filter bags are the key elements which determine the dust collecting effciency and working temperature.
