Material of P84 filter bag
P84 Chemical
Name: Polyimide.
Fiber shape: Synthesized from
biphthalic anhydride and p-phenylenediamine, yellow, with a
trilobal fiber cross-section. Under the premise of the same
weight and linear density, such a structure greatly increases
the surface area of the fiber, which is more beneficial for
intercepting dust during the filtration
process.
P84
filter material: It is obtained from polyimide fiber by
needle punching, and its characteristics are remarkable
because of its own fiber fineness. The normal weight of P84
filter felt have 450gsm, 500gsm,
550gsm.
P84 filter felt treatment: Singed, calendered, heat set, water&oil repellent, blending conductive
The diameter of the P84 filter bag: diameter 100mm, 125mm, 130mm, 150mm, 180mm, 250mm etc. Any length is available. Special size is customize.
P84 filter
material has the following advantages:
1)
Significant temperature resistance: it can work at a
temperature of 260 °C for a long time, and the short-term
working temperature can reach 280 °C
2) Good acid and alkali resistance
and oxidation resistance, and certain hydrolysis
resistance.
3) Low pressure and high effect;
polyimide has an irregular fiber cross section, because P84
filter material has a large surface area, providing more tiny
pores, and its surface filtration effect is better than depth
filtration, so most of the dust is only It stays on the
surface of the filter felt and does not penetrate into the
deep layer, so the backwashing pressure is small, the filter
cake ejection efficiency is significantly improved, and the
fine powder collection effect is excellent, and the
filtration pressure difference is
small.
Because of its
high temperature resistance and hydrolysis resistance, P84
filter material is generally recommended to be used in flue
gas conditions with high dust concentration, high temperature
and low moisture content, such as asphalt mixing, cement
kiln, drying Flue gas purification in drying, combustion,
smelting, various industrial kilns, coal-fired boilers and
waste incineration processes, and is widely used in processes
with high emission concentration
requirements.
