P84 Dust Collector Filter Bag for Asphalt Mixing Plant

P84 Dust Collector Filter Bag for Asphalt Mixing Plant

Qingdao Star Machine’s top quality P84 filter bag can be used in different fields.The material of filter bag varies due to different application scenarios and filtration requirements.

P84 high temperature dust bag fiber, also known as polyimide, its basic chemical composition is mainly composed of aromatic units. 

P84 PARAMETER

PRODUCT FEATURE

P84 high temperature dust bag fiber filter material has the following characteristics:

1.P84 high temperature needle felt dust bag fiber cross section is irregular three-lobe shaped section, this special section makes P84 high temperature dust bag fiber surface area increases, high temperature P84 needle felt filter bag can effectively capture smile particles, easy to clean; 

2.P84 high temperature dust bag fiber is non-combustible; 

3.P84 high temperature dust bag fiber has very superior chemical properties, corrosion resistance; 

4.high temperature resistance P84 dust filter bag fiber high temperature resistance, can operate continuously at the temperature of 240 ° C, can withstand the maximum instantaneous temperature of 280 ° C.

P84 needle felt dust bag is a kind of flame-retardant, temperature stable fiber filter material, at 240℃ temperature conditions, the mechanical P84 polyimide fiber filter material will not change, the maximum temperature of up to 260℃. P84 fiber filter material has no melting point temperature and is a natural golden color. P84 polyimide fiber filter material is not hygroscopic fiber filter material (about 3% water absorption at 65% relative humidity).

In addition, because the P84 fiber is a special-shaped (leaf) section structure, with a large filtration surface area, and excellent filtration performance, the P84 fiber is often implanted in the surface of other dust bags (dust facing side to improve the filtration performance of the filter material). For example, the special Flumez filter bag for blast furnace gas dust collector is mixed with a considerable proportion of P84 fiber to improve the filtration effect and high temperature and corrosion resistance.

The characteristics of P84 dust bag are significant because of the fineness of the fiber itself, but also because the irregular fiber cross section increases the fiber surface area to the maximum and provides a lot of tiny pores to make the surface filtration effect better than the depth filtration. The dust only stays on the surface of the filter bag and does not penetrate into the filter felt, so the backwash pressure is small, the filter cake bounce efficiency is significantly improved, and the fine powder collection efficiency is excellent and the working pressure difference is small.

P84 needle felt dust bag is a high-end high temperature resistant filter bag that can be compared with PTFE needle felt filter bag, and even its filtration efficiency and ash cleaning effect are higher than PTFE needle felt filter bag.
