High Temperature Insulation Polyimide Dust Collector Bags

Description

The surface of our P84( polyimide) dust collector bags is made of Austria imported P84( polyimide) fiber, the section is a regular three - leaf section, which is 89% more surface area than the general circular section.

The P84 dust collector bag has good high temperature resistance and can be used continuously below 240℃, Instantaneous heat up to 260℃, water absorption is 3%, With a certain degree of hydrolysis, Suitable for water vapor content less than 38% working conditions.

All properties of imported P84( polyimide) fibers are superior to those of domestic fibers.

The P84 fibers are flexible, P84 fiber can significantly improve the compound fastness and overall strength of the filter material.

Polyimide scrim can ensure that the filter material has sufficient mechanical strength. And the dust collector bags are with unique post-treatment PTFE mixed overall impregnation treatment, after high temperature sintering, wrap the fiber surface into a protective film, greatly improve the oxidation resistance, corrosion resistance, temperature resistance and dimensional stability of filter media.

P84( polyimide) needle felt dust collector bags features as follows:

(1) Good temperature resistance

The selection of P84( polyimide) fiber at 260℃ can fully ensure that the strength of the filter material is not lost at high temperature, and the operating temperature can be controlled between 260℃ and above the dew point under normal working conditions.

(2) Corrosion resistance

P84( polyimide) fiber has good corrosion resistance, and after the whole filter material is treated with corrosion resistance and PTFE( PTFE), the PTFE( PTFE) will form a dense protective film on the fiber surface, which improves the oxidation resistance and corrosion resistance of the filter material. Therefore, the filter bag is eroded very little during operation.

(3) Easy to clear ash, no blockage, stable operation

P84 dust collector bags are after PTFE( PTFE) impregnation, high temperature film, smooth surface, high dust stripping rate, easy to clean ash. A small number of dust entering the filter material, because of the narrow and wide channel formed by the filter material, the dust can pass through the filter material to reduce the accumulation, will not lead to the blockage of the filter material, keep the filter material running for a long time and slow down the inherent resistance of the filter material.

(4) Strong stability

P84( polyimide) needle felt filter bag is made of high performance P84( polyimide) scrim, strong and stable, processed by pretreatment process, physical and chemical indexes are improved significantly. The filter material is impregnated with PTFE( PTFE) and fixed at high temperature, and the shrinkage rate is very small at high temperature. Will not affect the gap between the filter bag and bag cage, to ensure ash removal effect.

(5) High filtration accuracy

After high temperature PTFE( PTFE) impregnation process, the surface layer improves the filtration accuracy of the filter material, which is beneficial to the rapid forming of the primary dust layer and the realization of high precision filtration. P84 dust collecotor bags is easy to clear ash and the dust stripping rate is high.

P84( polyimide) needle felt filter bag filtration accuracy is significantly improved than ordinary filter media. So the filter bag filter accuracy is high.
