P84 High Temperature Resistant Dust Filter Bag

P84 high temperature resistant needle felt is made of polyimide fiber produced by Austrian LNGZING Company. It has high temperature resistance, acid and alkali resistance, and flame retardant properties. Under the condition of 240℃, the mechanical properties of P84 polyimide fiber filter material will not change, and the high temperature resistance can reach 260℃. P84 fiber filter material has no melting point and is naturally golden yellow. P84 polyimide fiber filter material is not a hygroscopic fiber filter material (about 3% water absorption under 65% relative humidity). In addition, since P84 fiber has a special (leaf-shaped) cross-sectional structure, it has a large filtering surface area and excellent filtering performance, so P84 fiber is often implanted in the surface of the filter material (dust-facing side to improve the filtering performance of the filter material). P84 is mainly used for flue gas purification in asphalt mixing, cement kilns, drying, combustion, smelting, various industrial kilns, coal-fired boilers and garbage incineration processes, and is widely used in processes with high emission concentration requirements.

★Product features and technical parameters:

★Product advantages:

The cross section of the P84 high temperature resistant needle felt dust bag fiber is an irregular trilobate cross section. This special cross section increases the surface area of ​​the P84 high temperature resistant dust bag fiber. The high temperature resistant P84 needle felt filter bag can effectively capture tiny particles and is easy to clean. The P84 high temperature resistant dust bag fiber is non-flammable. The P84 high temperature resistant dust bag fiber has very superior chemical properties and is corrosion-resistant and high temperature resistant. The P84 dust filter bag fiber is high temperature resistant and can operate continuously at a temperature of 240℃ and can withstand an instantaneous temperature of 280℃.

★Introduction to polyimide fiber:

Polyimide fiber (P84) has good high temperature resistance and can operate continuously at 260 degrees. The instantaneous temperature can reach 280 degrees. P84 fiber is very fine, with a large fiber surface area and tiny pores. Dust can only stay on the surface of the filter felt and cannot penetrate into the felt. The backwash pressure is small and the running resistance is low. It has strong dust blocking and dust catching capabilities and can capture tiny dust, thereby improving the filtration efficiency. Due to the irregular cross-section of P84, the fiber has a strong cohesive entanglement force. Compared with glass fiber, P84 has significantly improved chemical properties, strength, wear resistance, folding resistance, and service life. The disadvantage is that P84 is not resistant to hydrolysis.

Q. What is the service life of basalt dust filter bags?
A. The service life of basalt dust filter bags is generally 2-5 years, and the specific life depends on the following factors:
Temperature and chemical environment: High temperature and highly corrosive environment will accelerate the aging of filter bags.
Dust concentration and cleaning frequency: High dust concentration and long-term uncleaned dust may cause filter bags to be blocked or damaged.
Operation and maintenance: Regular cleaning and inspection can significantly extend the service life of filter bags.
