P84 cloth bag

P84 bag is a type of dust removal filter bag with stable performance, mainly used in the industrial flue gas purification industry.

Material and Structure: The main material of P84 bag is 90% P84 fiber, which is polyimide fiber. This fiber has a unique (leaf shaped) cross-sectional structure and a large filtering surface area, which can improve filtering performance. Cloth bags are usually made into needle punched felt using needle punching technology, which undergoes post-treatment such as heat setting and firing pressure to make their structure more stable.

Technical parameters: The P84 filter bag has a square weight of 550g/m ², a thickness of approximately 2.3mm, an air permeability of 170L/dm ²/min, a fracture strength of 800N/5cm longitudinally and 1000N/5cm transversely, a continuous working temperature of up to 240 ℃, and an instantaneous working temperature of 260 ℃.

Performance characteristics:

It has excellent thermal stability, with a continuous working temperature of up to 260 ℃ and short-term temperature resistance of up to 280 ℃. It can maintain the integrity of fiber morphology and mechanical properties under high temperature conditions.

Good filtration efficiency: The synergistic effect of irregular cross-section fibers and gradient pore structure can achieve effective interception of particles larger than 0.3 μ m, with a stable filtration efficiency of over 90%.

Good chemical stability: The imide groups in the P84 fiber molecular chain form a conjugated system, which gives it good resistance to hydrolysis and oxidation. It can also be used for a long time in environments where acidic gases and alkaline dust coexist.

Easy to clean: The surface filtration characteristics make it difficult for dust to penetrate into the interior of the filter material, resulting in good cleaning effect, low pressure drop loss, and continuous operation.

Application industry: P84 bags are mainly used for flue gas purification in processes such as asphalt mixing, cement kilns, drying, combustion, smelting, various industrial kilns, coal-fired boilers, and waste incineration, and are widely used in processes with high emission concentration requirements.

Dimensions: The P84 bag comes in various sizes, with common diameters of 120mm, 130mm, 160mm, and lengths of 2000mm, 3000mm, 6000mm, etc. It can be customized according to different dust removal equipment requirements.
