1.Polyimide  needle felt introduction

P84 Needle Felt with PTFE Membrance

1. P84 dust removal cloth bag has good chemical resistance. It has been proved that P84 filter bag has the filtering value for strong acid and strong alkaline acne in many years of waste incineration environment work; 

2. P84 dust removal filter bag is used as a kind of dust removal cloth bag. the temperature-resistant type can reach 260℃ in long-term working height, which is enough to cope with the occurrence of shutdowns and accidents; 

3. P84 dust-removing cloth bag has low backwash pressure and high elasticity of mud cake removal efficiency; 

4. P84 dust-removing cloth bag has better the collection efficiency of fine particles and the small operating pressure difference can reduce enterprise costs; 

5. P84 filter bag has excellent chemical stability; 

6. P84 filter bag has a wide range of applications, such as waste incineration, power plants, asphalt plants, cement kilns, and boilers Industries, waste incinerators, drying, smelting and other industries are well applied in various industrial enterprises such as flue gas purification.
Compared with glass fiber cloth bags, P84 high temperature dust removal cloth bags have a filtering speed of more than 1, 0m/min and low running resistance. Compared with synthetic chemical fiber filter media, the dimensional stability and strength of the product are significantly improved in terms of performance, flexural resistance and peeling strength. P84 high-temperature dust-removing cloth bags can bear high filtration loads. Overcoming the weaknesses of chemical fiber filter materials such as large elongation, large deformation, low temperature resistance, and poor corrosion resistance, P84 high temperature dust removal cloth bag and the price is lower than other chemical fibers.

5.Application Area:

P84 dust bag is commonly used in steel plant Fomex dust bag, p84 dust bag, pps dust bag, polypropylene needle felt dust bag easy to clean the dust filter bag of polyester needle felt dust collector is the central part of the dust collector, and the size of the filter bag Design, filter cloth cutting and processing and manufacturing of high-temperature dust-removing cloth bags all have strict requirements. these requirements are of major significance to the normal operation and convenient maintenance of the bag filter, and to extend the service life of the filter bag.
P84 fiber has excellent resistance to high performance, can run continuously at 260℃, and the instantaneous working temperature can reach 280℃. P84 fiber is very thin, the surface area of the fiber is large, the pores are small, and the dust can only stay on the surface of the filter felt. but cannot penetrate into the felt, the pressure required for dust removal is small, the running resistance is low, and the efficiency of filter cake removal is obvious: P84 fiber has strong dust resistance and capture ability, and can capture tiny dust, thereby improving the filtration efficiency: Due to the irregular cross section of P84 fiber, the fiber has strong cohesion and entanglement. Compared with glass fiber, the chemical properties, strength and service life of P84 fiber are significantly improved, but P84 fiber is not resistant to hydrolysis.
