P84 High Temperature Resistant Needle-punched Felt Bag

Short Description:

Polyimide fiber, also known as P84 fiber, is a heat-resistant fiber with excellent high temperature resistance. At 300℃ for 100 h, the strength retention rate is 50%, the elongation is reduced by 5% ~ 10%, and the exposure rate is 250 H, strength retention rate of 45%, excellent dimensional stability at 275℃, no melting, glass temperature of 315℃, only release a little harmful gas when decomposition. It can run continuously at 260℃ and the instantaneous working temperature can reach 280℃.

P84 fibers are known for their fineness. The fiber structure characteristics determine that the fiber surface area increases, the pores are small, the dust only stays on the surface of the filter felt but can not penetrate into the filter felt, the backwashing pressure is small, the operating resistance is low, and the elastic removal efficiency of the filter cake can be significantly improved. P84 fiber has strong dust resistance and dust capture ability, and can capture fine dust, so as to improve the filtration efficiency. Due to the irregular cross section of P84 fiber, the fiber has strong binding force and tangling force. Compared with glass fiber, the chemical properties, strength, wear resistance, fracture resistance and service life of P84 fiber are significantly improved. But the P84 fiber is not resistant to hydrolysis.

It has remarkable temperature resistance and good chemical resistance It has certain advantages in filtration of acid waste gas and alkaline dust It has low backwash pressure and high sludge cake efficiency It is used in asphalt plants. cement plants, waste incinerators. liquid bed boilers and coal-fired boilers.
