 Heat-resistance Needle Felts

Description

P84 high temperature needle punched felts is made of polyimide fiber.

 

Features

The heat-resistance needle felts has the following three notable features:
1. High temperature resistance
Max. operating temperature: 240℃/464℉; Ultimate temperature: 260℃/500℉, so that a safe temperature space to cope with downtime and accidents:
2. Good chemical resistance
In the past ten years of incineration of waste incineration work has been confirmed P84 bag acid dust and alkaline dust filter value.
3.Low backwashing pressure, high shells slime removal efficiency
The P84 characteristic is remarkable due to the fineness of the fiber itself, but also because the irregular cross-section of the fiber increases the surface area of the fiber to the maximum and provides a lot of tiny pores to make the surface filtration effect better than the depth filtration.
 

Application

In the asphalt plants, cement plants, waste incinerators, liquid-bed boilers, coal-fired boilers, have long-term use of heat-resistance needle felts.
