acrylic needle punched felt dust bag

1、 Related points of acrylic needle punched felt dust bag:

Acrylic needle punched felt is made by needle punching a mixture of fiberglass base fabric and chemical fibers. The product has good performance and tensile strength, with a normal operating temperature of 150 ℃ and a short-term temperature of 180 ℃. Suitable for the smoke and dust filtration industry with suitable temperature, high smoke and dust concentration, and high filtration requirements.

2、 Introduction to Acrylic Needle Felt Dust Removal Bag:

This acrylic needle punched felt, chemical name is polyacrylonitrile, is used as raw material to make felt by needle punching method, and then processed to make acrylic medium temperature hydrolysis resistant needle punched filter felt. The air permeability is 14m3/m2 • min, the instantaneous working temperature is 160 ℃, and the normal working temperature is 140 ℃. Needle punched felt is reinforced vertically and horizontally with acrylic woven fabric as the base fabric. It has excellent chemical resistance and hydrolysis resistance, and is used for dust collection of flue gas in spray dryers, coal mills, garbage incineration, asphalt, power plants, etc. It has the following properties: a. Relative humidity less than 30%, pay attention to oxidation; b、 Good acid and alkali resistance, with a pH value between 3-11; c、 The continuous working temperature is 130 degrees, and the instantaneous temperature does not exceed 140 degrees. Acrylic needle punched felt is mainly suitable for the smoke and dust filtration industry with suitable temperature, high smoke concentration, and high filtration requirements.
