Acrylic needle felt

Acrylic, also known as polypropylene fiber, is used as a raw material to form a felt through needle punching. The high-temperature filter bag is then subjected to special water repellent treatment to obtain acrylic medium temperature anti hydrolysis needle punched filter felt. The product has a breathability of 14m/m2 · min, an instantaneous working temperature of 140 ℃, and the acrylic dust removal bag works normally at 125 ℃. The needle punched felt is made of acrylic woven fabric as the base fabric to enhance its longitudinal and transverse strength. The product has excellent chemical resistance and hydrolysis resistance, It is widely used in Incineration, asphalt, spray dryer, coal mill, power plant and other flue gas dust collection industries.

Acrylic needle punched felt is a fine fiber cloth made by using non-woven needle punched technology, which uses strong acrylic fibers arranged in a staggered manner and evenly distributed gaps. The surface is treated by hot rolling, singeing, etc. to make it smooth and not easily blocked by dust. This filter material has large gaps, good breathability, and strong chemical stability, which can not only filter room temperature gases, but also can filter room temperature gases, And filtering medium temperature gas (150 ℃) is also an ideal choice for filtering materials under acidic and alkaline corrosive gas conditions.
