Acrylic Needle Felt Bags are widely used in dust collection industries such as waste incineration, asphalt, spray dryers, coal mills, and power plants.
Acrylic needled felt dedusting cloth bag has the chemical name of polyacrylonitrile. It is made into needle felt by needle punching method, and then treated with special water-repellent treatment to obtain acrylic medium temperature anti-hydrolysis needle punched filter felt. Instant working temperature: 160 ℃,
Normal working at 140 ℃, the needle felt is made of acrylic woven fabric as the base cloth to enhance the vertical and horizontal strength. The product has excellent chemical resistance and hydrolysis resistance. Acrylic Needle Felt Bags are widely used in dust collection industries such as waste incineration, asphalt, spray dryers, coal mills, and power plants.
