SFFILTECH ordinary temperature acrylic needle cloth filter bag for waste incineration asphalt coal mill power plant
Product Description
Acrylic needle punched felt filter bag, chemically named acrylonitrile, is made from acrylic needle punched felt produced by needle punching method. Acrylonitrile fiber is produced using different production equipment and manufacturing processes according to the characteristics of working conditions and usage requirements. After special hydrophobic treatment, it is then singed, heat set, and rolled to produce acrylic needle felt with high filtration performance. Then, sew a traditional PPS filter bag with acrylic needle felt.
What is an acrylic filter bag?
Acrylic filter bags, meticulously engineered from durable synthetic fibers, represent a pinnacle in industrial filtration solutions. Crafted with precision, these bags, including polypropylene and other synthetic polymers, showcase remarkable chemical resistance and excel in high-temperature applications. Tailored for diverse industrial needs, our customized filter bags offer high-performance solutions for dust collection, air filtration, and various industrial processes. Whether it's the efficiency of man-made fiber or the reliability of polymer, our synthetic fiber filter bags stand out in providing longevity and sustainable solutions. Explore the versatility of high-performance acrylic filter bags, designed to contribute to cleaner air quality and environmentally responsible industrial practices.
Two factors effect the choice of filter bags
Dust Separation Procedure
Different dust separation procedures require different weights and air permeability values for filter media.
Rules:
- The more effective the cleaning process, the more compact and heavier the filter medium can be.
- The higher the emission control standards, the heavier the filter medium should be.
Tops: If these factors are well considered in advance, running cost like electricity for the fan or pressured-air for the cleaning pulses can be saved later on in a great amount.
