Supply Zhejiang medium temperature filter bag acrylic needle felt dust bag chemical resistance

Polypropylene needle-punched felt bag Our company uses high-quality polypropylene fiber to manufacture polypropylene needle-punched filter felt. In addition to some of the advantages of ordinary needle-punched filter felts, polypropylene needle-punched felts are generally used in areas where the flue gas temperature is below ℃ and in acid and alkali conditions because polypropylene fiber has better acid and alkali resistance and a lower softening point than polyester fiber. Places with high acidity or liquid-solid separation areas with large acidity and alkalinity.
In the field of liquid-solid separation, polypropylene needle-punched filter felt is usually used in conjunction with liquid-solid separation equipment such as plate and frame filter presses, vacuum suction filters, belt filters, and centrifugal filters. It not only has the characteristics of good dimensional stability, high strength, and small elongation, but also has the unique advantages of small vacuum resistance, energy saving, and easy cleaning because of its flat and smooth surface, porosity, and high air permeability. In industries such as mineral processing, coal preparation, petroleum, chemical industry, etc., where it is necessary to filter fine particles and ensure precise filtration, polypropylene needle-punched filter felt has far superior performance than traditional woven filter media.
Polypropylene needle-punched filter felt is generally made of polypropylene short fiber or polypropylene short fiber, and is woven with high-strength silk to strengthen the base fabric, and is made through acupuncture reinforcement and post-processing processes such as calendering and heat setting.
Polypropylene needle-punched filter felt is mainly used in the field of liquid-solid separation in metallurgy, mining, petroleum, chemical industry, chemical fiber, medicine, food and other industries.
