Our company uses high-quality polypropylene fibers produced by Liaoyang Chemical Fiber Company to manufacture polypropylene needle-punched filter felt. In addition to some advantages of ordinary needle-punched filter felt, polypropylene fiber has better acid and alkali resistance and lower softening point than polyester fiber. Therefore, polypropylene needle-punched felt is generally used in areas with flue gas temperatures below ℃ and acid and alkali conditions. Situations with high acidity or liquid-solid separation fields 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. Not only does it have the characteristics of good dimensional stability, high strength, and small elongation, but also has unique advantages such as low vacuum resistance, energy saving, and easy cleaning because of its smooth, porous surface and high air permeability. In industries such as mineral processing, coal preparation, petroleum, and chemicals, where it is necessary to filter tiny particles and ensure fine filtration, polypropylene needle-punched filter felt has far superior performance than traditional woven filter media.
Polypropylene needle-punched filter felt is generally made of 3 or polypropylene short fiber, and is woven with high-strength silk to reinforce 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, related technical parameters, medicine, food and other industries.
