polypropylene PP needle felt acid-resistant alkaline water filter needle felt/cloth

Polypropylene needle-punched filter felt made of high-quality polypropylene fiber, in addition to some advantages of ordinary needle-punched filter felt, polypropylene has better acid resistance, alkali resistance and better softening point than polyester fiber, and polypropylene The solubility stability is excellent, so the polypropylene needle felt is generally in the field of liquid temperature and temperature below 100 ° C and high pH, or the liquid-solid separation field of acid-base penetration, with plate and frame rolling filter, vacuum suction filter, bag filter, centrifugal Liquid filter equipment such as filters are used together.
