PP micro filter cloth for food, flour, sugar, fertilizer, electroplating

In addition to some advantages of ordinary needle-punched filter felt, polypropylene fiber has better acid resistance, alkalinity and lower softening point than polyester fiber. Therefore, polypropylene needle-punched filter felt is generally used in the field of liquid-solid separation where the smoke temperature is below 100 C and the acidity and alkalinity are higher or where the acidity and alkalinity are higher.

Product advantages:

In the field of liquid-solid separation, polypropylene needle-punched filter mat is usually used in conjunction with plate and frame press, vacuum suction filter, belt filter, centrifugal filter and other liquid-solid separation equipment. It not only has the characteristics of good dimensional stability, high strength and small elongation, but also has the unique advantages of low vacuum resistance, energy saving and easy cleaning because of its smooth surface, porous and high permeability. In the fields of mineral processing, coal preparation, petroleum and chemical industry, where fine particles need to be filtered and fine filtration guaranteed, the performance of PP needle-punched filter felt is far superior to that of traditional woven filter material.

Scope of application:

Polypropylene needle-punched filter mat is usually made of 3-D or 6-D polypropylene staple fibers and reinforced baseboard woven with high-strength silk. It is processed by needle-punching, calendering and heat setting.

Applications:

Polypropylene needle-punched filter felt is mainly used in liquid-solid separation of metallurgy, mining, petroleum, chemical industry, chemical fibre, medicine, food and other industries.
