Plate frame filter press filter cloth is used for solid liquid separation, so it has higher requirements on resistance performance to both acid and alkali, and some time might on the temperature etc.
Polyester/PET Filter Press Cloth
Polyester Filter Cloth can be divided into PET staple fabrics, PET long thread fabrics and PET monofilament. These products possess the properties of strong acid- resistance, fair alkali- resistance and operating temperature is 130 centigrade degrees. They can be widely used in pharmaceuticals, non-ferry melting, chemical industrial for the equipment of frame filter presses, centrifuge filters, vacuum filters etc. The filtering precision can reach less than 5microns.
Polypropylene/PP filter Press Cloth
Polypropylene filter cloth possesses the properties of acid-resistance.Alkali-resistance, small specific gravity, a melting point of 142-140centigrade degrees, and operating temperature maximum of 90 centigrade degrees. They are mainly used in precision chemicals, dye chemical, sugar, pharmaceutical, alumina industry for the equipment of frame filter presses, belt filters, blend belt filters, disc filters, drum filters ect. The filter precision can reach less than 1 micron.
