Polypropylene filter cloth is made of polypropylene as raw material, and the fibre structure is formed through the melt spinning process, which is both acid and alkali corrosion resistant, anti-hygroscopic and high temperature resistant, and can be operated stably at 90℃, and some of the high-temperature-resistant models can withstand the environment of more than 200℃. Advanced imported equipments are used to ensure the balance of yarn tension, and optimise the surface smoothness of polypropylene filter cloth through high temperature shaping and calendaring technology. Qingdao Star Machine innovatively develops double-layer composite weaving polypropylene filter cloth, and the filtration surface adopts twill weaving, which enhances the efficiency of discharging the filter cake, and reduces the frequency of stopping to clean effectively.
Double-layer monofilament polypropylene filter cloth is widely used in solid-liquid separation process in pharmaceutical, chemical, precious metal, sludge, tailings treatment and other industries, such as vacuum horizontal belt filter, centrifuge and other equipment
Chemical smelting: resistant to strong acid and alkali environment, suitable for precious metal extraction, catalyst recovery and other high-precision separation scenarios.
Environmental protection treatment: high sludge dewatering rate, improve the efficiency of tailings dry discharge treatment.
