"Polypropylene filter bag, or PP filter bag, is a bag-shaped filter element made of polypropylene, which is mainly used in petrochemical, paint and paint, biomedicine, automobile manufacturing, food and beverage, industrial dust removal and other fields. The filter material forms a three-dimensional , Highly fluffy three-dimensional depth, tortuous and tortuous filter layer, which is characterized by loose fiber structure, which increases the capacity of impurities at a high rate. This fiber material is a compound interception mode, which effectively removes solid and soft particles, namely Larger particles and impurities are trapped on the surface of the fiber, while fine particles are trapped in the deep layer of the filter material to ensure that it will not be damaged due to pressure increase during use, so it has a higher filtration efficiency. In addition, high-temperature surface heat treatment, namely application The instant sintering technology calendering treatment can effectively prevent the fibers from being dissipated due to the high-speed impact of the liquid during filtration, which not only ensures that there is no filtrate pollution caused by fiber detachment, but also avoids the traditional roller pressing treatment that causes the filter holes to be excessively clogged and shortens the life of the filter bag , At the same time, the pressure difference is small without affecting the flow rate.
