In addition, the anti-pollution and anti-blocking composite material has good pressure-bearing performance and strong anti-pollution capability, is not easy to be blocked, and is more popular in the market. The precision of the ultrafiltration membrane filter element is between 0.01 and 0.1 micrometer, compared with the ultrafiltration membrane filter element, the ultrafiltration membrane filter element has lower precision, and can finish filtration through the gravity of water, namely self-weight water outlet without pressurization. When setting up ultrafiltration filter core, generally need cooperate and use structures such as resin, active carbon to filter great impurity in advance, form inclosed filter equipment, simultaneously, still need set up the filter screen between structures such as resin, active carbon and water, water can only permeate towards the filter screen. However, if the holes of the filter screen are too large, the purpose of separating water from small particulate matters such as resin, activated carbon and the like cannot be achieved, and a filter layer cannot be formed; if the filter holes of the filter screen are too small, air in the intervals of small particles such as resin, activated carbon and the like can only go upwards due to the airtight bottom space during filtration, and too small filter Kong Youhui forms a layer of water film due to the tension of water, the water film can block the air in the filter layer from being discharged outwards, tap water cannot permeate into the filter layer, the pressure balance between the filter layer and the filter layer is achieved, and finally the effect of dead weight filtration of water can not be achieved.
