1. Uniform pore size, stable pore shape, high separation rate;
2. High porosity, low filtration resistance, and high infiltration efficiency;
3. High temperature resistance, can be used normally below 280 ℃ (wet state);
4. Good chemical stability, acid and alkali corrosion resistance (PH2-12), and antioxidant properties;
5. No particles fall off, so as not to cause secondary pollution to the original solution. Good mechanical performance, low pressure difference, large flow rate, filter press and suction filter, easy operation;
6. Strong antimicrobial ability, does not interact with microorganisms. Can be regenerated online, easily disappears, and has a long service life (usually several times that of membrane filters);
