The surface of the basalt fiber filter bag is relatively smooth and the surface energy is low. After adding nano-SiO2 particles on the surface, the roughness of the surface of the basalt fiber can be improved, and more effective contact area can be increased.
Seven characteristics of basalt fiber filter bags:
1. Good temperature resistance, can be used for a long time below 320 degrees Celsius;
2. Good dust stripping property, low energy consumption for cleaning dust;
3. Good dimensional stability, and the shrinkage rate of the fiber itself is extremely low at the use temperature;
4. Good chemical resistance and weather resistance; no
5. Absorbs water, not hygroscopic;
6. High filtration efficiency, can reach more than 99.5%:
7. Long service life
