Basalt fiber high temperature filter bag use high-tensile strength basalt fiber. Which is resistant to high temperatures, alkali, acid oxidation. The ability of water-repellent and the size, fit the harsh environment of dust-cleaning, enhanced the efficiency of dust cleaning and prolong the service life.
Advantages
1. With excellent heat-resistance, filter bag can be used quite a long time under 300°C(the application temperature of fiberglass high temperature is 260°C, P84 240°C, Aramid Fiber bag 200°C);
2. Good bug dust peeling property, low consumption for cleaning dust.
3. With good dimensional stability, contraction rate of fiber itself under application temperature is zero;
4. Has the resistance of acid, alkali and chemical corrosion, weatherproof, filter bag performance is stable except hydrofluoric acid(HF), high concentrations of strong acid, strong alkali;
5. Non-absorbent, non-moisture-absorbent;
6. The efficiency of filtering can reach 99.5% or more;
7. Long service life.
Application field
Apply to cement plant, steel works, thermal power plant and gravity precipitator.
