       The introduction of basalt high temperature dust bag to fill our own brand high temperature 350 ℃ grade synthetic fiber needle-punching filter media basalt blank, basalt needle-punching filter media as a new high temperature resistant materials can be used under the working conditions below 350 ℃ for a long time, and maintain the performance of the same, basalt high temperature dust bag due to the manufacturing process and the special nature of the raw material formula, basalt than similar products greatly improve the performance of dust removal efficiency and service life.

                                                     

         Basalt fiber as the filter material of dry filtration device, basalt high temperature resistant dust bag is mainly used for industrial dust removal and smoke and gas purification. Due to the excellent properties of basalt fiber itself such as high strength, high temperature resistance, corrosion resistance and low elongation, the filter bags made of basalt high temperature resistant dust bag have the following characteristics.

1. High mechanical strength, the breaking strength is generally above 3000N;

2. Low elongation, the elongation at break of basalt fiber itself is only 3%, so the filter bag made of it is stable in size;

3. Good mechanical properties, can be used under 300 ℃ temperature for a long time; instantly up to 350 °.

4. Basalt high temperature resistant dust bag has good corrosion resistance, can be used in acid and alkali atmosphere gas;

5. High void rate of fabric, smooth surface, good permeability, no-load pressure loss is only 2Pa;

6. Basalt high temperature dust bag dust collection efficiency, up to 99.5%-99%, especially for the diameter of the dust particles below 0.5mm, the effect is more obvious;

7. Strong adaptability to the concentration of dust in flue gas;

8. Basalt high temperature resistant dust bag can handle large amount of dust, easy to operate and maintain, and easy to clean dust;

9. Long service life.
