The advent of basalt high temperature resistant dust removal bag has filled the gap of my country's own brand high temperature 350 ℃ synthetic fiber needle-punched filter material basalt. As a new type of high temperature resistant material, basalt needle-punched filter material can be used for a long time under the working conditions below 350 ℃ , and keep the performance unchanged, basalt high temperature dust removal bag due to the particularity of the manufacturing process and raw material formula, the performance of basalt has greatly improved the dust removal efficiency and service life compared with similar products.

Basalt fiber is used as the filter material of dry filtration device, and basalt high temperature dust removal bag is mainly used for industrial dust removal and smoke and gas purification. Due to the high strength of basalt fiber itself, high temperature resistance, corrosion resistance, low elongation and other excellent properties, the filter bag made of basalt high temperature dust removal bag has the following characteristics:
1. High mechanical strength, breaking strength is generally above 3000N;
2. The elongation is low, and the elongation at break of the basalt fiber itself is only 3%, so the filter bag made of it is dimensionally stable;
3. Good mechanical properties, can be used for a long time at a temperature of 300 °C; it can reach 350 ° in an instant.
4. Basalt has good corrosion resistance and can be used in the gas of acid and alkali atmosphere;
5. The fabric has high porosity, smooth surface, good air permeability, and no-load pressure loss is only 2Pa;
6. Basalt high temperature resistant dust removal bag has high dust collection efficiency, up to 99.5%-99%, especially for dust particles below 0.5mm in diameter, the effect is more obvious;
7. Strong adaptability to flue gas dust concentration;
8. Basalt high temperature resistant dust removal bag handles a large amount of smoke and dust, which is convenient for operation and maintenance, and easy to clean;
9. Long service life.
