Basalt filter bag is a kind of high temperature filter material product, which is made of basalt fibre as the main raw material and filter material through special process. Basalt filter bag has the following features and advantages:
High temperature resistance: basalt filter bag can be used for a long time in a high temperature environment, according to different manufacturing processes and formulations, its temperature resistance level can reach 350 ℃, to fill the international high temperature synthetic fibre needle punched filter media blank.
High mechanical strength: basalt fibre itself is high strength, made of filter bags are generally more than 3000N fracture strength, able to withstand large mechanical loads.
Dimensional stability: Due to the low elongation of basalt fibre, the filter bag size is stable and not easy to deform due to temperature change or mechanical vibration.
Corrosion resistance: basalt filter bag has good corrosion resistance, can be used in acid, alkali atmosphere of the gas, suitable for a variety of industrial environments.
High filtration efficiency: the filter bag has smooth surface, good air permeability, low no-load pressure loss, high dust collection efficiency, and good filtration effect on dust particles below 0.5mm in diameter.
Strong adaptability: Basalt filter bag has strong adaptability to the concentration of dust content in flue gas, handling large amount of dust, convenient operation and maintenance, and easy to clear dust.
Long service life: due to the performance advantages of the material itself and the special manufacturing process, the basalt filter bag has a long service life.
Material in addition to basalt fibre, may also be compounded with glass fibre, P84, PTFE, etc., in order to adapt to different working conditions, can meet the needs of industrial dust removal and flue gas purification.
Overall, basalt filter bag as a new type of high temperature filter material, in the iron and steel, electric power, chemical industry and other industries of high temperature flue gas dedusting and purification has a wide range of application prospects.
