Basalt fiber needle felt in basalt single fiber disorderly staggered interludes, form non-directional three-dimensional microporous structure. As a result of 7-9μm finer fibers large specific surface area, porosity of about 80%, boron, for advanced air filtration and purification, insulation sound absorption, insulation materials, hot-rolled steel mirror, aluminum and high-temperature soft bedding materials.
2. Applications
1) Superior air filtration system; the electronics industry filtration, sound absorption, insulation, anti-vibration systems;
2) Chemical, toxic and harmful gases, dust filtration system;
3) car muffler, ships, ship insulation, thermal insulation, silencers system.
