Introduction: Fiberglass stitched mat with carbon veil is especially designed for conductive profiles: the six-party tube,cable,cable trough. Carbon fiber has good conductivity, thus can minimize the build-up of static electricity that could prove dangerous when in contact with explosive liquids and gases.. It is also widely used in chemical enterprise,coal-burning enterprises for dust extraction, demist, desulfuration. Collection coefficient 99.7%,while the traditional water dust removal method collection coefficient is 80%. Carbon veil is usually 30G/M2.
