FLEXIBLE INTERMEDIATE BULK CONTAINER WITH INDUCTION CONTROL

摘要

A method, apparatus and system is provided for both (1) decreasing electrostatic discharges to reduce the potential for incendiary discharges caused by electrostatic charges in flexible containers such as flexible intermediate bulk containers (FIBCs) and (2) decreasing the induction on isolated conductors nearby the container to reduce the potential for incendiary discharges from the isolated conductors

1. A controlled-conductive flexible fabric container with a reduced energy of electrostatic discharge for use in a combustible environment, comprising:
a woven fabric configured to form the flexible fabric container having one or more side walls; said fabric including a plurality of quasi-conductive fibers having corona discharge points, said fibers including one or more filaments, said filaments sized and shaped to effect: corona discharge at said corona discharge points while having resistance to avoid incendiary discharge at ends of said filaments and along the lengths of said filaments at a rate that results in incendiary type discharges in the combustible environment; and while grounded, there is sufficient charge dissipation within the container in order for the residual charge to be maintained below that required to cause potentials to be induced on nearby isolated conductors, said potentials sufficient to cause an incendiary discharge in the combustible environment.
