Method of making an electrically resistive sheet

摘要

A method for making a sheet of resistive material having randomly oriented conductive fibers with a density of approximately 50 to 300 milligrams per square meter. The fibers are weighed, mixed with a solvent, contained in a non-turbulent state. The solvent is withdrawn under pressure through a porous film and backing. A sticky sheet material is placed in contact with the film for transferring the fibers from the film to the sheet.
