Abstract

A process for producing a honeycomb of synthetic-resin material for use as the collector electrode of an electrostatic precipitator comprises assembling the honeycomb from plate strips having the cross section of sheet piling and made by hot molding from unsaturated polyester resins, glass fibers and nonwoven external covering fabrics of synthetic fiber. The honeycomb structure, which has a hexagonal ducts, is then provided with a shell of glass fiber and polyester resin by a winding operation. Conductive pigments, such as carbon and metal oxides, and flame-inhibiting additives can be incorporated in the unsaturated polyester resin.
