PERFECCIONAMIENTOS EN LA HERMETIZACION DE CELULAS ELECTROLI-TICAS PARA LA PRODUCCION DE CLORO

摘要

An electrolytic cell for electrolysis of an aqueous sodium chloride solution is provided with a closure for its open side which is resistant to degradation by chlorine and ozone. The cover has an external elastomeric layer which is stable when exposed to ozone and a polytetrafluoroethylene layer facing the aqueous solution which resists attack by chlorine, and intermediate polyamide, polyester or fiberglass mesh on synthetic rubber layers. The synthetic rubber layer is chloroprene vulcanized with lead oxide.
