Method of sealing separators for electrolytic cells for alkali metal chloride brines

摘要

Separator materials suitable for use in electrolytic cells, for example, for the electrolysis of alkali metal chloride brines, are sealed by a method which comprises coating the sections to be sealed with a synthetic thermoplastic sealing agent and ultrasonically sealing the coated portions. The method permits the sealing-in-place of separator materials and allows them to be unsealed and resealed without damage to the separators.
