Abstract
Patente de Patente:<B>"CéLULA DE ELETRóLISE DE CLORO-áLCALI COM DIAFRAGMA APERFEIçOADA"<D>. A invenção refere-se a uma célula de eletrólise de cloro-álcli como diafragma que compreende uma tampa, uma base condutora para suportar os ânodos e um cátodo na forma de uma caixa dotada de parede interna, parede externa e garras tubulares feitas de uma malha ou folha perfurada coberta com um diafragma poroso. Uma ou mais folhas de cobre para a distribuição da corrente elétrica são fixadas nas paredes externas do cátodo. A conexão entre as folhas de cobre e as paredes externas do cátodo é feita por meio de parafusos com a interposição de um elemento condutor e deformável dotado de elasticidade residual sob compressão. As soldas para a montagem das paredes do cátodo são isentas de tensões internas.
