Claims (8)

1. Förfarande för framställning av ett hydrauliskt permeabelt dimensionsstabilt diafragma pä en med häl försedd katod för använd-ning i en klor-alkalielektrolyscell, vid vilket förfarande beredes en suspension av fibrös asbest och en partikelformig, fluorhaltig termoplastisk polymer, som är mekaniskt och kemiskt resistent gente-mot cellomgivningen, vilken polymer föreligger i tillräcklig mängd för att förhindra väsentlig svällning av diafragmat, känne-t e c k n a t därav, att a) katoden som skall överdragas införes i suspensionen och ut-fälles en jämn blandning av asbestfibrer och partikelformig polymer därpä med hjälp av vakuum, b) den överdragna katoden uttages fr&n suspensionen och utsättes under tillräckligt läng tid för en tillräcklig temperatur för att bringa polymeren att mjukna och flyta och bringa polymeren att binda samman närbelägna fibrer utan att bilda ett kontinuerligt polymeröver-drag pä fiberytan, och c) den diafragmaöverdragna katoden kyles tili i huvudsak rums-temperatur, för erhällande av ett diafragma, som är dimensionsstabilt under celldriftsbetingelser, vilket utmärkes av asbestfibrer uppbärande ett diskontinuerligt smält polymeröverdrag.
2. Förfarande enligt patentkravet l,kännetecknat därav, att polymeren utgör 5-70 vikt-ί? av den totala mängden polymer-asbest.
5. Förfarande enligt patentkravet 1 eller 2, kännet ec k -n a t därav, att koncentrationen av asbest plus polymer i suspensionen är 5-30 g/1. Förfarande enligt patentkravet 1, 2 eller 3, känne -t e c k n a t därav, att den överdragna katodytan i huvudsak torkas innan den utsättes för polymermjukningstemperaturen.
