Abstract

Komposittfibre nyttige for fremstilling av diafragmaer fremstilles ved blanding av en PTFE-dispersjon eller en PTFE-kopolymerdispersjon eller pulver med et findelt uorganisk materiale og et fiberdannende materiale, den resulterende blanding oppvarmes under skjærkraftbehandling til en temperatur hvor den skjærkraftbehandlede PTFE eller PTFE-kopolymer blir flytbar uten å vise tegn på spaltning mens dispersjonsmediet fjernes, hvis en PTFE-dispersjon eller PTFE-kopolymerdispersjon anvendes, blandingen avkjøles til under 70°C, og blandingen skjærkraftblandes ved under 70°C til å danne komposittfibre.
