摘要: Composite fibers useful for preparing diaphragms are prepared by (a) mixing a PTFE or PTFE copolymer dispersion or powder with a finely divided inorganic material and a fiber forming material, (b) shear heating the resulting mixture to a temperature at which sheared to PTFE or PTFE copolymer becomes flowable without showing signs of decomposition while removing the dispersion medium, if a PTFE or PTFE copolymer dispersion is used, (c) cooling the mixture to below 70° C., (d) mix shearing the mixture at below 70° C. to form composite fibers.

摘要: A process for the regeneration of plastic diaphragms is described, in which a mineral acid solution is mixed with a suitable corrosion inhibitor, this mixture is temperature controlled at from approximately 0.degree. to 100.degree. C., preferably 40.degree. to 80.degree. C., in particular 50.degree. to 70.degree. C., and passed through the diaphragm for from approximately 0.1 to 84 hours, preferably 1 to 72 hours, in particular 2 to 24 hours.
