摘要： A blend of fluorocarbon polymers for incorporation into an asbestos fiber slurry for forming into a diaphragm is disclosed. The blend comprises fluorocarbon polymer fibers and fluorocarbon polymer chunks of certain sizes in certain weight ratios. Also disclosed is a diaphragm comprised of the asbestos and two types of fluorocarbon polymers, as well as a method of making same.

摘要： In making diaphragms and diaphragm-coated electrodes for electrolytic cells, such as those used for the electrolysis of brine to produce chlorine and caustic soda or caustic potash. by depositing a slurry of asbestos fibres and polytetrafluoroethylene on a substrate and heating to dry the resultant mat and fuse the polytetrafluoroethylene, the latter is in the form of fibrids made by applying a compressive shear action to particles and the heating step is carried out so that the polytetrafluoroethylene fibrids are fused and cause to shrink.
