| titleOfInvention | PROCESS FOR PREPARING ASBEST-FREE PASSED DIAPHRAGMENTS FROM POLYTETRAFLUOROETHYLENE |
| abstract | The invention relates to a process for producing an asbestos-free continuous PTFE diaphragm for electrolysis cells, preferably for chloralkali electrolysis. The aim of the invention is to provide a cost-effective method for the production of microporous diaphragms. According to the invention, the object is achieved by thoroughly dry mixing a dry mixture of suspension-type PTFE crude polymer with 1.5% to 12.5% highly functionalized PTFE crude polymer and a finely divided pore former in the ratio by volume of 1: 5 to 5: 1. This mixture is dispersed with a volatile organic liquid having a density of 1.3 to 2.4 g / cm3 and poured onto a horizontally leveled mold, the organic liquid removed by evaporation drying and the preformed layer thus formed at 320 to 380 ° C and a pressure of 1 compressed up to 10 MPa. {asbestos-free continuous flow diaphragm; Electrolysis cell; Chlor-alkali electrolysis; Method; highly functionalized polytetrafluoroethylene; Preszverfahren; pore former; suspension polymer} |
