Abstract: A method (500) for conditioning or hydrolysis of an extruded membrane is disclosed. The method (500) comprising ion exchange processes in divided electrochemical cells using a cation exchanger membrane. The method (500) includes extruding the perfluorosulfonyl fluoride membranes from perfluorosulfonyl fluoride granulate. The method (500) also includes using a pretreatment technique to increase the ionic conductivity of the extruded perfluorosulfonyl fluoride membranes before using the perfluorosulfonic acid membranes in electrolysis cells. The method (500) also includes applying a milder pretreatment technique by activating S—F bonds to execute nucleophilic exchange of the fluoride group in a reaction. The method (500) also includes hydrolyzing sulfonyl fluoride groups to sulfonic acid using triethylsilanol.

Abstract: A pressure hose (1) for a water-carrying system is shown and described, especially for connecting sanitary taps or for connecting parts of the water-carrying system, having a corrugated inner hose (2) made of plastic, wherein at least one hose end (3, 5) of the pressure hose (1) is provided with a connecting piece (4, 6), designed such that it differs from the inner hose (2), for joining the pressure hose (1) to a complementarily designed connecting piece of a sanitary tap and/or a part of the water-carrying system. According to the invention, it is provided that the inner hose (2) and the connecting piece (4, 6) are formed as one piece and the inner hose (2) and the connecting piece (4, 6) are preferably produced via extrusion in a common extrusion process.
