Title: Wilhelm Franschitz: Innovator in Membrane Technology
Introduction
Wilhelm Franschitz is a notable inventor based in Neuhausen, Switzerland. He has made significant contributions to the field of membrane technology, holding 2 patents that showcase his innovative approaches to manufacturing membranes and microfilters.
Latest Patents
Franschitz's latest patents include a process for manufacturing a partially permeable membrane. This process involves etching a 20-200 µm thick aluminum foil in a non-recrystallized condition at a current density ranging from 2-20 kA/m². The surface is treated to prevent hydration reactions, making the membrane suitable for ultrafiltration, gas separation, or pervaporation, and it can be combined with a polymer membrane for enhanced functionality. His second patent details a process for manufacturing a microfilter, where a foil with an aluminum content of at least 99.95% and a thickness of 20-250 µm undergoes recrystallizing annealing and is etched in stages at a constant current density of 0.01 to 2 kA/m². This microfilter also receives a stabilizing after-treatment to prevent hydration reactions.
