Title: Innovations of Hans-Wilhelm Lieber
Introduction
Hans-Wilhelm Lieber is a notable inventor based in Berlin, Germany. He has made significant contributions to the field of plating and galvanizing technologies. With a total of six patents to his name, Lieber's work focuses on improving processes that enhance the efficiency and effectiveness of metal treatment.
Latest Patents
One of Lieber's latest patents is a method and device for regenerating tin-plating solutions. This invention addresses the regeneration of exhausted tin-plating solutions containing tin and copper ions, free complexing agents, and reducing agents. The process involves concentrating rinse water from the tin-plating process to a 10 to 15 percent dilution of the process solution. The resulting regenerating solution is then fed into an electrolytic cell, which consists of a cathode chamber, a middle chamber, and an anode chamber. This innovative approach allows for the cathodic deposition of copper and the enrichment of tin ions, ultimately enabling the regenerated solution to be reused in the tin-plating process.
Another significant patent by Lieber is a method for hot dip galvanizing metallic workpieces. This process eliminates the need for a treatment with fluxing agents. After cleaning, the workpieces are coated with a thin metal layer that replaces the traditionally applied fluxing agent layer. The workpieces are then immersed in a zinc melt while their surfaces remain dry, enhancing the efficiency of the galvanizing process.
