Title: The Innovations of Inventor Hans Thumm in Titanium Dioxide Suspension
Introduction
Hans Thumm, a proficient inventor based in Leverkusen, Germany, has made significant contributions to the field of materials science, particularly in the preparation of high solids content titanium dioxide suspensions. With a total of six patents to his name, Thumm’s work has garnered attention for its innovative approaches to improving industrial processes.
Latest Patents
One of Thumm's latest patents focuses on a novel process for preparing high solids content titanium dioxide suspension. This process involves slurrying finely divided titanium dioxide produced by the chloride process, without the use of dispersing agents. In this innovative method, the slurry’s multivalent anion content is controlled through specific dechlorinating agents, such as hydrogen peroxide and sodium hydrogen sulfite. The result is a filter cake that demonstrates either thixotropic properties or rigidity depending on the quantity of multivalent anions present. This distinct ability to manipulate the filter cake's consistency enhances its usability, especially in the paper industry, where titanium dioxide suspensions with solids content as high as 78% can be achieved.
Career Highlights
Thumm has worked with prominent organizations, including Kronos Titan GmbH and Kronos, Inc. His affiliations with these companies have enabled him to advance his research and implementation of novel processes in titanium dioxide production, solidifying his reputation within the industry.
Collaborations
Throughout his career, Hans Thumm has collaborated with notable colleagues such as Achim Hartmann and Siegfried Blumel. These partnerships have fostered a collaborative environment that drives innovation and advancement in the development of industrial applications for titanium dioxide.
Conclusion
With six patents to his credit, Hans Thumm stands out as an innovator in the field of titanium dioxide suspension preparation. His ability to manipulate chemical properties for improved industrial processes showcases his expertise and commitment to advancing materials science.
