Title: Ernst Puchel and His Foamed Gypsum Invention.
Introduction
Ernst Puchel is an inventor associated with Hofheim, Germany, and Hoechst Aktiengesellschaft. His recorded patent describes a process for producing foamed gypsum and constructional elements made from the material.
Latest Patents
Puchel’s listed patent, “Process for Preparing Foamed Gypsum and Constructional Elements Composed,” concerns mixing gypsum with water and additives that liquefy the gypsum and regulate its setting period. A mixture of isocyanate compounds and polyurethane preadducts is then added. Foaming begins after approximately five minutes and is completed after about 20 minutes, producing set gypsum with a density of 0.45 to 0.8 g/cc, compared with 1.66 g/cc for unfoamed gypsum. The process can also be carried out in molds to create shaped components, including sandwich elements. Puchel is credited with 1 patent.
Career Highlights
Puchel’s documented patent work reflects an application of polymer-related additives to gypsum processing. The invention’s reduced-density material and moldable construction elements point to potential uses in building products.
Collaborations
The supplied information identifies Dieter Stahl as Puchel’s coworker. The patent is associated with Hoechst Aktiengesellschaft.
Conclusion
Ernst Puchel’s recorded invention combines gypsum with chemical additives to produce lightweight foamed material and shaped construction elements.
