Title: Bruno Heinrich: Innovator in Corrosion-Resistant Lining Technologies
Introduction
Bruno Heinrich is a notable inventor based in Duisburg, Germany. He has made significant contributions to the field of corrosion-resistant materials, particularly in the lining of metal tubing. With a total of 2 patents, his work has advanced the durability and longevity of metal pipes used in various industries.
Latest Patents
Heinrich's latest patents include innovative methods for lining metal tubing with a corrosion- and abrasion-proof cement mortar. One of his patents describes a blend of at least 35 percent alumina and not more than 45 percent calcium oxide mixed with sand at a sand-to-cement ratio of 1.8. This mixture is applied to the interior of a metal pipe using centrifugal application and compression. The resulting lining is then exposed to moisture for several hours, followed by exposure to warm steam for additional hours. Another patent focuses on lining a steel pipe internally with a cement mortar. This method involves adding a dispersion of a polymer, such as an acrylic resin, and a surface-acting resin, like a melamine resin, to a cement mortar with a sand-to-cement ratio of 1 to 3 and a water-to-cement ratio of 0.25 to 0.35. The resin is preferably about 10 parts by weight per 100 parts of cement. This blend is applied to the interior of a pipe, which is then rotated at an increasing speed to produce approximately 20-g forces on the material for compacting it for a few minutes.
