Latest Patents

Rolf Mangen holds a patent for a method of lining a steel pipe internally with a cement mortar. This innovative process 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. The specific formulation includes 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 around 10 parts by weight per 100 parts of cement. This blend is applied to the interior of a pipe, which is then rotated at a gradually increasing speed to produce approximately 20-g forces on the material, compacting it effectively for several minutes.
