Title: Innovations by Rune Nygaard
Introduction
Rune Nygaard is an accomplished inventor based in Stathelle, Norway. He has made significant contributions to the field of polymer compounding, holding 2 patents that showcase his innovative approach to mixing devices and methods.
Latest Patents
One of his latest patents is a mixing device designed for compounding polymers through elongational deformation. This device features a casing with an inlet and an outlet, where the inner walls define an enclosure that communicates with both. A core is arranged within the enclosure, creating a mixing space that is divided into several slits and chambers by protrusions. The unique design allows for concentric arrangement around a common axis, tapering towards the outlet. The protrusions are strategically placed on the core and enclosure wall, with adjustable slit gaps to optimize the mixing process. This device is ideally incorporated into compounding equipment that includes a melting extruder, a homogenizing extruder, and a pelletizer.
Another notable patent is a method for compounding a multimodal polymer composition. This method involves combining a low molecular weight ethylene polymer with a high molecular weight ethylene polymer at a low temperature, specifically within a narrow range around the melting point of the low molecular weight polymer. The process is designed to occur without the addition of a heat transfer medium, ensuring a controlled compounding environment.
