Title: Richard O. Kirk: Innovator in Polymer Extrusion Technology

Introduction

Richard O. Kirk is a notable inventor based in Lake Jackson, TX (US). He has made significant contributions to the field of polymer extrusion technology, holding a total of 7 patents. His work focuses on improving processes and equipment used in the manufacturing of low bulk density polycarbonate materials.

Latest Patents

Kirk's latest patents include a method for extruding polycarbonate of low bulk density. This innovative process aims to reduce polymer surging, lower pressure and temperature fluctuations, and minimize polymer degradation while maintaining a good overall throughput rate during the plasticating and extruding of low bulk density polycarbonate materials. The method utilizes a two-stage extrusion screw with a feed section that has a constant channel depth of at least about 12 percent of the screw diameter, along with a transition section featuring a compression ratio of at least about 3:1. The thermoplastic low bulk density polycarbonate materials are extruded through a die into sheets, profiles, or films.

Another significant patent is for a high-efficiency extruder. This invention consists of a corotating multiple-screw extruder that includes first and second intermeshing screws with more than one flight. The first screw is designed with first and second segments that are paired with corresponding segments of the second screw. Notably, on the first segment of the first screw, the height of the first flight is less than that of the second flight, and similarly, on the second segment of the second screw, the height of the first flight is less than that of the second flight.
