Title: Kenichi Hirao: Innovator in Hydraulic Substances
Introduction
Kenichi Hirao is a notable inventor based in Otsu, Japan. He has made significant contributions to the field of hydraulic substances, particularly through his innovative use of high tenacity acrylonitrile fibers. With a total of 2 patents, Hirao's work exemplifies the intersection of material science and engineering.
Latest Patents
Hirao's latest patents focus on the development of hydraulic substances reinforced with high tenacity acrylonitrile (AN) fibers. The first patent describes a process for producing hydraulic substances that exhibit high bending strength and large impact strength. These hydraulic substances are created by dispersing a hydraulic substance and high tenacity AN fibers in water, along with the application of nonionic or cationic high molecular flocculants. The resulting slurry undergoes a paper-making process, leading to enhanced performance characteristics.
The second patent details the production of high tenacity acrylonitrile fibers themselves. These fibers are composed mainly of acrylonitrile polymers and possess impressive mechanical properties, including a tensile strength of at least 10 g/d and a degree of crystalline orientation measured by X-ray diffraction. The production process involves extruding an acrylonitrile polymer solution, coagulating the filaments, and subjecting them to a series of drawing and drying steps to achieve the desired properties.
