Title: Yuuzi Washio: Innovator in Amorphous Silica Technology
Introduction
Yuuzi Washio is a notable inventor based in Niigata, Japan. He has made significant contributions to the field of materials science, particularly in the development of innovative fillers for various applications. With a total of three patents to his name, Washio's work has garnered attention for its practical applications and unique properties.
Latest Patents
One of Washio's latest patents focuses on an amorphous silica filler. This filler possesses a large apparent specific gravity, despite having a BET specific surface area ranging from 200 to 500 m²/g. It has an oil absorption amount as low as 50 to 120 ml/100 g and an agglomeration degree defined by the ratio of silica elementary particle diameter to primary particle diameter ranging from 10 to 50. The nearly spherical particulate structure of this amorphous silica is distinct from that produced by conventional gelation methods. The filler exhibits excellent handling, processability, dispersion properties, and abrasion resistance. When used as an anti-blocking agent, it enables the production of resin films that are transparent and scratch-resistant, free from fisheyes or voids. Additionally, this amorphous silica is utilized in heat-sensitive recording papers, where it suppresses ground fogging, enhances image concentration, and allows for the application of highly viscous coating solutions.
