Title: The Innovations of Fumiaki Hirata: Pioneering Polyisocyanate Technologies
Introduction
Fumiaki Hirata, an accomplished inventor based in Sodegaura, Japan, has made significant contributions to the field of chemical engineering, particularly in the production of polyisocyanate. With two registered patents to his name, Hirata's work focuses on efficient production methods that prioritize environmental sustainability.
Latest Patents
Hirata’s latest innovations include a novel polyisocyanate production method and a corresponding production system. The method efficiently utilizes hydrogen chloride, a secondary byproduct of the polyisocyanate production process, thus minimizing environmental impact. The process begins with the reaction of chlorine and carbon monoxide to produce carbonyl chloride in a dedicated reactor. This carbonyl chloride is then reacted with polyamine in an isocyanate producing reactor to yield polyisocyanate.
Hirata's production system incorporates a purification step for the hydrochloric gas, which is subsequently oxidized to regenerate chlorine. This newly produced chlorine is cycled back into the process, enhancing the overall efficiency. Additionally, he has developed an aqueous polyurethane resin characterized by its stable emulsion and controlled balance between hydrophilicity and hydrophobicity. The innovation provides a method for producing the aqueous polyurethane resin, resulting in films with desirable permeability and stability.
