He has made significant contributions to the field of materials science, particularly in the production of thermoplastic and polystyrene resin foams. With a total of 3 patents to his name, Ishikawa's work has advanced the technology and processes involved in foam production.
Latest Patents
Ishikawa's latest patents include a process for producing thermoplastic resin foams. This innovative process involves mixing a thermoplastic resin, a blowing agent, and other necessary components in a molten state before extruding the mixture to expand. The apparatus he developed features a metering zone at the front end of the rotating shaft in an extruder, a kneading zone closer to the rear end, and multiple perforated plates mounted on the shaft's surface. This design ensures uniform mixing and consistent extruding operations.
Another significant patent is for producing polystyrene resin foam. This process involves supplying an extruding machine with polystyrene resin, a fine inorganic powder, and a highly volatile foaming agent. The mixture is heated to melt and extruded into a lower pressure zone. By adding an alcoholic ester of a higher fatty acid, the process guarantees the production of aesthetically appealing foams that are free from staining and malodor, while also minimizing fire hazards.
