Title: Koichi Fukushima: Innovator in Polyester Resin Technology
Introduction
Koichi Fukushima is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of polyester resin technology, holding a total of 5 patents. His innovative methods have advanced the processes involved in mixing and thickening polyester resins.
Latest Patents
Fukushima's latest patents include a "Method for continuously mixing polyester resins" and a "Method for thickening a polyester resin." The first patent describes a device designed to enhance the thickening effect of a feed resin without pre-drying. This device features a chamber with a mixing rotor that continuously mixes the resin between a feed port and a discharge port. It also includes multiple vent ports connected to vacuum pumps to reduce pressure in the chamber. A screw feeder is utilized to introduce a viscosity-increasing chemical agent into the chamber, ensuring that the feeder remains isolated from the reduced pressure areas. In operation, the feed resin enters the chamber from a hopper, where it is dehydrated while being mixed in a drying section. After the chemical agent is added, the resin is continuously mixed in a thickening section while being deaerated.
The second patent outlines a method for thickening a polyester resin by first introducing the feed resin through a port and dehydrating it under reduced pressure in a drying section. A chemical agent is then added to the dehydrated feed resin and mixed in a thickening section while also being deaerated. This chemical agent serves to either increase the viscosity of the feed resin or prevent its reduction.
