Title: Innovations by Shu Muraoka
Introduction
Shu Muraoka is a notable inventor based in Iwaki, Japan. He has made significant contributions to the field of waste treatment through his innovative methods. With a total of 3 patents, Muraoka's work focuses on improving the efficiency of recycling electronic substrates and coated wires.
Latest Patents
One of Muraoka's latest patents is a method for treating waste electronic substrates. This method involves carbonizing waste printed circuit boards together with a calcium compound at temperatures ranging from 400° C. to 600° C. in a non-oxidizing atmosphere. The process aims to fix halogens contained in the board as calcium halides and to melt the solder, allowing for the easy separation of mounted parts from the board. After carbonizing, the materials are crushed and sieved into fine particles, medium particles containing mounted parts, and coarse particles containing board pieces.
Another significant patent is the treatment method of coated wire. In this method, a coated wire, which is a metal wire coated with resin, undergoes low-temperature heating in a non-combustion atmosphere alongside an alkali. This process embrittles the coating resin, which is then crushed to separate the coating resin from the metal wire.
