Title:
RECYCLED RESIN PRODUCTION METHOD, RECYCLED RESIN PRODUCTION DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/048031
Kind Code:
A1
Abstract:
The present invention provides a method for producing recycled resin with uniform viscosity through addition of additive resin, the method being capable of being executed even when only one kneading machine is used. The method for producing recycled resin comprises: a process for supplying recovered resin to a kneading machine; a process for supplying two or more types of additive resin with different viscosities to the kneading machine; a process for kneading the recovered resin and the two or more types of additive resin to obtain recycled resin; a process for measuring the viscosity of the resin being kneaded or the recycled resin obtained by kneading after the start of kneading; and a process for changing the supply amount of each of the two or more types of additive resin on the basis of the measured viscosity.
