Abstract
A method of recycling a thermosetting polymer object of arbitrary shape includes: operating a fixture device to hold and rotate the thermosetting polymer object; operating a smart and modularized water jet cutter device to shatter the thermosetting polymer object outside-in into a wet polymer powder; drying the wet polymer powder; flattening the partially dried wet polymer powder; completely drying the flattened wet polymer powder; and separating the dried polymer powder into first and second groups, the particle size of the first group dried polymer powder being greater than a predetermined value, the particle size of the second group fried polymer powder being not greater than the predetermined value.

A method of recycling a thermosetting polymer object of arbitrary shape, the method comprising:
- operating a fixture device to hold and rotate the thermosetting polymer object of arbitrary shape about a predetermined axis;
- operating a smart and modularized water jet cutter device to shatter the thermosetting polymer object held by the fixture device in an outside-in manner into a wet polymer powder, the smart and modularized water jet cutter device including a smart and multi-axis robotic arm, a rotatable multi-water jets cutter head package that is co-movably disposed on the smart and multi-axis robotic arm, and a centralized controlling unit operable to control the smart and multi-axis robotic arm and the rotatable multi-water jets cutter head package for shattering the thermosetting polymer object of arbitrary shape, the rotatable multi-water jets cutter head package including a jets head that is co-movably connected to the robotic arm, and a plurality of rotary jets nozzles that are disposed on the jets head and that are divided into two groups in mirror symmetry relative to a short axis of the jets head, the rotary jets nozzles being rotatable relative to the jets head, the centralized controlling unit being operable to control three-dimensional movement path of the robotic arm, a Reynolds Number and a kinetic energy of a fluid ejected by the rotatable multi-water jets cutter head package, a dynamic contact time between the fluid ejected by the rotatable multi-water jets cutter head package and the thermosetting polymer object, and an attacking angle of the jets head of the rotatable multi-water jets cutter head package, the cleanness of the thermosetting polymer object and the particle size of the wet polymer powder being adjustable through controlling the centralized controlling unit and selection of the modularized program of the smart and modularized water jet cutter device;
- centrifugally and partially drying the wet polymer powder to form a partially dried wet polymer powder;
- flattening the partially dried wet polymer powder to form a flattened wet polymer powder with a predetermined thickness;

- and
- separating the dried polymer powder in an enclosed space into a first group and a second group, the particle size of the dried polymer powder in the first group being greater than a predetermined value, the particle size of the dried polymer powder in the second group being not greater than the predetermined value.
