| Abstract: | Based on the vacuum melting-gasification-decomposition-condensation technology, the separation of thermosetting resin and glass fiber of the main beam material of retired wind turbine blades is realized. [Display omitted] • First application of vacuum melting-gasification-decomposition-condensation technology enables high-efficiency. • Thermal decomposition characteristics reveal significant mass loss at 320–410 °C and an average heat release rate of 48.26 kW/m2. • Quantum chemical simulations identify bond dissociation energies (378.98–393.92 kJ/mol) and validate the four-stage separation mechanism. • Recovered glass fibers exhibit a Young's modulus of 33,946.76 MPa, high toughness, and promising recycling potential. The resource utilization of retired wind turbine blades is a key part of achieving the "dual carbon" goal. It is difficult to separate the adhesion between glass fiber and thermosetting resin in the main beam material of retired wind turbine blades, and the presence of thermosetting resin affects the recycling of glass fiber. The current separation technology has problems such as high technical difficulty and low availability of recycled products. In this study, it was verified that the vacuum melting-gasification-decomposition-condensation method could effectively separate glass fiber and thermosetting resin, and the thermosetting resin condensed in the pipe. The average heat release rate during decomposition is 48.26 kW/m2, and the heat treatment process is easy to control. The reaction sites were calculated and simulated by quantum chemistry, and the bond breaking energies of the thermosetting resin were 378.98 kJ/mol, 393.92 kJ/mol and 352.67 kJ/mol, respectively. The simulation results combined with the thermal decomposition characteristics show that the separation process goes through four parts: vacuum melting, gasification, decomposition and condensation. In addition, the material has a Young's modulus of 33946.76 MPa, and has strong toughness and potential for recycling. This paper may be the first study to recycle glass fibers using vacuum melting-gasification-decomposition-condensation technology. [ABSTRACT FROM AUTHOR] |
