AI Technical Summary
Existing technologies for the purification and refining of polyetherketone polymers suffer from low control precision, resulting in low efficiency and poor quality. Furthermore, they lack a continuous understanding of the evolution and transition between intermediate material states across multiple stages, leading to control deviations during the drying stage.
By obtaining the concentration information and concentration decay rate of the effluent at the end of the solvent replacement stage, the release hysteresis index of the residual medium inside the polyetherketone polymer is determined. Combined with the initial control parameters, the drying control parameters of the drying stage are dynamically adjusted to achieve precise control of the internal state of the polymer.
It significantly improves the efficiency and product quality of polyetherketone polymer purification and refining, reduces energy consumption, and decreases scrap rate.
