AI Technical Summary
Traditional polyethylene materials struggle to balance yield strength and toughness at low temperatures. Reinforcing agents tend to agglomerate in the matrix, and the process parameters are poorly optimized, resulting in unstable performance that fails to meet the application requirements of high-end structural components.
A multi-stage synergistic modification system is adopted, including raw material screening, dynamic crosslinking, nano-dispersion and stretching orientation. The raw material ratio and process parameters are optimized by combining algorithms such as the firefly algorithm, the gray wolf optimization algorithm and the least squares support vector machine. Precise optimization is achieved through the closed-loop interaction of multiple algorithms.
The material maintains excellent toughness and structural strength in low-temperature environments, improving the consistency and stability of material performance, broadening application boundaries, and adapting to high-end application scenarios with harsh low-temperature working conditions.
