A method and system for controlling the mixing process of halogen-free cable materials.

Abstract

This invention discloses a method and system for controlling the mixing process of halogen-free cable materials. Based on the changing trends of shear force and material temperature, it determines whether the material matrix has reached a fusion state. Based on current and historical shear force and material temperature, it predicts the impact of adding liquid additives on material uniformity and adjusts the rotor speed of the mixing equipment to determine the timing of liquid additive addition. Based on the current shear force value, it determines the initial addition rate of the liquid additive. It acquires flow data reflecting the uniformity of material mixing in real time, and dynamically adjusts the initial addition rate based on the matching of the flow data with a preset stability range. It continuously monitors the dispersion process of the liquid additive, iteratively updating the addition timing and rate based on flow data and dispersion uniformity indicators to determine the final control scheme. This invention can dynamically decide the timing and rate of additive addition based on real-time data perception and intelligent iterative optimization, achieving precise, adaptive, and stable controllable high-quality production.
