AI Technical Summary
In the current production process of flat base paper, the control of beating degree relies on a single variable and lacks the synergistic optimization of multiple process variables, resulting in unstable performance of finished paper and difficulty in meeting the uniformity and long-term reliability requirements of high-voltage insulation materials.
By integrating a freeness sensor and a fiber morphology analyzer, dual-dimensional monitoring is achieved. Through multi-variable collaborative regulation, freeness data and fiber morphology information are collected in real time. Combined with the data analysis module and the control module, synchronous closed-loop control is performed to precisely regulate the beating degree.
It achieves stable control of the beating degree within the target range of 65°SR to 85°SR, improves the electrical insulation strength and mechanical property uniformity of the finished paper, as well as the fiber distribution uniformity, and can correct deviations in the beating process in real time and predictively regulate the fiber brooming trend.
