Abstract

The invention provides a calendaring method of aramid insulation paper, and relates to the field of polymer chemistry and polymer processing, and the calendaring method comprises the following steps: step 1, preheating the aramid insulation paper; 2, feeding the base material into a calender, and carrying out calendering treatment at the set temperature, pressure and linear speed by adopting a multi-stage pressure control system; and step 3, monitoring the thickness uniformity and the surface quality of the aramid insulation paper in real time through an online detection system. The method has the advantages that by adopting the synergistic effect of multi-stage progressive pressure control, high-precision temperature regulation (+ / -2 DEG C) and linear speed optimization and combining machine vision on-line detection and real-time feedback, the defects of a traditional calendaring process are effectively overcome, the surface smoothness, thickness uniformity and mechanical performance of the aramid insulation paper are remarkably improved, and the quality of the aramid insulation paper is improved. And the accuracy, efficiency and quality consistency of the production process are greatly improved, and meanwhile, surface defects such as stripes and ripples are avoided.
