Process Optimization for Calendered Paper
Created on 2025.12.20
The core process adopts a 6-pressure zone configuration mode, and the fibers are gradually compacted through a decreasing linear pressure distribution (from the first pressure zone of 32kN/m to the last pressure zone of 18kN/m). This process adopts a 6-pressure zone mode, reducing transmission power consumption by 15% and extending the equipment maintenance cycle to over 3,000 hours.
The improvement effect of the 6-zone sizing process on the performance of calendered paper is achieved by optimizing the zone configuration. This results in a significant reduction in the loss rate of calendered paper, an increase in the loose thickness of the finished paper, a glossiness of both sides reaching the 65-75% standard, and a roughness controlled within the range of ≤1.44μm.
