Friction coefficient stability is a key basic index affecting automated packaging and high-speed paper conveying efficiency. Unstable surface friction of paper is a common hidden defect in mass production, manifested as excessive friction in partial batches causing paper jams, scratch wear and equipment overload; or too low friction leading to sheet sliding, stacking dislocation and positioning deviation during high-speed conveying and automatic packaging. This subtle index fluctuation is easily ignored in conventional quality testing, but directly affects the operation stability of fully automated production lines. The root causes include uneven surface micro-roughness, irregular auxiliary agent distribution and inconsistent fiber exposure degree. Most paper mills adjust calendering pressure or surface coating to change friction, which can only achieve single friction value adjustment and cannot maintain long-term batch stability, resulting in frequent seasonal and batch equipment adaptability failures. Shandong Ludao Energy Technology Co., Ltd. develops professional paper friction coefficient stabilization solutions. By homogenizing paper surface micro-texture and balancing surface functional agent distribution, we lock the friction coefficient in the optimal processing range. The solution realizes consistent friction performance of full-page and full-batch paper, eliminates automatic conveying jams and sliding dislocation defects, improves the matching degree between paper and automated equipment, and stabilizes intelligent production efficiency.
