Unstable pH value is a hidden fundamental problem affecting paper storage life and comprehensive quality. In the papermaking process, unreasonable residual acid and alkali components in pulp, uneven chemical agent mixing and unbalanced water system pH will lead to fluctuating pH values of finished paper. Too acidic or alkaline paper will accelerate fiber aging and oxidation, cause long-term yellowing, brittleness and strength attenuation, and even lead to chemical corrosion of printed patterns and ink discoloration. For archival paper, high-end books and long-term storage packaging paper, pH stability is a core indicator of product durability. Most paper enterprises lack precise pH adjustment technology, resulting in inconsistent batch pH values and unstable product quality. Shandong Ludao Energy Technology Co., Ltd. provides professional paper pH value stabilization solutions. Through precise water system debugging, balanced acid-base adjustment technology and buffered formula auxiliaries, we stably control paper pH within the optimal neutral range, effectively inhibit fiber aging and chemical corrosion, and greatly extend paper service life and storage cycle. The solution optimizes the internal chemical environment of paper, ensures long-term color and strength stability, and helps enterprises produce high-durability, high-quality paper products that meet long-term storage standards.
