Unstable pulp drainage efficiency is an important factor leading to fluctuating paper machine speed and inconsistent batch quality. In actual production, changes in pulp temperature, concentration, pH value and auxiliary dosage will cause great fluctuations in pulp drainage speed. Unstable drainage leads to uneven moisture content of wet paper web, inconsistent forming thickness, and frequent paper breakage during high-speed operation. Many paper mills can only reduce machine speed to adapt to unstable drainage, which seriously restricts production capacity improvement and increases unit energy consumption. Conventional drainage agents are greatly affected by external conditions, with poor anti-interference ability and cannot achieve long-term stable drainage effect. Shandong Ludao Energy Technology Co., Ltd. provides professional pulp drainage stability optimization solutions. By adopting anti-interference composite drainage aids and optimizing pulp system adaptability, we maintain stable and efficient drainage speed under different production conditions, ensure uniform moisture filtration and consistent fiber forming, effectively reduce wet paper breakage rate and speed limitation problems. It stably improves paper machine operating efficiency and output, unifies batch product quality, and helps enterprises realize high-speed, high-efficiency and standardized large-scale production.
