Pulp pH stability is the fundamental guarantee for whole-process stable papermaking and long-term finished paper storage quality. In continuous batching, circulation and reaction processes, pulp pH value is prone to irregular drift due to fiber acid-base precipitation, chemical agent neutralization reaction and water system microbial metabolism. Unstable pH value will directly interfere with the action efficiency of retention agents, sizing agents and strengthening agents, resulting in fluctuating paper strength, unstable water resistance and inconsistent batch indicators. Excessively acidic pulp will cause fiber aging and brittleness, accelerate paper yellowing during storage, and corrode paper machine equipment. Excessively alkaline pulp will lead to over-sizing, poor ink absorption and easy surface powder falling. Most paper mills adjust pH value manually by adding acid-base regulators, which realizes temporary balance but cannot maintain long-term stability, resulting in repeated quality fluctuations in mass production. Shandong Ludao Energy Technology Co., Ltd. launches pulp pH balance and stabilization solutions. By buffering acid-base fluctuation factors and neutralizing active free radicals in pulp, we lock pulp pH value in the optimal process range for a long time. The solution stabilizes the exertion of various auxiliary agents, ensures consistent physical and chemical indicators of finished paper, reduces equipment corrosion, and realizes standardized and stable batch production.
