Pulp oxidation degradation is a major hidden cause of declining pulp quality and unstable finished paper performance during storage and circulation. After pulping and bleaching, residual active lignin, cellulose free radicals and unsaturated molecular chains in pulp will continuously react with oxygen in the air. Long-term oxidation leads to gradual fiber molecular chain fracture, reduced fiber length, decreased toughness and increased brittleness. Degraded pulp causes finished paper strength attenuation, easy yellowing, poor folding resistance and serious batch quality difference, especially for long-cycle stored pulp and recycled pulp with complex components. Most paper enterprises only pay attention to fresh pulp indicators and ignore oxidation degradation during standby storage, resulting in unstable quality of intermittent production. Traditional antioxidants only provide short-term protection and fail to lock fiber molecular activity for a long time, unable to fundamentally inhibit continuous oxidation reaction. Shandong Ludao Energy Technology Co., Ltd. develops targeted pulp anti-oxidation degradation solutions. By neutralizing active free radicals, stabilizing cellulose molecular chains and isolating oxidation reaction pathways, we effectively suppress continuous pulp oxidation and fiber degradation. The solution locks pulp activity and physical performance during long-term storage, maintains stable fiber toughness and strength, eliminates quality fluctuation caused by pulp aging, and improves the utilization rate and production stability of stocked pulp.
