Poplar rod core sulfate pulping process

The invention discloses a poplar rod core sulfate pulping process, and relates to the technical field of pulping. The preparation method comprises the following steps of: chipping and screening the remaining rod cores of poplar rotary-cut slabs; then performing feeding into a cooking pot for cooking operation, conducting washing operation in washing equipment, then feeding the product into a pressurized screen for screening operation, adopting hydrogen peroxide for bleaching and other operations, sending the treated product into a pulp storage tower for storage, reutilizing the poplar rod cores left after slab processing, and formulating a technological process according to material characteristics of poplar. The pulping cost is low, the pulp quality is good, and the requirements of high-grade paper production can be completely met. 本发明公布了一种杨木棒芯硫酸盐制浆工艺，涉及制浆技术领域，它包括以下制备步骤：将杨木旋切板皮剩下的棒芯进行削片、筛选操作，然后送入蒸煮锅进行蒸煮操作，放入洗涤设备中进行洗涤操作，再送入压力筛中进行筛选操作，采用过氧化氢进行漂白等操作，送入贮浆塔中进行储存，对经过板皮加工剩下的杨木棒芯进行再利用，并根据杨木的材质特性制定工艺流程，制浆成本低，浆料质量好，完全
