Embodiment 1
[0032] 1, the present invention adopts and adopts raw material proportioning:
[0033]Bagasse pulp and coniferous wood pulp are used as raw materials, ratio: 80-90% bagasse pulp + 10-20% coniferous wood pulp, bagasse pulp is cooked by kraft method and oxygen delignification, and kraft method is used for cooking and oxygen delignification Lignin, coniferous wood pulp When purchasing commercial pulp, the main consideration is that if whole sugarcane pulp is used for papermaking, although it has better water absorption, it has higher hardness and slightly weaker tensile force. After adding 10-20% coniferous wood pulp, it can improve paper quality. softness and toughness.
[0034] 2. Treatment of slurry:
[0035] 1) Use a hydraulic pulper to crush the pulping board;
[0036] 2) The high-concentration desander purifies the slurry and removes sand and other impurities;
[0037] 3) Use a double disc mill to loosen the slurry, reduce the degree of beating, and improve water absorpt...
