Embodiment 1
[0018] A pulp preparation method for hemp paper ultra-thin paper, comprising three steps of crushing hemp, beating and making pulp, wherein,
[0019] 1) Crush the hemp. After the fermentation is completed, transfer the hemp to the water mill, and repeatedly roll it until the hemp fibers are completely dispersed; the hemp grinding adopts three processes: front, middle and back. The first three hours are rinsed and rolled with clean water, and the previous process is washed and rolled. The solid residues of lime, dregs and antioxidants in the washing, soaking, steaming and fermentation processes are removed by rolling; in the middle 4 hours, use low-concentration clarified lime water instead of clean water to wash and roll; in the latter 10 hours, again Rinse and compact with clean water until the hemp fibers are completely dispersed;
[0020] The low-concentration clarified lime water is prepared by mixing quicklime and water at a mass ratio of 0.06:100, then fully reacting, an...
Embodiment 2
[0024] A pulp preparation method for hemp paper ultra-thin paper, comprising three steps of crushing hemp, beating and making pulp, wherein,
[0025] 1) Crush the hemp. After the fermentation is completed, transfer the hemp to the water mill, and repeatedly roll it until the hemp fibers are completely dispersed; the hemp grinding adopts three processes: front, middle and back. The first three hours are rinsed and rolled with clean water, and the previous process is washed and rolled. The solid residues of lime, dregs and antioxidants in the washing, soaking, steaming and fermentation processes are removed by rolling; in the middle period of 3 hours, use low-concentration clarified lime water instead of clean water to wash and roll; in the later period of 11 hours, again Rinse and compact with clean water until the hemp fibers are completely dispersed;
[0026] The low-concentration clarified lime water is prepared by mixing quicklime and water at a mass ratio of 0.08:100, then...
Embodiment 3
[0030] A pulp preparation method for hemp paper ultra-thin paper, comprising three steps of crushing hemp, beating and making pulp, wherein,
[0031] 1) Crush the hemp. After the fermentation is complete, transfer the hemp to the water mill, and repeatedly crush until the hemp fibers are completely dispersed; the hemp grinding adopts three processes: front, middle and back, and the first 4 hours. The solid residues of lime, skin dregs and antioxidants in the washing, soaking, steaming and fermentation processes are removed by rolling; in the middle period of 5 hours, use low-concentration clarified lime water instead of clean water to wash and roll; in the later period of 8 hours, again Rinse and compact with clean water until the hemp fibers are completely dispersed;
[0032] The low-concentration clarified lime water is prepared by mixing quicklime and water at a mass ratio of 0.1:100, then fully reacting, and taking the supernatant;
[0033] 2) Beating, transfer the milled...
