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...

Abstract

The invention relates to the technical field of chemical materials, particularly relates to a pulp preparation method of ultrathin hemp paper and aims at solving the technical problem of providing a pulp preparation method of ultrathin hemp paper. According to the technical scheme, the pulp preparation method of the ultrathin hemp paper comprises three steps of (1) grinding hemp, transferring the fermented hemp into water-powered roller and repeatedly grinding until the hemp fiber is completely dispersed and adopting front, middle and rear three procedures before grinding the hemp; (2) pulping, transferring the ground hemp into a pulping pool, adding clear water, fully stirring, dispersing the hemp fiber gathered into aggregates after being dispersed due to the grinding action, and then controlling water to obtain the hemp fiber; and (3) preparing pulp, mixing the hemp fiber with water-leaving pulp evenly to prepare the pulp, wherein the water-leaving pulp is prepared from a separating agent and water and the separating agent is prepared from the components in parts by weight: 3-5 parts of a pearl grass extract, 1-2 parts of citric acid and 3-5 parts of distilled water.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a pulp preparation method for making hemp paper ultra-thin paper. Background technique [0002] At present, most of the cicada wing ultra-thin paper is handmade by ancient methods, and there are few technologies that can make handmade ultra-thin paper. There are many rare books, calligraphy and painting works using cicada wing paper in various museums. The restoration process is inseparable from high-quality handmade ultra-thin paper. [0003] Hemp paper is made of exquisite materials, using high-quality natural hemp as raw material, and following the traditional techniques and methods since the Han Dynasty to process paper. It has the advantages of "long fiber, strong pulling force and bright color". The technological process is reasonable, including: dismantling, sorting, cutting, cleaning, soaking, steaming, fermentation, grinding, beating, water control, pulping,...
