Embodiment 1

[0028] according to figure 1 The process flow chart shown is for seabuckthorn pulping. First cut the seabuckthorn wood into 15mm seabuckthorn slices through a slicer, and then remove the sand dust and impurities in the seabuckthorn through a sand remover.

[0029] The material is decomposed into thin strips by a slitting machine, and then 1kg of steam is introduced for 3 hours of softening and pre-steaming treatment; then it is sent to a thread rolling machine for thread separation and kneading, and after crushing and rubbing, it is formed into coarse strips. Fibrous;

[0030] Finally, three-stage refining is carried out, which are: first-stage refining treatment by high-consistency decomposing machine, the concentration of slurry is 35%; secondary refining treatment by medium-consistency refining machine, slurry concentration is 70%; low-consistency refining The pulp machine is subjected to three-stage refining treatment, and the slurry concentration is 90%. After the thre...

Embodiment 2

[0033] First cut the seabuckthorn branches into 20mm seabuckthorn branch sections by a slicer, and then remove the sand dust in the seabuckthorn by a sand remover.

[0034] Then the material is decomposed into thin strips by a slitting machine, and then 2 kg of steam is introduced for 2 hours of softening and pre-steaming treatment; then it is sent to a thread rolling machine for thread separation and kneading, and after crushing, rubbing and separation, coarse strips are formed. Fibrous;

[0035] Finally, three-stage refining is carried out, which are: first-stage refining treatment by high-consistency decomposing machine, the concentration of slurry is 40%; secondary refining treatment by medium-consistency refining machine, slurry concentration is 60%; low-consistency refining The pulp machine is subjected to three-stage refining treatment, and the slurry concentration is 80%. After the third stage of refining, it is screened and sent to the pulp storage tank for standby, ...

Embodiment 3

[0038] First cut the seabuckthorn wood into 18mm seabuckthorn slices through a slicer, and then remove the sand dust in the seabuckthorn through a sand remover.

[0039] Then the material is decomposed into thin strips by a slitting machine, and then 2 kg of steam is introduced for 2 hours of softening and pre-steaming treatment; then it is sent to a thread rolling machine for thread separation and kneading, and after crushing, rubbing and separation, coarse strips are formed. Fibrous;

[0040] Finally, three-stage refining is carried out, which are: first-stage refining treatment by high-consistency decomposing machine, the concentration of slurry is 38%; secondary refining treatment by medium-consistency refining machine, slurry concentration is 65%; low-consistency refining The pulp machine is subjected to three-stage refining treatment, and the slurry concentration is 85%.

[0041] The pulp yield of the slurry was 76.5% after being washed by conventional methods. After p...

Abstract

The invention provides a sea buckthorn pulping method which adopts mechanical pulping technique; with the method, raw material has wide sources, and a mechanical environment-friendly pulping mode without adding alkali and other chemical substances is adopted; the pulp yield rate reaches 76.5 to 82.5 percent and no pollution produces in the production process.

Description

technical field [0001] The invention relates to a pulping method in the papermaking industry, in particular to a seabuckthorn pulping method and seabuckthorn pulp. Background technique [0002] Corrugated paper and composite cardboard are green and environmentally friendly materials that are light in weight, less in material, low in cost, high in strength, good in cushioning performance, sound-absorbing and heat-insulating, and easy to recycle. In recent years, as the packaging industry has vigorously advocated "substituting paper for plastic and paper for wood", this green environmental protection material, as a new type of green packaging material, is gradually being valued and vigorously developed in the field of packaging. This will lead to the development of lighter packaging materials to reduce shipping costs. Waste of wood in wooden pallet packaging and wooden box packaging, white pollution in plastic foam pad packaging, etc. These packaging materials have relatively...
