Embodiment 1

[0023] The present embodiment provides a kind of production method of high-yield bamboo pulp, comprises the steps:

[0024] (1) Bamboo slicing: bamboo is cut into width and is 5mm, the length is the bamboo chip of 20mm;

[0025] (2) Bamboo slice screening: Screen the bamboo slices processed through step 1 slices, remove the thick slices with a length greater than 35mm and the bamboo chips produced in the cutting process by screening, and the thick slices are screened and utilized after cutting again. The bamboo chips are transported out of the screening system for other purposes;

[0026] (3) Bamboo chip washing: the bamboo chip obtained through step 2 is washed with water, to remove pollutants such as silt, dust, ironware in the bamboo chip, the bamboo chip after washing is filtered and dehydrated, and the water content is 45% The situation of carrying out the next step bamboo chip impregnation;

[0027] (4) Impregnation of bamboo chips: The impregnation of bamboo chips is ...

Abstract

The invention discloses a production method of high-yield bamboo pulp, and relates to the technical field of pulping and papermaking production. In order to solve the technical problems of low yields,high energy consumption, heavy pollution and high costs in the existing sulfate method bamboo pulp production processes, the method comprises the steps of bamboo slicing, bamboo chip screening, bamboo chip washing, bamboo chip dipping, extrusion treatment, chemical treatment, high-concentration pulping and latency elimination treatment. By adopting the method for pulping, high-temperature and high-pressure conditions are not needed, so that the production process is low in energy consumption and light in pollution, and meanwhile, the method has the advantages of high paper pulp yield and lowcost.

Description

technical field [0001] The invention relates to the technical field of pulping and papermaking production, and more specifically relates to a production method of high-yield bamboo pulp, which is used to obtain high-yield bamboo pulp in the papermaking process. Background technique [0002] The paper industry is an important basic industry of the national economy and plays a vital role in the construction of our country's material civilization and spiritual civilization. The remarkable feature of the paper industry is the raw material processing type, which consumes a lot of fiber raw materials. For example, it takes 5.5m2 to produce 1t of pulp. 3 about 2.5 tons of dry bamboo, about 3 tons of dry rice straw. Wood is the most commonly used and high-quality fiber raw material in the world's papermaking industry. However, my country's wood resources are very short, and there is very little wood used for pulping and papermaking. For a long time, the shortage of fiber raw mater...
