Embodiment Construction

[0019] The production process flow of the present invention includes a material preparation and cooking process flow; a washing and bleaching process flow; the specific flow is as follows.

[0020] 1 Preparation and cooking process

[0021] The exported jiji grass is sent to the knife roller mower through the belt conveyor for cutting. The cut scorpion grass enters the horn (double cone) dust collector for dust removal and impurity removal. After that, it enters the prepreg for out-of-ball prepreg. After the presoaker is pre-soaked, the potting grass and the cooking liquid are mechanically loaded into the pot through the pot loader. The current technology implements secondary charging, the first charging uses 70% of the cooking liquid, and the second charging uses 30% of the cooking liquid. After the secondary charging is completed, the lid is idling, and the idling is carried out for 20 minutes to heat up and cook. After the cooking is completed, it is sprayed by the spra...

Abstract

The invention relates to a preparation method for an achnatherum splendens pulp. The achnatherum splendens is adopted as a raw material to prepare the achnatherum splendens pulp through an alkali cooking process. The achnatherum splendens, which has never been adopted in paper industry, is adopted as the raw material by the present invention, such that new varieties of raw materials of pulp manufacture are developed, market share of the raw materials of the pulp is improved, and serious shortage of achnatherum splendens resource is made up. The raw material provided by the present invention has advantages of low cost, easy cutting off and short. With the present invention, qualified rate of scraps of straws is high than 85%; filling amount (volume of spherical digester: 25m<3>) is estimated to 6.0-6.5 tons; during bleaching process, the achnatherum splendens pulp is easy to be washed and bleached, and has an advantage of higher whiteness than the whiteness of the achnatherum splendens and the whiteness of reed pulp, wherein the whiteness of the bleached achnatherum splendens pulp can reach 78% or higher. The preparation method for the pulp provided by the present invention has advantages of flexible and simple operation, stable and reliable production process. According to the present invention, the achnatherum splendens bleached pulp is more applicable for pulp ratio and quality control in a papermaking plant.

Description

technical field [0001] The invention belongs to the technical field of application of papermaking and pulping methods, in particular to a method for preparing pulp. Background technique [0002] Jiji grass is a perennial herbaceous family. Many stems, thin leaves, clustered. It usually lives in slightly alkaline soil and is especially resistant to drought. It is a common plant on the edge of the Gobi Desert in Northwest China. The shape of the grass is slender, the stem is solid, and the tissue structure is tight. It contains active ingredients from the inside to the outside, and the skin is hard. Compared with the reeds and bamboos of the same weight, the effective ingredients of the bamboo are more than those of the reeds, and the impurity content is extremely low. . However, for a long time, Achnatherum splendens has been mainly used as forage grass, or as woven fabrics and brooms, and its utilization value is low, and its effective components have not been fully util...
