Problems solved by technology

[0002] Northwest China is a grape planting base, and a large number of grape branches are produced every year. For a long time, the grape branches after pruning in autumn have been digested by burning, and have not been used for other purposes, resulting in a huge waste of resources.

Embodiment Construction

[0016] The present invention uses grape branch as raw material, adopts caustic soda pulping process, the caustic soda pulping process is the same as the conventional caustic soda pulping process in the prior art, and its process includes material preparation, cooking, spraying, rough screening, pulp washing, screening, Dehydration and CEH three-stage bleaching.

[0017] The specific process is:

[0018] The exported grape branches are sent to the cutter roller mower through the belt conveyor for cutting. The cut grape branches enter the dust collector for dust removal and impurity removal. After that, it enters the pre-soaker and the cooking liquid for out-of-ball pre-soaking. Grape shoots and cooking liquid are mechanically potted through potners after pre-soaking in pre-soakers. The current process implements one-time charging, and after the cooking is completed, it is sprayed by the spray pot. Finally, CEH three-stage bleaching is carried out after preliminary screening...

Abstract

The invention relates to a grape branch pulp, which is prepared by using grape branches as materials and adopting soda-process pulping. The grape branch pulp adopts the grape branches which are not ever applied to the paper-making industry as the materials to prepare pulp, so that not only the effective utilization of the resources is achieved and the utilization value of the resources is greatly improved, but also the material source of paper-making and pulping is broadened; serious defects of wheat straw pulping materials are compensated, and a new pulp is added to the paper-making and pulping. In the invention , the soda process is used to prepare the grape branch pulp, so that the material utilization rate is high, the pulping rate is high, the yield is high, the coarse pulp yield can reach 40-45%, and the effective cooking time is only 2.7 hours, thus the production efficiency is high, the cooking quality is table, the production process is reliable, the cost is low, in particular the requirements to the material are low; besides, the pulp can be used to a bottom layer or a core layer of corrugated paper, and has certain popularization value.

Description

technical field [0001] The invention belongs to the technical field of application of papermaking and pulping methods, in particular to grape branch pulp. Background technique [0002] Northwest China is a grape planting base, and a large number of grape branches are produced every year. For a long time, the grape branches after pruning in autumn have been digested by burning, and have not been used for other purposes, resulting in a huge waste of resources. After observation, the raw material of pruned grape branches has no leaves, and its fiber structure is between Gramineae and wood fiber, and the fiber has the characteristics of toughness, softness and strong plasticity. Therefore, how to make full use of grape branches effectively and rationally has very practical significance for the energy saving and efficiency enhancement advocated by the country at present. Contents of the invention [0003] The purpose of the present invention is to provide a kind of grape branc...
