Abstract

The invention discloses a production method of total-bamboo-pulp low-basis-weight high-strength corrugated base paper. The method includes: selecting pulp, defibering, beating, preparing materials andmaking paper. The production method has the advantages that the paper produced by the method is low in basis weight and good in strength, and the paper is low in cost, environmentally friendly and good in color as compared with base paper produced by reclaimed pulp in the existing market; the 100% natural-color bamboo pulp is used as the raw material, dependence on forests is reduced, and evidentenvironment protection benefits are achieved; the high-yield natural-color bamboo pulp is used as the raw material to perform clean pulping, and the produced paper is healthy and safe to human bodiesand packaged objects; the method is low in production cost and capable of effectively relieving the contradiction of regenerated-fiber shortage; the high-yield natural-color bamboo pulp is high in lignin content, the produced paper is good in stiffness, high in mechanical strength and good in moisture resistance, and the problem that corrugated base paper can be easily affected by dampness can besolved effectively.

Description

technical field [0001] The invention relates to the technical field of pulping and papermaking, in particular to a method for producing all-bamboo pulp low-quantity high-strength corrugated base paper. Background technique [0002] Corrugated base paper is a black and thick product in people's minds, and it is mainly used to support the keel of the packaging box. The strength of the packing box depends on the strength of the base paper. According to the requirements of use, there are ordinary corrugated base paper and high-strength corrugated base paper. However, the raw materials used in these products are basically recycled fibers. For cost reasons, little virgin fiber is added. Therefore, the slurry used in a packaging box may have been used many times. Due to the different times of recycling, it will inevitably lead to fluctuations in the quality of some products. influences. What is more obvious is that the recycled pulp still contains a small amount of ink compone...
