A High Strength and Low Energy Consumption Refining Process for Household Paper

Abstract

The invention relates to the technical field of paper-making pulping, in particular to a pulping technology of high-strength low-energy-consumption paper for daily use. The pulping technology comprises the steps that firstly, 45-65% of bamboo pulp and 35-55% of wood pulp are mixed and prepared to obtain mixed pulp, then after being fully soaked and moistened in a pulp soaking tower filled with a softening liquid, the mixed pulp is subjected to slag removal by a high-concentration slag remover, then the concentration of the pulp reaches 20-25% through a concentration device, then the pulp is delivered to a high-concentration pulping machine for pulping, and an enzyme additive is added for high-concentration pulping. The pulping technology of the high-strength low-energy-consumption paper for daily use has the advantages that the prepared pulp makes the paper strength improved significantly, the content of fine fibers in white water is reduced, the fiber loss is reduced, the energy consumption is reduced, the production technology is simple, and the pulping technology is suitable for large-scale industrialized production.

Description

technical field [0001] The invention relates to the technical field of papermaking and pulping, in particular to a high-strength and low-energy consumption household paper refining process. Background technique [0002] The production process of household paper mainly includes a pulping section and a papermaking section. Raw materials are made into pulp with a certain concentration through pulping, desanding, refining and other processes, and then enter the papermaking section of the paper machine through wire pressing and drying. In the prior art, when wood pulp or bamboo pulp is used as the raw material for pulping, the pulping concentration is generally below 10%, the pulp concentration is low, the specific surface area of ​​the fiber is small, the water absorption and swelling of the fiber is not enough and the binding force of the fiber is low. Weak problem, when the pulp enters the refiner for beating under low-concentration state, the fibers are easily cut off, resul...

Problems solved by technology

In the prior art, when wood pulp or bamboo pulp is used as the raw material for pulping, the pulping concentration is generally below 10%, the pulp concentration is low, the specific surface area of ​​the fiber is small, the water absorption and swelling of the fiber is not enough and the binding force of the fiber is low. Weak problem, when the pulp enters the refiner for beating in a low-concentration state, the fibers are easily cut off, resulting in the precipitation of a large number of fine fibers, resulting in poor strength of the finished paper, and low-concentration beating consumes a lot of energy
