Problems solved by technology

[0002] At present, there are many types of household paper on the market, including roll paper, facial tissue, toilet paper, etc. Due to the different models, raw materials, and technology used by various manufacturers, the quality of the products produced is uneven, but the real ability Consumers are not satisfied enough. Household paper requires softness, good water absorption, and high dry and wet strength. However, the national quality standard for web paper has not yet been issued, and various enterprises use their own quality standards. Technical indicators are neither standard nor comprehensive

Embodiment 1

[0028]The weight content of sugarcane pulp: wood pulp is 75:25, and five desanding processes are adopted. (1) A large-hole gauze is installed in front of the pulp washing box to remove coarse sand; (2) Desanding is installed before refining (3) Set a medium-hole gauze after refining; (4) Set a grit settling plate before entering the pulp box; (5) Set a small-hole gauze at the lower part of the headbox of the paper machine net, to remove fine sand; and then use a 3.66-meter fourdrinier large-diameter double-cylinder papermaking temperature is easy to control, which can improve product quality. Use the HTDQ-N type pulp concentration automatic measuring and controlling instrument to measure the concentration of paper before and after different equipment. After the measurement and control, the pulp concentration is adjusted in time to ensure that the flow rate and sizing of each part are uniform, and then the flexible fiber-separating broom is used to make the pulp to a certain ex...

Embodiment 2

[0031] 1. The weight content of sugarcane pulp: wood pulp is 85:15, and five sand removal methods are used. (1) A large-hole gauze is installed in front of the pulp washing box to remove coarse sand; (2) Install before refining Sand remover to remove medium sand; (3) set a medium-hole gauze after refining; (4) set a grit settling plate before entering the pulp box; (5) set a small hole in the lower part of the headbox of the paper machine Hole gauze to remove fine sand; and then use a 3.66-meter fourdrinier large-diameter double-cylinder papermaking temperature is easy to control, which can improve product quality. Use the HTDQ-N type pulp concentration automatic measuring and controlling instrument to measure the concentration of paper before and after different equipment. After the measurement and control, adjust the pulp concentration in time to ensure that the flow rate and sizing of each part are uniform, and then use a flexible fiber-splitting broom to make the fibers ha...

Embodiment 3

[0034] 1. The weight content of sugarcane pulp: wood pulp is 80:20, and five sand removal methods are used. (1) A large-hole gauze is installed in front of the pulp washing box to remove coarse sand; (2) Install before refining Sand remover to remove medium sand; (3) set a medium-hole gauze after refining; (4) set a grit settling plate before entering the pulp box; (5) set a small hole in the lower part of the headbox of the paper machine Hole gauze to remove fine sand; and then use a 3.66-meter fourdrinier large-diameter double-cylinder papermaking temperature is easy to control, which can improve product quality.

Abstract

The invention relates to a papermaking method and especially relates to a method for producing paper for daily use from bagasse as a main raw material. The method comprises is characterized in that high-ratio sugarcane pulp and a small amount of wood pulp are used as main raw materials, a superhigh-concentration pulp refining technology is adopted, after pulp washing, the paper pulp is processed to form pulp having water content of 40-60wt% and then the pulp is grinded by a superhigh-concentration grinding machine, simultaneously, the automatic control system of a full-automatic beating and blending pulping technology is adopted, appropriate accessory materials are used, the concentration of paper pulp before and after each equipment treatment is adjusted, and a technology of high-speed hot air penetrating through paper pages is adopted. The method solves the problems of too high bagasse pulp paper tightness, insufficient bulkiness and a slow absorption speed.

Description

technical field [0001] The invention relates to a papermaking method, in particular to a method for producing household paper, especially roll paper, using bagasse as the main raw material. Background technique [0002] At present, there are many types of household paper on the market, including roll paper, facial tissue, toilet paper, etc. Due to the different models, raw materials, and technology used by various manufacturers, the quality of the products produced is uneven, but the real ability Consumers are not satisfied enough. Household paper requires softness, good water absorption, and high dry and wet strength. However, the national quality standard for web paper has not yet been issued, and various enterprises use their own quality standards. Technical indicators are neither standard nor comprehensive. [0003] There have been some relevant literature reports on the production of household tissue paper in China, such as: [0004] 1. Chinese patent, title: Method a...
