Description
Technical Field
The invention belongs to the technical field of papermaking, and particularly discloses a production system of natural-color bamboo pulp instant high-thickness paper.
Background
At present, the household paper in the market mainly takes the shape of a roll and a box as toilet paper, and mainly takes the white color. The daily paper mainly aims at water absorption, comfort and quick solubility, most of the current daily paper products do not pay attention to quick solubility, and the phenomenon of sewer blockage caused by the daily paper also happens. With the continuous improvement of the living standard of people, the demand for the use comfort of the household paper is increased, and in order to increase the use comfort of the household paper, compared with the common toilet paper, the existing high-quality household paper has high thickness, especially for the toilet paper with high quick solubility, so that the instant solubility of the household paper is poorer.
Because the bleached paper contains fluorescent whitening agent, cancerogenic substances and other harmful chemical substances can be generated, in order to prevent the paper from damaging human bodies and the environment, the paper on the market tends to use natural-color toilet paper, the raw material for manufacturing the paper is changed from wood pulp to bamboo pulp, and the instant property of the toilet paper is further poor due to the good toughness of fibers in the bamboo pulp paper.
At present, natural color high-thickness household paper is prepared by using bamboo pulp, and the process generally comprises the steps of crushing the bamboo material, steaming the bamboo material, pulping, desanding, pulp mixing and papermaking. In the process of crushing bamboo, after bamboo is cleaned, bamboo joints are cut into small sections by a cutting machine to realize crushing. However, if the bamboo is cut and broken by the cutting knife directly, the bamboo fiber positioned on the cutting surface can be damaged. In addition, in order to increase the instant solubility of the natural-color high-quality paper, a proper amount of reagents such as a softening agent, a stripping agent and the like are generally required to be added in the production process, and the step is completed in the pulp mixing process, however, the reagents such as the softening agent, the stripping agent and the like are not easy to be fully mixed with the bamboo pulp due to high concentration of the bamboo pulp, and further the prepared natural-color high-thickness paper for daily use cannot be poor in instant solubility.
