A kind of method that takes bamboo as raw material to prepare painting and calligraphy paper

Abstract

The invention discloses a method for preparing writing and painting paper by taking bamboo as a raw material. The preparation method comprises the following steps: washing, carrying out presoaking, cooking, grinding into pulp and rolling threads, washing, grinding into pulp and performing papermaking. According to the invention, bamboo is taken as the raw material, and wastewater produced in the production process is simpler to treat and easier to reach discharge standards, so that environmental protection is more facilitated; the method disclosed by the invention solves the technical problems of the current writing and painting paper such as high tightness, low bulk, low fracture length, bad absorption and poor flexibility, ink absorption and dimensional stability. The writing and painting paper prepared by the method disclosed by the invention not only is clear in rice paper grain texture, pure white and delicate in paper quality and high in ink moistening effect, and high in tension, but also is simpler in production process, short in production cycle, strong in production capacity, low in cost and suitable for large-scale industrialized production.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing painting and calligraphy paper using bamboo as a raw material. Background technique [0002] Calligraphy and painting paper is one of the "four treasures of the study" in my country. Good painting and calligraphy paper is deeply loved by calligraphers, painters and calligraphy and painting lovers. A good painting and calligraphy paper should have good ink, color and infiltration properties. In addition to certain reading and strength, it should also have certain quality indicators such as stiffness, bulk and water absorption. [0003] At present, leather and cotton are mainly used as the main raw materials for processing and production. Leather and cotton raw materials have the advantages of high cellulose content, low lignin, hemicellulose, miscellaneous cells and other substances, and the quality of the calligraphy and painting paper produced High-qua...

AI Technical Summary

Problems solved by technology

At present, bamboo pulp production enterprises are basically in a state of on and off, and the operating rate is low. The reason for the analysis is that the chemical indicators such as a-cellulose content, ash content, whiteness, and viscosity of the produced bamboo pulp can reach the level of chemical fiber. Factory standard requirements, but there are problems such as poor reaction performance, which is manifested in the process of producing viscose fibers in chemical fiber factories. Due to poor reaction performance, the viscose made has poor filtration performance, and the color is turbid and dark, which affects the smooth progress of the entire subsequent chemical processing. In severe cases, all the viscose liquid will be scrapped, which will lead to difficulties in selling bamboo pulp, and a large amount of bamboo pulp will be hoarded in the production enterprise, which will directly affect the economic benefits and sustainable and stable development of the enterprise.
