Problems solved by technology

[0002] Nowadays, with the progress of society, the improvement of people's living standards and the quality of cultural life, the consumption of various papers has increased significantly. The raw materials used in traditional papermaking methods are mainly wood pulp and straw pulp, and the use of wood pulp to make paper has caused a large number of forests to be destroyed. , the ecology deteriorates; straw pulp papermaking reduces the organic matter returned to the field, and the soil fertility decreases, which will cause a lot of waste of forest and pasture resources in the long run. The patent application No. 01126541.8 discloses a palm husk Pulping and papermaking method, this method utilizes palm husk as raw material, after pretreatment of palm husk, cooking, black liquor separation, washing, purification, beating, papermaking and other process steps, various paper products can be produced, but In this method, the source of raw materials is single and the scope of use is narrow; the pretreatment process is not thorough, the cost of raw material transportation is large, and it brings troubles to subsequent process steps
