Papermaking method with bagasse as raw material

Abstract

The invention discloses a papermaking method with bagasse as a raw material. The method takes the bagasse as the raw material and comprises the following steps of material collecting and edge breaking; chopping; thread rolling; pulp washing; grinding; pulp forming; dosing; pulp boiling and papermaking. The method is a papermaking method with low development cost, convenience, practicality, and lowlabor intensity and using the bagasse as the raw material. The method turns waste into wealth, takes full advantage of resources, and provides a new raw material resource for papermaking industry; the required equipment is simple, and common enterprise workers can easily master the method; there is no need to add any chemical additive during pulping and grinding processes; the method plays a positive role in reducing cutting down forest due to papermaking demands and protecting ecology; the method breaks through traditional papermaking technologies and takes full advantages of the bagasse; the method is a pure natural and 'three waste' discharge-free papermaking technology.

Description

technical field [0001] The invention relates to a papermaking method, in particular to a papermaking method using bagasse as a raw material. Background technique [0002] China is a big country of paper making and has a long history. The papermaking raw materials are mainly wood, grass, and bamboo. The papermaking process is slightly different due to different raw materials. The basic process of using wood to make paper is: cutting→cooking→bleaching→pulping→papermaking. Feasible, but due to the adoption of the cooking process, the energy consumption is high and the pollution is very large; when bleaching, the use of caustic soda, hydrogen peroxide, urea, etc. also inevitably pollutes the environment. [0003] At present, there are many tropical plants in tropical and subtropical regions. South my country is a subtropical region, which is suitable for planting sugarcane. Sugarcane is an annual or perennial perennial tropical and subtropical herbaceous plant, which belongs to...

[0005] In recent years, although someone has invented a method of extracting fiber with bagasse, the extracted fiber content is only 20% to 40% of the original, and there are still many short fibers that are discharged along with the waste during the fiber extraction process. Afterwards, the stacking of the waste left behind causes secondary environmental pollution
