Abstract

The invention discloses a method for manufacturing bio-mechanical pulp by using moso bamboo as a raw material, which comprises the following steps: collecting the moso bamboo raw material, slicing and crushing the moso bamboo raw material, soaking the crushed fragments in a soaking pool, introducing a biological decomposer into the soaking pool, introducing the decomposed raw material into a rubbing machine for rubbing, placing the raw materials subjected to filament rubbing operation in a steam engine to be subjected to steam preheating treatment, placing the preheated raw materials in the soaking pool again to be subjected to secondary soaking treatment, and allowing the raw materials subjected to secondary soaking to be guided into a pulping machine to be subjected to primary pulping operation; and introducing the material subjected to the primary pulping operation into a fine pulping machine for secondary fine grinding operation. According to the method for manufacturing the bio-mechanical pulp by taking the moso bamboo as the raw material, a mechanical and biological mixed pulping method is adopted, so that on one hand, the paper pulp efficiency can be effectively improved, and on the other hand, waste discharge can be reduced.

Description

technical field [0001] The invention relates to the field of bamboo pulp production, in particular to a method for manufacturing biomechanical pulp from moso bamboo. Background technique [0002] Bamboo pulp is a kind of pulp. It is made from moso bamboo, nanzhu, cizhu and other bamboo materials, and is usually prepared by sulfate method and caustic soda method. There are also young bamboos that are degreened and marinated with lime to make semi-clinker. Fiber shape and length, between wood and grass fibers. Easy to apply glue, bamboo pulp is medium fiber length pulp, fine and soft. Pulp has high bulk and tear, but low bursting strength and tensile strength. It has high mechanical strength. Bamboo fiber has two cell wall structures, one is a multi-layer structure, and the fiber wall is composed of wide layers and narrow layers alternately. The wide layers and narrow layers each account for about 4 to 5 layers, and the wide layers The color is lighter, indicating that th...
