Technical Field

The invention relates to the field of bamboo pulp production, in particular to a method for manufacturing bio-mechanical pulp by taking moso bamboo as a raw material.

Background

Bamboo pulp is one kind of paper pulp. The bamboo is prepared from bamboo such as moso bamboo, phyllostachys pubescens and Sagittaria sagittifolia by common sulfate method and caustic soda method. Or removing green from tender bamboo, and pickling with lime to obtain semi-cooked material. The fiber shape and length are between those of wood and grass fiber. Easy sizing, and the bamboo pulp is paper pulp with medium fiber length, and is fine and soft. The pulp has high bulk, tearing strength and lower breaking strength and tensile strength. The bamboo fiber has two cell wall structures, one is a multilayer structure, the fiber wall is formed by alternately combining wide layers and narrow layers, the wide layers and the narrow layers respectively account for 4-5 layers, the wide layers are light in color, the cellulose density is low, the narrow layers are deep, namely the lignin density is high, the fiber mainly exists at the peripheral part of the vascular bundle and accounts for about 1/2 of the total number of the fiber. Another type of fibrous cell wall is thick and has narrow cells, the inner layer of the fibrous secondary wall is mainly composed of two wide layers, and the outer wide layer is much wider than the inner wide layer. From the electron microscope picture stained by potassium permanganate, the fibers are stained more than the fibers of the former multilayer structure type, namely, the fibers are technically degraded to a lower degree, and the fibers are mostly present in the middle of the fiber population of the vascular bundle tissue. The bamboo fiber wall has less pores than needle fiber and small pores, so that the medicine liquid permeating during steaming is slow. Cell corner regions in bamboo are often vacant, especially between parenchyma cells.

The traditional pulping method has low production efficiency, can generate a large amount of chemical waste and is not environment-friendly enough.

Based on this, the invention designs a method for manufacturing the bio-mechanical pulp by using moso bamboo as a raw material, so as to solve the problems.
