Abstract

The invention discloses a mechanical pulping method for biological bacteria liquid, and belongs to the field of papermaking and pulping. The main technical problem to be solved is that the waste liquor for pulping pollutes the environment. The method is that: compound bacteria serve as bacterial strains; the compound bacteria comprise white rot fungi, actinomycete, and methane bacteria in a mass ratio of 1-3: 1-3: 1; and the density of the mixed bacterial liquid is 60,000,000 / ml. The method comprises the following steps: degrading the raw materials with the mixed bacterial liquid after swelling, thread rolling and extrusion; grinding coarsely; grinding finely; bleaching or not bleaching; and washing the liquid to prepare the pulp. The method is mainly used for pulping herbal materials and has the advantages of no pollution or discharge of waste liquor in the pulping process, recyclable liquid, low production cost and simple process.

Description

technical field

[0001] The invention relates to a biological bacteria liquid mechanical pulping method, which belongs to the field of paper pulping. Background technique

[0002] Pulping technology: It is the process of removing lignin and pectin and other substances from plant straw, branches, trunks and other materials through degradation (or dissociation) to obtain fibrous substances. Fiber is the main component of papermaking.

[0003] Plant straw is mainly divided into fibrous and non-fibrous. Fibers are soft, while non-fibrous substances are hard. Non-fibrous substances are mainly composed of lignin, hemicellulose, pigments, ashes, pectin, silicon and other powdery substances. These non-fibrous substances play a major role in plant straws. Lignin supports the hardness of straws. Pigments are the blood of straws. They help plants absorb nutrients and transfer water. Cellulose is tightly surrounded and dispersed by them.

[0004] In the pulping process, to separate th...
