Method for improving biological pulping by utilizing ozone and surfactant and biological pulp

Abstract

The invention provides a method for improving biological pulping by utilizing ozone and a surfactant. The method comprises the following steps of: 1, cleaning a bagasse raw material, then rolling threads, and standing for dehydration after thread rolling; 2, cooking the material obtained in the step 1, and introducing ozone in the cooking process; 3, carrying out pulp washing on the cooked bagasse; 4, adding a biological enzyme and a surfactant into the pulp obtained by pulp washing, and standing for a period of time under a closed condition; and 5, grinding the slurry obtained in the step 4 to obtain the required slurry. According to the method, the bio-enzyme and the surfactant are added before pulping, so that a better pulping effect can be achieved.

Description

technical field [0001] The invention relates to the field of pulping, in particular to a method for improving biological pulping by utilizing ozone and surfactants and biological pulping. Background technique [0002] Papermaking is world-famous as a great invention of the working people in ancient China. The papermaking process can be divided into two technological stages, namely pulping and papermaking. Pulping is to separate the fibers in plants, which are washed, screened, and crushed successively. , drying to make a slurry; and the papermaking process is to successively dilute, disperse, screen, form, and dry the concentrated slurry to obtain paper. The pulping process is particularly important in these two process stages, which directly determines the quality of the paper after papermaking. [0003] Although the papermaking industry is one of the important foundations of my country's economy, it is also an industry that consumes a lot of energy and resources, produces...

Problems solved by technology

However, the process is complicated, and the raw materials need to be soaked in acid and alkali before being treated with enzymes.

There are the following disadvantages: one is that the type of enzyme is single, and the time for enzyme leaching is longer; the other is that new equipment needs to be added, and the cost increases; Industrial Production and Use

[0010] At present, the enzymes used in biopulping are only a combination of several enzymes. The role of each enzyme is single, and the use of some enzyme-related auxiliary products is still rare, and the removal effect on lignin is not ideal.
