Traditional Chinese medicine biological agent for cooling pulping

Abstract

The invention provides a traditional Chinese medicine biological agent for cooling pulping. The traditional Chinese medicine biological agent is prepared from huaiyao, kudzu vine roots, cinnamomum camphora presl fruits and water. One Kg of traditional Chinese medicine biological agent is prepared from 0.05 Kg to 0.1 Kg of the huaiyao, 0.05 Kg to 0.15 Kg of the kudzu vine roots, 0.15 Kg to 0.25 Kg of the cinnamomum camphora presl fruits and the balance water. Pulping carried out through the traditional Chinese medicine biological agent belongs to the environment-friendly cooling pulping technology, the traditional Chinese medicine biological agent is used for the pulping raw material softening stage, softening time is short, and water obtained through the first step of softening is nearly neuter, and the raw materials are kept undamaged. When cooling pulping is carried out through the traditional Chinese medicine biological agent, toxicity, foam, smells, discharging and pollution to the air environment are avoided, and the produced pulp can be stored for a long time without color changing and deterioration; the longer the time is, the whiter the color will be. The number of adopted devices is smaller than that of devices adopted for thermalizing, operating is easier than that of thermalizing, electricity, water and labor can be saved, and the traditional Chinese medicine biological agent is low in cost, high in profit and free of sewage discharging and air pollution.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a traditional Chinese medicine biological agent for cold pulping. technical background [0002] my country is rich in wheat straw resources and has a long history of using wheat straw to make paper. At present, wheat straw cooking equipment includes steaming balls (intermittent cooking) and horizontal tube continuous steaming. Continuous steaming generally uses caustic soda method, and intermittent cooking uses caustic soda anthraquinone method or caustic soda Anafa. Generally, the sulfate method is not used, and the by-product of the process is colloidal black liquor, which accounts for more than 80% of the total papermaking pollution. At present, the black liquor, the pollution source of wheat straw pulping, is still a major problem in the world. [0003] The traditional ball steaming pulping method generally adopts high alkali, high temperature, anthraquinone, pulping met...

AI Technical Summary

Problems solved by technology

Moreover, the straw pulp produced by the cooking pulping process still has problems such as short fibers, too many fine fibers, poor tearing and folding resistance of the paper, and brittle paper.

Therefore, non-cooking process is the development trend of modern papermaking industry. CN1621610A discloses a pulping process of soaking wheat straw without cooking and soaking in chemicals. The soaking time of the medicine on the wheat straw is 24 hours, the soaking time is too long, and the efficiency is low. Therefore, it is necessary to find a high-efficiency, low-cost non-cooking medicine pulping process
