Paper making method for straw fiber pulping by 'enzymatic conversion and puffing'

Abstract

This invention relates to one enzyme and puffing weed fiber pastry paper processing method, which combines biological science, life science and mechanic process to realize paper process without dirty water discharge. The method is characterized by the following: through grinding for clutter and mixture removing and cutting into short weed fiber materials into press machine; adding H2O2 solution and fiber enzyme B and induce agent C for pressing then for enzyme transmission and sending into puffing machine to get rough pastry.

Description

technical field [0001] The invention relates to pulping and papermaking technology, in particular to the pulping and papermaking technology of straw fiber, in particular to a pulping and papermaking method combining biological science, life science and mechanical manufacturing. Background technique [0002] The traditional paper-making straw pulp production method adopts alkaline chemical pulping. The treatment of straw pulp black liquor produced by this method is the focus of environmental protection work. The treatment technology of straw pulp black liquor has become a recognized problem in the world. The recognized treatment of wheat straw The best way to pulp black liquor is alkali recovery, but wheat straw pulp is the pulp with the most difficult alkali recovery technology due to disadvantages such as poor water filtration performance, high black liquor viscosity, and high silicon content. Especially for small or even medium-sized enterprises, due to the large investmen...

AI Technical Summary

Problems solved by technology

[0013] Disadvantages of applications 1 and 2: raw material processing is simple, lignin and cellulose separation effect is not good, tank or blasting pulper volume is limited by safety, single tank production capacity is low, production is discontinuous, and it is difficult to meet large-scale production Require

Patent application 5 is the simplest process technology, but due to the short soaking time of raw materials under normal temperature and pressure, the biochemical reaction is insufficient, which will affect the quality of straw pulp; pulp quality

The biochemical reaction time of patent 3 is relatively sufficient, and a pilot test has been carried out. The disadvantage is that the pollution of straw pulp is not completely solved. The inoculation and cultivation of the enzyme bacteria used requires a long time, large space, and high investment, resulting in high cost of the enzyme bacteria. Due to the high price of strains, it has brought difficulties to popularization and application

[0021] In short, these patented technologies are deficient in satisfying pulp quality, pollution control and industrial scale production at the same time.
