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 rea

Embodiment 1

[0052] The forage is wheat straw. Spread the wheat straw in the yard. The thickness of the wheat straw is roughly uniform. After rolling, turning, and rolling again with a tractor, use a flat vibrating screen to remove dust and other sundries, and then use a grass cutter to cut the wheat straw into 2- The 3 cm long short joints were sampled to test the content of moisture, cellulose, hemicellulose and lignin in wheat straw. And weigh 100 kilograms of forage, put it into a kneader with a volume of 1000 liters, start the kneader, spray H2O2 aqueous solution A first, or an aqueous solution of organic solvents such as oxalic acid, acetone or methanol, stir evenly, and then disperse the cellulose After the enzyme B is stirred evenly, disperse and sprinkle in the inducing melt-promoting agent C until the forage is co-kneaded and infiltrated in the kneader for 30-40 minutes, wherein the weight ratio of the absolute dry weight of the forage to the H2O2 aqueous solution is 100:19±1, and...

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...
