Problems solved by technology

In the Chinese patent ZL93108071.1, a "method for making banknote paper, etc. from banana fiber" is disclosed, which is complicated in process and not practicable
Because the banana tree cannot be dried in the sun at all, and the banana tree has rotted before it is dried in the sun. It is impossible to be used in the production of banknote paper; and the drying cost is high, and the drying cost per ton needs to be more than 1,000 yuan; third, the caustic soda and other additives added in the process are serious to the environment; finally, the method still has production long cycle defect

Embodiment 1

[0035] 1 Raw materials: Take 15-20 tons of fresh banana trees, without drying or sun-drying, the whole plant can be processed directly. In the banana orchard, the banana tree can be directly squeezed out about 70% of the water through a press machine, which is beneficial to reduce the burden of transportation and storage. Every 15-20 tons of plastic fresh banana products can produce 1 ton of dry pulp, and the following percentages are based on dry pulp as the total percentage.

[0036] 2 Chopping and pulping to remove impurities: Cut the squeezed banana tree into 3-5 cm long pieces with a cutting machine, then send them into a beater, beat them into a slurry of 20-25°SR, and then send them into the flowing water sink Sand ditch, carry out sedimentation and impurity removal treatment.

[0037] 3 Concentrating by filtration: the above-mentioned feed liquid after removing impurities is passed through an inclined sieve to concentrate by filtration to a concentration of 30%.

Abstract

A process for preparing paper pulp from banana tree and making paper includes such steps as cutting banana three and crushing, beating, concentrating, diluting by adding water, adding hydrogen peroxide and ammonia water, digestion under normal pressure, heating to 95-98 deg.C, bleaching, degumming by adding acetic acid, diluting by adding water, grinding into pulp, and making paper.

Description

(1) Technical field: [0001] The invention relates to a paper pulp made from banana trees and a production process thereof. (two) background technology: [0002] As we all know, in the case of the continuous reduction of forest resources in our country, a paper mill destroys dozens of acres of forest a day, thus seriously destroying the ecological balance and causing serious water and soil loss. In order to protect forest resources, the state has announced to shut down all paper mills that use trees as raw materials, and the paper industry that uses other plant fibers as raw materials has serious pollution problems, and the price of imported pulp continues to rise. Therefore, paper raw materials and Pollution has become two major insurmountable problems in today's paper industry, but people's daily life is inseparable from paper, so how to solve the problem of paper raw materials and pollution has become the key to the paper industry. In Chinese patent ZL93108071.1, a "metho...
