Embodiment 1

[0017] Select 3 tons of fresh banana stalks and cut them into small pieces of 4×6cm through a slicer, and then use a high-concentration hydraulic refiner for ordinary papermaking to grind. The organic enzyme is sprayed on the material at the entrance of the refiner through a metering pump, and 6kg of organic enzyme solution is used for each ton of material by weight. On the material at the entrance of the pulp machine, the temperature of the material in the refiner is controlled at 60-70°C. Under the action of enzyme and temperature, the material is ground to cause molecular fission of the fiber, and the fine pulp discharged after grinding passes through the pulp tank. Stir and tumble continuously with the propeller for 20-30 minutes, then filter through a conventional 60-mesh inclined sieve to filter out ash, hemicellulose and pectin that are not conducive to papermaking, and then conduct a medium-concentration grinding Just can obtain 2.1 tons (wet weight) of unbleached orig...

Embodiment 2

[0019] 5 tons of fresh corn stalks are selected and cut into small pieces with a length of 4-6 cm by a slicer, and then grinded with a high-concentration hydraulic refiner for ordinary papermaking. The organic enzyme is sprayed on the material at the entrance of the refiner through a metering pump, and 10kg of organic enzyme solution is used for each ton of material by weight. On the material at the entrance of the pulp machine, the temperature of the material in the refiner is controlled at 60-70°C. Under the action of enzyme and temperature, the material is ground to cause molecular fission of the fiber, and the fine pulp discharged after grinding passes through the pulp tank. Stir and tumble continuously with the propeller for 20-30 minutes, then filter through a conventional 60-mesh inclined sieve to filter out ash, hemicellulose, pectin, etc. Just can obtain 3 tons (wet weight) of unbleached original pulp that is 27~30 degree of knocking degree for papermaking.

Embodiment 3

[0021] Use 7 tons of dry straw to cut into small pieces with a length of 4-6 cm each through a slicer, and then use a high-concentration hydraulic refiner for ordinary papermaking to grind. The organic enzyme is sprayed on the material at the entrance of the refiner through a metering pump, and 14kg of organic enzyme solution is used for each ton of material by weight. On the material at the entrance of the pulp machine, the temperature of the material in the refiner is controlled at 60-70°C. Under the action of enzyme and temperature, the material is ground to cause molecular fission of the fiber, and the fine pulp discharged after grinding passes through the pulp tank. Stir and tumble continuously with the propeller for 20-30 minutes, then filter through a conventional 60-mesh inclined sieve to filter out ash, hemicellulose and pectin that are not conducive to papermaking, and then conduct a medium-concentration grinding Just can obtain 4.9 tons (wet weight) of unbleached or...

Abstract

The invention discloses a method for preparing virgin pulp for papermaking by utilizing an organic enzyme to carry out enzyme treatment on herbaceous plants, which comprises the following steps: using the herbaceous plants as the raw materials; spraying the organic enzyme on the materials; carrying out grinding by a high concentration hydraulic grinder; stirring and rolling over the ground virgin pulp in a pulp pool to obtain soft crude fibers; and after filtering the soft crude fibers by an inclined screen, feeding the obtained product into an intermediate concentration hydraulic grinder to grind to obtain the virgin pulp for papermaking, which has the beating degree of 27 to 30 degrees. The invention provides a papermaking process, which implements the digestion-free process of preparing the pulp by the herbaceous plants and has no emission capable of polluting the environment; the yield of the pulp is higher than 20 percent than that of the pulp prepared by a conventional grinding process; and the beating degree is improved by 2 to 3 degrees.

Description

technical field [0001] The invention relates to a method for preparing raw pulp for papermaking by enzymaticizing herbs with organic enzymes. Background technique [0002] As we all know, the raw materials of papermaking are divided into wood and non-wood. Since the progress of human life and civilization cannot do without paper, paper products have become one of the indispensable items in human life. According to statistics from the forestry department, the growth cycle of each cubic meter of wood takes 15 years. If wood continues to be cut down for papermaking, it will inevitably affect water and soil conservation and destroy the ecology of nature. [0003] Harmonious survival is inseparable from the gift of nature. In addition to forest wood papermaking raw materials, my country also has many non-wood papermaking raw materials, such as straw, corn stalks, and wheat straw. It's just that we don't have enough science and technology and means to make full use of it. For ex...
