Abstract
The invention relates to a method for making paper by utilizing aquilaria sinensis branches and leaves, and the method is characterized by comprising the following steps of shattering and steaming braches and leaves of aquilaria sinensis; squeezing the steamed chips and chemically dipping the sqeezed chips; preheating the dipped materials and pulping the preheated materials to obtain unbleached raw stock; and papermaking, squeezing and drying after the blanching and pulping. The method mainly has the characteristics that the branches and leaves of the aquilaria sinensis are used for making paper, top-grade writing paper can be manufactured through the method, and the manufactured paper has the unique fragrance of the aquilaria sinensis and can bring peace to the mine. The branches and the leaves of the aquilria sinensis are used for manufacturing the paper, so that not only is the income of fragrance farmers increased, but also a great amount of papermaking lumber can be saved, the forest resource can be protected, less investment and fast effectiveness can be realized, and the economic benefit is remarkable.
Description
Technical field the present invention relates to field of papermaking, particularly relates to a kind of suspension culture of Aquilaria sinensis branch and leaf of utilizing as the papermaking process of raw material.
The background technology suspension culture of Aquilaria sinensis claims again buta-buta, the fragrant tree of tooth, it is the distinctive precious medicinal plant of China, in recent years, the medical value of agalloch eaglewood is paid attention to, at home extensively plantation of suspension culture of Aquilaria sinensis tree beginning, this seeds Edgeworthia chrysantha position is at trunk, and branch and leaf occupy more than half part of whole tree, people often do not abandon at the position of Edgeworthia chrysantha branch and leaf and trunk when obtaining trunk Edgeworthia chrysantha position, cause the loss of ample resources.
Summary of the invention
The purpose of this invention is to provide a kind of papermaking process, the method can utilize branch and the leaf of suspension culture of Aquilaria sinensis tree to be raw material papermaking.
Technical scheme
A kind of method of utilizing suspension culture of Aquilaria sinensis branch and leaf papermaking is characterized in that the method comprises following step:
1) branch of suspension culture of Aquilaria sinensis and leaf are pulverized and carried out decatize;
2) will carry out chemical impregnation after the extruding of the fragment after the decatize;
3) will flood good material preheater after pressurized refining obtain unbleached magma;
4) papermaking after the making beating, squeezing and oven dry after the bleaching.
Suspension culture of Aquilaria sinensis branch described in the described step 1) and leaf water vapour steaming time are in the 10min, and decompression gas steams under 0.9 atmospheric pressure.
Step 2) the chemical impregnation condition described in is: NaOH 2.4-2.7g/L, NaSO
32.9-3.1g/L, flood 20min under 90 ℃ of temperature.
Bleaching agent described in the step 4) is hydrogen peroxide, NaOH, sodium sulfite or magnesium sulfate.
The condition of bleaching is that bleaching liquid concentration is 10%, 60 ℃ of lower bleaching 2.5h.
Beneficial effect
1, the present invention is preferred reaction condition.Delicate fragrance is one of characteristic of suspension culture of Aquilaria sinensis maximum as suspension culture of Aquilaria sinensis, and how to keep fragrance in preparation process is a difficult problem, can keep delicate fragrance, meets again the paper requirement.The inventor is known the gentleer method of employing through great many of experiments, the employing in the step 1) decompression gas mode of steaming particularly, keep simultaneously in the 10min, benefit is not destroy the volatile materials of suspension culture of Aquilaria sinensis under the relatively-high temperature like this, high boiling especially material, so that the suspension culture of Aquilaria sinensis material obtains preliminary treatment, make things convenient for follow-up work to carry out simultaneously.NaOH 2.4-2.7g/L, NaSO
32.9-3.1g/L, flood 20min under 90 ℃ of temperature, the benefit of processing like this is can be in the gentle lignin part of processing wherein under the relative low alkalinity, is higher or lower than this alkaline range and all can works the mischief to fragrance component wherein.Bleaching agent described in the step 4) is hydrogen peroxide, NaOH, sodium sulfite or magnesium sulfate.The condition of bleaching is that bleaching liquid concentration is 10%, 60 ℃ of lower bleaching 2.5h.Under benign environment, paper is bleached, kept to greatest extent its delicate fragrance.Therefore select the bleaching liquid of low concentration, and the control time, show at great many of experiments, it is the most reasonable to process under this condition.
2, method main feature of the present invention is to utilize branch and the leaf of suspension culture of Aquilaria sinensis tree to carry out papermaking, can produce high-grade writing paper with the method, and paper can distribute the book suspension culture of Aquilaria sinensis and set distinctive delicate fragrance, with fixed attention pneumostatic.Utilize the branch of suspension culture of Aquilaria sinensis tree and the income that leaf papermaking both can increase Shannon, can save again the timber of a large amount of papermaking, protected the forest reserves, the small investment instant effect, economic benefit is obvious.
