Description
Technical Field
The invention relates to the technical field of papermaking, in particular to a paper mulberry production method.
Background
Paper is an indispensable substance in many fields of social civilization progress, daily life, cultural education and the like, and currently, more than 500 paper types are known. Paper is one of four inventions in China, and has reached 1800 years since Cai Lun paper making technology in east China, but the materials used for paper making are basically unchanged. However, in order to meet the increasing demand, chemical materials are adopted, so that the production capacity is increased, and a large amount of pollution is generated. According to statistics, more than 400kg of strong alkali, 150-200 tons of water, 50kg of bleaching powder, nitrite and the like are consumed per ton of paper produced. Serious pollution is caused to the environment, BOD (biochemical oxygen content) and SS (suspended solids) in the papermaking wastewater are high, and the papermaking wastewater contains a large amount of chemical components, the pollutant is high, and the BOD is as high as 5000-9000 ml/L. In the production process of the Xuan paper which is one of the "four treasures of the study" to the treasures of China, a large amount of harmful substances are generated as in the conventional papermaking process, and the production period is longer than one year. Jingxian County Xuan paper is loved by vast calligraphy lovers, along with the development of culture and education industry, the requirement on the Xuan paper is also larger and larger, along with the increase of the output of the Xuan paper in the production process, the excreted toxic and harmful substances are more and more, the traditional raw material sandalwood for producing the Xuan paper is also larger and larger in dosage, the Santalian tree produced by Jingxian County is also inapplicable, the other main raw material for producing the Xuan paper is sand-field straw, the special indica rice growing in the sand soil of Anhui Jingxian County is long in straw, the fiber content is high, the knots are less, and the produced paper is excellent, but the straw can be imported into the Xuan paper production process only Jingxian County, and the sand-field straw can not meet the requirement for producing the Xuan paper due to the continuous increase of Jingxian County Xuan paper output. Therefore, a paper mulberry paper production method is needed to be designed to solve the problems that the chemical material consumption in the existing papermaking is large, the environment is polluted, and the consumption of the existing raw materials is large in the rice paper manufacturing.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide a paper mulberry production method.

The implementation steps of the method are as follows:
1. Removing the iron sand skin: the method uses iron small-body-diameter iron sand with hardness larger than that of the bark of the paper mulberry stem to roll and strike the paper mulberry stem in a roller, and the bark (cuticle and dead skin) of the paper mulberry stem is removed by friction. The grain size of the iron sand is 0.1-1.5cm, and the length of the broussonetia papyrifera stems is 0.15-15 cm. During rolling, the paper mulberry is washed by clean water until the phloem of the paper mulberry stem is fully exposed to the standard.

2. Enzymolysis treatment
After the paper mulberry bark is subjected to the above treatment, the paper mulberry bark is subjected to enzymolysis treatment.
This method has not been applied in conventional papermaking.
(1) Selecting strains: white rot fungi in actinomycetes are adopted as the strain for making.
The enzyme-producing bacteria which degrade lignin well are many, and the enzyme-producing bacteria can produce laccase, brown rot enzyme, white rot fungus of cellulose, brown rot fungus, soft rot fungus and the like. The Huang Baoyuan Phanerochaete in white rot fungi is the most studied lignin degrading enzyme, and the enzyme production condition is related to a carbon source, like white rot fungus and trametes hirsutum.
The degradation of the actinomycetes to lignin is characterized in that the actinomycetes are water-soluble, and the actinomycetes penetrate through insoluble matrixes such as lignocellulose and the like, so that the actinomycetes participate in the decomposition and decomposition of the initial decay of organic matters under the neutral or slightly alkaline condition, and the lignin of the forest fungi belonging to the streptomyces can be reduced by 20%. Therefore, white rot fungi in the selected special actinomycetes and the degradation process thereof are selected.
(2) The paper mulberry bark treated by the iron sand is inactivated for 15 minutes at the temperature of 100 ℃ so as to inactivate microorganisms in the paper mulberry bark and facilitate the growth and propagation of white rot fungi.
(3) Cooling the inactivated paper mulberry bark in the step (2) to about 40 ℃, and mixing with white rot fungi. The streptomycete in the actinomycetes is actinomycetes bred after the selected strain is selected from the actinomycetes, and belongs to aerophilic bacteria. In the process of growing and oxidizing organic matters or organic matters in an aerobic environment, oxygen molecules are taken as final electric acceptors to perform aerobic respiration, but no mitochondria exists, and the aerobic bacteria consume carbon hydrogen in lignin, and carbon dioxide and water are generated without pollution to the environment.
Selection and application amount of actinomycetes: lignin degradation of white rot fungi can selectively decompose lignin in plant straws, so that biological pulping is possible. The biological pulping is to directly utilize microorganism to degrade lignin in the fiber-containing raw material, and separate fibers to form paper pulp, and the seeding method not only saves energy consumption, but also improves the physical properties of paper, reduces or avoids pollution and protects environment.
The applicable amount of the white rot fungi is 1:10000, and the concentration can reduce the manufacturing amount of the white rot fungi through experiments, and can not cause uneven influence on the activity due to too few parts of strains.
The specific method comprises the following steps:
and (3) measuring the total number of white rot fungi active bacteria in the bacterial liquid, uniformly spraying the liquid mixture on paper mulberry bark subjected to iron sand impact delignification, and adding clear water, wherein the time period is 7-10 days under the condition of 30-45 ℃ exceeding the paper mulberry bark serving as a standard.
The other raw material in Jingxian County Xuan paper production raw material is Jingxian County sand field straw, the grain produced by the rice is not high, but the straw is longer than the straw of common rice, and the fiber content in the fiber straw is higher than that of the rice straw. The indica rice in the rice is detected, the straw is higher than other rice, the nodules are less, the ash is less, the lignin is lower than other rice straw. The traditional processing technology of the long-grained nonglutinous rice straw, which is not easy to rot and bleach, comprises the processes of grass selection, single embryo processing, grass-removing processing, pulp-removing processing and the like, is an important link in the production of rice paper, and can be completed after one year through eighteen processes of soaking, distilling, bleaching, pulping water, fishing, gluing, pasting, drying and the like.
The traditional paper making mode is long in duration, complicated in working procedure, high in price and capable of greatly influencing the development of cultural industry to a certain extent according to market demands, the indica rice straw in sand fields grows about 10cm of common rice, the common rice is about 85-100cm in height, the rice is about 90-120cm in height, the fiber content is 31.69%, the protein is 5.9% and the lignin is 25.22%.
The rice straw components of various rice growing areas (including Heilongjiang, shandong, jiangsu, guangdong, guangxi and Fujian) in China are investigated to be approximately the same, the fiber in the indica rice straw is shorter, and the paper mulberry bark fiber with longer fiber is mutually complemented, so that the process requirements of softness, smoothness, ink wetting effect and the like of paper are better, and the detection proves that the quality of the rice paper prepared by adding the raw materials of the indica rice straw produced by the outside of the jingjingjiu is not different from that of the rice paper produced by the traditional process.
3. Process for preparing long-grained nonglutinous rice
(1) Cleaning indica rice straw, removing impurities, naturally stacking for 8-24 times under wet condition, aging, naturally fermenting, and discarding yellow water generated in soaking process.
(2) The indica rice straw is taken and cooked for 15 minutes at the temperature of 100 ℃ for inactivation, so that various bacteria in the indica rice straw are inactivated, and the growth of white rot fungi is facilitated.
(3) White rot fungi with the activity of more than 95 percent are taken by the weight of 1/10000 of the indica rice straw, and the white rot fungi are uniformly sprayed on the indica rice straw cooled to 30-45 ℃.
(4) Preserving heat at 30-45deg.C for 5-7 days, and turning over the layers to exchange layers. The water level of the diffuse foam exceeds that of indica rice straw.
(5) The indica rice straw is washed to be white by clean water, the main components in the clean water comprise dissolved oxygen or CO 2, lignin fibers and the like, and most of CO 2, O 2 and the like generated in the decomposition process are selected in the atmosphere, so that the environment is not polluted.
The water is weakly acidic or neutral, can be used as near neutral natural water under natural conditions of 21-30 days in a pool, and is directly used for filling or draining into natural water system, and has no pollution to environment and no toxicity or pollution to environment due to lignin.
The weight loss of indica rice straw treated by white rot fungi is 25-35%, and the weight loss is characterized in that the essential components are water quality element, mineral substances and other impurities.
The force used for kneading in the process of cleaning the indica rice straw is light to prevent fiber loss.
Before the water is discharged, the fiber components in the water are filtered through a 80-mesh sieve, so that the fiber loss is prevented, and the fiber in the water is reduced, so that the water is kept in an environment-friendly state.
The indica rice straw treated by the method has no original shape. White bundle shape, which can be mixed with paper mulberry bark treated by white rot fungi in a ratio of 8:3 (paper mulberry bark 8, indica rice straw 3), and the ratio is special clean leather rice paper; the formula is that 7 parts of paper mulberry bark treated by white rot fungi is mixed with 3 parts of indica rice straw treated by white rot fungi to obtain a formula of clean leather Xuan paper; 6 parts of paper mulberry bark treated by white rot fungi and 4 parts of indica rice straw treated by white rot fungi are mixed to obtain the component formula of cotton material rice paper.
The three papers are different:
Tension: special skin-cleaning cotton material
Anti-wrinkle: special skin-cleaning cotton material
Whiteness: special skin-cleaning = cotton material
Tear resistance: special skin-cleaning cotton material
Simulated paper life span: special skin-cleaning = cotton material
The length of the fiber of the drawn paper is required to be 1-3cm, the drawn paper is dried until the moisture is less than or equal to 10 percent for standby, the drawn paper is recovered by clear water when in use, and the pulping process is the same as that described above.
The fiber length requirement is that the fiber length in Xuan paper has a great influence on paper process indexes, preferably 1.7-3.7mm, and the paper mulberry bark fiber length is in the distribution range of 19.6mm (average 9.37 mm), so that the paper fiber length is uniform, and the paper fiber is passed through a milling machine. The principle is that paper mulberry fibers are made into lengths of 1.7-3.7mm in a high-speed shearing mode when the paper mulberry fibers pass through the machine.
When the whiteness of the finished product can not meet the process requirement due to the change of water quality, air temperature and the like, titanium dioxide can be added into the paper pulp. Titanium dioxide is the whitest of the known materials. Per gram of rutile titanium dioxide, 450cm 2 of surface area can be whitened.
The fineness of the upper-fixed titanium dioxide reaches 601 mesh or less, and has no influence on the smoothness, the smoothness and the like of paper. Titanium dioxide is a strong oxidant, is nontoxic and odorless, is white, has better diffusivity in water, is a photocatalyst, and has the effects of purifying air and resisting bacteria and deodorizing. When the paper pulp is added, the ratio of the paper pulp to the paper pulp is 0.5/100, and the satisfactory effect can be achieved.
The titanium dioxide is added uniformly when the paper mulberry bark and the indica rice straw fiber pass through a milling machine, and the titanium dioxide is distributed more uniformly after passing through the milling machine.
The paper made by the process has no difference with rice paper made of Pterocarpus Indicus bark and Jingxian County sand field straw in various process indexes, but has longer life span, and more excellent strength, whiteness, ink-wetting degree and the like than the traditional rice paper.
