    Pulping. Process Pulping is the first step in papermaking, and there are generally three methods to convert wood into pulp, including mechanical pulping, chemical pulping and semi-chemical pulping.

    2.Modulation. Process The modulation of paper stock is another key point of papermaking, and the strength, tone, printability, and length of paper shelf life after the paper is completed are directly related to it.

    The common modulation process can be roughly divided into the following three steps: aLoose slurry b

    Pulp CGluing and filling.

    3.Copying. Process The main work of the papermaking department is to make the thin paper stock evenly interwoven and dehydrated, and then dry, calender, roll paper, cut, select, and package, so the common process is as follows

    a.Screening of paper stock The prepared paper stock is diluted to a lower concentration, and the impurities and undissociated fiber bundles are screened out again with the help of screening equipment to maintain quality and protect the equipment. b.

    The mesh part makes the paper stock flow out of the head box on the circulating copper wire mesh or plastic mesh and evenly distribute and interweave. c.The pressing part leads the wet paper removed from the mesh surface to the two rollers with a woolen cloth, and the wet paper is further dehydrated by the pressing of the roller and the water absorption of the wool cloth, and the paper is tighter, so as to improve the paper surface and increase the strength.

    d.Dryer Because the wet paper after pressing, its moisture content is still as high as 52 70%, at this time can no longer use mechanical force to press out the water, so let the wet paper go through many internal heat vapor cylinder surface to dry the paper. e roll paper by a paper reel to roll the paper web into a paper roll f

    Cutting and sorting Packaging: Take a number of paper rolls that have been rolled into a cylinder in front of them, cut them into sheets of paper with a paper cutter, and then remove the damaged or stained paper by manual or mechanical selection, and finally wrap every 500 sheets into a pack (usually called a ream).

    Synopsis of this paragraph.

    The play tells the story of the party branch of a mountain village, leading the villagers to get rid of poverty and become well-off. The trees are towering.

    Zhang Baogen, a young man from Lizhai Village, got rich by opening the "Liwang Company", although he also did some good things for the village, but he was always a little wealthy. He failed in the annual competition for the "Pear King" in the village-wide mass election, and he was unconvinced, mistakenly thinking that he was caused by people outside the party, so he asked the village party secretary and the future mother-in-law Aunt Dashu to join the party, thinking that this was a matter of "pinching the snail with three fingers - taking it steadily". Unexpectedly, Aunt Dashu asked him to study the party constitution, wait for the branch committee to discuss and decide, and undergo the test of the organization.

    Baogen disagreed, especially when he wanted to join the party as soon as possible to realize his desire to serve as deputy mayor, he was even more impatient. The plot is thus in a conflict. The image of Aunt Da Shu, the party branch secretary who does not look at the limelight, is not tempted by money, and has the fundamental interests of the people in her heart, stands on the stage like a towering tree.

    This drama eulogizes the story of the grassroots workers of the rural party in the new period after the reform and opening up to seek the interests of the people wholeheartedly, so that people not only feel the tremendous changes brought by the reform and opening up to rural life, but also truly see the touching deeds of ordinary rural party members represented by the party secretary Aunt Dashu leading the masses to become well-off, and the ideological and artistic aspects have reached a perfect unity. In 1999, he won the provincial "Five Ones" project award. In 2000, he won the second prize of performance and four excellence awards at the 6th Provincial Art Festival.

    In 2001, he was invited to participate in the 6th China "Yingshanhong" Theater Festival, and won the first prize for playwriting, directing and composition, and the first prize for actor performance. In 2002, Jin Jing reported the performance of the modern drama "Big Trees Towering to the Sky", which was premiered by Suzhou Bangzi Theater Troupe in 1999.

    Made from plant fibers.

    Paper, made of plant fibers, is a non-woven fabric that can be folded arbitrarily for writing.

    The earliest paper was 2,200 years ago, and there was paper in the early Western Han Dynasty, but it was still very rough and not widely used. In 105 AD, after the improvement of Cai Lun in the Eastern Han Dynasty, it is considered to be the originator of modern papermaking. ("Papyrus" is not the current concept of "paper", it is a writing medium made of papyrus this plant by a certain treatment, and the papermaking technology invented in China breaks the original arrangement of plant fibers, making it irregularly cross-arranged, so that the finished product can be called "paper".)

    During the Yin Shang period of China, writing was invented and oracle bones began to be used as writing materials, and bamboo and wood chips and silk were discovered and used as writing materials in the Spring and Autumn Period. However, because the silk was too expensive and the bamboo was too bulky, paper was produced. One of the four great inventions of ancient China, papermaking, along with the compass, gunpowder, and printing, provided the material and technological basis for the prosperity of ancient Chinese culture.

    The invention of paper ended the complicated history of ancient slips and greatly promoted the spread and development of culture.

    Generally, the production of printed paper is divided into two basic processes: pulp and paper. Pulping is to use mechanical methods, chemical methods or a combination of the two methods to dissociate plant fiber raw materials into colored pulp or bleached pulp. The pulp fibers suspended in water are then combined into paper sheets that meet various requirements through various processes.

    The details are as follows: 1. Paper mills generally need to store enough raw materials for 4 to 6 months, so that the raw materials can be naturally fermented in storage to facilitate pulping and ensure the continuous production of paper mills.

    2. Raw materials such as reeds, wheat straw and wood are cut into flakes (for the production of chemical pulp) or wood breaks (for the production of grinding wood pulp) through the preparation section, and then small pieces of raw materials are put into the digester with chemical liquid, and the raw materials are steamed with steam to be boiled into pulp, or the wood breaks are sent to the grinder to be ground into pulp, and they can also be ground into pulp after a certain degree of cooking.

    3. Then wash the pulp with a large amount of water, and remove the coarse flakes, knots, stones and sand in the pulp through screening and purification. Then, according to the requirements of the paper grade, the pulp is bleached to the required whiteness with bleach, and then the pulping equipment is used to pulp.

    Fourth, add various auxiliary materials such as fillers, rubber materials, sizing agents and other accessories to improve the performance of paper in the pulp, purify and screen again, and finally send them to the paper machine to go through water filtration, pressing and dehydration, drying in the dryer, calendering and winding, and slitting and rewinding or cutting to produce web paper and flat paper.

    There are few historical records about the ancient Chinese paper-making method, but in terms of the paper-making process and its principle, there has not been much substantial change in the 2,000 years since its invention. To sum up, the following steps can be summarized:

    1. It is to soak the felled plants, such as hemp plants, with water, peel their skins, then chop them with a knife, put them in a pot and boil them, and then soak them and step on them after they are cooled, and stir them with sticks to break and thin their fibers.

    2. It is mixed with auxiliary materials to make pulp.

    3. It is to use a papermaking device (bamboo curtain and the like) to copy and dry, which can be made into paper.
