In 105 AD, Cai Lun of the Eastern Han Dynasty improved papermaking, which brought a major breakthrough to human civilization. The improvement of papermaking made people's lives and studies much more convenient, especially in the In modern times, various new paper types emerge in endlessly: newsprint, napkins, printing paper, draft paper, document paper, copy paper... Human life, work, and study are inseparable from paper, and the quality requirements of paper are very strict. Wood pulp needs to be extracted directly from wood and then made into various types of paper. Our Jianghe Paper industry makes high-grade copy paper. In the factory, we saw mountains of wood chips. I couldn’t help but think: This How many big trees did it take to cut down the pile? How many trees are these made of?
Papermaking is one of the four great inventions of human civilization in China, with a remarkable history of inventions. China is the first country in the world to weave silkworms. The ancients used silk fabrics that were made of floating wadding bodies to prepare multiple rough cocoons, leaving the remaining evil cocoons, silkworm cocoons and other diseases. After Drift Xu is completed, the tape gallery will have some residual lint left. When the number of flocculants floats, the remaining bamboo corridor accumulates into a thin layer of flocculent fibers after drying, which can be used for writing after being peeled off. A few products are made of floating flocculation in ancient books, on the bottom of the phone, or on the side of flocculation. This shows that the origin of China's papermaking history has a relationship with wadding. Yuan Xin and Cai Lun of the Eastern Han Dynasty improved papermaking in the first year. He used bark, hemp heads and rags, fishing nets and other plant materials, in pull-down, copy, baking paper and other manufacturing techniques that gave rise to modern paper. Since the invention of paper, the paper will be a new attitude for social and cultural life, gradually spreading to the land of China and later spreading throughout the world.
Paper is used for writing, printing, painting or packaging of fiber board products. Generally speaking, plant fibers are pulped by processing water suspensions, a combination of on-line interlacing, preliminary dehydration, and then drying through compression. China is the country that invented paper for the first time in the world. According to archaeological discoveries from the Western Han Dynasty (206 BC to 8 AD), China adopted flax fiber paper. Rough texture, as well as high cost and not universally rare. Since ancient times, the Chinese nation has known how to raise silkworms and reel silk. During the Qin and Han Dynasties, the inferior race, cotton cocoon craft was very popular. This method of treating cocoons is called the drift flocculation method, and the basic elements of operation include multiple beatings to break the silkworms' clothes. This technique later developed into a paper-making beating. In addition, the ancients used lime or plant ash water to degumming Sima. This technology also inspired the degumming of plant fibers in papermaking. This document was developed using these technologies.
Paper is an indispensable item in people's lives. People can't do without paper all the time, but we should try to save paper in our lives. If we continue, the 'green hills' will become 'bald mountains'. The mountain's natural environment will be seriously damaged, so we need to save paper: printing paper can be used on both sides, and the reverse side can be used as straw paper after the homework book is used up. The used paper can be recycled and reused to produce second-hand paper. Sub-paper, only in this way can the ecological environment be protected and the green mountains will never grow old!
