Will paper ever disappear? 10, Will paper disappear?

I don't think so, everything has its own process of development, it is a product of the times, paper will not last forever, it will be replaced one day.

Summary. Hello dear, the content of the information you inquired is: the appearance of paper at the beginning is to facilitate the recording of text information, in ancient times, the ancestors mainly relied on the knotted rope chronicle, and later engraved words on the tortoiseshell animal bones, the so-called "oracle bone inscription".

After the bronze was produced, the inscription was engraved on the bronze, that is, "Jinwen" or "Zhong Dingwen". After that, the characters are written on the pieces made of bamboo and wood, which are called "bamboo and wood slips", and the wider and thicker bamboo and wood pieces are called "牍". At the same time, some are also written on the silk silk products.

Before the pre-Qin period, in addition to the above chronicles, inscriptions carved in stone were also found, such as the famous "Stone Drum Script". However, because silk was too expensive and bamboo was too bulky, it led to the invention of paper.

After the bronze was produced, the inscription was engraved on the bronze, that is, "Jinwen" or "Zhong Dingwen".

At the same time, some are also written on the silk silk products. Before the pre-Qin period, in addition to the above memorabilical materials, nuclear characters carved on stone were also found, such as the famous "Stone Drum Script".

However, because silk was too expensive and bamboo was too bulky, it led to the invention of paper.

Why do frogs jump?

Why is the sun round.

The invention of paper has advanced the progress of human civilization.

Because the hind limbs of the frog are detached from the tail, they are powerful underwater cave motor organs. Frogs are also going to land in the event. Because his hind limbs are strong and his forelimbs have no reed cracking force, jumping is the fastest way to exercise on land.

Of course, he can also crawl slowly on all four legs. Accompany the fibrillation to close.

All planets are circular, when the planet was first born, because of the high effect of gravity, plus the centripetal force that it rotates to lead Sun Sou, the closer to the poles, the smaller the centripetal force, so the less material at the poles, the closer to the equator, the greater the angular velocity, the greater the centripetal force, so there is more material here, so it looks like a circular Li Kaichi.

In ancient times, ancestors mainly relied on knotted rope chronicles, and later carved words on tortoiseshell animal bones, the so-called "oracle bone inscription". After the bronze was produced, the inscription was engraved on the bronze, that is, "Jinwen" or "Zhong Dingwen". After that, the characters are written on the pieces made of bamboo and wood, which are called "bamboo and wood slips", and the wider and thicker bamboo and wood pieces are called "牍".

At the same time, some are also written on the silk weaving products hunger. Before the pre-Qin period, in addition to the above-mentioned pre-collapse materials, characters carved in stone were also found, such as the famous "Stone Drum Script". However, due to the fact that the silk was too expensive and the bamboo chips were too bulky, it led to the invention of potato paper.

The main basis is the record of the Biography of Cai Lun in the Book of the Later Han Dynasty. Therefore, some later Chinese and foreign works are based on the honor of Cai Lun in the Eastern Han Dynasty as the inventor of paper, and the year 105 A.D., when he presented paper to Emperor Liu Zhao of the Han Dynasty, is the year of the birth of paper.

Before that, people used me to engrave words in bamboo slips, or write in silk, which was very inconvenient, and silk ** was very expensive.

Cai Lun (?) -121), the character Jingzhong, was a native of Guiyang County in the Eastern Han Dynasty. He summed up the previous papermaking experience, innovated the papermaking process, improved the papermaking technology, and made "Caihou paper".

Emperor Yongping of the Han Ming Dynasty entered the palace in the last year to give things, and in the second year of Zhang He (88 AD), Cai Lun was promoted to the middle attendant because of his meritorious service to the Queen Mother, and Cai Lun served as Shang Fangling as a respected Jiuqing. Cai Lun summed up the papermaking experience of people in the past and innovated the papermaking process, and finally made "Caihou paper". In the first year of Yuanxing (105 AD), the imperial court was reported, and Emperor He of Han ordered the promotion of his paper-making method.

Papermaking technology has promoted the spread of human culture and is a great contribution of the Chinese nation to world civilization. Paper is the crystallization of the long-term experience and wisdom of the ancient Chinese working people, and an outstanding invention in the history of human civilization.

Your idea is right The historical background of the Romance of the Three Kingdoms is the end of the Eastern Han Dynasty, and paper appeared in the Western Han Dynasty, but the paper at that time was rougher and different from what is used now.

The world's earliest paper appeared in the Western Han Dynasty in China. The paper from the early Western Han Dynasty (206 B.C., 23 A.D.) unearthed from the Fangmatan Han Tomb in Tianshui, Gansu Province, China, is the earliest paper that has been discovered. In addition, ancient paper from the Western Han Dynasty has been unearthed in places such as Lop Nur in Xinjiang and Duba Bridge in Xi'an.

But these papers are relatively coarse, and the raw materials are hemp or silk wool. Extended Information The world's earliest paper appeared in the Western Han Dynasty in China. According to archaeological discoveries, during the Western Han Dynasty, China already had hemp fiber paper.

However, its texture is coarse, and the quantity is small, the cost is high, and it is not popular. In 105 AD, the eunuch Cai Lun summarized the Taoism of the Western Han Dynasty'Papermaking technology and to improve, created a bark, rags, hemp, fish nets as raw materials, and to dip, pound, copy a set of technology, to create a special to reach the practical level of writing plant fiber paper, called "Caihou paper". Since then, paper has gradually replaced bamboo and wood tubes and silk as the main writing materials.

The raw materials of papermaking are mainly plant fibers, and in addition to the three main components of cellulose, hemicellulose and lignin, there are other components with less content, such as resin, ash, etc., in addition to auxiliary components such as sodium sulfate. In addition to plant fibers, different fillers need to be added to the paper according to different paper materials.

The production principle of thermal paper is to coat the ordinary paper base with particulate powder, the composition is colorless dye phenol or other acidic substances, separated by a film, under heating conditions, the film melts, and the powder is mixed to develop a color. The handwriting on the thermal paper is unstable and easy to fade, making the content of the document illegible.

When the thermal paper is placed in an environment above 70 degrees, the thermal coating begins to change color. The reason for its discoloration also starts with its composition.

There are two main types of heat-sensitive components in thermal paper coatings: one is colorless dyes or hidden dyes; The other is a chromogenic agent. This type of thermal paper is also known as two-component chemical thermal recording paper.
