In the original time and space, the world's best paper-making technology, the highest paper output is Mingda 6. This is not to say that there is no paper-making technology in other regions, in fact, the earliest paper-making technology is the papyrus technology of Egypt.

However, compared with the papermaking technology of Mingda 6, Egypt's papyrus papermaking technology is not only complicated, but also has a high production cost, so when Mingda 6's papermaking technology is transmitted to Egypt, it is easy to defeat their technology.

Of course, there are also various papermaking technologies in other regions, but they are really slag and not worth mentioning.

In the middle of the 19th century, the papermaking technology of the West was able to develop by leaps and bounds, and in turn it was able to defeat the papermaking technology of the Ming University 6, which was wrong, and it was the papermaking technology of the former Qing Dynasty 6......

In the original time and space, in 1839, the German P. Piert used a spherical digester to cook rags under a certain pressure to make pulp. In this way, the Germans completed the improvement of the equipment first.

In 1851, the Englishman H. Burgers understood the technology of using caustic soda as a medicine to cook wood pulp. This in turn provides new ideas for other Westerners' papermaking technology.

Finally, it was not until 1866 that the American B.C. Tillmanming used the acid sulfite method to cook wood pulp, which expanded the pulp raw material from herbaceous plants to wood, and the production of paper increased exponentially.

Until the late 19th century, acid sulfite pulping played an important role due to its low production cost and light color of pulp.

So far, the papermaking technology of the West has completely defeated the former Qing Dynasty 6.

When the people of Hantang Group analyzed the exhibition of Western chemical technology in the original time and space, they keenly realized that the exhibition of Westerners in chemical technology made full use of the achievements brought by the salt chemical industry, thus forming a sustainable exhibition of the rising road.

Of course, their unfolding is too slow, and they can be used as a unit of calculation in a hundred years, but what about the former Qing Dynasty 6? Thousands of years, right? Is there an exhibition of papermaking technology?

On that large 6, since the Jin Dynasty, they expanded the raw materials for papermaking to include straw, mulberry peel and young bamboo, and used lime and plant ash (the main component is potassium carbonate) to pickle or cook to make pulp, which may be the earliest chemical pulping.

However, thousands of years have passed, and their children and grandchildren have not been able to pass this hurdle, and they have not been able to get the raw materials into the wood. That's the right way, the quality and quantity of paper can only be guaranteed by it!

Why? There is really no one to hack the descendants of the big 6, but they themselves have closed the door to further development for themselves!

The best, the most, the cheapest sulfate, caustic soda, soda ash, are all in salt!

But their rulers from generation to generation have shouted that it is forbidden to sell salt without permission, and that it is up to me to sell it!

And they will say in a loud voice, no way, the state wants taxes. But is there really no other way? No one is looking for it, and of course there is no way.

The salt tax is too lucrative, too stable, too easy to get......

Anyway, I don't know how many people have scolded me for water.

At the estuary base, technician Hou Zhiben decided to go directly to acid sulfite pulping, of course, he knew that this method was a waste of chemical raw materials and was highly polluting.

However, its production process is simple, the paper produced is lighter in color, and can be used as papermaking without bleaching steps, with higher whiteness and softer paper. The bleaching process is saved, that is, manpower is saved.

Although the paper produced by this process has weak physical properties, it is okay to use it carefully.

In fact, there are two other methods, which are briefly introduced here.

The paper produced by alkaline pulp is softer and has higher opacity, and the physical properties of the paper are stronger. However, alkali has other more important needs for the people of Hantang Group, and it cannot meet the demand for papermaking now. The Hantang Group can only wait for later.

Kraft pulp is the more common method in that side of the world. Because it is distilled with Na2S, the evaporation is easy and the effect is good, and the paper made of this pulp has better strength, good softness, and good durability, and the whiteness of the paper can be greatly improved after bleaching.

However, it has relatively high requirements for equipment and the process is quite complex.

At the beginning, Li Ziqiang almost jumped up when he saw the equipment needed for kraft pulp, and said: "This is more than the equipment of my machine factory, no, no, it's not worth it just for a few pieces of broken paper, I absolutely agree with the original mention of the cooking tank equipment, and I don't object." ”

The cooking tank equipment is the basic equipment for the chemical pulping process. According to the process, it is divided into two categories: batch cooking tank equipment and continuous cooking tank equipment.

Stationary vertical cooker equipment. The equipment is relatively simple, can be easily controlled temperature and pressure, easy to operate and maintain, it is originally suitable for small and medium-sized pulp mills in the world. Of course, there are a lot of problems, it is uneven in the steam load for heating, it is difficult to recover waste heat, and the uniformity of the slurry is poor.

Continuous cooking tank equipment, the people of Hantang Group directly gave up it...... No matter how high the quality of its output is, it needs too many auxiliary equipment.

But with such a simple equipment, Li Ziqiang still wanted to suppress it, and at the same time, he insisted on making paper in the later stage, so when Sun De took out the equipment table needed for the production of sulfate pulp, he was immediately honest.

The raw materials required for the paper mill in the estuary are supplied by the estuary wood base.

The people of the Han Tang Group hired the natives to peel the wood and split it into wooden blocks, so that there was no miscellaneous things in the raw materials, so that the raw materials were relatively clean, and the size and specifications were more neat and uniform, which was conducive to the smooth progress of the physical and chemical reactions in the next cooking process.

When Hou Zhiben technician collects papermaking raw materials in the papermaking raw material yard, he carefully inspects each time and tries to stack the same kind of raw materials together.

Sun Qiang, a part-time chef who always claims to be drunk and not messy, said to him: "Lao Hou, can you use such raw materials to make wood pulp?" If this is in that world, this factory must not be yellow immediately......"

"Ah, you know something about the paper industry? Aren't you whole oil? ”

"What kind of oil, I am a major in oil extraction, and I have a college certificate recognized by the state...... Once I went to a small toilet paper and tablepaper factory, my God, the rotten paper, the workshop was full of dust, and flies were flying everywhere...... Later, I didn't dare to use the paper in the restaurant anymore...... It's too dirty to wipe your butt! ”

"There's no way, the cost of the world over there is king! However, some genuine products can still be trusted, such as some wood pulp content greater than 60%, straw pulp is OK, but the wrinkles are too big, black, and they don't sell well...... It is all marked on the packaging, if it is true. ”

"I can't believe it."

"Believe it or not...... I can't go back, and I don't want to go back! ”

"Haha, Lao Hou, you see I forgot about this stubble...... We're 100% wood pulp, and I'm still in charge of the dry hair of the world over there! ”

The basic process of the transformation of raw materials into chemical pulp. These sections and an appropriate amount of chemical agents are loaded into the digester, and the temperature, pressure, time and liquid composition of the medicine are controlled, so that the liquid medicine penetrates into the raw materials and reacts with the lignin biochemical reaction in the raw materials, so that the single fiber is loosely separated into pulp, and the pulp formed by cooking is called brown pulp.

In most cases, the primary wall of fibroblasts is also destroyed, and in the case of a strong cooking reaction, a part of lignin is dissolved from the secondary wall of fiber, and other carbohydrates, resins, inorganic salts and other components are also partially removed, so the pulp prepared by chemical method usually has a high cellulose content. The level of cellulose also often determines the quality of the paper.

This appropriate amount of chemical agent has to be independently prepared by Hou Zhiben technician according to different raw materials and conditions. No chemistry is the same every time.

But the point is that he has never worked in this industry before, although he does not understand it at all, the information is all now, just check it, and understand the basic reaction process, but he has no experience, so he can only debug one type at a time, and carefully make records in order to make comparisons...... Let's practice to know the truth, and explore it a little bit.

The method used by Hou Zhiben technician is simple to say, and the chemicals used will also be produced by Hantang Group, with Na2SO3 and NetA2NetahCO3 as buffers.

However, their various proportions, temperatures, pressures and characteristics of raw materials are different, and they need to be trial-produced little by little. Fortunately, this chemical pulping method can process 65-85% wood pulp fiber. In this way, the paper made has a greater flexibility in the use space and more types.

It is precisely because of this continuous exploration that the characteristics of each paper produced cannot be the same.

So the traversers in other places are very strange, the paper sent by the estuary paper mill has a lot of varieties, and they are not afraid of trouble, just one or two varieties are fine. We don't pick.

Those who understood the details smiled silently.

If you really need high-grade writing paper, Hantang Group can also produce it, so there will be a multi-stage drift, which puts forward new requirements for the process, and also puts forward new requirements for the salt chemical industry, such as hypochlorite and liquid chlorine......

However, of course, the Hantang Group would not make such a painful request in this time and space, it would be good to have it.

Other precipitation, wood pulp blending, papermaking, filling, flattening, and glazing are all very simple things, and the technical content is not high.

In June, after the Pan family labor company organized by Zhou Fu arrived in the city of Geranza, the estuary base hired a few Ming laborers from there, and after teaching them for a while, they handed over these later jobs to them.

Of course, that's for later.

Regarding the printing equipment, Hantang Group did not bring it at all. In Li Ziqiang's words, what does this bring? I can give you the equipment before the sixties of the 2O century...... Later, the chip technology is a chemical problem, and you go to Sun De, it has nothing to do with our machining.

Therefore, the people of the Hantang Group can only use ordinary printers to play first, but fortunately, there are not many students, only more than 100 people, and each person is nothing. It was all planned, and it wasn't even met at that time.

The textbooks are simpler, and the relevant literacy textbooks of that world are added with some spoofs. Originally, Jiang Xue wrote that one red flower plus three red flowers are several, and the flower is still a good-looking peony pattern.

But let Fan Weiye change it to one rifle and three rifles...... How many enemies were killed by a single bullet and five shots fired by the security guards?

The two quarreled endlessly, and finally made a compromise...... So, the flowers and the rifle were on together, and the security guards, Xiao Ming, Xiao Hong, Xiao Hua, and car A and car B, which would never crash, were also put on ......

The school building of Chiji Primary School is very simple, with ten large bamboo houses, bamboo walls, and bamboo gates. The playground is very flat and there are no entertainment facilities, but this is easy to say, and I will get it when I have time in the future.

The tall cedar flagpole erected on the playground is very conspicuous, and a flag of the Hantang Group is fluttering on it at this time.

Regarding the iconic flag of Hantang Group, there are not many people who are willing to participate in the design, but there is a lot of noise. In the end, I had to have an independent forum, and everyone put up their own design drawings and descriptions, so that everyone could comment, one person, one vote...... It's not okay to swipe tickets, because it's really a real-name system here...... There is no award for the selected one, but the name and surname of the designer are indicated in the archives of the Hantang Group.

People who have this design hobby care even more, this is an opportunity to become famous through the ages!

There are those who canvass votes, and there are those who smear each other, and the Internet is full of gunsmoke, a bit like the online writers in that world smearing each other......

In the end, Ye Zihong's design narrowly won over a female traverser named Ni Ling, and I heard that she was also engaged in arts and crafts.

The background color of the flags of the two is red, there is no way, everyone can only choose this...... At that time, the estuary could only provide red dye, but that didn't matter.

Ye Zihong's icon is two upright dragons guarding a large cog. In the big gear, a machine tool wrench is crossed with a Type 1649 rifle in the center. Underneath them is an open book with ten ears of rice standing on it.

There are only two colors in red and black in the whole picture, and the contrast is strong.

It looks very high-end and atmospheric, and the meaning is very ...... Shallow.

The beauty of the female Ni Ling's pictures is beautiful, but it is too artistic.

After losing the election, Ni Ling smiled and said: "It's all my fault, I ignored the identity characteristics of the audience......"

At that time, the flag was hanging on the flagpole and fluttering. The people of the Hantang Group also equipped this flagpole with a fixed pulley so that it could rise and fall.

This was followed by the iconic song of the Hantang Group. The controversy is even greater...... Because there are so many choices for everyone, there are really hundreds of people, and there are still people who vigorously promote the "Soviet March...... In the end, I couldn't settle down, so I decided to use the athletes' march as the iconic song first.

This can't be helped, these people from the Hantang Group, in formal occasions, hear this song the most...... Which model worker congress won't let it go? Which big conference doesn't let it go? Everyone couldn't be more familiar.

As for the lyrics, Yang Youxing, who has been engaged in online cultural creativity, thought hard for several days and wrote the lyrics that everyone reluctantly agreed:

Our flag flutters in the wind,

How majestic our steps are,

Shoulder to shoulder, arm in arm, moving forward,

Contribute to the invigoration of the national spirit.

Like the mountain eagle that spreads its wings and flies,

Like the unstoppable flow of water,

Tenacious struggle, not afraid of difficulties and obstacles,

We fight the sea and ocean;

Like the petrel in a thunderstorm,

Like the dragon fighting the wind and waves,

Our nation wants to be on the land of the world,

Show our glory.

For our future,

For the ideals of the whole nation,

In order to promote the spirit of Hantang Group,

Strive to move forward, forward, and further.

Our flag flutters in the wind,

How majestic our steps are,

Shoulder to shoulder, arm in arm, moving forward,

Spread our thoughts, forever light.

Yang Youxing cautiously said to everyone on the Internet: "Don't spray me, if it doesn't work, let's change it, and if it doesn't work, you can also participate." ”

Not to mention anything else, this attitude is basically recognized by everyone.

However, this will not work, a person named Jiang Tiesheng squirted wildly on the forum: "A well-known ugly face!" Low IQ! ”

No one dared to reply to the post, and no one replied to the post, but that Jiang Tiesheng didn't care about this, he felt much more comfortable after spraying, and at the same time deleted the lyrics he originally wrote.

The origin of students at Akachika Elementary School is not even a problem. All Ming children younger than 15 years old and over 7 years old must join, and even the Xingang people sent ten children.

Hantang Group implements the accountability system. There is no better way to know the local situation than to get the knot, and the students quickly got organized...... Of course, there are parents who don't want to, and thirteen or fourteen-year-old children can also work.

At this time, he asked softly, "Do you still want to rent land?" ”

No one said a word again...... At the same time, the Hantang Group added the first tax for the Ming people, natives, and merchants, the education tax...... Originally, I didn't want to add it, but Director Jianguoan mentioned that it was not a matter of money or not, let alone a matter of a few handfuls of rice...... It's a sense of participation, a sense of responsibility. Now, it's not time for us to play on our own...... After thinking about it, everyone immediately agreed.

After the tax increase order was issued, it did not cause a little ripple among the Ming people. According to the head of the people, one horse a year, that is, one pound of rice, the Ming people and natives expressed their welcome to the increase in education tax.

On the day of the opening of the school, many people from the Hantang Group came, and these primary school students are the hope of the future! Hekou Base, Budai Salt Chemical Base, and Hongxing Industrial Zone all sent congratulatory gifts...... But no one spoke, and no opening ceremony was organized.

Chairman Wu Dapeng and Director Jianguoan carried a long wooden sign and solemnly hung it at the gate of the school. But they didn't cooperate well, and the two of them held the sign and hung it several times before they hung it up, and then they smiled at the crowd and uncovered the red cloth covering it at the same time. The crowd began to applaud and congratulate.

The sign was engraved with four vigorous and powerful characters: Chiji Primary School. This is the result of many days of hard work by Manager Merge.

Manager Mei Lezhi stood in the crowd and admired his big characters, thinking, this calligraphy level is really getting better and better, I didn't expect to be engaged in mundane things all day long, but there is a kind of ordinary taste between the lines, is it related to this time and space?

After hanging up the sign, Principal Hao Gang closed the door of the school with a straight face, and even ignored Chairman Wu Dapeng, and now he is the person with the most power in this school.

During the period of basic education, Chiji Primary School adopts closed management, which is conducive to the rapid progress of students.

The crowd slowly dispersed. Captain Fan Dahai kept staring at the figure of Dr. Qiao Meiyin in the crowd, hoping to walk back to Gelanza City with her, but Dr. Ma Jun always stood beside her, and the two of them didn't know what they were chatting about, endlessly.

Yang Tongsheng, like other Ming people, also stood from a distance to watch the scene.

"Elementary school?" Yang Tongsheng frowned and thought, "Could it be that they want to study the pronunciation of words?" Xu Shen wrote Zeng Yun in "Explaining Words and Words": "Zhou Li" entered primary school at the age of eight, and Bao taught Guozi, first with six books. Duan Yuci also noted the clouds: The son of the country, the son of the minister's doctor, the teacher's family, the Bao's family, and the son of the world are also toothy.

And these people from the Hantang Group can even teach the children of the mud legs to lead the car and sell pulp, and the mud legs of the farmland can be raised, and their ambitions are not small! ”

He nodded in the crowd, no matter what, it's a good thing to have no class, it's just that the calligraphy in the big characters is too kitsch...... However, in terms of primary school, why don't the people of Hantang Group ask me for advice?

Thanks to yezhongye, Melage, and old friends who don't mess with alcohol for their support. Thank you for the red envelope of the hippopotamus elephant...... Welcome new friend dd2892785.
