The bearings have been made and installed on the waterwheel, and there is no creak when the waterwheel rotates before, and it is very moist.

Since the waterwheel can run 24 hours a day, the vegetation raw materials needed for papermaking can be pounded out faster.

"How long did it take to mash it into pulp?" Yang Ming took a group of officials to the paper factory in Chang'an County and asked Yuanshou Dao.

Yuan Shou replied: "If you are artificial, the pulp used in a piece of paper will take about ten years, and now, three days." ”

A piece of paper is a knife of paper, a hundred sheets, ten days is ten days, which is equivalent to shortening the time of seven days, and the efficiency has improved a lot.

But the most time-consuming part of papermaking is actually drenching, that is, seven to eight months of rain and sun, this process is to change the lignin and pigment structure with ozone in the air, so as to achieve a bleaching effect, and can improve flexibility.

After drenching, the raw material will directly change from gray-brown to white.

Because it takes too long, the raw material of the dried bark will be divided into three parts, the two months are coarse linen paper, the three to six months are jute paper, and the July and August are white linen paper.

It is equivalent to the ten-year, twenty-year, and thirty-year-old of Fenjiu Group.

This process is not easy to save, because the wood contains lignin, and the lignin itself is yellow, and later generations used the chemical bleaching method, and Yang Ming couldn't get those chemicals, so it could only be the ancient redox bleaching method.

Although Yang Ming's main purpose now is to make more paper, not to make more beautiful paper, it is indeed too long to wait for seven or eight months to make pulp.

But he has a way, but he can't say it in front of so many people.

"A waterwheel can drive twelve treadmills to pound the veneer of the stone mortar, and this amount is just the amount of pulp used in a piece of paper," Yun Dingxing explained to the ministers:

"That is to say, as long as the supply of raw materials continues, the waterwheel can produce a piece of paper in half a month, because it also needs to be pulped, dosing, papermaking, water filtration, paper pressing, and paper drying."

The pedal is similar to a seesaw, with a fulcrum in the middle, and the person steps on the other side, picks up the mallet on the opposite side, and then drops it to pound the pulp.

The paper mill has both manual and hydraulic pulping, and now the bearings made of refined steel are installed, which is mainly based on hydraulic power, liberating more labor.

Someone is going to ask, there is no shortage of people in Dasui, yes, there is no shortage, but this kind of technology in the professional field is not easy to teach, so the paper factory is equivalent to not recruiting people, it is Lao Tzu with his son, and the master with his apprentice.

Although there is no formal establishment, people are also employees of state-owned enterprises, can you civilians enter casually?

Including the refinery in Hedong, the real technology, ordinary workers can't see it, they can only contribute, and the workers over there are also lucky, just in time for the big expansion of the refinery, they recruited so much, and they won't recruit again in the future.

"It seems to save some time, but it's not much," Yang Yue frowned, "Drenching and soaking are the most time-consuming, and it is best if this process can be shortened." ”

Soaking is to use lime water to blister, lime water is alkaline, can disperse lignin, easier to form pulp, also has the effect of decolorization, the lime soaking process of Dasui, two months.

If you want to shorten this process, in fact, it is the same as drenching, just add a step.

A group of high-ranking officials walked around the paper factory for a long time and dispersed, and Yang Ming left all the people of Taifu Temple behind.

At night, in the shed of the paper mill, Yang Ming said:

"Soaking in lime is to use its acidity and alkalinity, in fact, there is a way, you can give it a try, first soak in lime for a month, then soak and ferment in human urine, and then steam, and then drench after cooking, we look at the time of its whitening."

The officials of Taifu Temple were dumbfounded, aren't you kidding? Paper is a precious thing, how can it be soaked in human urine?

Of course, human urine contains urine-based salts, which are acidic, and urea-based salts can gradually penetrate into the raw materials and dissolve part of the lignin, which has been proven.

Until later generations, when bamboo paper was made by hand in the countryside of Fuyang on the outskirts of Hangzhou, human urine impregnation was still used.

In fact, whether it is soaking, fermentation, steaming, or drenching, it is all to remove lignin without destroying cellulose.

After Yang Ming's words were finished, no one said a word, and everyone's faces were strange, obviously a little difficult to accept the method proposed by Yang Ming.

The things that have been soaked in urine are smelly, and the paper is used to record the scriptures, histories, children, and collections, so how can you use urine?

Yang Ming saw that everyone was silent, and said: "The grain in the field is also made of manure as fertilizer, isn't it very fragrant when you eat it?" ”

"Vomit~~"

I don't know who made such a voice, Yuan Shou was suddenly furious: "Serious discussion, what are you doing?" Get out. ”

The official, who almost vomited, hurried out.

"Hypocrisy," Yang Ming said in a deep voice: "Deduct him for half a year." ”

Yun Dingxing knew that what Yang Ming said was by no means untargeted, urine is sour, and fermentation is fermentation with acidic substances, and the prince's words are not unreasonable.

I just listened to him: "The first is fermentation, then steaming, and it will be cleaned after steaming, and the smell of urine is long gone, if you can really shorten the time, you might as well give it a try." ”

Yang Ming nodded and said: "For today's plan, it is necessary to increase the collection of raw materials, and the cost of making clothes from linen is too high, so it is better to use bamboo, bark, and when adding medicine, you might as well try star fruit vine." ”

Adding paper medicine during pulping can make the cellulose in the pulp float, and the paper can be separated more effectively when the paper is uncovered.

Basically, it is based on the stock solution of various plants.

Yun Dingxing hurriedly recorded.

Yang Ming explained again and went back to the palace.

If he wants to improve papermaking, the process is long, and what he can do is to shorten the time and cost as much as possible, so that the shipment is high and cheap, and everyone can buy it.

In October, Yang Ming received a good news that he had entered the Central Plains, bringing only 2,000 people with him, carrying tributes from the court.

"Shibi is almost in Yanmen, who will we send to pick it up?" Wei Xuan asked at the court meeting.

For the king of a country like Shibi, you have to send a relatively high-level person to Yanmen to greet people, and then take them to Jiangdu, to put it bluntly, to be a guide.

Why did you stop when you arrived at Yanmen?

Because this place in Yanmen County, since the Han Dynasty, has been regarded as the red line between the Central Plains Dynasty and the northern nomads, you make trouble outside Yanmen and call for raiding the border, and you will generally only send border troops to drive it away.

But if you pass through Yanmen County, which is called aggression, the imperial court will directly send troops.

Shibi understands this rule, so he didn't go through Yanmen at the moment, but stationed on the spot, waiting for the court to send someone to pick him up.

"Foreign affairs with the Eastern Turks have always been the responsibility of Changsun Sheng and Pei Gong, the eldest grandson passed away, and Pei Gong was in Jiangdu again," Yang Xuangan frowned and said: "This person is really not easy to choose." ”

Cui Zhongfang said with a smile: "Choice, it is a good choice, it depends on whether you are willing or not." ”

With that, his eyes looked at Yu Wenshu.

Yuwen Shu was stunned: "I'll go?" I've never dealt with the Eastern Turks, so I don't know how to do that. ”

Xuan Gan said: "It's okay, the Ministry of Rites and Honglu Temple will send someone to assist." ”

"Isn't it appropriate for you to go?" Yuwen recounted.

Xuan Gan smiled: "I have a concubine who is about to give birth, and I can't leave." ”

As soon as these words came out, the court suddenly burst into laughter.

Yang Ming was dumbfounded and said: "Then you should go home quickly, don't delay your business because of state affairs." ”

Yang Xuangan was suddenly speechless and lowered his head.

Yu Wenshu also couldn't help laughing and said: "If the old man refuses to go, it is true that he is not through diplomacy, what do you think, how about Tang Guogong?" Shimin will be Princess Shang in Jiangdu next year, and Tang Gong has to go to Jiangdu anyway, isn't this just a good way? ”

"Good idea, it seems that it has to be Tang Gong," Lu Chu said with a smile.

Does Li Yuan want to go? I don't want to go, it's a hard job to be a guide, but he wants to refuse, no excuse.

The imperial examination is also over, and he is also idle.

At this time, Yang Ming's gaze looked at Li Yuan and said with a smile: "Tang Gong has a hard trip? ”

Li Yuan glanced at everyone and found that everyone seemed to recognize him, so he could only nod helplessly:

"The minister is willing to go to Yanmen to pick it up."

"Okay," Yang Ming said with a smile: "The people and tribute that Shibi brought with him, there is no need to picket, the food and lodging on the road are provided by the county guards, you take Zuo Yiwei 2,000 people, go to Yanmen to pick up, and then go south by boat in Luoyang." ”

After saying that, Yang Ming looked at Lu Chu again: "The internal history province has issued a customs clearance document, since people are here, we have to entertain them." ”

"Yes," Lu Chu nodded.

The fact that he was able to come at the beginning eliminated Yang Ming's worries that had lingered for many days, in fact, the bigwigs in the court were also relieved.

Everyone knows that as long as Shibi comes, then in the next four or five years, there will be a peaceful life to live.

With a "scatter", all the officials dispersed one after another, only Yuwenshu refused to leave.

Yang Ming had already gotten up and sat down again:

"What? Is there anything else to do with Xu Gong? ”

Yuwen said hesitantly: "The minister wants to explain. ”

"You say," Yang Ming said with a smile as he tapped on the armrest.

Yuwen recounted: "In the statement of the review of the Ministry of War, the Liang Division said that the minister delayed the military plane, so that the Zhongwen Department almost wanted to be destroyed, and the minister was wronged. ”

Liang Shi is the prince's person, Yu Wenshu knows it, and the other party has been reinstated by the imperial examination official, Yu Wenshu guessed that the prince arranged it behind his back, so he was worried that Yang Ming believed Liang Shidu's words, so he stayed today, thinking about explaining and explaining.

Yang Ming directly raised his hand and said with a smile: "Duke Xu doesn't need to mind, Master Liang is just a general, and Gong is the general of the march, what do you do, he can't understand it, you don't have to explain." ”

"The minister is afraid that the prince will misunderstand," Yu Wenshu said with a humble attitude.

Yang Ming smiled: "No, Lone will not doubt Xu Gong's use of troops because of a small general, by the way, what does Xu Gong think about this time?" ”

Yu Wenshu was stunned for a moment, and said directly: "He is still afraid of me going to the court, this person will be in charge for a day, and my Great Sui Northern Trouble may be temporarily eliminated." ”

"Gong Xu is optimistic," Yang Ming leaned back and said with a smile.

Yuwen said without changing his face: "My Great Sui attacked and destroyed Goguryeo, the country is flourishing, and the Turkic clown will never dare to offend my Tianwei at this time, but what the prince said is that it is indeed not appropriate to be optimistic about border troubles." ”

Yang Ming said casually: "Are you still smuggling with the Eastern Turks?" ”

Yu Wenshu's face changed slightly, and he hurriedly waved his hand and said, "Absolutely not." ”

Yang Ming smiled: "There is a report from the Yushitai here, and Huaji really didn't have any dealings with the Eastern Turks, but how did he get together with the Western Turks?" ”

Yu Wenshu's face changed greatly: "The ministers don't know that there is such a thing?" ”

"Go back and ask him," Yang Ming got up and said earnestly: "Take care of it, don't let him cause trouble for you." ”

Yuwen Shu also hurriedly got up, waved his hand and said, "Congratulations to His Highness." ”
