Chongzhen Undergraduates

The two female masters behind Jiu'er remained silent all the time, as if these words had nothing to do with them, they stood motionless.

"My father may have to go to Huguang, and it will take a long time." Among the three cheap children, Zhu Youjian likes Jiu'er the most. This girl is very sensible, lively and cute.

"Can you take me with you?" Jiu'er was taken aback, and asked Zhu Youjian tentatively, holding the other empty sleeve.

"It's a bit dangerous, I'm afraid..." Zhu Youjian was a little embarrassed, seeing Jiu'er's expression, he probably remembered the matter of the capital again.

"We will protect the princess." Yang Jing blurted out without thinking.

"Tch! Sister, you just want to follow him." Fang Yi's words made both Zhu Youjian and Yang Jing blush.

"Can you stop being so direct?" Zhu Youjian was so stunned that he couldn't get off the stage, he was a little afraid of this woman.

"I'm not going anyway, I haven't visited Nanjing enough yet." This time, Fang Yi didn't join in the fun, which was quite surprising.

"That's it. With the three of them accompanying you, my father is at ease." Zhu Youjian and Yang Jing glanced at each other, a couple of men and women tacitly understood.

As long as he is in Nanjing, the most important thing for Zhu Youjian is of course Fang Yizhi's progress here.

"What are the materials that have improved the process?"

Zhu Youjian saw that Fang Yizhi was holding a bun in his hand, sitting behind a pile of documents, put down the lunch box in his hand, filled a bowl of porridge, and opened the documents in front of Fang Yizhi with his hands.

"You know, start with the purification of gunpowder ingredients, sulfur and saltpeter; then sulfuric acid, nitric acid, and hydrochloric acid. Using the chemical element table and some formulas you gave, it's not difficult to get them out.

The difficulty is that the output is too small, only enough for us here. "

Well, as the basis of chemical engineering, Zhu Youjian certainly knew that everything needs to start with three acids and two alkalis. He originally thought that this would be a difficult process. Many time travel books have written a bunch of technical ones seriously. chapters to explain these things.

It turns out that the discovery and invention of anything follows a reasonable process.The clever team of the Institute of Technology started with the improvement of gunpowder, followed the raw materials of gunpowder, and solved the problem of three acids and two bases.

Of course, if this is a conventional development route, it is estimated that it will take hundreds of years.The problem is that Zhu Youjian has already pointed out the direction, and they only need to follow this direction.

Contrary to Zhu Youjian's expectations, this group of people found a shortcut, but they didn't just get three acids and two bases for the same thing.

"What about glass? Can glass be made?" As an artifact of time travel, too many writers of Mingchuan write about glass as a top priority.

"Your majesty, have you made a mistake? Lao Song said that colored glaze is not a rare thing at all, and the Ministry of Internal Affairs has always made it."

The glass manufacturing process in ancient China began in the Western Zhou Dynasty. After more than two thousand years of continuous development, it reached its peak in the Qing Dynasty and became the heyday in the history of ancient glass.The Palace Museum has more than 4000 pieces of ancient glassware.

The monochromatic glass of the Kangxi Dynasty is the inheritance and development of the glass making process before the Qing Dynasty.The handed down products of this period were only known in the past as a transparent glass water stand in the collection of the Palace Museum in Beijing.During the Yongzheng Dynasty, monochromatic glass was the most widely produced variety and the most abundant variety, which was the mainstream product at that time.Monochrome glass can be divided into "Nirvana glass" and "bright glass", "Nirvana glass" refers to opaque glass, and "bright glass" refers to transparent glass.

"According to the method you said, add soda ash and try to make some. It's in the box behind you!" Fang Yizhi pointed, and Zhu Youjian turned to open the box, revealing a bunch of bottles and jars.

"Your sister." Zhu Youjian scolded some people from the bottom of his heart. He really thought that the technology of the Ming Dynasty was so backward. In fact, it had accumulated to the moment when it was about to explode, and all it needed was a guiding light.

"The blast furnace and the converter have also been produced?" Zhu Youjian couldn't believe it. Could it be that this group of people are really so against the sky?

Chapter 153: Spending money like running water (this chapter is purely technical, I don’t like to bypass it)

"This one is really troublesome. It was blown up several times, and more than a dozen died. A layer of skin on Lao Song's arm was burned off."

"Ah! Is it important? You can't let Song Yingxing have an accident." Immediately, Zhu Youjian was worried for Song Yingxing again. If something happened to this guy, it would not be easy to find another one.

"Should be fine, I hear he's back to work the next day. A big can of badger oil."

There will inevitably be losses on the road of technological progress, and it is common sense like Nobel, but a large can of badger oil really scared Zhu Youjian enough.

"Send Nanjing's imperial doctor to show Lao Song, Amitabha, Lao Song must not have any accidents."

"Pfft!" Fang Yizhi was amused by Zhu Youjian's expression.

"Did you make the gunpowder pellets?" Zhu Youjian tried hard to think about some plots in the time travel novel, trying to find the so-called "artifact" in it to confuse Fang Yizhi.

"To make gunpowder, each material uses five catties of nitrate, one catty of yellow, and one catty of eggplant stalk ash. The above-mentioned nitrate, yellow, and ash total seven catties, which are divided into three troughs, and [-] pieces are fixed for grinding, and then they come out of the trough. One catty, use one catty of shochu, turn it into mud, and still put it in the trough, and then grind it for a hundred times, and then get out of the trough.

Mix it into granules, which are as big as yellow rice or mung bean, and it must be put into the palm of the hand without feeling the heat. ——Qi Jiguang. "

"Don't you just say that the granule gunpowder has long been available?" Zhu Youjian lost face. He wanted to show off the so-called "artifact" in front of Fang Yizhi, but he didn't want to be counterattacked.

"The particles are not uniform, some are as big as yellow rice, and some are as big as mung beans. It is necessary for the machinery group to create a suitable production machine that can evenly produce particles of the same size."

Zhu Youjian joked: "Hey! You've changed, why are you so rigorous? Don't you always use words such as approximately and approximately?"

After stuffing the last piece of bun, Fang Yizhi wiped his hands and said, "What we are doing is science, so we must have a rigorous attitude."

Seeing Fang Yizhi's terrified look, Zhu Youjian felt upset, and must get back his face today.

"Did you find the Eucommia gum? Can it be used as a wheel?" There is no such thing as rubber in Ming Dynasty in this era.It is said everywhere on the Internet that Eucommia gum is used instead of rubber after time travel, and it is said that there are noses and eyes.

"Let's go, let me show you, the content of that thing is very low, and only a few carts of Eucommia came up with a pot."

Fang Yizhi brought Zhu Youjian to a laboratory, pointed to a yellowish-brown thing and said, "It will soften in warm water, it will soften in boiling water, and it will harden in a little high temperature. Are you sure you want to use this thing as your own?" For wheels?"

"Haha..." Zhu Youjian didn't imagine tires, but Durex, which was neither soft nor hard at thirty or forty degrees.

"Can the waterwheel drill the barrel of a gun?" Zhu Youjian was no longer interested in looking for certain products to save face, he wanted to care about the production of weapons.

"Not at all. To achieve a clean and tidy barrel wall, the drill bit must rotate stably and evenly, and it must be a high-speed drill bit. The runner driven by the waterwheel cannot achieve a uniform speed at all, and the rotation speed is not fast.

Even with the latest invention of bearings, it only enhances stability. "

Zhu Youjian recalled the scene in a time-travel novel where dozens or hundreds of waterwheels drilled the barrels of guns.It is estimated that more than half of the production is waste.

It is a wild hope to expect a bolt-action rifle before the invention of the steam engine.With the existing power to drive the machinery, it is still possible to satisfy the flintlock gun, but it is difficult to make a Mini rifle.

"You just said the bearings were made?"

This is a very detailed one. Any machine starts with a small screw assembly.Rotation requires bearings, and mechanical components plus bearings, plus nuts and bolts, will show a little sign of industrialization.

The rest is to add a suitable power source, and Zhu Youjian can already conceive an industrialized scene in his mind.

"Yes, everyone didn't expect the bearings to be so easy to use. Experiments have been done. The wheels with bearings are several times more durable than those without bearings. And it is also convenient to repair. You only need to replace the bearings, and the wheels can be repaired soon. on the road."

The biggest loss of ancient carriages is the axle.Walking alone on the official road, you will often see a carriage with a broken axle on the road.If a carriage does not carry two or three spare axles, it will not dare to travel long distances.

Compared with the advantage of Houjin's large number of horses, Zhu Youjian can only find a way from the vehicle to offset the pressure brought by logistics.

"What other good things did the mechanical group make?" Zhu Youjian couldn't wait any longer. It's been half a year, so he couldn't just make these things, right?

"Nuts, bolts, bearings. That's all."

"What? That's all?" Zhu Youjian was very dissatisfied. Isn't this speed too slow?

Fang Yizhi gave Zhu Youjian a look, and said: "After these few samples came out, all the production equipment had to be remanufactured. The mechanical team is so busy that it's so busy."

Well, Zhu Youjian is right when he thinks about it.When the standard parts come out, it is natural to standardize and improve some of the original appliances.
