The weapon tycoon who traveled to Daqin

With the principles of these generators, it is easy to make electric motors, because the materials are there, and there is no need to collect a lot of materials around.Moreover, some things can be processed by themselves, and this is a simple experiment, mainly the positive results of the experiment. If it is processed, it will take some effort. Shang Wen paid all his attention to the results of the experiment, and didn't even notice what Meng Yi said.

The motor made by Shangwen is very simple, and the principle of the simple road can be understood with a little explanation.This is very similar to the world's first electric motor.But it was the first electric motor of this era.Although it is a bit crude, it is the ancestor of electric motors in the future.

"Well, what did you say?" Shangwen asked, setting up the generator device, and then connecting the wires together.All wires are exposed without any insulation.That's because the insulating material comes from the tropics or the tropical zone, and there is no such latitude zone in Qin State.Even so, Qin State is actively expanding eastward, and has no intention of developing southward. If the strategic direction cannot be changed, many things cannot be produced.Shangwen has long wanted to attack the south, especially the idea of ​​letting the unification war give way to the resource war. The industry needs a lot of raw materials for processing, but Qin's geographical location is far from having these things.If it was the state of Chu, Shang Wen felt nothing, but this is the state of Qin, and there is no outlet to the sea.Yes, just a lot of land.These have restricted the development of industry.Next, Shangwen intends to persuade King Qin to start a war in the south. The army investment is not much, only 2 to [-] people. The most important thing is to adopt step-by-step methods to provoke wars among the barbarians in exchange and purchase.In exchange for a large number of Yue people slaves, at the same time, the Qin army sent a small group of troops to participate, or formed a large number of mercenaries to participate, and gradually controlled the south in the hands of Qin.

Use barbarians to control barbarians.Launching a slave war is the most effective control method, and it is very thorough, so that it can completely solve the problem of ethnic minorities that has not been resolved for thousands of years. clear the land.It is not like using a large-scale army to carry out encirclement and suppression as in later generations. If the encirclement fails, it will be appeased.This is an extremely wrong approach, and it is very one-sided.In Shangwen's move, the solution is to solve it fundamentally.To adopt uncompromising and non-negotiating measures against ethnic minorities is to severely attack them.Significantly reduce their population, annex their lands, and provoke wars between tribes.When a nation's population is reduced, the branches of a big tree are cut off, and their land is annexed, which means that the roots of the big tree lose their connection with the soil. If the roots lose the soil, there will be no nutrients.After a long time, it will wither and become a rotten piece of wood, and then you can do whatever you want.

This method is a little slow, but it is very thorough. As long as it is implemented in an all-round way, within a year, Qin's territory will expand by two counties.Thinking of this, Shangwen began to make preliminary estimates.If this is the case, it will take at least two years to reach the belt area, and the time is still a bit slow, which is really a big blow to the industry.Shangwen's hand accidentally touched the wire, and his hand was a little numb. Fortunately, the voltage was not too high.But Shangwen was a little anxious.This speed is still very slow.If the army is used, it will seriously interfere with Qin's overall strategic planning, so Shangwen can only think of another way.

"My lord, this is a letter from the north." Meng Yi reminded again.

"What." Shang Wen said after recovering.

Meng Yi pointed to a piece of wood in his hand.

"Oh, I'm sorry. I was distracted." Shang Wen waved his hand to signal, and then it turned out that Meng Yi's wooden board and Qin Guo's handwriting were too difficult to understand.This letter came from the northern Guyang Iron Works.

The content of the letter generally stated that the iron in the iron factory has kept up with the huge demand, and now it has begun to use more than [-]% of the original stored iron ingots. The situation is very urgent.Desperately need my own help.

199 Dry distillation products

After Shangwen quickly read it again, he felt that the current problem was a bit tricky.

The tricky thing is not how to smelt iron.Rather, it is to maintain the industrial base at the current high-speed start-up stage.The technology of iron smelting is easy to solve, as long as the blast furnace is modified, and a large amount of dry distillation coke is enough.The coke method is easy to make. When Shangwen was in the north, he planned to dry coke, but it was delayed due to the incident at the Xianyang Arsenal.Thinking about it now, if the adjustments could be made in time at that time, it is estimated that today's situation would not have happened.

The method used by Guyang Iron Works is an old method, although the method of adding charcoal to the crucible was also found, the method of charcoal was somewhat outdated at that time.And it can't meet the current large-scale demand.

Since it began to be equipped with a large number of guns and artillery, locomotives and machine tools appeared.There has been a surge in demand for iron.The exact number is unknown, but iron ingots and coal ox carts from Guyang in the north to Xianyang continued continuously, and more than half of the roads were filled with ox carts transporting iron and coal.If it is transported and used in this way, the only iron stock will be consumed soon.

Guyang is a new iron factory. Qin currently has two iron-producing places, and the other is Yiyang. It used to be a place in South Korea, but it was quickly taken down by General Baiqi of Qin.

The current situation is that production adjustments must be made, and this is no longer a matter of building more blast furnaces.This is to be upgraded.After the iron is upgraded, steel can be produced on a large scale.

Thinking of this, Shangwen began to calm down and write the method of making coke.Then how to use this coke for large-scale iron smelting.While Shangwen was writing, the door rang.

"My lord, little Bai Ai, can you come in?" Bai Ai asked.

"Come in." Shang Wen bowed his head and said.

Bai Ai came in quietly.Because he knew that this adult had a habit of prohibiting others from disturbing him when he was thinking about problems.Therefore, Bai Ai has always been very careful, and began to imitate Shangwen to do some thinking.

"Tell me, what's the matter." Shang Wen still said with his head buried.

"What the adults asked the little one to do has been done. This is the finished product of dry distillation." Bai Ai said as he put down a bag, and took out some bottles, jars, and a few pieces of black things from the bag. "

"Oh, let me see." After Shangwen finished writing what was in his hand, he saw the coke in Bai Ai's bag.

"You made this coke?" Shang Wen asked.

"Coke? Oh. That's what your lord is talking about." Said Bai Ai, pointing at Coke.

"Yes." Shangwen immediately stepped forward to pick up the coke and said.

"I asked you to dry distill sulfur, saltpeter, and wood. Why did you dry distill coal?" Shang Wen said.

"Hey, I'm curious. So..." Bai Ai said with some embarrassment.

"It's nothing. There's nothing wrong with being curious. It's a good thing, and human beings should maintain curiosity." Shangwen held the coke and saw.

"Just, pay attention to safety in the future and don't hurt yourself." Shang Wen said.

"This thing is used for smelting iron. What I'm writing is the method of making this thing. I didn't expect you to send a sample. Very good, I will send it to the north later." Shang Wen said.

"Is that sulfuric acid obtained from sulfur? Is that nitric acid obtained from dry distillation of saltpeter?" Shang Wen asked.

"This, this is sulfuric acid. This is nitric acid. This is obtained from wood. It smells like wine." Bai Ai pointed and said.Nouns such as sulfuric acid and nitric acid were quickly accepted by Baiai.

"Well, very good." Shangwen picked up the sulfuric acid and said.

"This is sulfuric acid. It is a strong mineral acid with high corrosive properties. It is generally transparent to slightly yellowish. It has a high boiling point and is easily soluble in water. It has different properties at different concentrations, so it has different applications. , is also the raw material of many chemical products. It can cause great damage to the skin through different reactions, so you should be more careful when using it." Shang Wen said holding the clay pot of sulfuric acid.

"This is nitric acid, a strong oxidizing and corrosive inorganic acid that is easily soluble in water and completely ionized in water. At room temperature, its dilute solution is colorless and transparent, and its concentrated solution is colorless and transparent, but concentrated nitric acid is easy to decompose and produce Nitrogen dioxide shows brown color at room temperature. Nitric acid is unstable and easily decomposed by light, so it should be stored in a brown bottle in a dark place away from light." Shang Wen said holding the clay pot of nitric acid.

"That's why I don't let you touch these things casually. It's very scary to be contaminated with these things. These two things, nitric acid and sulfuric acid, and glycerin are extracted from animal fats to make nitroglycerin. A It is a yellow oily transparent liquid. This kind of thing is very smiling, as long as it hits it, it will explode. It is more than ten times more powerful than the granular gunpowder used in artillery." Shang Wen said.

"It's so powerful." Hearing Shang Wen's introduction, Bai Ai's heart was a little restless, he was eager to create the powerful nitroglycerin that Shang Wen said.

"I'll do the experiment on nitroglycerin. It's too dangerous, you don't know the properties of nitroglycerin at all. Do you understand?" Shang Wen looked at Bai Ai and said.Shangwen knew that this child had a strong curiosity and wanted to try everything.Especially what you have said is very bold and curious, but there are also many things.

"En." Bai Ai nodded.

"The one that smells of alcohol you mentioned is this clay pot, right?" Shang Wen said.

"En." Bai Ai nodded and said.

"You used the dry distillation of broad-leaved wood, so you can get this thing, and you have also gone through preliminary processing." Shang Wen said with a smile.

"When crude wood vinegar is clarified, the upper layer is clarified wood vinegar, and the lower layer is precipitated wood tar. The clarified wood vinegar contains acids (mainly acetic acid), alcohols (mainly methanol), esters, ketones, and aldehydes. Classes, furan compounds and carbohydrates, etc., the residual liquid obtained during distillation is dissolved wood tar. The acetyl group in the raw material is the main source of acetic acid, while the methanol comes from the methoxy group. The hard broad-leaved wood is more dense than the coniferous wood Contains more acetyl groups and methoxy groups, so it is often used as the main raw material for the production of acetic acid and methanol. The resulting acetic acid is used to make cellulose acetate, acetate, etc., methanol is used to make formaldehyde, etc., and solvents are used for paints , Textile and other industrial sectors. Wood tar antipolymerization agent can be used in synthetic rubber industry. Creosote oil can be processed to obtain creosote and industrial creosote, which can be used in medicine and organic synthesis industry. Light oil can be used as flotation for mineral processing Foaming agent. Wood asphalt can be used to make casting core binders and asphalt paint. The main components of wood gas are carbon monoxide, carbon dioxide, methane, ethylene and hydrogen, etc., and can be used as fuel.” Shang Wen said a lot.

"Mister knows about the contention." Bai Ai nodded and said.

"I know so much. Look at this." Shang Wen walked to his desk, took out a stack of papers and handed them to Bai Ai.

200 production adjustments

"This is the process of some chemical experiments I wrote. You can take a look, but I don't do the experiments that I marked as dangerous for the time being. I will do the relatively simple experiments first. I will teach you about those dangerous experiments after I finish. " Shang Wen handed Bai Aina a stack of papers, these are some chemical experiments selected by Shang Wen Jing that can be done temporarily.The main thing is that it is convenient for you to be able to do it at any time.It took Naofumi a whole night of work to complete it.

"This." Bai Ai hesitated, but slightly stretched out her hand trembling.He is very curious, very curious, curious about those chemical experiments that can produce many novel things.When making those dry distillation objects, Bai Ai observed carefully.

Shangwen saw that Bai Ai liked it very much, but he was embarrassed.So he took the initiative to go forward and hand it to Bai Ai.

"Go. Study it carefully." Shang Wen said.

Bai Ai was a little excited.There has never been a master who would teach everything like this.

Bai Ai's eyes burst into tears.

"Why are you still crying? It's nothing. It's really nothing." Shangwen said.

"Master, please be respected by the apprentice." Bai Ai fell to her knees on the ground with a slap.

"Get up. Get up. This is not about master and apprentice, get up." Shang Wen immediately helped Bai Ai who was kneeling on the ground.

"These things belong to all human beings, and they are the crystallization of human wisdom. I don't know how many people spent a lot of time and energy to research them. Could it be that they can be taught just by the relationship between a master and an apprentice? "Shang Wen asked back.

"If you think this way, you are very wrong. It also disappoints my hope. My hope is that these things will benefit all mankind. The relationship between master and apprentice can only teach one person. How can a person's thinking think so Many. These things not only need to be taught, but also taught a lot, many people think about it, and many people do it. The relationship between master and apprentice is narrow.” Shang Wen said.

"Our model is that the master accepts a closed disciple, and then devotes all his possessions to the entire church. But, will it be good if we do this?" Shang Wen asked.
