Open an aircraft carrier to fight against Japan

Luo Chaoying said: "Armor fragmentation bombs have very high requirements for explosives. To achieve the ideal armor fragmentation effect, it is necessary to use very strong explosives."

Su Mao asked: "Then the explosives in our Machine Bureau are not strong enough?"

Luo Chaoying said: "The violentness I mentioned does not mean violent. This violentness is a parameter to measure explosives. Usually, violentness is used to measure the ability of explosives to crush the contact objects. This violentness depends on the products produced when explosives explode. The pressure, the speed of detonation wave propagation."

Luo Chaoying also said: "Let's take a look at the current situation of the Machinery Bureau. The Machinery Bureau can now produce four kinds of gunpowder, black powder, which is black powder; chestnut powder, which is picric acid explosive; cotton powder, which is to put cotton into sulfuric and nitric The nitrocellulose behind the mixed liquid is also a kind of explosive with good force; there is also smokeless powder, which is a propellant with nitroglycerin as the main raw material, which is not considered explosive, and the force of these explosives is not enough to make the armor fragment Destroy the Japanese bunker."

Lin Yuan thought for a while and said, "Then let's make explosives ourselves, and make RDX!"

Luo Chaoying smiled and said, "I can't help you with this. Although gun design also includes ammunition design, it doesn't include how to make explosives."

Lin Yuan smiled and said, "Leave this to me."

Because different types of simple explosives have different explosion effects when mixed, in the modern army, different types of bombs have different requirements for explosives. Propelling the water produces the greatest damage, and the fragmented armor hopes that the explosive can provide the maximum detonation velocity and detonation pressure, so modern military explosives are all mixed explosives based on single-substance explosives.

RDX is the basic component of most modern mixed explosives. For example, the famous American C4 explosive is composed of RDX as the main component, plus a shock agent and adhesive. Among the single-substance explosives, black The explosion energy of Sorkin is higher than that of other explosives, second only to Octogen. Since the cost of Octogen is much higher than that of RDX, the scope of application of RDSR is far wider than that of Octogen. Comprehensive Come to think of it, RDX is the veritable king of explosives.

But like many fields, the best thing is often not the most well-known. For example, when it comes to explosives, everyone knows that it is TNT.

Su Mao asked: "My lord, what kind of black gold are you talking about? What do you need to make it?"

Lin Yuan said: "I'll give you some blueprints later, you can build the machine for the chemical reaction, and let me find the raw materials for the reaction."

The word "chemistry" comes from the late Qing Dynasty, so when Lin Yuan said "chemical reaction", Su Mao was not at all confused, he said: "Okay, I will save the best equipment and craftsmen, and use the shortest Time built the machinery needed for the response."

Lin Yuan said again: "I know that there is a factory in the Machinery Bureau that manufactures nitric acid, which is what you call nitric acid, prepare some more concentrated nitric acid for me, by the way, and then send someone to buy a batch of high-quality candles. "

Although Su Mao didn't know why Lin Yuan asked him to buy candles, he still nodded in agreement.

Hexorkin can be directly nitrated with urotropine and concentrated nitric acid. It has the word "black" in its name, but it is white.Its invention had to wait until 1899, and in that year, a British scientist named Henning obtained a white solid by accident, which he named urotropine, and then he combined urotropine with various acid to study its properties, when treated with nitric acid, a white powdery crystal was obtained, because its molecule is hexagonal, so he named it "hexogen", the Chinese transliteration is "black cord gold",.

Lin Yuan thought to himself: "I have concentrated nitric acid, where can I get urotropine?" He silently thought of a way. He borrowed a cotton robe covered with silk, and after wearing it, he looked like a wealthy young man.

He brought another dead bird, put it in a cage, carried the cage, and walked on the road, attracting passers-by to watch, wondering why he put a dead bird in his cage.

Lin Yuan walked towards the British Concession in Tianjin. The so-called "Concession" can be regarded as a country within a country. Transit point for buying and selling goods.

After Lin Yuan entered the concession, he came to the largest bar in the concession. He knew that many businessmen were in the bar on weekdays, looking for business opportunities by chatting with people.

Lin Yuan dressed up as a wealthy young man. The British knew that rich young men in the Qing Dynasty were both rich and brainless, so when the businessmen saw him, they all tried their best to kill him.

Just as Lin Yuan sat down, a potbellied Englishman came over and asked in Chinese with an English accent, "Have you eaten?"

Among the Chinese greetings, this probably tops the list. Lin Yuan said carelessly: "I've encountered something bothering me, I can't eat it!"

Hearing this, the British felt that the opportunity had come, and said with a smile, "My dear friend, what can I do for you? We have the best drug, just take a sip, and all your troubles will be gone."

Lin Yuan pointed at the cage and said sadly: "See, my baby is dead. Unfortunately, I will die in a few days. I will never see you again."

The Englishman pointed at the bar and said with a smile, "See that redhead, he might be able to help you." After speaking, the Englishman felt that there was nothing left to fish for, so he turned and left.

Lin Yuan walked over and heard the redhead say to the bartender behind the bar: "Why can't you give me another Bloody Mary today? It's not that I don't have money. Wait until I sell the goods..."

The bartender laughed and said, "Our boss doesn't allow you to pay on credit anymore. You can buy bars after your goods are sold."

Lin Yuan took out a few pounds, put them on the bar, and said with a smile in English, "I'll treat this gentleman to a Bloody Mary."

The red-haired man looked at Lin Yuan gratefully, and said with a smile, "My friend from the Qing Dynasty, why did you help me?"

Lin Yuan pointed at the dead bird and said, "I heard that you can keep it from rotting, right?"

The redhead smiled and said, "I have formalin in my hand. If you soak the bird in it, it won't rot."

Lin Yuan thought: "Half the success, formalin is formaldehyde solution, with formaldehyde solution, and find another thing, you can make urotropine."

Lin Yuan asked, "How much formalin do you have?"

At this time, the bartender had already mixed a glass of Bloody Mary and put it in front of the red hair. The red hair drank half of it at once and said with a smile: "I have several tons."

Lin Yuan asked, "Why do you have so many?"

The red hair smiled and said: "Our family has been in business since the age of great voyages. I don't want to sell some steel or wool to the Qing Dynasty. I want to do things that have never been done before. The Qing Dynasty has [-] million people. Most of them are farmers, so I thought it would be appropriate to transport fertilizer!"

Without waiting for him to finish telling the story, Lin Yuan interrupted him excitedly, and said, "You have fertilizer too?"
