Under Wang Xuexin's "coercion and inducement", Asano Aihara could only outline the production process.
In principle, Wang Xuexin does not need this, he can just use the new production method.
However, when it comes to acting in a complete set, technological progress requires a process, so Wang Xuexin can handle it easily at both ends.
Otherwise, it will be a new technology when it comes up, and both sides will be suspicious. When they ask each other... the secret will be revealed!
Asano Aihara took a pen and wrote down the process in detail, adding precautions. Wang Xuexin translated it into Chinese and copied it.
There are eleven steps in the whole process. The so-called "solvent extrusion gunpowder forming method" is to dissolve nitrocellulose in water and volatile solvents, then add auxiliary agents and plasticizers, and filter out water and excess solvent.
Then stir and calender it to become a solid gunpowder column.
Then Asano Aihara made several lists, including the required raw materials, general supplies and machinery and equipment... The Japanese's caution was clearly demonstrated here. He even divided them into categories and listed the approximate percentages of each raw material one by one.
.
Wang Xuexin took the raw materials and looked at them individually, and immediately felt a big headache.
What methylene bisacrylamide, what tetramethylethylenediamine, or the organic monomer acrylamide...
Wang Xuexin has never heard of these things, and he probably won't be able to fix them at the Fifth Factory.
The same is true for the list of machinery and equipment. Horizontal mixers, differential speed constant temperature calenders, etc., as soon as you look at the names, you feel that they are out of reach.
Wang Xuexin originally wanted to pretend to do it and then slowly improve it, but he gave up when he saw these things... Damn it, the cost of acting is too high, not to mention that two of the processes use 100 degrees.
Roller calendering.
Wang Xuexin asked Asano: "Won't this explode?"
Asano replied: "Of course, fire accidents often occur. If the chemical added to the differential rotating roller is too dry, an explosion will occur! So we have to be extra careful and prepare fire-extinguishing equipment, but even this can only
It can reduce the probability of fire and explosion, but it cannot fundamentally eliminate fire and explosion accidents!”
"So..." Wang Xuexin asked: "How did you survive until now?"
Asano pushed up his glasses and replied: "Did you think we only had twenty-one from the beginning?"
Wang Xuexin:……
Later, Wang Xuexin learned that Asano's subordinates originally numbered thirty people, nine of whom died in the accident.
After that, Asano strictly controlled the production volume, that is, small-dose production, so even if an accident occurred, the damage caused would not be significant.
One thing Wang Xuexin couldn't understand was that Asano and his team looked very cowardly and fearful of death, but they behaved very bravely when producing propellants.
Asano's response to this was: "Well, I haven't thought about this problem. This is work, right? Although it is dangerous, it must be completed!"
Can this be said to be the conscientiousness of the Japanese?
But no matter what, Wang Xuexin was unwilling to come back alive from the battlefield, but had to sacrifice at work.
So he had a showdown with Asano: "Why don't we try another method that doesn't require the dangerous process of roller calendering!"
"Of course we have tried!" Asano replied helplessly: "But we can't effectively mix the gunpowder evenly. Do you know what the consequences of uneven gunpowder are?"
Seeing Wang Xuexin's confused face, Asano explained: "For example, when we test-fired, the 'spray bomb' that suddenly turned..."
Wang Xuexin said "Oh", if the gunpowder is uneven, it will not only be a problem of wind deflection, but also the jetted airflow will be asymmetrical, causing uncontrollable Brownian motion in the air.
For this kind of rocket, you can't even ask it to fly in the direction of the enemy. It will probably circle in the air and hit you... Ah San is good at this.
After thinking about it, Wang Xuexin said: "Try a new method, this method makes no sense to us. In addition, as I told you, we know much more about it than you think, so we will use Geng
Using alkane as a synthetic raw material and a certain alkyl nitrate ester as a plasticizer, you can easily get the effect you want!"
(For reasons of harmony, the recipe cannot be written in too much detail and can only be represented by "some")
Asano was stunned for a moment, then widened his eyes and said, "Really? Is it heptane? It turns out heptane is used! That's right. It is a solvent and a raw material for organic synthesis. It can make these raw materials
Fully dissolved together!”
Wang Xuexin didn't know what was going on. Anyway, he couldn't understand a lot of things written in the system information.
In fact, there is no need to understand it, as long as you know that the result can be calculated, no matter what the principle is!
However, after listening to Asano's words, I feel that it is true that a big problem with this solid gunpowder column is its "uniformity". For this reason, he did not hesitate to use a 100-degree roller to repeatedly stir and calender it.
If there is a certain synthetic raw material that can fully dissolve the components of gunpowder and solve the problem of "uniformity" in the liquid state, then naturally there will be no need for rollers to stir and calender.
Then Asano became nervous. He took the paper and pen and asked: "Sir, can you tell me the formula? Also, the process of making this kind of solid gunpowder!"
Wang Xuexin looked at the paper and pen in Asano's hand, and thought to himself that this was a great help to him... If you wrote it down in Japanese, wouldn't there be proof that it was a Japanese technique?
But there is still a loophole. What should this devil do if one day he tells others that this is not his skill?
Thinking about it, Wang Xuexin pretended to be embarrassed and said: "Asano, it's not that I don't want to say it, this is a military secret..."
Asano said "Hey": "But, Your Excellency, this may be very helpful for our research and development..."
Wang Xuexin pulled Asano aside and said, "If you happen to have this kind of technology, then it will be no problem!"
"That..." Asano was confused when he heard this: "But, Your Excellency, we don't have this technology!"
Wang Xuexin said: "If I teach you, won't you be able to do it?"
"But Your Excellency!" Asano looked at Wang Xuexin aggrievedly: "You can't teach because of military secrets!"
Wang Xuexin felt a twinge of anger in his heart. This Japanese guy was so stupid, why didn't he get his wits about him?
There was no way, Wang Xuexin could only make it clear: "If anyone asks, just say it's yours!"
Asano was stunned for a while, then suddenly realized, he bowed repeatedly and said: "Yes, thank you very much! I will keep it secret for you! Please rest assured!"
Perfect, no flaws!
So Wang Xuexin no longer hesitated and read out according to the information in his head:
"46% nitrocellulose, 38% certain alkyl nitrate ester, 3% certain alcohol..."
"The process, the first step is to mix the raw materials into a slurry with heptane, and then add the plasticizer. This process must be thoroughly mixed so that the plasticizer coats the surface of the solid particles and is evenly distributed in the medicine body. The second step,
Dry. The third step is to pour the gunpowder into the mold and press it into the desired shape!"
Asano was so surprised that his jaw almost dropped. After a long while, he looked at Wang Xuexin in disbelief and asked: "Sir, are there only three processes?"
