Kong Jie was full of expectations. This field fertilizer was cheap and was actually ammonia sulfate fertilizer, an excellent nitrogen fertilizer.
In order to encourage farmers to plant crops and increase production, the Japanese sell this kind of fertilizer in major counties.
Kong Jie also searched his memory. He remembered that during the Anti-Japanese War, the Jinsui Army's arsenal seemed to have used mixed explosives made from fertilized field powder, so he came up with the idea in front of him.
If the repair shop can successfully use this fertilized field powder to make explosives, this can fully meet the needs of independent regiments to produce and use explosives on their own.
In Kong Jie's expectation, Dong San on the side began to introduce. He grabbed an explosive pack in his hand and introduced excitedly: "Captain, you see, this explosive pack is what our repair shop has been doing for more than half a month. Through the exploration of time, the newly produced mixed explosive of ammonia sulfate and ammonia nitrate was produced.”
"Speaking of which, I really admire your vision, Commander. How do you know that the Japs' fertile field powder can also be used to make explosives?"
Kong Jie smiled and said: "Stop talking nonsense and talk about business."
"Hehe, yes, Captain, please see, we use ammonium sulfate and ammonium nitrate extracted from fertilized field powder to make a mixed explosive, that is, the explosive package in front of us. Compared with the explosive packages commonly used by our troops in the past, this explosive is not much more powerful. Not small, even bigger. Thanks to the characteristics of this fertile field powder explosive, once it explodes, it is dry and brittle, and it will shatter into pieces. If the amount of gunpowder is enough, a one-time explosion can even directly blow up the Japanese. tank."
"The most important thing is that the raw materials are cheap and easy to obtain! At present, our repair shop has initially mastered how to extract ammonium nitrate from fertilizer powder, and then make this kind of mixed explosive. As long as the amount of fertilizer powder is enough, We can definitely achieve mass production.”
This is a great surprise!
Kong Jie was ecstatic in his heart, and he suppressed his temper and asked: "We can produce explosives ourselves. This is a great thing. However, when it comes to explosives, we must be cautious enough. This may cause the explosive reserve to explode. That is not a joke." Just kidding, you probably still remember the last explosion in the workshop, right?"
Dong San said: "Captain, don't worry. Now that we have figured out the characteristics of this fertilized field powder explosive, we will not easily commit such stupid things again. This kind of explosive bag is mainly sensitive to changes in temperature. As long as we avoid open flames and avoid It is not easy to explode under high temperature and other conditions, but it is relatively safe."
Kong Jie thought for a while and said: "In this way, our repair shop is limited in scale after all, and it can only be a small operation at most."
"About our process of making explosives from fertilized field powder, the specific method includes a series of precautions. After the production technology of fertilized field powder explosives is perfected in our workshop, you will write a manual, and write the details in the manual. Understand how to use fertilizer powder to make this kind of mixed explosive."
"Captain, do you want to hand over our method of making explosives from fertilized field powder to the arsenal?" Dong San asked.
Kong Jie said: "What, you kid can't bear to part with me?"
Dong San hurriedly said: "How can we do that? Captain, you came up with the idea of making explosives from fertilized field powder. Besides, our original intention of making explosives is to deal with the little devils. If our headquarters arsenal can master the method of making explosives from fertilized field flour, Only by using the method of explosives can we truly achieve mass production and supply it to the entire military, which is a good thing."
Kong Jie smiled and said, "That's right if you think so."
"Oh, by the way, after this explosive is produced, it cannot be called Feitian powder explosive. That will easily attract the attention of the Japanese. If the sales of Feitian powder are cut off again, we will not even be able to get the raw materials."
"In this case, since this fertilized field powder explosive was developed by you Dong San and your team, let's call it "Dong San Explosive"! In the future, when the soldiers in our army use this explosive to kill the Japanese, they will also be able to think of this explosive. It was developed by you, Dong San."
"W-how am I embarrassed about this!" Dong San scratched his head, looking flattered.
Kong Jie said, "Really? If you don't want it, then I will change the name of another master in the repair shop."
"No!" Dong San panicked, "Captain, I've already thought of a name for this technical manual on how to use fertilizer field powder to make explosives. It's called "Dong San's Explosive Manufacturing Method."
Kong Jie: "..."
"You kid, you are really not subtle at all."
Dong San smiled even brighter. Looking at the captain's smile, he knew that he had promised himself.
He seemed to have imagined the future situation in his mind. The Eighth Route Army soldiers were charging towards the Japanese with Dongsan explosives in their hands. They used these explosives to blow up the Japanese machine gun fortifications and bunkers and gun towers. Whoever got the explosives wouldn't give Dong San a thumbs up?
In an instant, Dong San felt that his whole body was full of energy.
We must perfect this fertilizer field powder explosive technology.
"Captain, I propose that we expand a part of our repair shop and use it as an explosives factory, specially used to produce our fertilized field powder... No, it's Dong San's explosives!"
Seeing Dong San getting more and more excited as he talked, he couldn't help but want to turn around and continue to be busy with his great Dong San explosives business.
Kong Jie said with a dark face: "You kid, please be more steady. Explosives are dangerous goods. You are so impatient, don't cause any more trouble."
"In addition, I just want to discuss the use of explosives with you."
"Hey, Commander, tell me, do you have any new ideas?"
Dong San asked quickly. He admired his captain now.
From various pictures of transforming weapons to fertilizing field powder to make explosives.
Although the leader is not very proficient in making explosives or repairing firearms, the ideas he comes up with from time to time are always inspiring and enlightening.
To use Dong San's original words of flattery, "Captain, you are half of my master, Dong San."
Back to the present, Kong Jie does have some new ideas about the use of explosives, "Dong San, let me ask you, how are our traditional explosives used? In what aspects are they used?"
Dong Sanyi was startled and replied: "In terms of traditional explosives, explosive bags, grenades, grenades, and landmines, these are the most basic applications of explosives. The main method of use is nothing more than filling these explosives into various carriers , and then projected towards the target. Once exploded, those explosives have completed their mission."
"The little devils are better than us in this regard. Their industrial base is strong, and their various heavy artillery and even bombers make full use of explosives."
"We are much worse in this area due to limited conditions. At most we can make some explosives, grenades, mines, etc., and then find ways to throw some into the enemy's buildings, and some are buried underground. , then caused an explosion, and with luck, a few Japs were killed, and that’s about it.”
Kong Jie reminded: "As you said before, the Dong San explosive we made is very powerful. If the amount of gunpowder is enough, it can even blow up a tank."
"But such a powerful power also means that the risk of detonation is greater. The traditional fuse speed is too slow, and it is actually difficult to control. You have never thought that you can use another detonation method, such as a few hundred meters away. Even thousands of meters away, after seeing the Japs approaching the explosives we secretly planted, they used a special method to suddenly detonate the explosives from a far away place, blowing the little Japs off their feet?"
Dong San said thoughtfully: "Captain, the traditional gunpowder fuse is not that fast!"
"What if it's electric current? Isn't the speed of propagation through wires incredibly fast? The current causes the detonator to explode, which further triggers the explosion of the explosive, thereby achieving a long-distance controlled explosion." Kong Jie said.
Dong San suddenly realized: "I understand, leader, you are talking about the detonator! I have seen this thing in a book before."
