Chapter 121 The solution for heavy taste
Technical problems can be solved by investing capital, but the problem of raw material acquisition depends not only on technology, but also on geographical advantages.

As a kind of mineral, if you don't have it locally, you don't have it. If God doesn't reward you with food, you won't be able to dig it out if you dig three feet into the ground.

So this is indeed the problem.

If you want to develop firearms, as a basic raw material, gunpowder must always be guaranteed.

However, there is no stable output of saltpeter mine, and the bit of saltpeter obtained only by scraping from latrines and pigsties is not enough to boil.

In the composition of gunpowder, nitrate has the largest proportion, the greatest effect, and is irreplaceable. Su Yonglin remembers that the best proportion seems to be more than 70.00%.

At present, the largest saltpeter mines that can be mined are located in Hanzhong and Shuzhong, which are [-] miles away from Shandong, and there is no need to consider them in a short time.

In Shandong and surrounding areas, only Caozhou and Shanzhou produce soil nitrate, which is an alternative.

But Caozhou and Shanzhou are not under Su Yonglin's control right now.

So Su Yonglin faced a very embarrassing problem - there was no saltpeter mine, so he could only collect saltpeter from places like latrines and pigsties to boil.

This will definitely not last long, so Su Yonglin also has related ideas, thinking about when the time is right to take Caozhou and Shanzhou, so that a gunpowder workshop can be built to produce gunpowder stably.

Without a gunpowder workshop that produces gunpowder stably, it is difficult to develop firearms.

However, Caozhou and Shanzhou are currently under the Nanjing Road system, and Su Yonglin has to pass through Dongpingfu and Jeju to reach Caozhou and Shanzhou.

Well, that's a question worth thinking about.

Although it is worth thinking about, it is not the most important problem, and it can be slowed down.

Lin Jingchun was a man of strong action. After receiving Su Yonglin's instructions, he immediately began to act. In a short period of time, he collected a bucket of water and a bucket of urine, and ordered the soldiers of the logistics force to start the improvement of gunpowder.

Add water or urine to the ready-made gunpowder, and stir it into a thicker paste. Do not add too much water and urine at one time, but add them in batches.

After the viscous gunpowder paste is finished, knead them into cake-like objects, put them in a cool and ventilated place to dry, and regrind them when they are completely dry and hard.

In this way, a more stable gunpowder may be obtained.

Then see if water is better, urine is better, or neither.

That's a headache.

There are no low-cost fluids that are more readily available than water and urine.

The gunpowder is drying here, and the work of returning to the teacher is also progressing rapidly over there. In order to survive and gain appreciation, Liu Xi worked very hard. In just three days, almost a usable waterway was cleared out.

Therefore, the loot that the Shengjie Army finally captured through the war can also be dragged onto the ship and taken away, and then returned to Tai'an to strengthen itself.

On the ninth day of the seventh lunar month, Su Yonglin set foot on the road to return to the division, and the victory of the Victory Jie Army officially triumphed.

On the way back to the division, Su Yonglin personally observed the regrind gunpowder on the boat.

He found that the air-dried and ground gunpowder after adding water and urine was more stable than the previous one, and shaking it vigorously in a barrel for a while did not separate the powder on its own.

I squeezed a small handful and put it in the palm of my hand to watch it carefully, and I could find small particles of gunpowder of different sizes, which means that the minimum granulation of gunpowder has been achieved.

Really interesting.

But that's not enough.

"The gunpowder particles can't be too large, you can make a small mesh bag, keep the mesh size constant, put the ground gunpowder in the mesh bag for screening, and the particles that are too large can be kept on the mesh bag for further grinding until it is qualified. "

"Here!"

Lin Jingchun arranged it immediately, and then Su Yonglin ordered to use the flying gun to test the two types of gunpowder after being ignited, and make five pieces of each.

In order to make a comparison, five other flying muskets using traditional gunpowder were also used for experiments.

A total of fifteen flying muskets ignited the leads and protruded out of the hull, followed by a grand fire-breathing scene.

The gunpowder after processing with water and urine is obviously more powerful, not only the eruption distance is longer, but the eruption time is also longer.

The original traditional gunpowder eruption is not so powerful, and there is even a misfire.

And none of the ten flying muskets that processed gunpowder were misfired.

The difference in the eruption of gunpowder with water and urine is not too big. It seems that the eruption with urine is stronger, but there is no obvious difference.

Next, Su Yonglin asked the soldiers to use the processed gunpowder for an eruption test and used up both barrels of gunpowder, which further proved that the performance of the processed gunpowder was more stable.

Lin Jingchun and others looked surprised, feeling that this was a very remarkable achievement.

In the end, Su Yonglin decided to use urine as the best choice for gunpowder processing.

The reason is simple.

You can drink water, but under normal circumstances, no one will drink urine. The human body itself is a natural urine-producing machine. As long as there is water to drink, it can continuously produce urine without interruption.

Therefore, using urine to process gunpowder is really cheap, but Shengjie Army will bear at most one transportation cost.

Although this solution is indeed a bit heavy, but there is nothing wrong with it.

The key is simplicity, cheapness, and the ability to quickly scale up for production, which is the most important thing.

Shengjiejun, who has no money now, needs this kind of low-cost problem solution very much. Only when the cost is low enough can it really come in handy at this time.

Pursuing something tall at this time is purely a bad brain. No matter how powerful a weapon is, as long as it cannot be mass-produced and installed, it will not be of any help to the army in essence.

In the end, it's a question of money.

As for the poor working environment reported by the craftsmen, it is easy to get dizzy, etc., they can only ask them to open the windows for ventilation, take turns to work shifts, and persevere with their own perseverance and perseverance...

Compared with the production cost, the working environment is a very minor issue, not worth mentioning.

After making up their minds, Su Yonglin and Lin Jingchun and the others settled on many details about the processing of gunpowder, and made some rules.

For example, be sure to air dry gunpowder in a cool and ventilated place instead of drying gunpowder in the sun.

For example, when storing gunpowder, it is necessary to do a good job of preventing moisture, and it must not be placed in large-scale gatherings, but should be placed in multiple places.

There are also some details that he can think of are written on paper, so that the craftsmen will keep in mind and abide by the relevant rules.

After thinking about it, Su Yonglin also added a rule.

Any information about gunpowder should not be disclosed to the outside world, and everyone who knows it should keep it tight.

Su Yonglin also formulated a fairly strict "joint sitting" method for this purpose, which is specially used for the staff related to gunpowder.

Lin Jingchun was surprised, but since Su Yonglin showed a harsh side for the first time, it only showed that he was particularly concerned about the issue of gunpowder.

Lin Jingchun did not object and chose to support.

As for the problem of relatively large smoke from the subsequent gunpowder eruption, Su Yonglin felt that there was no way to solve it for the time being.

Before the birth of smokeless gunpowder, there was no solution to this problem, and smokeless gunpowder was already a product of the industrial revolution era.

Just let it go.

All the things that need to be done have been done. While maintaining a considerable scale of intelligence detection and collection, Su Yonglin returned to Tai'an to start the work of digesting prisoners and propagating military prestige.

The prisoners must be digested, the military prestige must be promoted, and there is still a lot of work to be done.

But the end of a war on one battlefield does not mean the end of wars on other battlefields.

In a major war, one or two local battles cannot decide the outcome.

Just because Su Yonglin won, doesn't mean the Restoration Army won.

At the same time when the Battle of Wenshui was over, more than [-] main force of the Jin army were heading towards Yizhou, and the leader was Shu Hu Siji himself.

After Shuhu Siji sent the military document to Jiagu Asu, he couldn't wait to send out troops. The dispatched troops were not 2 as he said, but 3.

Because on the eve of the dispatch of troops, the 1 support troops that Tu Danjing had tried to gather from Damingfu Road finally arrived.

Shuhu Siji was ecstatic, and immediately incorporated the 1 people into the crusade army and announced the march.
