Of course, it’s also high, and there is a wenshui beside it.
Besides water, the minimum amount of liquid can be obtained …
That’s urine, right?
Thinking of Su Yonglin in this way, I suddenly feel that it is possible to pee except water. It seems that there are quite a lot of places, such as children’s urine …
Anyway, it doesn’t matter if you try it a little. There is absolutely no shortage of this kind of thing in the military camp
So Su Yonglin touched Ba Hu’s mouth slowly.
"In this case, try to wet the gunpowder into a paste, stir it well, then dry it, and then grind it back to gunpowder, which may solve this problem."
They looked at each other and then looked at Lin Jingchun together.
Lin Jingchun’s face is reluctant.
"Will this do? Water and gunpowder? "
"Try it, try it, and then try to pee."
"urine?"
Lin Jingchun was even more surprised.
"This is also a multi-faceted consideration."
Su Yonglin’s hands spread out. "Gunpowder is not limited. If we succeed in the experiment and can solve this problem, we have to engage in large-scale money-demanding and a lot of money. Can we afford it now?
Besides water and urine, what can save money more? Shall we drink? Or cow’s milk and goat’s milk? Or are those rich businessmen only able to afford drinks? Which can we afford except water and urine? "
A group of people, you look at me, I look at you.
Lin Jingchun bowed their heads and thought for a while, and finally had to nod at the financial situation of Victory Army.
Su Yonglin’s treatment for the army is higher than that of this era. Most of the troops can make it alone by investing three meals a day, not to mention other troops.
For example, investment in meat and education is a lot of money.
Pay is paid in full and on time every month. Su Yonglin personally sent someone to supervise the payment of pay directly to every soldier, and never defaulted.
In addition, Su Yonglin will also spend money to subsidize military farmers and give some administrative subsidies to the workers of farmers’ associations in the new countryside, all of which must be spent.
Adding all kinds of other weapons to the miners’ salary expenses and all kinds of employees’ salary expenses made the Victory Army’s finance not plentiful.
There is only so much money that can be invested in new weapons research. It is really necessary to toss out new weapons, and we must consider where to squeeze money out and invest it to make new weapons.
It’s not that I can’t understand Su Yonglin’s concerns when I think about Lin Jingchun like this.
"So … is really great."
Su Yonglin then clapped his hands.
"Right? Water and urine are the most economical. If we succeed in solving the gunpowder problem, it will be better. Then we can try to improve his firearms. If it doesn’t work, we won’t spend too much money."
Lin Jingchun agreed with Su Yonglin’s concept of saving money. He nodded again and again, and then there was another problem.
"This problem aside is the problem of gunpowder manufacturing. A Lang, we have found some craftsmen who can make gunpowder, but it is difficult to obtain nitrate in raw materials.
Now those craftsmen drill into toilets and pigsty every day to scrape some nitrate at the bottom of those walls, but to be honest, they don’t get much, and they really need to increase their manpower. "
Su Yonglin frowned for a moment and then nodded.
"If necessary, we can increase some manpower for them or inform the farmers’ association to mobilize farmers to scrape nitrate from their own latrines and pigsty, and give it to the arsenal, which can give copper coins or some food rewards."
Lin Jingchun also agreed after listening to it.
"I think so, too. It’s definitely faster to get everyone to do it together than to run around scraping."
With this, Lin Jingchun thought of another question. "But even in A Lang, we can’t make much gunpowder. If gunpowder really gets up, it will be finished soon after it is seized from the gold thief. We should prepare early."
Chapter 119 Heavy Taste Solution
Technical problems are reliably solved by investing money, but the problem of obtaining raw materials depends not only on technology but also on geographical location
There is no mineral land, that is, if there is no God, you can’t dig three feet without food.
So this is indeed a problem.
If you want to develop the basic raw material of firearms, gunpowder must always be guaranteed.
However, there is no stable output of nitrate ore, and it can’t boil much nitrate by scraping it around in toilets and pigsty.
Among the components of gunpowder, nitrate accounts for the largest, largest and irreplaceable proportion, and Su Yonglin remembers that it seems to be 70%.
At present, the largest recoverable saltpeter mine is located in Hanzhong and Shuzhong, which are thousands of miles away from Shandong, so it is not necessary to consider it.
It is an alternative to produce soil nitrate in Shandong and surrounding areas, such as Cao Zhou and Danzhou.
But Cao Zhou and Danzhou Eye are not controlled by Su Yonglin.
So Su Yonglin is faced with a very embarrassing problem-no saltpeter mine can collect saltpeter from latrines and pigsty to boil.
This will definitely not last long, and Su Yonglin also has an idea about when the time is ripe to take Cao Zhou and Danzhou, so that a stable gunpowder workshop can be built.
Without a stable gunpowder workshop, it is difficult to develop firearms.
However, Su Yonglin, who belongs to Nanjing Road in Cao Zhou and Danzhou, can only reach Cao Zhou and Danzhou through Dongping Prefecture and Jeju.
Well, this is a question worth thinking about.
Although it is worth thinking about, it is not the most important problem, and it can be delayed.
Lin Jingchun, however, was a strong man with strong mobility. After Su Yonglin’s instructions, he immediately took a bucket of water and a bucket of urine and made the soldiers of the logistics unit start to improve the gunpowder.
Add water or urine to the ready-made gunpowder and stir it into a thick paste. Don’t add too much water and urine at one time, but add it in stages.
After the viscous powder paste is finished, knead them into cakes and put them in a ventilated and cool place to air dry, and then grind them again after they are air-dried and hardened.
Thus, it may be possible to obtain gunpowder with stable properties.
Then see if it is better to add water or urine, or neither.
That would be a headache.
There is nothing easier to obtain low-grade liquid than water and urine.
The gunpowder here is air-dried and Li Shi’s work there is also in rapid progress. Liu Xi worked very hard to survive and get recognition. In just three days, he almost cleared a navigable channel.
Therefore, the Victory Army finally captured the war profits through the great war, but it could also be taken away by tugboat and then returned to Taian to strengthen itself.
On the ninth day of July, Su Yonglin stepped on the road of returning to Li, and the victorious army officially triumphed.
Su Yonglin, a ship on the Li Road, personally observed the air-drying and regrinding gunpowder.
He found that after adding water and urine, the air-dried grinding powder was more stable than before, and it was not separated by itself when it was shaken in a bucket for a while.
Squeeze a handful and watch carefully, and you will find small powder particles of different sizes, which means that at least powder granulation has been realized.
That’s interesting
But that’s not enough
"Powder particles can’t be too big. Make a small mesh bag. Keep the mesh size constant. Put the ground powder into the mesh bag for screening. If the particles are too big, you can leave the mesh bag for further grinding until it is qualified."
"hey!"
Lin Jingchun immediately arranged to go, and then Su Yonglin asked the flying musket to test the fire-breathing situation of two kinds of gunpowder after ignition, and each made five.
In order to make a comparison, five other flying muskets were used for experiments.
A total of fifteen muskets lit the fuse and then extended out of the hull, followed by a grand fire scene.
After the water and urine are processed, the powder is obviously more energetic when it erupts, not only because it erupts farther, but also because it erupts longer.
The original gunpowder eruption was not so powerful, and there was even a dumb fire.
And processing gunpowder, ten flying guns and one misfire.
Compared with the gunpowder eruption with water and urine, the difference is not very big. It seems that the gunpowder eruption with urine is stronger, but there is no obvious difference.
Then Su Yonglin asked the soldiers to take the processed gunpowder for eruption test, and both barrels of gunpowder were exposed, which further proved that the performance of the processed gunpowder was more stable.
Lin Jingchun and others looked surprised and felt that this was a very great achievement.
Finally, Su Yonglin decided to choose the best choice for urine powder processing.
