"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 and said, "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, it is not necessary to consider that Hanzhong and Shuzhong, which are the largest saltpeter mines that can be mined, are thousands of miles away from Shandong.
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 started to act. Soon, he collected a bucket of water and a bucket of urine, which made the soldiers of the logistics unit start to improve their 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 re-grinding of gunpowder after air drying.
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.
The reason is quite simple
Water can still be drunk, but under normal circumstances, no one will drink urine. The human body is a natural urine-producing machine. If you have water to drink, you can continuously produce urine.
It’s really cheap to process gunpowder with urine, but Victory Army can undertake at most one transportation.
Although this solution is a bit heavy, there is nothing wrong with it.
The key is simple and cheap, which can quickly form a production scale, which is the most important thing.
At present, there is nothing that Qian Shengjie really needs. The solution to this low-cost problem is low enough to really send a field at this time.
At this time, it is purely a bad brain to pursue what is tall. No matter how powerful the weapon is, it will not be of qualitative help to the army if it can not be mass-produced and installed.
In the final analysis, it is still a matter of money.
When craftsmen report that the working environment is bad and they are prone to dizziness, they can also ask them to open the window for ventilation and take turns to change shifts, and they will persevere and persevere …
Compared with production, what is really a very small problem in the working environment is not worth mentioning.
After making up his mind, Su Yonglin and Lin Jingchun decided on many details of processing gunpowder and made some regulations.
For example, it is necessary to dry gunpowder in a cool and ventilated place instead of drying gunpowder in the sun.
For example, gunpowder needs to be well protected from moisture, and it must not be placed in large quantities, but in multiple places.
There are also some details that he can think of, which are written on paper for craftsmen to remember and abide by the rules of phase.
After thinking about it, Su Yonglin also added a rule.
No gunpowder information can be revealed to the outside world. Everyone who knows it should keep his mouth shut. If information is found to be leaked, it will be regarded as a violation of military law at your own risk.
Su Yonglin also formulated a very strict "sitting together" law specifically for gunpowder workers.
Lin Jingchun was surprised, but since Su Yonglin showed a harsh side for the first time, he could say that he was particularly interested in gunpowder.
Lin Jingchun then chose support without objection.
Su Yonglin felt that there was no way to solve the problem of large smoke caused by gunpowder eruption for the time being.
