God knows what sensitive words there are, and it took at least three hours to send them!!

……………………

Lu Zhe's research on gunpowder is not a day or two, but a full six years!

Although gunpowder is called gunpowder, but the power produced by different ingredients is absolutely different, many times Lu Zhe wonders why the same is the same peer who crosses, others can easily make explosive gunpowder, and he tosses and tosses only to produce some flammable, flammable and then exploding but not much explosive gunpowder.

Gunpowder is indeed called gunpowder, but its composition is different power, some gunpowder can only be burned, can also produce explosions, but the power can only provide a sound, can not provide military needs.

As long as you know a little bit of chemistry, you can understand one thing, there are many variations in the formula of gunpowder with different functions. It's all gunpowder, but some gunpowder can only be used to make artillery shots, and some gunpowder is explosive enough to assemble warheads.

Bronze metal still has a variety of forms, different composition of the element table, the matching elements will make the bronze hardness change, the color will also appear different reactions, then iron and steel must also be a general term, iron and steel also have their own element table, different formulas can also make the density of iron or steel different.

The components of gunpowder are nitrate, sulfur, and charcoal, so how much nitrate, how much sulfur, and how much charcoal should be?

Gunpowder should be in powder, granular, and ball shape...... Or what does it look like?

The gunpowder developed by the empire before was not that there was no impetus after the explosion, but that the impetus generated by the lack of explosiveness was pitiful, and the ejection force was only to push the projectile out of the barrel. The speed of the projectile leaving the barrel is difficult to observe with today's technology, but the distance that the projectile can fly is only less than 70 meters, and after more than 50 meters, it is no longer very lethal, and it is difficult to shoot through armor at a distance of 20 meters.

Oh. Under Lu Zhe's intervention, the appearance of firearms is not surprising, and it is an epoch-making product when it appears, a flintlock pistol with a steel barrel, which is an extremely extravagant thing, and the original historical flintlock pistol used wrought iron.

Weird, right? Firearms are more advanced than gunpowder. But there is absolutely nothing surprising about this. According to popular parlance, it was a product of a different development direction of the tech tree, and the empire was developing metal materials faster than others.

In fact, it is not surprising that the development of metal materials is advanced, and it is inevitable that the research of metal materials is better than other things in history, because many aspects need to use metals. If there is a demand, it will inevitably be valued, but other things are new discoveries or unexpected products of experiments, so what is it strange that one aspect is advanced and other aspects are blank?

The Imperial military was already using gunpowder, such as the flares used by the stragglers. Another use of gunpowder by the military was to raise fire quickly. In fact, the army has long been using chemicals, such as sulfur is an indispensable fire tool for the army, as early as the Spring and Autumn Period and the Warring States Period, they found that placing sulfur in the firewood pile can quickly raise the fire, so it is also used.

“…… The proportions are 75 percent nitrate, 10 percent sulfur, 15 percent charcoal and 80 percent nitrate, 10 percent sulfur, and 10 percent carbon. ”

Listening to the report, Lu Zhe wanted to give his head a moment, he didn't remember that there was a relevant record of the Raven Pills War, and it seemed that there was a special explanation of the gunpowder ratio between the British army and "I Daqing". It has talked about the effect of gunpowder components on the thrust of firearms, and also emphasized that the moisture caused by the gunpowder formulas of both sides is a loss for the "I Daqing" side.

But then again. Human beings are biological heads, although the eyes have been capturing pictures and storing them by the cranial nerves, but many times people subconsciously "excrete" information that they think is useless, so it is normal to forget what they are experiencing and then remember.

"We've been working on gunpowder granules for a long time, and the progress of the research is very fast after the direction is given. The above two gunpowders were processed in granular form, and the No. 3 workshop on the south bank of the Yangtze River exploded when it was improperly stored during particle processing. ”

Xiao He couldn't tell what improper storage was, his understanding of gunpowder was not even skin, he didn't understand the natural chemical reaction of gunpowder in hot weather, and he didn't understand what it was like to store gunpowder in bulk and clay pots. Then there is a trace of spark outside, that is, Mars hits the earth, and after a "boom", the entire workshop is razed to the ground, and the people at the center of the explosion are so dead that they can't even find the bones and slag.

"Under the series of explosions, a large crater with a diameter of about 30 meters appeared at the center of the explosion, which was also affected within a radius of three miles, and the number of missing people in the workshop was 23, 189 people died, 321 people were seriously injured, and 1,404 people were slightly injured. The storehouse of Workshop 3 was razed to the ground, and the rest was in shambles. After the explosion, the surrounding woods were set on fire by sparks, and the city defense forces have been ordered to extinguish the fire, and the fire has been brought under control. ”

The No. 3 gunpowder workshop was indeed placed on the edge of the forest, and it was located relatively close to the Yangtze River, but it was convenient for transportation. It is precisely because it is located not far from the south bank of the Yangtze River that the loud noise at the time of the crash made almost the entire Nanling Tomb hear the loud noise, and half of the Nanling Tomb could also feel the obvious tremor.

"How much gunpowder exploded?"

"Back to the king, there are statistics that 1,400 catties of granular gunpowder have been completed, and 37,000 catties of unprocessed gunpowder have been completed......"

"You can't use clay pots anymore, absolutely no more clay pots. Wooden boxes, paper bags, fully use wooden boxes and paper for transportation and packaging, don't use clay pots anymore! ”

God, a clay pot is equipped with gunpowder, especially a qualified black powder that already has a strong chemical properties, and that sealed clay pot is a large hand grenade, and exploding is definitely two different consequences from gunpowder without sealing. Sealed gunpowder is an instantaneous explosive nature, and gunpowder that is not sealed is an incendiary nature, and the consequences of explosion and combustion will never be the same.

"This ...... The rainy season in the south is more than that, and it is because of the moisture resistance that clay pots are used. If you use wooden boxes and paper, I may ...... when the rainy season comes."

"I don't want to say it a second time."

"This ...... Promise. It's just that each workshop needs to allocate special funds for the construction of the roof. The size of the workshops varied, and if it was necessary to fully roof it, it was not only a financial use, but we had no other means to process the gunpowder after the sun was exposed. ”

Yes, the processing of gunpowder does require sun exposure, after all, it is not modern or modern now, even if it is known that gunpowder can be dried. However, it is difficult to ensure the temperature control in the drying process, if it is really used for manual drying, will there be several explosions in the drying process, will it make the gunpowder being dried burn directly, will it ...... Countless will not, only God knows what will happen.

"Southern Rainy Season ......"

"Yes, the rainy season in the south. In fact, the gunpowder workshop should be located in the northwest or the Central Plains, the rainy season in the Yangtze River basin and the south is longer, and the humidity of the air is heavier in some seasons. Not very suitable as a gunpowder production base. ”

"There are difficulties to overcome, how is it possible to place gunpowder workshops in those areas now."

"That's true."

The words are saying that, but Xiao He really doesn't know why Lu Zhe attaches so much importance to gunpowder, not only does Xiao He not understand, but there are definitely not many people who can understand why Lu Zhe attaches importance to gunpowder today.

It is always a small number of pioneers who are pioneers, and the actions of those pioneers are often not understood or fully accepted by the world, as was the case in the Middle Ages in the West. Countless pioneers of science were regarded as heretics, and were either arrested and tied to the ten~character ~ rack and burned to death, or directly hacked to death by the Sect~Religious Inquisition.

In some ways, Lu Zhe was also a pioneer of the era. The only difference between him and those who were burned and hacked to death was in his background and identity. When the ruler of a country wants to conduct research in a certain direction, he not only has sufficient funds to mobilize anyone who wants to be mobilized, but no one will jump out to burn or kill. With absolute power, he didn't have self-control to kill whoever he wanted to kill.

"Workshop 3 is destroyed, and we only have nine workshops left. The ministers have issued orders to the various places to disperse the gunpowder storage sites, and have also ordered them to strictly ensure safety. The king wanted to use wooden boxes and paper for loading and packing. It takes a certain amount of time, the time to make the wooden box, and the paper also needs to be transferred and transported. We also don't have a mature wooden box and paper packaging solution, ...... you see? ”

"Brainstorm ideas from the crowd and send out a reward for effective solutions."

"Understood. Other than that. We have planned twenty-eight artillery and rifle workshops that you value, of which eight artillery workshops have been established and only two rifles, but there are some new problems. ”

"Huh? Say! ”

"The master craftsmen found that wrought iron could replace steel, and that the barrel made of wrought iron was in some ways more stable than steel, and that the cost could be saved by at least 40%. In the selection of artillery materials, the master craftsmen believed that bronze was the most suitable metal. ”

"Wrought iron? Isn't the problem of burrs and rust in cast iron yet fruitful? ”

What is wrought iron? What is the so-called cast iron? In fact, it is definitely not as simple as it seems, and it also includes the use of iron, carbon and silicon elements to form alloys, and then the literal "forging" and "casting" techniques.

After the emergence of the waterwheel, the empire has actually matured the use of water power on the Yangtze River, such as the use of water power borrowed from the factory to make money, so it will naturally not let go of the production of iron and steel, but it is generally used in processing.

The development of water conservancy in the Yangtze River basin has led to the emergence of countless workshops and factories on both sides of the Yangtze River, and the resonance of various machines that should not have appeared until after 1800 has also appeared in 211 BC, at least 2,000 years in advance!

Lü Zhe is building a powerful empire, and it is the military that takes the lead in building a powerful empire with the advantage of population, which is in line with the development trend that all advanced products must be the first to be applied to the military. The expansion of the Imperial army has reached a peak, and it is no longer enough population to drive the demand for development, and the test of expansion has tended to be whether there is enough local productivity to provide the army with war materials.

It is difficult to promote the development of relying entirely on relatively primitive manual work to increase productivity, and the use of machinery has been put to the peak of demand. Premise of need, as a primate creature...... That is, people with superior intelligence and creative thinking, they will find ways to explore the progress of productivity, and then all kinds of machines will be built.

Gunpowder reached the expected goal, after having qualified gunpowder, Lu Zhe was not a pure "ancient", he would not think that gunpowder could only be used to make fireworks, let alone that gunpowder was only used to package and then ignite to listen to a sound, and use gunpowder to make firecrackers to contribute to the promotion of the festive culture of the people. The reason why he studied gunpowder in every possible way was to use it to kill people, to kill many, many people!

Xiao He's so-called rifle is a flintlock pistol, which is completely a product of Lu Zhe's handwriting.

Lu Zhe is a man, isn't he? He's still a normal man!

Any man living in the age of the Internet will most likely not pay attention to how gunpowder is made, but at least half of the men in a hundred will be curious to look up firearms on the Internet, first automatic firearms, then semi-automatic, and as the interest grows higher, they will definitely learn about antiques such as arquebuses and flintlock pistols.

It's normal and a bit of a coincidence, Lu Zhe ...... for some reason Well, in fact, it is some things about arguing with people about flintlock pistols, and he has studied them very thoroughly, and in order to win the arguments, he has thoroughly understood the structure of the flintlock pistol.

During the research and finalization of the flintlock pistol, Lu Zhe definitely did not make a qualified flintlock pistol for the first time, but he couldn't bear to make it repeatedly, and if he was wrong, he would repeat it, until he made a flintlock pistol that he thought was qualified, and then an epoch-making product appeared.

Before, the gunpowder was unqualified, even if it could make a qualified or sophisticated flintlock pistol, but it was useless, and it was not the same until the gunpowder was qualified, a flintlock pistol with a range of about 200 meters was actually not better than a crossbow, but it was at least a gun.

In fact, Lu Zhe also knows that the development of firearms is not urgent, compared to firearms with complex structures, artillery is even relatively simple, so he wisely put artillery into the first production sequence, rifles are only produced in small quantities, but the research on rifles should be strengthened again and again, if you can study smoothbore guns and rifled guns after the process is mature, whether it is front-loading or rear-loading, he has enough patience to wait!
