Since the explosion effect was not too satisfactory, Zhong Hao took a few craftsmen to improve it. Pen ~ fun ~ pavilion www.biquge.info

When saltpeter, sulfur and charcoal are milled, the grinding is more fine; When weighing these three ingredients, the weighing is more accurate and careful, and the iron can is sealed more tightly; When the gunpowder is filled, the filled gunpowder is pounded more strongly; Anyway, Zhong Hao and a few craftsmen thought of the areas that could be improved, and tried to improve them as much as possible, so as to make them more perfect.

It can be followed by several trials, but it is still not too satisfactory.

Zhong Hao couldn't help but have some doubts about his memory, could it be that he remembered it wrong. But if you think about it, it should be right.

The weight ratio of saltpeter, sulfur, and charcoal is fifteen to two to three, which is actually 75 catties of saltpeter powder, 10 catties of sulfur, and 15 catties of charcoal in 100 catties of gunpowder, which is a relatively easy ratio to count. Zhong Hao felt that it was impossible for him to be mistaken.

After thinking about it carefully, Zhong Hao suddenly remembered one thing, the saltpeter used in black ~ gunpowder in later generations should actually refer to potassium nitrate crystals. And the saltpeter of this era is generally earth nitrate. The nitrate fifteen in the weight ratio of fifteen to two to three should be the weight of potassium nitrate crystals, not the weight of earth nitrate.

Zhong Hao's later generations knew that soil nitrate was actually sodium nitrate and calcium nitrate. The method of obtaining potassium nitrate crystals with soil saltpeter is actually very simple, mixing soil nitrate with plant ash to dissolve water, and constantly heating, stirring until saturated dissolution, filtration, cooling, you can precipitate the crystal is potassium nitrate. It's just that this method is still unknown in the Great Song Dynasty.

At that moment, Zhong Hao immediately found a hidden place and took matters into his own hands to extract potassium nitrate with soil nitrate.

After extracting the potassium nitrate crystals, he made some black ~ gunpowder again in the ratio of the weight of saltpeter, sulfur, and charcoal to fifteen to two to three, and Zhong Hao took a little more to test again.

The effect of this blasting is much better than the last time, the small iron can containing gunpowder was blown apart this time, Zhong Hao was very excited, it seems that this ratio is no problem.

After this test, Zhong Hao tried it again, and the dosage of this second test was much larger. Of course, for the sake of safety, this large-dose blasting, Zhong Hao deliberately asked the craftsman to make the velvet lead very long, and after lighting the lead, Zhong Hao ran away and quickly ran behind the cover made in advance.

The sound of the explosion was very loud, and the impact of the air wave of the explosion was also very strong, and Zhong Hao felt the vibration of the air around him behind the bunker.

However, Zhong Hao did not add those iron nails and thistles to the iron can, and what scattered with the explosion was just the iron sheet of the iron can. Zhong Hao felt that the effect of gunpowder made in this ratio was still good.

Zhong Hao only cared about the gunpowder test, and forgot a very important thing, he forgot that horses are very sensitive to sound, and they are most afraid of loud things. Although the war horses of Jingqiang Village have undergone a certain amount of training and are accustomed to the sound of fighting, bells and drums in the battlefield environment, they have never been trained for the sound of huge explosions.

The movement of this gunpowder explosion test was too great, which frightened the war horses of Jingqiang Village. Fortunately, Yang Huaiyu and several Yang tutors controlled it in time, so they avoided the tragedy of the startled horse and camp.

Yang Huaiyu has always regarded Zhong Hao as a big brother, and he has always respected Zhong Hao, but this time he came to Zhong Hao with a fierce attitude, looking like he couldn't wait to eat Zhong Hao, and he opened his mouth to count Zhong Hao out loud.

Zhong Hao knew that he was at a loss this time, so he had to let Yang Huaiyu count down, and repeatedly promised that he would test a large dose of gunpowder explosion test in the future, and he would definitely not test it near Jingqiang Village again, so as not to cause shock.

Zhong Hao's good attitude was effected, Yang Huaiyu saw Zhong Hao's attitude like this, his anger quickly subsided, and he returned to the previous playful face of the son of the family, and said with a smile: "Big brother, this is studying gunpowder, right?" ”

"yes, yes."

Yang Huaiyu suddenly leaned over and said with a flattering smile: "The power of this gunpowder developed by my eldest brother is not small, can you give me some for the Western Army of Linzhou Town!" Yang Huaiyu still admires his brother Zhong very much, he doesn't know where he got the soju, potatoes and other things, but they are definitely good things. The explosion of gunpowder was so loud that it must have been a good thing. Potato Yang Huaiyu has already asked Zhong Hao for it, and Zhong Hao has promised to harvest it next year and give Linzhou some seeds. Yang Huaiyu felt that this gunpowder was also a good thing, and he couldn't help but ask for it at the moment.

Zhong Hao felt that the gunpowder formula he developed could not be easily told to others, after all, this gunpowder was a strange commodity, but gunpowder could still be given.

After all, now the relationship between the Yang family and himself is good, Yang Huaiyu is also very concerned about the cavalry training of his Jingqiang Village, and the Yang family caravan is also very sincere in cooperating with him.

Although the production of these gunpowders was made by those old craftsmen, they naturally knew the proportion of the gunpowder formula. But Zhong Hao felt that these old craftsmen were all old people from the Pingxi Army, they were military members, and they dragged their families with them, so they shouldn't easily leak the formula. After all, the generals of an army have a way to rectify their subordinates. Although Zhong Hao is not yet the general of the Pingxi Army, he is now more authoritative and prestigious than their previous general for the Pingxi Army. Without Zhong Hao, they were still struggling in Hedong in another country.

Of course, even if this old craftsman leaked Zhong Hao's newly developed gunpowder formula, Zhong Hao was not afraid. Zhong Hao did not tell them the method of refining potassium nitrate from soil nitrate in order to keep it secret, but personally mastered and extracted it himself.

Zhong Hao smiled at Yang Huaiyu and said: "This gunpowder is not of much use to you now, you can use it to set fire at most, and when I study how to use this powerful gunpowder to make a suitable firearm, it is naturally indispensable for your Zhenxi Army!" ”

Yang Huaiyu arched his hand at Zhong Hao, smiled excitedly, and said: "Then the little brother thanked Brother Zhong first, and he knew that Brother Zhong was generous!" ”

The reason why Zhong Hao said that the gunpowder for the Zhenxi Army now has little effect is because the gunpowder weapons of the Great Song Dynasty today are mainly used to make several simple tactical weapons such as incention, poison gas, smoke screens, etc., and will not make firearms that kill and injure the enemy by explosive power.

Today's Yin Zeng Gongliang of Kaifeng Mansion of the Great Song Dynasty, in the book "General Essentials of the Martial Arts" compiled during the Qingli period, described in detail the production process and use methods of more than a dozen weapons such as rockets, artillery, gunpowder whips and arrows, fireballs, tribulus fireballs, iron-billed fire harriers, bamboo fire harriers, thunderbolt fireballs, smoke balls, poison smoke balls, etc. Various weapons are made in different ways, with different uses and tactical purposes.

During this period, gunpowder weapons were mainly used to create smoke screens, poison gas, burning, tear gas, sneezing, stunning, and other various tactical functions.

There were more than a dozen gunpowder weapons for different purposes in the Great Song Dynasty, but none of these weapons relied on the explosive power of gunpowder to kill and injure the enemy.

In fact, Zhong Hao also knew that it was not that the Great Song Dynasty did not want to develop weapons that relied on explosions to kill and injure the enemy, but that the performance of gunpowder in this era was limited, and it was difficult to create weapons that relied on explosive power to kill and injure the enemy.

The lethal power of firearms mainly depends on the scientific and rational formula of gunpowder and the performance of gunpowder, followed by the improvement and perfection of the firing and triggering mechanism.

Although gunpowder has developed a lot at this time in the Song Dynasty, its prescription has not yet been strictly quantitatively proportioned, the raw material composition is complex, and the purity is not enough, so it still cannot effectively exert the full performance of gunpowder. So it is not surprising that gunpowder weapons at this time were only used to make weapons to support combustion and release poison gas and smoke screens.

Zhong Hao asked people to buy the "General Essentials of the Martial Arts", and he also read it in detail, and the "General Essentials of the Martial Arts" has a detailed discussion of the performance, production and use of various weapons. For example, gunpowder is also recorded in detail, and the ratio of gunpowder in this era is still very complicated, such as gunpowder with 14 kinds of ingredients, and there are 10 kinds of tribulus gunpowder. Not only are the various ingredients recorded, but even the detailed proportions are also recorded.

The literati of the Song Dynasty were good at writing books and said, and if they wanted to leave a name in the world, Zhong Hao could understand. But Zhong Hao really couldn't understand how such a major military matter as weapon manufacturing could be used in a book to talk about it? Isn't something like gunpowder supposed to be a secret? I took it to write a book and said it, for fear that the Xia people and the Khitan people would not be able to learn it, or how?!

Zhong Hao felt that his gunpowder formula must not be known to outsiders, especially Zeng Gongliang. It is said that Zeng Gongliang has a good relationship with his future Taishan boss, and he must be guarded against in the future. Otherwise, it is estimated that Zeng Gongliang's urine sex is estimated to be spread soon.

The gunpowder weapons of the Great Song Dynasty today do not have an explosive power to cause damage, because of the limitations of gunpowder performance, but they have gunpowder with great power. Zhong Hao felt that he should develop a weapon that relied on explosions to kill and use the gunpowder he developed to fuel combustion, release poison gas and smoke screens, etc., which was too much of a waste of his powerful gunpowder.

Grenades and mines are good choices, and it should not be difficult to develop, of course, the simplest explosive and anti-personnel weapons are also indispensable.

However, when Zhong Hao really started to start researching, he found that the basic conditions are too weak today, and many things are difficult to realize.

Under the research of a group of blacksmiths, it was not easy to make a cast iron shell that was easy to explode and could be used to make grenades, but the trigger device that detonated the gunpowder weapon made Zhong Hao glare.

The kind of trigger detonation devices such as delay trigger devices, impact trigger devices, and flintlock trigger devices in later generations are not available, and it is difficult to make them, and Zhong Hao is also powerless for the time being.

Zhong Hao had no choice but to temporarily detonate the grenade by using a simple velvet fuse ignition.

The impact trigger device and the flintlock trigger device, Zhong Hao felt that it was still possible to solve it with more research in the future, but it could not be solved for the time being, and there was no need to study the mine, which is a weapon that is mainly triggered by impact.

Zhong Hao and the old craftsmen concentrated their efforts on testing grenades, which are explosive and lethal weapons.

The cast iron shell that was relatively easy to explode was loaded with gunpowder, filled with iron sand, iron nails, tribulus terrestris and other lethal materials, and a small hole was left on the top to install a lead, and a simple ignition triggered, which can be called a grenade, was born.

Zhong Hao looked at this iron-clad weapon, although it looked extremely ugly, but he still had a lot of expectations for it in his heart.

Zhong Hao found a test site outside Jingqiang Village, far away from the training ground of the war barracks.

Zhong Hao lit the velvet at the top of the grenade in the pre-prepared bunker, threw it out with all his might, and immediately lay down in the bunker with those old craftsmen.

After waiting for a long time, I heard a muffled sound.

After the muffled sound, Zhong Hao and the old craftsmen climbed out of the bunker and stepped forward to check.

The effect of the explosion of the iron shell was not ideal, it only blew a hole, and did not fall apart. However, the impact of the explosion was still not small, and the surrounding straw people were torn apart by the air wave of the explosion.

"The iron shell needs to be cast thinner by those blacksmiths, and the velvet lead should be shortened by an inch!" Zhong Hao looked at the effect of the explosion and said to a few old craftsmen.

The old craftsmen wrote them down one by one.

Zhong Hao also told a few old craftsmen about some of the skills of making granular gunpowder, and asked them to make some together.

Granular black powder came into being after the emergence of a large number of tubular firing weapons such as fire control.

Because gunpowder is made into granules, there is enough air between the particles to make the gunpowder burn more fully in the event of an explosion. In addition, the fire spreads on the surface of the granular gunpowder, which greatly increases the rate of gunpowder burning, and obtains greater power by reducing the reaction time. The power of gunpowder increases, which can increase thrust and improve hits.

Moreover, the use of granular gunpowder will greatly reduce the residue in the gun boring, the reliability of the gun will be greatly improved, the blockage may be reduced, the time spent on cleaning the gun boring will be reduced, and the granular gunpowder filling speed will be faster. This greatly increased the rate of fire.

Of course, Zhong Hao is not in a position to manufacture shooting weapons such as fire control for the time being, but it is still useful to develop granular gunpowder. Even if a grenade uses granulated gunpowder, it can greatly enhance the power of the explosion.

And most of the gunpowder at this time was contained in wooden barrels. Even if the powder gunpowder is fully crushed, it is impossible for the raw materials and microparticles to be the same size. The powdered gunpowder is constantly shaking in the confined space of the wooden barrel, and the large particles in these solid mixtures will rise, and the small particles will sink, and when it is used, it will cause the composition ratio to be inaccurate, and it is difficult to exert its maximum explosive effect.

Sulphur is often deposited at the bottom of the barrel after long hauling, and it is necessary to stir it again before use, otherwise it will greatly affect the power, and the granular gunpowder greatly reduces this trouble.

Powder gunpowder has these drawbacks, and granular gunpowder making is not too difficult to do. Zhong Hao felt that since there was a way to make gunpowder more powerful, he naturally had to study and test it.

In fact, it is simple to make granular gunpowder, which is to mix gunpowder with water and a part of the binder and press it into a cake, and then mash it to make granules and dry. Of course, it requires a lot of attention to the points that need to be paid attention to, and it is also a job that requires water grinding. There is nothing wrong with putting more effort into gunpowder, and the more elaborate this kind of thing is, the more powerful it will naturally be. (To be continued.) )
