After successfully configuring diatomaceous earth explosives suitable for artillery ammunition bases, mine explosives, grenade dispensing, etc., Xia Lin tried to configure a little smokeless gunpowder.

The so-called smokeless gunpowder is actually cotton wool, and the steps of this kind of thing configuration are quite simple, but it is not easy to get a finished product with high quality and qualified nitrogen content. This method of configuring dangerous goods needs to be mastered by the college students of the Department of Chemical Engineering in Xia Lin's previous life, because its subsequent product is the first plastic in history, that is, Sailulu.

With the help of purification, it is easy to obtain high concentrations of nitric acid and sulfuric acid, in fact, Xia Lin could have tried to configure this gunpowder a long time ago, but at present, the chemical system of the industrial park has only a little foundation, and the output of nitric acid and sulfuric acid is too small, even if this kind of thing is produced in small batches, it will not change the status quo much.

In addition, when used alone, smokeless gunpowder such as cotton wool has the characteristics of being dry and explosive, wet and unusable, and it is quite difficult to preserve, so he has never set out to make it.

Now that the firing process of porcelain has been preliminarily mastered, we can try to establish a simple chemical system to see if we can change the current situation. Although diatomaceous earth explosives are safe and stable, with excellent performance, they are not very suitable for propellant charges.

For gunpowder, explosives and pyrotechnics, many people have a misunderstanding that the more powerful the better, but in fact, according to the different needs of these three types of pyrotechnics, they actually have different characteristics.

For example, gunpowder generally refers to a chemical substance that can burn itself quickly and regularly under appropriate external conditions, and at the same time produce a large amount of high-temperature gas.

Its main use is as a propellant for filling ammunition, although the requirements for the power of this propellant exist, but it is not high, and more attention is paid to the performance of the combustion speed curve, that is, it can complete stable combustion within a certain period of time, and produce enough high-temperature gas to promote the projectile out of the chamber.

The explosive is a chemical substance that can explode or detonate under a certain external stimulus, and the main use of this pyrotechnic agent is to initiate the explosive and the explosive, and the combustion rate curve will grow rapidly in a short period of time, thus producing a large number of high-temperature gases and flames to cause explosions.

As for pyrotechnic powder, it is a pyrotechnic agent that mainly emits light and smoke, and it is mainly used in military smoke bombs, and it is the main charge of fireworks in peacetime.

Among these three types of pyrotechnic agents, the boundaries between the first two are not clear, but diatomaceous earth explosives, which are classified as explosives, are not suitable for use as bullet charges, because the high bore pressure generated by the deflagration of diatomaceous earth explosives can easily damage the barrel of the rifle, causing accidents such as exploding.

Even if it is used in a more durable gun, it needs to be combined with other propellants with a more stable and mild combustion rate to form a so-called bistatic propellant or multi-base propellant. Therefore, this kind of explosives are usually used in the fields of mine explosives, grenades, and explosive packs.

The configuration of fire cotton, which is most suitable for use as a bullet propellant, is also quite simple. ….

Xia Lin repeated more than ten attempts, during which there were four accidental explosions, but fortunately, with the mage armor and the explosion-proof ditch outside the explosion-proof laboratory, he had always been safe and sound, and after these difficulties, he finally got a batch of products that met the requirements.

From the outside, the cotton wool is just an ordinary lump of cotton with a slight yellowing, and no one would think that these things will be a dangerous goods at first glance, but Xia Lin knows the danger of this kind of thing that has a lot to do with nitro, so he carefully sandwiched these cotton wool into the ethanol solution produced by the distillery, and then covered the lid of the clay pot, and then coated a layer of water glass in the gap for sealing and fire prevention.

Accomplishing the purpose of his trip, Charlin took these two things to the Gun Factory to find Master Faun, and asked them to bring a batch of brass shells and bullet casings, and began to load them.

The projectile can be mixed with diatomaceous earth explosives and fire wool, which is also the simplest bi-base projectile, and the bullet can be made with camphor, a stabilizer, with a slightly treated fire wool.

After the loading of these two types of shells, it is natural to test the power

The 2A rifle produced by the gun factory during this period of time was filled with eight rounds of brass shell cotton propellant through the magazine, and for the sake of safety, Xia Lin let people use the original simple long-range firing mechanism.

"Ready! Let's go!"

As the starter's arm holding the bright red flag fell, the tester pulled the rope and triggered the trigger of the Type 2A rifle, "Peng!" With a loud bang, the Type 2A, which was tightly tied to the gun mount, trembled, and the target in the distance fell.

A tester stepped forward to straighten the gun carriage, calibrated the muzzle of the rifle to aim, and then fired again, and after eight successive fires, the Model 2A finally stopped.

"Wait!"

Xia Lin stopped the tester from continuing the experiment, and stepped forward to take Master Faun and several of his young human apprentices to check on the 2A rifle.

Fortunately, after this period of production, the steel mill has initially mastered the method of controlling the composition and quality of the steel output by allocating raw materials, and the quantity and quality of the steel supply that the gun factory can obtain during this period have improved a lot, otherwise Xia Lin is really worried that the Type 2A rifle will not be able to withstand the impact of this copper-shelled bullet that uses fire cotton as a charge.

"Boss, this gunpowder is strong enough!"

Master Faun touched the barrel of the gun, which was already hot, and looked at the target that was set at a position of two hundred or even three hundred meters in the distance, but he was still hit and exclaimed.

"This projectile is more than just powerful, Master Faun, don't you see that it has a unique advantage?"

Xia Lin reminded with a smile at Master Faun's compliment.

"Another advantage?"

Master Faun took out a brass flask and took a sip of rum, and after thinking for a while and finding no problem, he suddenly showed a look of surprise and confusion, and had to scratch his head and say with some embarrassment:

"I'm stupid, boss, don't sell it, what advantage are you talking about?"

"The advantage is that when this gunpowder is fired, there is no smoke and there is very little residue left in its combustion! In other words, in the past, our rifles had to be cleaned with a cleaning rune disk after firing a dozen or dozens of rounds each time, but now we don't have to think about this problem at all, and the same is true for artillery!"

Seeing this, Xia Lin stopped being a riddler, and said a phenomenon that Master Faun and the others had just overtaken the range and power of the rifle that used this new type of ammunition.
