Chapter 276 Ammunition Test

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

The so-called smokeless gunpowder is actually gun cotton. The steps to configure this kind of thing are relatively simple, but it is not easy to obtain a high-quality and qualified finished product with nitrogen content.This method of disposing dangerous goods must be mastered by Xia Lin's chemical engineering department students in his previous life, because its follow-up product is the first plastic in history, that is, celluloid.

With the help of purification techniques, high-concentration nitric acid and sulfuric acid can be easily obtained. In fact, Xia Lin can try to configure this kind of gunpowder a long time ago. However, the current chemical system in the industrial park has only a little foundation. This kind of thing is produced in small batches, and it doesn't change much from the status quo.

In addition, gunpowder, a kind of smokeless gunpowder, is dry and explosive when it is used alone, and it is not easy to store when it is wet, so he has never started to make it.

Now that the firing process of porcelain has been preliminarily mastered, it is possible to try to establish a simple chemical system to see if it can change the current situation.Although diatomaceous earth explosive is safe, stable and has excellent performance, it is not very suitable for propellant.

Many people have a misunderstanding about the three categories of gunpowder, explosives, and pyrotechnics, that is, energetic materials, or pyrotechnic agents. In fact, they also have different characteristics.

For example, gunpowder generally refers to a chemical substance that can burn rapidly and regularly by itself and generate a large amount of high-temperature gas under appropriate external conditions.

Its main purpose is to be used as a propellant for filling ammunition. Although this kind of propellant has requirements for power, it is not high. More attention is paid to the performance of the burning speed curve, which means that it can complete stable combustion within a certain period of time. , to generate enough high-temperature gas to push the projectile out of the chamber.

Explosives are chemical substances that can explode or detonate under certain external stimuli to do work externally. The time increases rapidly, thereby producing a large amount of high-temperature gas and flames to cause an explosion.

As for the pyrotechnic powder, it is a pyrotechnic chemical that mainly emits light and smoke. It is mainly used in military use as smoke bombs, and it is usually the main charge of fireworks.

Among the three types of pyrotechnic agents, the boundaries between the first two are not clear, but diatomite explosives classified as explosives are not suitable for use as bullet charges, because the deflagration of diatomite mother explosives produces High chamber pressure can easily damage the barrel of the rifle, causing accidents such as blasting the chamber.

Even if it is applied to artillery with stronger endurance, it needs to be used in conjunction with other propellants with a more stable and gentle burning rate to form so-called double-base propellants or multi-base propellants.Therefore, this kind of strong explosive is usually used in the fields of mine explosives, hand grenades, and explosive kits.

The configuration of gun cotton, which is most suitable as bullet propellant, is also quite simple.

Xia Lin repeated the preparation more than ten times, during which there were four accidental explosions. Fortunately, with the mage armor and the explosion-proof ditch outside the explosion-proof laboratory, he has been safe and sound. After going through these difficulties, he finally got a batch of Products of the required quality.

From the appearance, gun cotton is just a ball of ordinary slightly yellowed cotton. No one would think that these things would be a kind of dangerous goods at first glance, but Xia Lin knew that this kind of cotton mixed with nitro Concerned about the dangers of many related things, he carefully sandwiched the gunwool into the ethanol solution produced by the brewery, then covered the lid of the clay pot, and then coated a layer of water glass in the gap for Sealed and fireproof.

Having achieved the purpose of this trip, Xia Lin brought these two things to the gun factory to find Master Fine, and asked them to bring a batch of brass shells and bullet casings, and began to fill these ammunition.

The propellant of the shell can be mixed with diatomaceous earth explosive and gun cotton, which is also the simplest double-base propellant, and the bullet can be made of gun cotton that has been slightly treated with a stabilizer such as camphor.

After filling these two types of shells, it is natural to conduct a power test. The modified 2A rifle produced by the gun factory during this period has eight rounds of brass-shelled gunpowder propellant through the magazine. Bullets, for the sake of safety, Xia Lin asked people to use the original simple remote firing mechanism.

"Get ready! Let 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. There was a loud "Boom!", and the Type 2A, which was tightly tied to the gun rack, trembled violently After a while, the target in the distance fell down.

A tester stepped forward to straighten the gun frame, calibrated the target that the muzzle of the rifle was aiming at, and then fired again. After eight consecutive shots, the Type 2A rifle finally stopped.

"Wait first!"

Xia Lin stopped the testers from continuing the experiment, and went forward to take Master Fine and several young human apprentices with him to check the situation of the Type 2A rifle.

Fortunately, after this period of production, the steel factory has initially mastered the method of controlling the composition and quality of the steel output through the allocation of raw materials. It has improved a lot, otherwise Xia Lin is really worried that the Type 2A rifle will not be able to withstand the impact of this kind of copper shell bullet that uses gun cotton as the charge.

"Boss, this gunpowder is powerful enough!"

Master Fine touched the already hot barrel, looked at the target set at a distance of 200 meters or even 300 meters in the distance, but was still hit and exclaimed.

"This kind of propellant is more than powerful. Master Fine, haven't you discovered that it also has a unique advantage?"

Xia Lin reminded with a smile at Master Fine's praise.

"Another advantage?"

Master Fine took out a brass wine jug and took a sip of rum. After thinking about it for a while, he found nothing wrong. He suddenly showed a look of surprise and confusion. He had to scratch his head and said in a embarrassed way:

"I'm relatively stupid. Boss, you should stop being a fool. What kind of advantage are you talking about?"

"The advantage is that when this kind of gunpowder is fired, there is no smoke, and its combustion residue is very small! That is to say, in the past, our rifles used to use cleaning techniques after firing dozens of rounds each time. The rune plate cleans the gun chamber, now you don’t need to think about this problem, and the artillery is the same!"

Seeing this, Xia Lin stopped being a riddler, and told about a phenomenon that Master Fine and others just paid too much attention to the range and power of the rifle with this new type of ammunition and ignored it.
