Chapter 215 Bullets and propellant

Chapter 215 Bullets and Propellant

Zhao Xin, who is in another time and space, still doesn't know that he was almost deceived into becoming the spokesperson of the "bastard" in the human world. If he knew this, he might tie Jiang Xiucai to a stone and throw the bastard together.

Enter Suifenhe.

After struggling for a long time, I finally bought the cargo ship. This 60,000-ton container ship was built in 2013, with a length of 250 meters and a draft of 14 meters. After Zhao Xin completed the formalities, in view of the work efficiency of Africans, he decided to use

Bonuses are provided to encourage these people to complete the renovation project as quickly as possible.

The construction period given by the shipyard was one year, and Zhao Xin directly limited it to three months. When the shipyard boss heard Zhao Xin’s proposal for the periodic bonus amount, he signed the agreement very happily. The renovation project includes hull maintenance, removal of

Box grid guide posts on the deck, installation of pod side thrusters, main deck reinforcement and other projects.

On the day after signing the renovation agreement, Zhao Xin found a Swiss supervision company to serve as project supervisor. Why did he choose Swiss people? To sum it up in one sentence, this is a group of French people who do not want to be French and are more German than Germans.

German; strict to the point of being annoying.

Sure enough, money was flowing all the way. When everything was ready and the first project payment was paid to the shipyard's account, the freighter sailed into the dry dock that day. Seeing that the project had begun and the supervisor came in, Zhao Xin embarked on his return journey.

the journey.

Two days later, Zhao Xin met with Andrew via Europe. He purchased another 5,000 SKS this time; and the bullet production line that Andrew helped purchase last year has been disassembled and shipped, and will be shipped by train in another 20 days.

Arrive at the ice-free port.

As an intermediate-power bullet, each 7.62mm bullet is composed of a cartridge case and a warhead, and the warhead is divided into a warhead case and a cartridge core. These three parts need to be produced separately and assembled together in the final step.

The processing of the cartridge case is relatively simple. It mainly uses the reverse extrusion method to basically shape the cartridge case barrel. Then use a notching machine to cut off the waste material formed above the cartridge case barrel, and then clean it with chemical reagents and surface treat the bottom of the cartridge case.

.

The processing process of the bullet is divided into four processes: drawing processing, punching, making the bullet core, and bullet assembly.

After completing the manufacturing of the warhead and cartridge case, it is time to enter the process of assembling the finished bullet. Assembling a finished bullet is mainly divided into two parts, with the cartridge case as the main part, namely the processing of the primer and the assembly of the bullet. After the primer is installed

Finally, the machine tool simultaneously applies sealing paint between the primer and the cartridge case to prevent the primer from getting wet and causing the bullet to fail. Finally, the bomb assembly machine feeds the weighed propellant into the cartridge case, and finally squeezes the warhead in, and waits for weighing

Only after inspection and appearance inspection can a qualified bullet be born.

Although such a large production line is very important, Zhao Xin cannot use it even after it is installed and can only be temporarily locked in the warehouse. First, power generation equipment and various oils have become the biggest constraints to the current development of Beihai Town; second,

There are not enough skilled workers.

To celebrate the completion of these two businesses, Andrew decided to treat Zhao Xin to a big dinner.

While waiting for the food to be served, Andrew began to show off his newly bought big yacht to Zhao Xin. When Zhao Xin looked at the photo, he discovered that this guy also bought an Azimut yacht. However, Andrew had a nouveau riche mentality and actually bought a ti Told u

So super yacht.

“It looks great!”

Andrew was proud: "This boat can accommodate 10 passengers and can host a large party of 60 people at the same time."

"Oh, so where is your boat docked now?"

“Italy of course!”

Zhao Xin fantasized about the hot scene of a carnival party, with a large group of beauties and an ugly guy called Andrew. Hey! He shuddered. But then he thought about it again, this guy was just an ordinary guy last year, and now he looks like a billionaire with arrogance.

You got it all from yourself!

Andrew put away his phone and asked casually: "Zhao, you are so rich, why don't you buy a yacht?"

"Me? These boats are too small to look at." The waiter served the appetizers, and Zhao Xin prepared to concentrate on the seafood salad in front of him.

"Azimut also has large yachts. When I was choosing a yacht, someone told me about the LANA, which is 300 feet long. Zhao, you should buy one. We can be a companion and go fishing together when we have time."

Zhao Xin asked casually: "LANA number? How much does it cost?"

"Three hundred million dollars."

"Your uncle~!" Zhao Xin cursed in his heart. But suddenly he felt something in his heart and said tentatively: "It's boring. If I have the conditions, I will buy a warship and use it as a yacht."

"You have a good idea! I heard that a rich man in the Middle East did this. Let's drink a drink to this crazy idea!" Andrew raised his neck, and the large glass of brandy was gone in the blink of an eye.

Zhao Xin put down his wine glass and said with a smile: "Crazy? No, my friend. As long as you are bold and rich, it shouldn't be difficult to buy a warship."

"There are many old warships that have been retired, but it is too expensive to renovate them. It is more expensive than buying a new one."

"Oh. What about buying a small frigate?"

"You mean?" There is no fool who can do the arms business. Andrew quickly reacted. He stared at Zhao Xin for a while, and then a strange smile appeared on his face.

After that, the two of them had a tacit understanding and never mentioned the warship again, but Zhao Xin knew that Andrew had understood what he meant.

In fact, the small frigates of a northern country are not expensive. The cost of an 800-ton frigate is only 30 million US dollars, with a length of 65 meters and a top speed of 30 nautical miles (56 kilometers). There is a deck at the stern for operating large helicopters and drones.

A crew member can stay at sea for 15 days at a time.

The weapon system that was originally supposed to be equipped included a 76mm rapid-fire gun, eight launch tubes that could accommodate a 1.2-ton anti-ship missile with a range of 300 kilometers or an anti-ship missile with a range of 600 kilometers, two 14.5mm machine guns, and two

A multi-barreled 30mm automatic cannon. In addition, there are 32 anti-aircraft missiles. But in the 18th century, who should be hit with anti-ship missiles?

Want to build a sailing warship? This is too wasteful!

There are also helicopter decks and anti-aircraft missiles, which are completely useless! Instead of this, it is better to install two 76mm cannons and an additional 30mm automatic cannon.

Let's test it out first to see if we can open the way to purchase naval equipment. If we really give Zhao Xin a destroyer, with the current technical level of Beihai Town, it can only be used as a coastal fort.

Two days later, when Zhao Xin returned to Beihai Town, he found that the entire western part of the town had turned into a large construction site. A mile away from the seaside at the western end of the town, several excavators and thousands of people had been working hard for many days.

The appearance of a huge dry dock has begun to take shape. The east-west road in the center of the town continues to extend westward. Refugees from Henan and Shandong are building wood carvings on both sides of the road.

Chen Qingsong's arrangement for these newly arrived refugees is to arrange for two families to stay in each wooden house to deal with this winter first. In the spring of next year, many people will go north to Fuldan City to open up the vast area on the south bank of Xingkai Lake.

Even so, Beihai Town, which accepts refugees, still has to build a large number of houses. Zhao Xin once told Lu Shoushan that the number of people transported to Beihai Town this year will reach at least 15,000.

The civil affairs department that Chen Qingsong was responsible for worked continuously for seven or eight days before completing the population registration of the first batch of 5,000 Qing refugees and appointing the following group leaders and district chiefs. As for the district chief, Chen Qingsong decided not to use it for the time being.

Let’s wait until the first batch of refugees get used to the various living systems here.

On the afternoon of Zhao Xin's return, more than a hundred newly elected residents' group leaders and a dozen district leaders attended the first meeting convened by the local Mr. Chen with trepidation. Chen Qingsong communicated with the school.

A large classroom in the school was temporarily requisitioned.

More than a hundred refugees, led by several officials from the Ministry of Civil Affairs and supervised by seven or eight armed security police, walked into the school in surprise. At this time, classes were still in other classrooms. When they heard loud reading,

When the sound was heard, the faces of these refugees from Henan showed envious expressions.

In the hearts of ancient farmers, those who go to school will become masters in the future. So these people did not even dare to make a fuss and walked into the classroom quietly. As a result, the few people walking in front immediately became stupid as soon as they entered the classroom.

Well, the landlord’s house is not so clean and bright.

"Is this a school?" Several homeless people from Henan Province wearing tattered cotton-padded clothes didn't even dare to step forward. They felt that if they walked inside, they would pollute the place.

"Come in, it's warm inside. Find a place to sit down." Chen Qingsong stood on the podium and said with a smile to the people who were in a daze.

Looking at Chen Qingsong's smile, Zhu Dagui, who was standing at the front, quickly bent down and saluted. When he was on the boat, he heard from the sailors that kneeling was not popular here in Beihai. If the masters saw you kneeling to them, they would still do it.

Angry. Zhu Dagui felt strange, how could there be any reason in the world not to kneel down when seeing the master?

The smiling old man Zhu Dagui in front of him had seen him when he got off the boat. Those who reported to him really didn't kneel down. Ever since he was appointed as the team leader in a daze, Zhu Dagui thought that the old man was choosing a yamen servant, so of course

He wanted to kneel down to express gratitude. Unexpectedly, as soon as he knelt down, he was scolded. He was told that if he continued to kneel down, he would be stripped of his position as group leader.

After three days, Zhu Dagui found out who the team leader was. It turned out that he was just an errand boy with no salary. He was not happy about this. According to Zhu Dagui's idea, everyone kept behind closed doors.

Live your life, why do you need me to repeat what the master said, I don’t even have ears?! It’s so cold now, if you have this free time, it’s true that you should move into the house as soon as possible.

As more and more people walked into the classroom, it quickly became crowded. Some people either sat on a chair next to someone they knew, and some simply squatted on the ground.

Chen Qingsong first made an opening statement: "Let me introduce myself. My surname is Chen, and my name is Chen Qingsong. I am responsible for managing civil affairs here in Beihai. What is civil affairs? It means teaching everyone how to live here, how to farm, and how to work.

I guess someone has said it, so you don’t even have to say it. Who among the bankers can’t do this?”

The laughter they imagined did not appear, and a group of farmers looked at Chen Qingsong blankly. They had never seen such an official!

Just listen to Chen Qingsong continue: "Everyone comes here, and from now on they can farm and work with peace of mind. Let me tell you a secret, although the winter here is long, the black soil is full of fat! This year we are seven

The monthly harvest of grain is six hundred catties per mu."

What?! All the farmers in the room were shocked! Six hundred catties?!

Let’s not talk about the severe drought and floods in the past two years. Even if the weather is good in previous years and a bead of sweat breaks into eight pieces on the ground, the harvest of sorghum per mu will only be 200 to 300 kilograms.

Zhu Dagui's mind was buzzing, and the only words that were running through his mind were the words "six hundred catties." According to his previous experience as a tenant, half of the harvest was paid for rent, and his family could still be left with three hundred catties?! This is simply

What a magical day!

Someone among the refugees in the classroom said, "Sir, are you telling the truth? I've never seen one acre of land produce six hundred kilograms of sorghum!"

Chen Qingsong smiled and said: "I'm not talking about sorghum, but wheat, and white flour!"

As soon as these words came out, the jaws of more than a hundred farmers in the classroom dropped to the ground. Oh my god! I have been farming all my life and have never eaten white flour. If I can eat sorghum porridge and boiled vegetables and leaves, I will have a safe life.

.After they disembarked these days, they ate corn cob porridge and big wotou with dried fish and cabbage. This made all the refugees feel grateful and burst into tears.

"We have a rule here." Chen Qingsong deliberately stopped and scanned the people in the room.

"Everyone, I mean everyone, you don't have to pay rent for the first five years, and all the food you grow belongs to you! From the sixth year onwards, you will only receive 10% of the annual rent!"

Boom! Four big and small kings, two and four guns, and a big straight. All the more than a hundred Henan farmers in the classroom were stunned!

In the workshop on the east bank of the river, Zhao Xin found Fang Hua who was busy and told him about the bullet production line. Then Zhao Xin asked him whether bullet propellant could be produced.

In later generations, with the emergence of smokeless gunpowder, double-base gunpowder, detonators, TNT, etc. in the 19th century, black powder originally used as propellant has been basically eliminated.

Early smokeless gunpowder generally used nitrocellulose invented by the Swiss Schönbai. The gunpowder produced in this way was very unstable and exploded many times. In the 1880s, the Frenchman P. Viery

Dissolve nitrocellulose in ether and alcohol, add an appropriate amount of stabilizer to it, and form a gel. After pressing into sheets, cutting into strips, and drying and hardening, the world's first smokeless gunpowder was made.

Upon hearing this, Fang Hua said casually: "As long as you have absorbent cotton and nitric acid, this is easy. However, this is a flammable product. Once it is manufactured in large quantities, you must pay attention to its preservation."

Zhao Xindao: "But why did I hear that nitrocellulose film is easy to explode?"

Fang Hua said: "It needs to be stabilized. And it must not come into contact with acidic substances."

Zhao Xin scratched his head and asked: "Sleeping pills?" For a chemical idiot like him, his first reaction was "sleeping pills."

Fang Hua smiled bitterly and shook his head. He thought for a while and explained in the simplest terms: "The stabilization process is actually adding a wetting agent. Nitrocellulose will be accompanied by unstable impurities during the manufacturing process, and these unstable impurities are easily decomposed.

.At the same time, the decomposition process will continue to accelerate the decomposition rate of nitrocellulose. Only when nitrocellulose is stabilized to completely remove unstable impurities and slow down the catalytic effect of nitrocellulose can it be stored for a long time. In addition, if

To ensure the safety of transportation of nitrocellulose, we can also add plasticizer to plasticize and compress it to obtain nitrocellulose paint flakes."

OK, Zhao Xin understood it immediately.
