Chapter 552 Aramid fiber and bulletproof ceramics

Lou Xiao'e left as quickly as she came. After reaching an initial agreement with Cao Zhiqiang, she left quickly without staying much.

It can be seen that Lou Xiao'e's impression of Cao Zhiqiang is not good. It is just a business relationship, which is completely different from her dealings with He Yuzhu.

But this is understandable, after all, Lou Xiao'e and He Yuzhu have a relationship, but she has no friendship with Cao Zhiqiang.

As for Cao Zhiqiang's courtyard background, it is not a plus for Lou Xiao'e, but a minus.

Because in Lou Xiao'e's view, except for the deaf old lady and He Yuzhu, there were no good people in the courtyard house in the past, and Cao Zhiqiang was no exception.

In fact, Cao Zhiqiang thinks this is good. The two parties are just doing business, and Cao Zhiqiang is more interested in it.

After smiling calmly, Cao Zhiqiang no longer thought about Lou Xiao'e's affairs, after all, this was one moment and the other was.

Anyway, since Shiweitian can be sold for 200,000 US dollars, Cao Zhiqiang has actually made a lot of money.

As Lou Xiao'e said, although food is the first thing, now customers are coming like clouds, business is very good, but in fact it is already at its highest peak.

If Shiweitian cannot take the opportunity to expand its business scale, this false fire will soon subside.

But if you expand your business scale, you need to continue investing and put a lot of energy into it.

Cao Zhiqiang's current thoughts are not on opening a restaurant. Even if it is to open a chain of restaurants, he only has this intention and does not want to start now.

In fact, opening a chain hotel is not that simple. It requires a unique management system and a large number of reliable trained employees.

In other words, the so-called franchise store model is not suitable at this time, because most people simply don’t have the money to invest, so they can only follow the McDonald’s model, and this model requires a formal management team, not just ideas and secret recipes.

That's fine.

Cao Zhiqiang thought about it. If he wanted to open a chain restaurant, he still had to go to Hong Kong or Japan to find some managers with experience in this area. Then he would first copy the external chain store management experience and training system, and then combine it with the actual situation in China.

, carry out the construction of chain stores.

However, chain restaurants are, after all, a physical industry with relatively large investments and slow capital turnover. The money coming in is not as fast as selling songs and books. Therefore, in Cao Zhiqiang’s plan, this industry can be developed, but it is a relatively low-end investment model.

For now, Cao Zhiqiang's main focus is still on singing and selling books. These models make money quickly, are cleaner, and are more resistant to investigation.

As for the sensitive items rewarded by the system, we can only give them to the country first.

Anyway, having a cheaper country is also good for you. Only when you have a country can you have a home.

If Cao Zhiqiang is just satisfied with being a little rich, then of course the issue of nationality does not matter and he can completely become a citizen of the world.

But Cao Zhiqiang doesn't want to settle down just being rich. He has bigger pursuits, and deep down he also hopes to make the country strong and become a more dignified Chinese citizen.

Under such circumstances, it is impossible for him not to rely on the system to help the country.

The system has now been upgraded. Every day you sign in, you will be given a certain amount of system coins. Then the original random reward for daily sign in has been changed to a lottery at least once every seven days.

In addition, after the system upgrade, there is also a system mall. Prizes that have been signed in before, as well as prizes obtained in subsequent draws, can appear in the system mall, and can then be purchased with system coins.

For example, the Geisha coffee beans that were obtained through lottery before, goat milk powder from the Alps, and even the Tu-160 bomber have all appeared in the system mall list.

All products have different prices, and the quantity is not limited. As long as you have enough system coins, you can purchase them in the mall.

In addition, exactly seven days had passed since the system was upgraded, and he finally remembered that he could draw a prize once.

After clicking the draw, there is no need to wait, the prize will appear soon.

[Full set of technical information on aramid 1313, plus four fully automatic production lines. (The production lines can be upgraded with system coins)]

[Full set of technical information on aramid 1414, plus four fully automatic production lines. (The production lines can be upgraded with system coins)]

[A complete set of technical information on alumina bulletproof ceramics, plus a full set of four automated production lines. (The production lines can be upgraded with system coins)]

Seeing the three messages that appeared in succession, Cao Zhiqiang raised his eyebrows.

"Oh, not bad."

It's really good. Although these three prizes may not look as high-end as the Tu-160 bomber, they are actually quite valuable.

Aramid 1313 refers to one of the aramid composite fibers. It is also the most widely used and produced one among the aramid fibers.

The biggest feature of this thing is its high temperature resistance. It can be used for a long time at a high temperature of 220℃ without aging. Its electrical and mechanical properties can be maintained for 10 years, and its dimensional stability is excellent. When it is around 250℃, its thermal

The shrinkage rate is only 1%.

In addition, this fiber product has excellent flame retardant and insulating properties, so it is an excellent fiber for making firefighting suits, training suits, racing suits, assault suits, space suits, and other high-quality functional clothing. It can also be used to make tire curtains.

cloth to increase the stability of the tire.

In addition, with this fiber, protective clothing can also be made in industrial fields such as petrochemical, electric power and gas, steel coking, electrical welding, etc., which can reduce a large number of safety hazards, which is of great significance.

This fiber has already appeared, but this technology has been monopolized by the United States for a long time. For a long time, only the United States and Japan have been able to survive. If there are no accidents, our country will not conquer this technology until the 21st century.

Difficulties, can be industrialized production.

Relatively speaking, the amount of aramid 1414 is small, but this fiber can be called a fiber revolution.

To put it simply, most people know relatively little about this stuff, but if we talk about Kevlar fiber, I’m afraid many people have heard of it.

That's right, the so-called bulletproof Kevlar fiber actually refers to aramid 1414 fiber.

Because aramid 1414 fiber has extremely high strength, greater than 28 grams per denier, which is six times that of high-quality steel, its modulus is three times that of high-quality steel, its toughness is twice that of high-quality steel, and its weight is only five times that of high-quality steel.

one.

In addition, this fiber also has excellent heat resistance, insulation and corrosion resistance properties, and has the reputation of "synthetic steel wire".

As for the scope of application, it is too wide. In addition to making body armor and bulletproof helmets, it can also make tire cords, optical cable protective layers, industrial hoses, brake pads, anti-cut gloves, etc.

In the same way, aramid 1414 fiber has been monopolized by the United States for a long time. my country also only completed its public relations in the 21st century and developed its own technology and production capabilities.

Compared with these two aramid fibers, alumina bulletproof ceramics are much simpler. Their main function is bulletproof.

Such bulletproof ceramics are generally used in common bulletproof inserts and composite bulletproof armor on armored vehicles.

In fact, in the field of bulletproof, bulletproof ceramics made of alumina are not the best, but they are the easiest to produce, have the most materials, are the cheapest, and are the most cost-effective bulletproof ceramics.

At present, alumina bulletproof ceramics are still only mastered by the United States. Generally speaking, it was only in the 21st century that my country overcame the difficulties and was able to produce its own alumina bulletproof ceramics.

It is precisely because China has conquered the alumina bulletproof ceramics and domestically produced aramid 1414 that domestically produced bulletproof vests have become popular, and soon became the largest producer of bulletproof vests in the world. Even the United States, in the 21st century

At that time, a large amount of Chinese bulletproof equipment was also imported.

Now, Cao Zhiqiang can directly obtain the full set of production technology for these things, as well as the upgradeable automatic production line. This is equivalent to instantly acquiring this technology and gaining the ability to quickly produce this fiber.

In the 1980s, these three items were definitely great weapons for exporting and earning foreign exchange. Moreover, they did not need to be hidden away like the Tu-160 bomber, and they could export finished products openly.

Not only that, in addition to the four production lines directly given in the lottery, if Cao Zhiqiang wants to expand production capacity in the future, he can also use system coins to purchase production lines directly from the system mall.

It’s just that the price is a bit expensive. An automated production line of aramid 1414 costs 300,000 system coins. When upgrading the production line, the price will vary according to different technical levels.

Although Cao Zhiqiang currently signs in every day, he has accumulated 60,000 system coins so far, and he can currently reward at least 10,000 system coins for signing in every day. If he signs in continuously in the future, it is estimated that the daily rewards will be even more.

This seems like a lot, but unfortunately Cao Zhiqiang wants to buy too many things, and this little money is simply not enough.

Compared with this system currency, the aramid production line is not the most urgent.

Of course, if it were just from Cao Zhiqiang’s personal perspective, it would not be bad to set up an aramid fiber production company.

At least in this era, whether it is aramid fiber or bulletproof ceramics, they are definitely high-tech projects that make a lot of money.

As long as the production line is on line, the workers are trained a little, the materials are prepared, and then the money is collected.

Not to mention foreign countries, Cao Zhiqiang can make a lot of money from domestic demand alone.

"The prizes are good, but it's too late to get them now, and the equipment is also a bit sensitive. At least the source is an issue.

It’s better to save it now and wait until you have the opportunity to spit out these devices and push them on the mysterious organization codenamed Mist.”

Thinking of this, Cao Zhiqiang felt a little sad, feeling that he had one more choice, which equaled one more trouble.

Everyone is worried because there are too few good things, but he is worried because there are too many good things.

This is really not hypocritical, it is true.

The biggest problem is how Cao Zhiqiang can launder the prizes produced by these systems and make them at least acceptable.

Anyway, Cao Zhiqiang can't tell people directly that these things he has are because he has a portable system, and the system rewards him, right?

He thought about doing this, but considering the risks, he decisively rejected the idea.

Cao Zhiqiang is patriotic, but he cares more about his own life and freedom than patriotism.

What's more, the current high-level officials in the country may not be trustworthy. At least many people have ideological problems.

If he dares to reveal the secret, there is no guarantee that it will be leaked to the United States by some people in the country. And if the United States knows about it, it will definitely send people to carry out assassinations and kidnappings. This is entirely possible.

Just when Cao Zhiqiang was still thinking about how to bring these gadgets to China in a reasonable and reasonable way, and then set up his own company to produce related products, someone suddenly called him.

"Hello, President Cao, I finally found you."

Cao Zhiqiang was stunned, and when he looked up, he saw that it was Anping.

Anping was one of the two "secretaries" assigned to him by Uncle Lin, and he was also the male secretary.

Compared with Xu Chun, a female secretary who is more technical, Anping is more inclined to play a bodyguard role, and in most cases, being a male Anping is actually more convenient.

Of course, since they were sent by a secret front affiliated with the military, the identities and origins of Anping and Xu Chun were also clearly arranged.

At least you will never be able to find out the true identities of Xu Chun and Anping through any hacking or other actions.

In addition, the mainland is the mainland after all, and the systems are different. If you really want to keep things confidential, it is difficult for outsiders to get in touch with the core confidentiality department.

In other words, the level of domestic agents may be average abroad, but when it comes to keeping secrets at home, they are definitely world-class. Regardless of the Soviet Union or the United States, they are not enough.

In fact, the legendary two and three parts of so-and-so are just legends. If it is implemented in detail, outsiders will not know the secret behind it.

Just like Uncle Lin, his level is definitely very high.

But when Uncle Lin contacted Cao Zhiqiang, he never mentioned his specific position or what department he was from.

Don't say that Cao Zhiqiang didn't ask, even if he asked, he probably wouldn't get an answer.

Anyway, Uncle Lin can't be from the newly established security department.

Therefore, as long as Cao Zhiqiang does not tell anyone, the security index of his line is still very high. After all, his confidentiality level must be very high.

In short, the identities of Anping and Xu Chun seem to be normal at present. They were both transferred here normally. They were both from rural areas, but they are ordinary college student cadres with outstanding talents. Their official positions are in the office of the president of Hongguang Publishing House.

Ordinary intern officer.

Hongguang Publishing House originally did not have a president's office. Even after Xiang Dongfang was transferred and became Cao Zhiqiang's first secretary to the president, there was still no so-called president's office.

However, in order to properly arrange Anping and Xu Chun, Cao Zhiqiang established a new president's office and arranged Xiang Dongfang, Xu Chun and Anping into it.

The staff in the president's office of Hongguang Publishing House can all be called the president's secretary. Xiang Dongfang, Xu Chun and Anping are all at the same level. In theory, the three of them take turns serving Cao Zhiqiang.

However, in actual operation, Xiang Dongfang mostly handles the internal affairs of the publishing house. Once it comes to business trips abroad, Cao Zhiqiang will lead Xu Chun and Anping who are proficient in Japanese.

Xiang Dongfang also understands Japanese, but she is not proficient in it, at least not to the level of a translator. After all, she is proficient in English.

Xu Chun and Anping are different. Both of them can work as Japanese translators, so it is reasonable and reasonable to take them to Japan, and no one will doubt it.

In fact, the reason why these two people were originally brought in was because they were proficient in Japanese.

In short, let alone foreign countries, even if people in China are really willing to work hard to investigate the origins of Anping and Xu Chun, they will never find any problems. They will only find the content they want you to see.

"Ah, it's Xiao An, what a coincidence." Cao Zhiqiang chuckled, "Do you have a problem with me?"

Anping smiled slightly: "There is something wrong, this..."

Having said this, Anping looked around naturally and quickly to make sure that no one was paying attention or eavesdropping, and then whispered: "The signal tower is inviting me."
