Technological Hegemony

In the past, when people were poor, people were looking forward to eating something delicious and buying new clothes.

Nowadays, life is getting better and better. Food for Chinese New Year is no longer different from usual. New clothes are nowhere to be talked. As long as there is demand, they can be bought at any time.

I gradually heard a voice saying that Chinese New Year is a boring thing. After returning home, I still have to be forced to marry my elders.

In this regard, Luo Jia did not agree.

Huaxia's Spring Festival is getting lighter and weaker. The reason is that the tradition is lost.

Luo Jia envied the Chaoshan area in the south. The traditional culture is well maintained. During the Spring Festival, there are always many traditional activities. These activities are not only lively, but also have a sense of ceremony. The sense of ceremony is just an indispensable part of life. .

罗 Every time Luo Jia saw and bid farewell to the hero's body, the coffin was covered with the national flag, and his comrades in military uniforms and shot at Tian, ​​he always had a tearful urge.

This is the sense of ritual.

Traditions have not been inherited, and there is not enough sense of laughter and ceremonies. In addition, many cities also prohibit the display of fireworks, which eventually leads to a waning year.

Paradoxically, people do not need to be spiritually rich when they are not full, but it is precisely that Chinese people now have enough food. The rise of Hanfu and the ancient style is that the people are searching for themselves and returning to the spirit. The performance of the source.

People are now keen on Western festivals such as Christmas and Valentine's Day, but also because they can't find the spiritual sustenance they need from traditional festivals, so they have to resort to the West.

Luo Jia, who is accustomed to thinking, can't relax his head even during the Spring Festival holiday. So he called Zhang Dongning on the first day of the New Year. In addition to the Chinese New Year greetings, he also proposed that the chemical department he manages would work out Fireworks polluting the environment came out.

This firework must be stunning, brilliant, and have the dream effect of bursting the entire night sky.

At the same time, it must also be very environmentally friendly, very cheap, and must not pose a fire hazard, easy to produce, and convenient for large-scale use.

Zhang Dongning had a headache when he heard it. He sighed and said, "General Luo, we have no problem with organic chemistry. The Department of Chemistry is now a large department with nearly 1,000 researchers. The key is that your request is really abnormal."

"It needs to be brilliant, it must be cheap, it must be environmentally friendly and there is no hidden danger of fire. If you want to achieve this effect, shouldn't we be able to do it in our chemistry department? You should find the electrical department or the optical department to do it."

Luo Luojia shook her head, "Optical fireworks have long been proven to be scammers, and fireworks and fireworks can't burst explosive fireworks, what kind of fireworks?"

"This matter can only be done by your chemistry department. I have already thought about it. I will use hexamethylenetetramine! You will wait for a while and I will send you an email."

Zhang Dongning stunned suddenly. Hexamethylenetetramine, also known as urothine, is an organic chemical preparation that is usually used to eliminate body odor.

The vast majority of Huaxia people have no body odor, so they are not very familiar with this thing.

But in other parts of the world, deodorants containing urothine are everywhere. There is no way. Who causes the foreigner evolution chain to have a problem, and the body has a serious odor.

In addition to removing body odor, hexamethylenetetramine can also be used as a smokeless fuel, which has a very sturdy burning effect, but does not produce soot.

Zhang Dongning was thinking, and suddenly the phone vibrated slightly, and Luo Jia's email had been delivered.

Zhang Dongning opened it and saw that it was a very complicated chemical formula and a synthetic step.

(CH2) 6N4 + 10HNO3 → (CH2-N-NO2) 3 + 3CH2 (ONO2) 2 + NH4NO3 + 3H2O ...

This is very scary. At first glance, it looks like synthetic trimethylenetrinitramine, a very unstable explosive, commonly known as cyclone explosive, English abbreviation RDX.

However, if you look closely, it is not.

Luo Jia very cleverly designed a model that added hexamethylenetetramine in the sub-zero state, which successfully prevented the exothermic reaction. Without the exothermic reaction, nitric acid cannot be decomposed and nitrogen oxides such as N2O.NO2 cannot be generated .

In short, through a series of complex chemical reactions and operations, a new type of combustion substance that is completely smokeless but has a very explosive effect will eventually be obtained.

稳定性 Its stability is also foreseeable. The only disadvantage is that it is more complicated to operate. Most of the operations are carried out at minus ten degrees to control the exothermic reaction.

Like most combustion chemical synthesis, the process of producing this thing is risky, but the risk is controllable. Once the synthesis is completed, the final product will be very safe.

东 Zhang Dongning finally understood Luo Jia's design. He felt that his back was upright. He only knew that Luo Jia knew chemistry, but he didn't know he knew so much, so deep!

好 Is smokeless fireworks good in design?

Of course, it is not easy to design. If it is easy to do it, the chemistry world would have already started it. After all, China has a tradition of setting off fireworks. The ancient tradition that has been passed down for thousands of years is gone.

Picked up the phone, Zhang Dongning called Luo Jia again, "General Luo, this thing can be done! If nothing happens, the effect will be very cracked, but there are three disadvantages."

"You said." Luo Jia said over the phone.

"First, it's synthetic risk."

"This is easy to solve. Establish an unmanned factory in a remote area. Use the intelligent robot arm of Xingchen instead of human. The robot arm has high accuracy and is very stable."

Zhang Dongning froze for a moment, and he almost forgot that Xingchen Technology also has an almost invisible subsidiary, Xingchen Smart.

Xingchen Intelligent made nothing, specialized in manufacturing robotic arms, and the products were only used by the parent company.

Xingchen Technology's production line is so efficient and the output is so large. The reason is that they have the best robotic arm in the world.

As for why Xingchen's intelligent robotic arm is not for take-out, Luo Jia is worried that once this thing is sold in large quantities, workers will lose their jobs, and Huaxia has not developed to the point that it can fully use machinery to replace people.

Zhang Dongning paused. "Second, it is still a burning substance, and there is still a risk of fire."

Luo Jia nodded. "It's true, so I plan to make only large fireworks bombs, which will be uniformly released by the public sector ~ www.wuxiahere.com ~ Anyway, fireworks are also for viewing, as long as everyone can see it, bring the atmosphere up Just fine. "

东 Zhang Dongning also said, "Third, it is the problem of colorants. Fireworks cannot have only one color. New chemical compounds can only solve the problem of combustion. They cannot solve the problem of color of fireworks. In addition, we have no experience in the design of fireworks."

Luo Luojia said, "There is no problem with this. The dye and deflagration effect are the patents of the fireworks factory. We directly purchase the largest domestic factory and buy all their talents and patents."

After listening to Luo Jia's words, Zhang Dongning said with a smile, "If this is the case, then there is no problem, but I don't quite understand, why should I devote energy to this small project that obviously will not be profitable?"

Luo Luojia said with a smile, "How can we say that the Chinese tradition is a small project?"

"When I was young, every 15th Lantern Festival on the first day of the first month, fireworks were set off in the city and in various courtyards. I took a little money from my mother, bought some small fireworks, and gathered with my companions. All day, I still miss that atmosphere. "

"With the development of society, the tradition has become less and less. Can you leave a little bit?"

都 "Everyone said that fireworks are cold, but I hope it will never be cold."

Zhang Dongning felt a power from Luo Jia's words. At the same time, he thought of Luo Jia's speech. The real renaissance is not only the economic and technological renaissance, but also the strong return of culture and tradition.

Hua Xia has burned fireworks for thousands of years. It should not be cooled down in our generation, but in our generation, it should bloom with a brighter posture!

Thinking of this, Zhang Dongning nodded gently and said, "Leave it to me, the Ministry of Chemistry promises to complete the task!"
