In the past, when they were poor, people looked forward to eating something delicious and buying new clothes during the Chinese New Year.

Now that life is gradually becoming well-off, the food eaten during the New Year is no longer any different from usual, and there is no way to talk about new clothes, as long as there is a demand, you can buy them at any time.

So there was gradually a voice, saying that the New Year is a boring thing, and after returning home, you will be forced to marry by your elders, so it is better not to live in the New Year.

Luo Jia disagreed.

The Chinese Spring Festival is getting weaker and weaker, and the reason for this is because of the loss of tradition.

Luo Jia is very envious of the Chaoshan region in the south, the traditional culture is maintained really well, every Spring Festival, there are always many traditional activities, these activities are not only lively, but also very ritualistic, and the sense of ritual is an indispensable part of life.

Whenever Luo Jia saw the scene of bidding farewell to the remains of heroes, the coffins covered with national flags, and his comrades-in-arms wearing straight military uniforms and firing guns into the sky, he always had the urge to burst into tears.

That's the sense of ritual.

The lack of tradition, laughter and rituals, and the ban on fireworks in many cities have led to a growing New Year's flavor.

The contradiction is that when people can't eat enough, they naturally don't need to be spiritually rich, but it is precisely now that Chinese people can eat enough, and the rise of Hanfu and ancient customs is the manifestation of the folk in self-search and self-return to the spiritual origin.

People are now keen to celebrate Western holidays 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 turn to the West for help.

Luo Jia, who is accustomed to thinking, even during the Spring Festival holiday, his head is not idle, so he called Zhang Dongning on the first day of the Lunar New Year, in addition to the Spring Festival greetings, and proposed to let the chemistry department he manage to make a kind of fireworks that will not pollute the environment.

This kind of fireworks must be stunning, brilliant, and have the fantastic effect of exploding the entire night sky.

At the same time, it has to be very environmentally friendly, very cheap, never pose a fire hazard, easy to produce, and convenient for mass use.

Zhang Dongning had a headache when he heard this, he sighed and said, "Mr. Luo, we have no problem with organic chemistry, and the Department of Chemistry is now a large department with nearly 1,000 researchers. ”

"To be brilliant, but also cheap, but also to be environmentally friendly and no fire hazards, if you want to achieve such an effect, it should not be something that our chemical department can do, right? You should go to the electrical department or the optical department to do it. ”

Luo Jia shook his head, "Optical fireworks have long been proven to be liars, and fireworks fireworks, fireworks that can't explode and ignite, what kind of fireworks are they?" ”

"This can only be done by your chemistry department, I have already thought about it, just use hexamethylenetetramine! Wait a minute, I'll send you an email. ”

Zhang Dongning was stunned, hexamethylenetetramine, also known as Wuluopin, is an organic chemical agent that is usually used to eliminate fox odor.

The vast majority of Chinese people don't have fox odor, so they are not very familiar with this thing.

But in other parts of the world, deodorants containing Ulo are everywhere, and there is no way, who made the foreigner's evolution chain go wrong, and the smell on his body is more serious.

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

Zhang Dongning was thinking about it, when suddenly his mobile phone vibrated slightly, and Luo Jia's email had been delivered.

Zhang Dongning opened it and saw that it was a very complex chemical formula, as well as a synthesis step.

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

This is very scary, at first glance it looks like the synthesis of trimethyltrinitroamine, a very unstable explosive, commonly known as cyclone explosives, abbreviated as RDX in English.

However, on closer inspection, it is not.

Luo Jia very ingeniously designed a model in the sub-zero state, adding hexamethylenetetramine, successfully preventing the exothermic reaction, without which nitric acid cannot be decomposed and cannot produce nitrogen oxides such as 2.

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.

Its stability is also predictable, the only drawback is that the operation is more complicated, most of the operation is carried out in an environment of minus 10 degrees Celsius, in order to control the exothermic reaction.

As with most combustion chemical synthesis, the process of producing this thing is risky, but the risks are manageable, and once the synthesis is complete, the final product is very safe.

Zhang Dongning finally understood Luo Jia's design, he felt the hairs on his back stand on end, he only knew that Luo Jia understood chemistry in the past, but he didn't know that he knew so much, so deeply!

Are smokeless fireworks good designed?

Of course, it's not easy to design, if it's easy to do, the chemical community would have done it a long time ago, after all, Huaxia has a tradition of fireworks, and the ancient tradition of thousands of years is gone.

Picking up the phone, Zhang Dongning called Luo Jia again, "Mr. Luo, this thing can be done!" If nothing else, the effect will be very explosive, but there are three drawbacks. ”

"You say." Luo Jia said on the other end of the phone.

"First of all, there is the risk of synthesis."

"This is easy to solve, establish an unmanned factory in remote areas, and replace manual labor with Xingchen Intelligent's robotic arm, which has high precision and is very stable."

Zhang Dongning was stunned for a moment, he almost forgot that Xingchen Technology also has an almost invisible subsidiary, Xingchen Intelligence.

Xingchen Intelligent does not make anything, specializes in making robotic arms, and the products are only used by the parent company.

The reason why Xingchen Technology's production line is so efficient and has such a large output is precisely because they have the best robotic arm in the world.

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

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

Luo Jia nodded, "That's true, so I plan to only make large-scale fireworks bombs and set them off by the public sector, anyway, the fireworks are also for viewing, as long as everyone can see them, bring the atmosphere up." ”

Zhang Dongning also said, "Third, is the problem of dyes, fireworks can not only have one color, new chemical compounds can only solve the problem of combustion, can not solve the problem of fireworks color, and we have no experience in the design of fireworks." ”

Luo Jia said, "There is no problem with this, the dye and deflagration effect are the patents of the fireworks factory, and we directly buy the largest factory in China and buy their talents and patents." ”

After listening to Luo Jia's words, Zhang Dongning said with a smile, "If that's the case, then there's no problem, but I don't quite understand, why do you want to spend energy on this small project that obviously won't be profitable?" ”

Luo Jia smiled and said, "How can you say that the Chinese tradition is a small project?" ”

"When I was a child, every Lantern Festival on the 15th day of the first lunar month, fireworks would be set off in the city and in various courtyards, and I took a little money from my mother to buy some small fireworks, and get together with my companions, and be happy all day, that atmosphere still makes me nostalgic."

"With the development of society, there are fewer and fewer traditions, and it is a little bit to be able to leave a little bit."

"They say that fireworks are easy to get cold, but I hope it never gets cold."

Zhang Dongning felt a kind of power from Luo Jia's words, and he also thought of Luo Jia's speech, the real revival is not only the revival of economy and science and technology, but also the strong return of culture and tradition, and the world will be determined!

The fireworks that have been burning in China for thousands of years should not be cold in our generation, but should bloom in a more brilliant attitude in our generation!

Thinking of this, Zhang Dongning nodded lightly and said, "Leave it to me, the Department of Chemistry guarantees to complete the task!" ”
