When I was poor in the past, people hoped to eat something delicious during the Chinese New Year and buy new clothes.

Now that life is getting better and better, there is no difference between the food you eat during the Chinese New Year and the usual, and there is no way to talk about new clothes. As long as there is a need, you can buy them at any time.

So gradually there was a voice saying that the New Year is boring, and it would be better to be the New Year after I got home and I would be forced to marry by my elders.

Luo Jia did not agree with this.

The Chinese Spring Festival is getting lighter and weaker, and the reason is that it is the loss of tradition.

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

Whenever Luo Jia saw the scene of saying goodbye to the hero's body, the coffin was covered with national flags, and his comrades were wearing straight military uniforms and firing guns into the sky, he always had the urge to burst into tears.

This is the sense of ritual.

The tradition has not been inherited, and the sense of rituals is insufficient. In addition, many cities have banned the setting of fireworks, which ultimately leads to the current New Year atmosphere becoming increasingly weaker.

Contrary to this, when people are unable to eat enough, they naturally do not need to be full of energy, but today's Chinese people can already eat enough. The rise of Hanfu and ancient style is a manifestation of the people's self-seeking and self-returning to the spiritual origin.

People are now keen on celebrating Western festivals such as Christmas and Valentine's Day, and because they cannot find the spiritual sustenance they need from traditional festivals, they have to turn to the West.

Luo Jia, who is used to thinking, couldn't rest even during the Spring Festival holiday, so he called Zhang Dongning on the first day of the Lunar New Year. In addition to greetings on the Spring Festival, he also proposed that the Department of Chemistry, which he managed, create a firework that will not pollute the environment.

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

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

Zhang Dongning had a headache when he heard this. He sighed and said, "Mr. Luo, we have no problem with organic chemistry. The Ministry of Chemistry is now a large department with nearly a thousand researchers. The key is that your requirements are really a bit biàn tài."

"It is to be brilliant, cheap, and environmentally friendly and without fire hazards. To achieve such an effect, it should not be possible for our chemistry department to do it, right? You should contact the electrical department or the optical department to do it."

Luo Jia shook her head, "Optical fireworks have long been proven to be liars, and fireworks, fireworks, cannot explode and explode, are fireworks? "

"You can only do this for the Ministry of Chemistry. I have already decided to use hexamethylenetetramine! You can wait a moment, I'll send you an email."

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

Most Chinese people do not have body odor, so they are not very familiar with this thing.

But in other parts of the world, deodorants containing UluoTop are everywhere. There is no way. Who has caused foreigners to have problems with their evolution chain? Their odors are more serious.

In addition to removing body odor, hexamethylenetetramine can also be used as smokeless fuel, which has a very strong combustion effect, but will not produce smoke and dust.

Zhang Dongning was thinking, suddenly his phone was shaking slightly, and Luo Jia's email had arrived.

Zhang Dongning opened it and saw that it was a very complex chemical formula and synthesis steps.

{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 synthetic trimethylene trinitroamine, a very unstable explosive substance, commonly known as cyclone zhà yào, English abbreviation rdx.

However, after careful reading, it is not.

Luo Jia cleverly designed a model that was subzero and added hexamethylenetetramine, which successfully prevented the exothermic reaction. Without the exothermic reaction, nitric acid could not decompose and could not produce nitrogen oxides such as n2o.no2.

In short, through a series of complex chemical reactions and operations, we will eventually obtain a new type of combustion substance that is completely smoke-free but has a very explosive effect.

Its stability is also predictable. The only disadvantage is that it is relatively complicated to operate. Most operations must be carried out in an environment of 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 synthesis is completed, the final product will be very safe.

Zhang Dongning finally understood Luo Jia's design. He felt his hair standing on his back. In the past, he only knew that Luo Jia knew chemistry, but he didn't know that he knew so much and so deeply!

Are smokeless fireworks good to design?

Of course, it is not easy to design. If it is easy to do it, the chemistry community will have started. After all, China has a tradition of setting off fireworks. The ancient tradition that has been passed down for thousands of years has disappeared. People who are engaged in chemistry and making fireworks are always a knot in their hearts.

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

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

“First of all, it is the risk of synthesis.”

"This is easy to solve. Establishing an unmanned factory in remote areas and replacing artificial weapons with Xingchen Intelligent robotic arms. The robotic arms are highly accurate and very stable."

Zhang Dongning was stunned for a moment. He almost forgot that there is an almost invisible subsidiary of Xingchen Technology, Xingchen Intelligent.

Xingchen Intelligent makes nothing, specializes in robotic arms, and the products are only for use by the parent company.

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

As for why Xingchen Intelligent's mechanical arm is not taken out, it is because Luo Jia is worried that once this thing is sold in large quantities, workers will be unemployed, and China has not yet developed to the point where it can use machinery to replace people in full.

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

Luo Jia nodded, "That's true, so I plan to only make large fireworks, which will be set up by the public department. Anyway, fireworks are set up for viewing. As long as everyone can see them, it will bring the atmosphere up."

Zhang Dongning also said, "The third is the problem of dyeing agent. Fireworks cannot have only one color. New chemical compositions can only solve the problem of combustion, but cannot solve the problem of fireworks color. In addition, we have no experience in the design of fireworks."

Luo Jia said, "There is no problem with this. The dye and explosion effect are the patents of the fireworks factory. We directly acquire the largest factory in China and buy all their talents and patents."

After hearing Luo Jia's words, Zhang Dongning smiled and said, "If this is the case, then there is no problem. But I don't quite understand why I have to put out my energy to do this small project that obviously won't make any profit?"

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

"When I was young, every Lantern Festival on the fifteenth day of the first lunar month, fireworks would be set off in the city and in all courtyards. I took some money from my mother to buy some small fireworks, and got together with my companions to be happy all day. Such an atmosphere still makes me miss it."

"As society develops, traditions have become less and less. It's better to leave a little."

"It is said that fireworks are easy to cold, but I hope they will never be cold."

Zhang Dongning felt a kind of power from Luo Jia's words. He also thought of Luo Jia's speech. The real revival is not just the revival of economy and technology, but will inevitably return with the strength of culture and tradition to determine the world!

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