Chapter 597 Steel Quality Meeting
In fact, the third generation of tear gas also uses an explosion method to spread more capsaicin. To put it bluntly, the principle is the same as when Gao Zhendong was a child and wrapped chili noodles around firecrackers.
Because capsaicin and dihydrocapsaicin, which account for most of the components of natural and synthetic capsaicin, have a big problem, that is, pyrolysis, and this pyrolysis occurs relatively easily.
This pyrolysis can occur in an extremely wide and easily accessible temperature range of 265-425°C. The ratio of pyrolysis between the two can be as high as more than 90%, and a lot of things can be released, but it is not capsaicin.
This is very embarrassing, which means that the way to generate smoke by thermal dispersion method is basically cut off.
"As for the third thing, the chili pepper itself is not enough. If you don't eat enough, how can you eat enough?"
Chili peppers take up cultivated land. The priority for planting these days must be grains and vegetables. Chili peppers are not a condiment eaten by the whole country, and they are not a necessity. Naturally, the yield is not too high.
Haha, this reason is really too powerful.
Lecturer Zhang was thinking as he was eating rice in his mouth. It seemed that Gao Zhendong meant more than just OC as a tear-jerker.
"Professor Gao, besides OC, what other suitable tear gases are there?"
Well, Citigroup has already chosen it.
Gao Zhendong smiled and said: "My suggestion is to use CS (o-chlorobenzylidenemalononitrile)."
"CS?"
The generation of tear gas is basically based on tear gas. CS is called the second generation of tear gas. Its characteristic is that it is less toxic and more efficient than CN.
Gao Zhendong probably explained to Professor Zhang: "The Citigroup used to use CN (chloroacetophenone). We suffered a lot from this in the tunnels back then, which is why I considered it. But this kind of There is a problem with tear gas. Inhaling large amounts can cause death, and the stimulating effect is not as good as CS.”
Under a certain amount of inhalation, the main sequelae of CS is dermatitis.
Is this good stimulation effect the main reason why you chose CS? Lecturer Zhang complained in his mind, but did not say it out loud. It would be inappropriate to say such words.
No matter how much Professor Zhang is obsessed with academics and is not very good at interpersonal communication, he still won't say such stupid things.
"Is it expensive? Is it easy to use?" Based on the previous experience, Professor Zhang only asked these two questions.
When it comes to this, Gao Zhendong gets excited.
"It can be synthesized using o-chlorobenzaldehyde and malononitrile as raw materials."
Well, the name of this reactant is short, so it should be simpler. Lecturer Zhang, who was slightly shocked by Gao Zhendong's use of OC's "3-methoxy-4-hydroxybenzylamine hydrochloride", quickly learned it. Similar to the simple way of thinking of "three long and one short choose the shortest".
"It would be best if it could be synthesized directly."
"And it can be synthesized industrially." Gao Zhendong told her the good news.
Industrial synthesis and laboratory synthesis are two different concepts.
Laboratory synthesis means that this thing is available, but whether it can be mass-produced and used is often limited by cost, conditions, environment and other reasons, and may not be satisfactory.
The most extreme example is those artificial elements with extremely short half-lives, which must be blasted with particle accelerators. The cost is high and the yield is extremely low. Moreover, those with short half-lives must be calculated in milliseconds, which is not practical.
Industrial production means being able to produce a large number of stable target products at one time. This is the tear gas that Lecturer Zhang needs.
"Then how do you spread this thing?"
"This is simple. This thing can be made into a smoke type using the thermal dispersion method, or it can be made into an explosive type using the explosion method, or it can be thrown using a powdering device."
The ease of use greatly aroused the interest of lecturer Zhang.
Thermal dispersion and explosive throwing are her areas of expertise.
"Professor Gao, I want this, I want this." It's cheap, can be synthesized industrially, and is easy to use. This is much easier to service than capsaicin.
As for whether it is natural or not, whether it is environmentally friendly or not, I believe that everyone does not pay much attention to it. This is a non-lethal weapon, and that alone is humane enough. What else is needed for a bicycle?
"Okay, then you can design according to CS. As for the specific synthesis process of CS, you can ask me for it when the time comes."
Gao Zhendong knows the synthesis process of this thing, and it is an optimized process with good cost, yield, and product quality.
Although it is not specific at the level of process documents, I can remember the overall route, what drugs are used, and what reaction methods are used, so I don’t need to waste lottery opportunities to search. Even if the search price is cheaper now, things like tear gas are not likely to be enough. The level at which the price is spent.
I believe that with these things, comrades in the chemical industry can restore the industrial synthesis process of CS at a very low cost.
But he couldn't write it out silently on the spot, that would be a bit too scary.
Lecturer Zhang didn’t take it seriously. It was okay to discuss tear gas, but it was really inappropriate to discuss the synthesis process of tear gas in the cafeteria. Hey, this thing went too smoothly. I feel like I took advantage of Professor Gao.
How about, in the name of experiment, get him some chili pepper? It seems like he likes chili peppers.
I just don’t know what Professor Gao does. It seems that his major is electromechanical, but he is also involved in firearms and ammunition. Now it seems that he is so proficient in chemical engineering. It is really amazing.
You must know that Lecturer Zhang originally asked Gao Zhendong for advice, just to get some advice on throwing methods and types of tear gases, especially tear gas charges.
But even the synthesis process of tear gas can be obtained, which she did not expect. How to look at this thing, Professor Gao should not be able to know it, this major is the leader.
Gao Zhendong: Don’t be a bull in basic practice.
——
Gao Zhendong, who was working in the third factory, received a very rare but funny meeting notice.
The rare reason is that as a member of the 17th Machinery Department, Gao Zhendong rarely participates in the technical meetings of this department.
This is why it is funny. As the winner of a lot of technical awards from the 17th Machinery Department, he rarely participates in the technical meetings of the 17th Machinery Department. This seems to be quite incredible no matter what. matter.
Maybe the leader of the 17th Machinery Department thought about it and felt that this was a loss. No, he had to be called.
The topic of the meeting was quite interesting, which was the discussion on the steel quality issues of the previous year.
Let’s talk about this, tut tut tut…
In this regard, Gao Zhendong's idea is relatively simple. You can participate, just give a speech. I am engaged in new materials, new processes, and new technologies. I know a little bit about safety, but I am not familiar with the quality.
Sitting in the venue, looking at all kinds of technical experts gathered in the venue, Gao Zhendong was quietly hiding in the corner, not communicating about this matter.
When the leader of the Seventeenth Machinery Department saw Gao Zhendong Cat in the corner, he smiled slightly. This guy has a bright mind and is very sensitive.
But if you want to hide, ahem, you can't escape.
The leader did not call him out for the time being. This meeting was not held for Gao Zhendong alone. It would not be good for him to call him out from the beginning.
The meeting went on as usual, with introductions, reports, speeches, and yes, scoldings.
Well, people at this time are more enthusiastic.
The thing actually sounds very simple. Steel production increased significantly last year, but the quality can be compared with a word that Gao Zhendong often said when talking about steel quality issues in his previous life - strip steel.
Even Ditiao Steel still has the word steel in its name, but at this time, some products are not even close to steel.
This problem is not a problem for the third rolling mill. They are not steelmaking plants and have no steelmaking tasks. As for their limited production of special alloys and some special materials, they are closely watched, and many people are concerned about it.
Besides, as far as Gao Zhendong knows, those quality problems basically have nothing to do with regular large factories such as Beijing Steel Plant and No. 3 Rolling Plant.
So he just listened. The discussion was very lively and many solutions were proposed.
Gao Zhendong listened for a long time and learned a lot. You can really learn something from this kind of meeting, and everyone who participated in the meeting knew something.
The leader of the 17th Machinery Department saw that everyone had talked a lot, but Gao Zhendong still looked like he was studying hard, and he couldn't help but secretly praise this little slick guy.
But now that he's here, it's impossible to come out without some practical information. The leader is not interested in Gao Zhendong's evaluation of the past, nor does he want him to do this, but he wants to hear Gao Zhendong's outlook on the future.
While a comrade was finishing his speech, the leader of the 17th Machinery Department smiled and knocked on the table: "Comrade Gao Zhendong, what do you think? Tell me your opinion?"
The name was directly called. As a person who holds more than two-digit Agni Technology Award, Gao Zhendong has not spoken. This has made everyone feel strange. Chief Engineer Gao seems to be not very active today.
Only the direct instructions from the leader of the 17th Machinery Department made everyone feel somewhat normal. In this situation, there was something to be said anyway.
Gao Zhendong had to put down the pen he was recording in his hand. He was not holding the pen to pretend to be diligent, but there was indeed a lot worth learning and recording.
It seems there is still no way to escape, Gao Zhendong thought to himself.
He thought for a while, and an idea from a long time ago came to his mind.
The thing is a good thing, but he didn't dare to take it out before. It's an old problem that can't be explained, not even a genius can explain it.
This is a result that must rely on a large amount of actual work experience in the steel industry, as well as the collection of large amounts of data and scientific analysis.
No problem now. This thing looks very simple, but it is very useful. It has guiding significance for the production process of various steels. It can effectively improve production efficiency and product quality, save costs, and is very universal.
In Gao Zhendong's previous life, when talking about people's livelihood, he usually mentioned two basic materials-fertilizer and steel.
