Chapter 158: Fire extinguishing can be done, but explosion suppression is not enough (3k)
When Gao Zhendong said this, Liu Wenwu was so happy. Look, what is the original designer? In his hands, a Problem, there are easily several solutions.
"I estimate that if all the methods I mentioned above are used, the reaction time can be compressed to the order of 10 milliseconds."
On the order of 10 milliseconds, not 10 milliseconds , 10~90 milliseconds can be called 10 milliseconds.
This made Liu Wenwu overjoyed. This was enough.
"This speed is enough, Director Gao, can you be more specific?"
Gao Zhendong smiled: "Actually, our factory can produce the electrode materials and hand them over to you, and you can configure the protective cover. Tube. These are the ways. You can try them one by one."
"The most convenient material for the protective sleeve is copper. Among metals, the thermal conductivity is second only to silver, but it is only about 5% lower. From a comprehensive perspective of price and mechanical properties, copper is a good substitute."
"As for the specific thickness, you can test it yourself and get a comprehensive value that meets the requirements."
Liu Wenwu nodded repeatedly and wrote down Gao Zhendong's suggestions.
Gao Zhendong thought for a while and pointed out another way, although the conditions were not yet mature yet.
“Actually, using thermocouples is not the best way, but now other methods are not very mature and are not as good as thermocouples. To use thermocouples, it is recommended to arrange multiple sensors in a distributed manner or use cable-type thermocouples. , because strictly speaking, thermocouples must 'touch' heat to be effective, that is, there must be contact. If the number is small, the temperature distribution in the protective space cannot be completely monitored. ”
Liu. Thinking about it, Director Gao's words made sense.
Thermocouples need to be in direct contact with heat to drive their own temperature to rise, and then start spraying fire extinguishing agent when the temperature reaches the threshold. If the number is small, the situation mentioned by Director Gao will definitely occur.
After writing down the words "systematic arrangement, decentralized arrangement", he suddenly realized that Director Gao seemed to be saying that he had a better way. No matter whether it is mature or not, just listen first. Always right.
Isn't this a bit too much? With a little anxiety, Liu Wenwu said: "Director Gao, what you just said is a better way."
Gao Zhendong nodded: "I was about to tell you this, using a thermocouple, that The reaction speed can be achieved by automatic fire extinguishing, but explosion suppression is not that interesting. Liu Gong, what do you think is the fastest way for us to receive information?"
Liu Wenwu thought about what Gao Zhendong said about thermocouples just now. The metaphor used when talking about the disadvantages of "touch".
Touch, smell, listen. That’s right! He suddenly understood: the fastest thing is to "see"! !
Liu Wenwu reported in one breath: "Director Gao, look! Look is the fastest."
But then, he was a little frustrated. The price of a sensor that could 'see' was very high at this time: "Director Gao, is it inappropriate to use a camera or something like this?"
Gao Zhendong smiled: "We say 'see', but actually the core principle is the detection of electromagnetic waves, which is the fastest. You don't necessarily need visible light, you have to know that flames will emit infrared rays of special wavelengths, and they will also reflect and It illuminates every inch of the space where it is located."
Liu Wenwu suddenly realized: "It is a great idea to install an eye that detects special wavelengths of infrared rays inside the protective target!"
As long as there is one! When there is a fire, there is no need to wait for the temperature to hit, the fire extinguishing and explosion suppression system has already activated.
You must know that when a tank is penetrated, the speed from fire to explosion is very fast. If the action is delayed by 10 milliseconds, things may be out of control.
Liu Wenwu, who suddenly felt that the world was widening, suddenly felt refreshed. What is Dana? This is Dana. You want to solve the problem, right? It's easy to say, and I'll give you a better one.
Gao Zhendong shook his hand: "Don't be too happy yet. This technology is still not very mature yet. The false alarm rate is relatively high and it is also greatly affected by external light sources. However, you can use a thermocouple to top it first. This technology is slowly developing, and when it is well developed, it is just a matter of replacing the sensor. It is simple and the cost is not high."
Liu Wenwu nodded repeatedly: "Director Gao is right, let's solve it based on the existing technology. If there are any problems, at the same time, we will study better technologies to solve the problems.”
Gao Zhendong gave him another tip: “As for eye problems, you can try to talk to people at the Institute of Guidance and Research. I can't tell you anything about them. You can only try your luck or see if you can coordinate with your superiors."
Liu Wenwu still understands the confidentiality rules and can. Getting this news is already the maximum. Director Gao said there will be gains, and there will be gains!
Liu Wenwu is already a little superstitious about Gao Zhendong.
Liu Wenwu remembered another thing: "Director Gao, we still have a problem."
He was very embarrassed to say this, feeling that he was a bit greedy.
Gao Zhendong smiled: "You can say it, but first, I don't know everything, maybe you will be disappointed."
Liu Wenwu felt even more ashamed, Liu Wenwu Ah Liu Wenwu, you are treating Director Gao as a wishing fountain.
But after he had said it all, he still asked: "That's it, Director Gao, your factory has been dealing with fire sources for a long time, so fire prevention and extinguishing must be put first. I want to know if there is anything that is efficient in eruption." It is a fire extinguishing agent that is fast, has low residue, is less harmful to people if inhaled directly, and the harm will basically not last for a long time. Ah, by the way, the type of fire extinguishing should be suitable for our purpose." Liu Wenwu almost gave up after saying this. You're such a big talker, look at what you're asking. With so many restrictions, is it that your position as Director Gao only serves you?
Unexpectedly, Gao Zhendong thought about it and actually answered him.
“Haloalkane fire extinguishing agents can be used. This type of fire extinguishing agent is different from the suffocation fire extinguishing method, cooling fire extinguishing method and isolation fire extinguishing method of general fire extinguishing agents. It directly participates in the combustion reaction and eliminates free radicals in the combustion. , destroying the combustion reaction, in terms of fire extinguishing principles, is the most suitable for your needs. Moreover, it does little harm to people and has no subsequent harm. "
"Alkane halogenation?" This is completely beyond the realm of possibility. Liu Wenwu's knowledge reserve has been improved.
"Well, it is a product in which the hydrogen atoms in the alkane organic molecules are replaced by halogen elements. You can use bromochlorodifluoromethane, bromotrifluoromethane, dibromotetrafluoroethane, etc."
Gao Zhendong was very thoughtful and did not use Halon-1211, 1301, and 2402 to introduce these halogenated alkyl fire extinguishing agents, but directly explained their chemical names.
This means that the structures of these alkyl halides are very simple. People with some basic knowledge of organic chemistry will know what they are at a glance. Otherwise, they would not know what they are just by looking at the chemical names.
Comrades who have studied organic chemistry in college know that naming organic substances is not a big difficulty in exams, but it can be considered a bit of a torture.
However, these fire extinguishing agents are not all beneficial. For example, they all cause great damage to the ozone layer. However, in tank fire extinguishing and explosion suppression systems, this is obviously not a point that needs to be considered.
Liu Wenwu was amazed by Director Gao's knowledge. He even knew chemistry. Is this the realm of a great person?
Actually, Gao Zhendong knows shit about chemistry. As I said before, it is all accumulated from being an Internet troll in his previous life, plus his enhanced brain is super good.
Who said keyboard warriors are not heroes?
Liu Wenwu felt that this trip was really fruitful. It can be said that after this trip, the automatic fire extinguishing and explosion suppression system he was responsible for was basically completed.
Seeing that Liu Wenwu's matter was almost finished, Gao Zhendong looked at his watch and said with a smile: "Liu Gong, it's already noon. Come on, come on, I'll treat you to a meal."
After saying that, he called out to the people from the single crystal furnace research team, and treated him to a treat, and the single crystal furnace research team started work, and everything was ready.
On the way to the cafeteria, Liu Wenwu remembered Mr. He's instructions: "By the way, Director Gao, our Mr. He asked me to give you a message, saying when the things will be available."
When Gao Zhendong heard this, he thought, Haha, Mr. He is thinking about the stability of tanks and artillery. The total progress is also very fast.
He smiled at Liu Wenwu and said: "Haha, go back and tell Mr. He, it's almost time."
In fact, it's almost done, but this thing cannot be brought back through Liu Wenwu.
What Mr. Luo brought back last time was, firstly, because there were only a few pages of catalogues, and secondly, Mr. Luo was of sufficient rank and reasonable.
But this time it is a complete thing. It is not appropriate to ask Liu Wenwu to take it back. It is better to take the confidential channel.
Liu Wenwu didn’t know what the two of them were talking about, but when he heard Gao Zhendong say something fast, it meant that what Mr. He wanted should have good results, and it would be easy to communicate with Mr. He when he returned. .
As for the stupid thing about helping to bring things back, he didn't mention it at all.
Liu Wenwu ate, left the No. 3 Steel Rolling Plant, and turned back to the Guidance Research Institute. Director Gao said that there will be harvest here, then there will be harvest. If there is no harvest, it will be me. Wrong harvesting method.
The people at the Guidance and Research Institute are very enthusiastic towards them. At this time, they are of one mind and the whole country is playing a game of chess. It is quite real and there are not so many taboos between them.
When hearing Liu Wenwu's request, the Guidance and Research Institute was a little embarrassed: "Comrade, I need to ask for instructions on the situation you mentioned."
Then the matter was reported The vice president of the Institute of Guidance and Research, who is also the model chief engineer of infrared air-to-air missiles, went there.
“Have they said specifically what kind of support they want?” The model chief pondered.
“No, I just told them about their situation and see if we can provide support. As for what they want, we didn’t say anything specifically.”
"It seems that the person who gave him the information was very cautious and did not reveal too much."
"According to him, they came here just after receiving technical support from the third steel rolling mill."
The chief model engineer suddenly became energetic: "Huh? The third rolling mill in Beijing? Where is director Gao Zhendong?"
"It should be director Gao's place. Apart from him, the third rolling mill Others are unlikely.”
