Jin Chen went back to write the report, and Mu Tianyu was ready to contact Yang Bin.

It's been a long time since Mu Tianyu got in touch with Brother Bin.

Especially since Zhang Letong's death, Mu Tianyu has not been in the mood to contact the outside world.

He was afraid of the concerned and worried eyes of his friends and family. He was also afraid that he would be comforted when they met, which would make him and the other party sad again.

So since Zhang Letong's condolence activities ended, Mu Tianyu has been in touch with everyone for a long time. He wanted to wait for everything to pass, forget about it, and then contact everyone.

Now, in order to confirm his good brother Jin Chen's idea, it is practical. He needs to ask Brother Bin for help. Only when the experts of the Academy of Military Sciences have demonstrated that it is feasible and have developed a special fire extinguishing bomb for anti-materiel guns with ultra-high efficiency can they reach the practical level.

"Hello Brother Bin, I'm Mu Tianyu."

"Tianyu, I haven't been in touch for a long time, I miss you very much."

"I miss Brother Bin very much, but I don't want to disturb Brother Bin as a last resort."

When Yang Bin heard this, he immediately felt nervous in his heart, thinking that Mu Tianyu shouldn't be so unlucky, why did he encounter any disasters?

"Tianyu, tell me quickly, what's going on?"

"Brother Bin, don't worry, I'm fine, nothing happened. I just want to ask Brother Bin for help, can you demonstrate the feasibility of using fire extinguishing bombs with anti-equipment weapons. This is an idea put forward by Jin Chen, and I think it is feasible, so I ask Brother Bin to analyze the feasibility of giving us an analysis from the perspective of a weapons expert, and whether we can produce a matching fire extinguishing bomb. ”

Yang Bin breathed a sigh of relief when he heard that Mu Tianyu was fine.

However, it was a little difficult to hear about the problems of anti-materiel weapons and fire extinguishing bombs. This is because the anti-materiel weapons are basically counterfeit products produced in China, and there are very few specifications and varieties. If you import it, the cost is very high.

Moreover, the fire extinguishing bomb problem raised by Mu Tianyu has not yet been perfected.

However, at this time, Mu Tianyu couldn't see Yang Bin's expression. In his heart, his brother Bin is omnipotent. Whatever the weapon, he should be able to get it.

Even if he really can't get it, he will definitely be able to make it himself.

The issue of cost, compared to the damage caused by fire, is simply a drop in the bucket. Especially when the fire of ultra-high buildings and important facilities needs to be extinguished in a very short time, if the automatic fire extinguishing system on the site happens to fail, or the automatic fire extinguishing system cannot solve the problem normally, it is absolutely feasible to extinguish the fire remotely and accurately.

One example is the famous September 11 attacks, which killed more than 2,900 people in a series of terrorist attacks on the World Trade Center in New York on September 11, 2001.

A total of 343 firefighters died.

On the morning of September 11, 2001, from 8:46 a.m., when the World Trade Center caught fire, to 10:29 a.m., when the World Trade Center completely collapsed, there was a total of 103 minutes of rescue time.

In this life-and-death hour and 43 minutes, if the fire brigade had put out the fire in a timely and accurate manner, what would the result look like?

For example, is it possible to use a helicopter to drop fire extinguishing bombs to extinguish the fire?

For example, is it possible to use an anti-materiel gun to fire a fire extinguishing bomb to accurately extinguish the fire and cool down?

With such a huge war machine in the United States, it has all kinds of advanced weapons. But the equipment of the American fire brigade has never been ahead of the world.

Yang Bin did not put down Mu Tianyu's phone, he thought that our Chinese army is the people's army, for the sake of fire rescue, we can increase investment, so that the fire brigade is equipped with the world's most advanced fire equipment and equipment.

Yang Bin, who was already a major general, did not talk about difficulties, he didn't want to disappoint his beloved little brother, he immediately agreed: "Tianyu, don't worry, leave it to me, I will send the sample to Jiangcheng later." ”

"Really? Thank you so much, Brother Bin! ”

"Xiaoyu, didn't you say it, we don't need to say thank you."

"Well, well, Brother Bin, I want to drink with you."

"Okay, okay, the next time we meet, we'll get drunk."

"Huh? Brother Bin, I think it's better to drink our rice bar in Jiangcheng, haha, how dare I drink with Brother Bin! ”

"Heh, heh, Xiaoyu, don't be modest. By the way," Yang Bin suddenly thought that he had been studying the ultra-fine dry powder fire extinguishing agent for a long time, so he asked: "I have studied the ultra-fine dry powder fire extinguishing agent before, and I want to ask, do you use it more in actual work?" ”

Mu Tianyu immediately thought of the relevant literature: the British KIDD company, in the seventies, used spray drying technology to develop a particle size of less than 5 microns, potassium bicarbonate ultra-fine and efficient dry powder fire extinguishing agent.

This ultra-fine dry powder has been shown by the total submerged fire extinguishing test to show that the fire extinguishing efficiency is 10 times that of the general fire extinguishing agent.

However, due to the complex equipment and process requirements required, it has not been popularized and applied so far.

In 1997, only a fire-fighting equipment company in Jiangcheng began the research of ultra-fine dry powder, and used jet milling technology to prepare an ABC ultra-fine dry powder fire extinguishing agent that can be overall moisture-proof, can ensure good powder fluidity, no moisture absorption, no agglomeration, and high fire extinguishing efficiency without siliconization.

However, 90% of the dry powder that can be obtained is less than 10 microns in size, and the average particle size can only be close to 5 microns.

But even so, the minimum fire extinguishing concentration of this ultra-fine dry powder is only 65 grams per cubic meter, and it is non-toxic and harmless, non-corrosive to objects, non-irritating to the human respiratory tract, and has high insulation.

It was not until 2012 that Jiangcheng took the lead in transforming the ultra-fine dry powder fire extinguishing theory into products and achieving mass production in the country, but due to a variety of reasons, it is still not widely used.

At present, ultra-fine dry powder fire extinguishing agent fire extinguishing appliances have begun to appear on the market, which is completely different from ordinary dry powder fire extinguishers.

Because the particle size of the fire extinguishing agent powder is less than 5 microns, the displacement energy value (ODP) of atmospheric dissipation is zero, and the substitute energy value (GP) of room temperature effect is zero, and its fire extinguishing efficiency is 6 to 10 times that of ordinary ABC dry powder fire extinguishing agent, 10 times that of heptafluoropropane fire extinguishing agent, and more than 15 times that of carbon dioxide.

This is the one with the highest fire extinguishing effectiveness and the lowest concentration among the fire extinguishing agents identified in the world.

Moreover, the fire extinguishing agent is non-toxic, harmless, non-irritating to human skin and respiratory tract, and non-corrosive to protective objects; It does not decompose, does not absorb moisture, does not agglomerate under normal conditions, and has good fluidity, diffusibility and electrical insulation.

The most amazing thing is that this ultra-fine fire extinguishing agent can realize automatic fire extinguishing and local protection fire extinguishing by full submersion.

Of course, the only deficiency of the fire extinguishing agent is that after the fire is extinguished, dust will be left on the site, although the scene is very easy to clean after the fire is extinguished, and it can be removed with a vacuum cleaner or brush, and there is no impact on the equipment and instruments. But after all, it's still a regrettable little drawback.
