The military-industrial scientific research system of the academic master.

In the entire room, everyone's attention was instantly focused on Chang Haonan.

Even though the latter has been through many battles and has seen a lot, at this moment, he was also a little numb from being stared at by several blazing eyes.

However, after calming down, he still said in a deep voice:

"I thought of a device that can build a flood control belt in a short time. It can not only deal with urban waterlogging, but also prevent dam failures caused by floods to a certain extent, or help block and rescue dams that have collapsed. .”

"Ok?"

Upon hearing these words, Cao Gangchun's eyes instantly became sharp:

"Tell me more about it."

As the only one with a serious military background among everyone here, he has a more comprehensive understanding of the pain points in the process of flood fighting and rescue operations.

For an army in peacetime, disaster relief is a test of war.

And because disasters are more sudden and unpredictable, in some aspects the requirements for organizational and combat effectiveness are even higher!

Of course, in this regard, the People's Liberation Army has never disappointed.

Wherever there is danger, there are people's soldiers!

But just as soldiers need weapons and equipment on the battlefield, emergency rescue and disaster relief also require technology and equipment that keep pace with the times.

Although Cao Gangchun has worked in the headquarters for many years, he has also participated in several rescue operations for different types of disasters at the grassroots level, so he knows how difficult and risky it is in the absence of suitable technical equipment.

Chang Haonan nodded:

"Okay, give me a pen and paper."

Compared with previous research in the aviation field, this time, his overall idea was not complicated, so he made it clear in just a few sentences.

Only a little more attention was paid to the design of the steel frame used as structural support.

Because Cao Gangchun asked very detailed questions.

"Comrade Xiao Chang, the steel plate frame you mentioned is only used as a structure to accommodate the expansion bag. It does not itself play a role in blocking the water flow, right?"

"Yes, you can think of this thing as a reinforced steel cage, and the expansion bags are gravel bags and sandbags that are lighter and easier to move."

Although Chang Haonan is not a soldier, he is still someone who has experienced various propaganda in the information age. He can understand the other party's urgent but worried mentality at this time, so he explained very patiently.

After hearing this, Cao Gang finally let go of his worries.

It’s not that they don’t trust each other, it’s just that they are separated by mountains. People who have no idea about the power of floods can easily come up with some unreasonable methods such as “use a metal wall to block the flood”.

"So, what should be used as the absorbent material in the expansion bag you mentioned?"

In the end, Cao Gangchun still raised this most critical question.

“That’s exactly what I want to ask the organization to address.”

Chang Haonan glanced at the circle of big guys in front of him and said solemnly:

"I have read a document before, which talks about a highly water-absorbent powdered resin obtained due to process errors. The water absorption performance is about 1000:1-20. The content of the report is that the manufacturer originally just used it. When ordinary non-hazardous solid waste was piled in the open air, after a heavy rain, the entire pile was filled with water-absorbed resin."

"It would be very difficult to go back and find this document now, so I would like to apply to conduct a thorough investigation of chemical companies across the country to see if any manufacturer has produced products with similar properties."

"I already have the design of the expansion bag and the steel plate frame. It won't take too long. As long as the problem of water-absorbent materials is solved, it can be put into production immediately!"

As soon as these words came out, Cao Gangchun beside him could no longer sit still, stood up and said:

"I can't wait any longer. One more second of delay in this matter will make it more difficult for the troops involved in disaster relief. I will go back and report it immediately, contact the Ministry of Chemical Industry, and ask them to issue orders to chemical companies nationwide. Send a notice and be sure to find this material!"

The purpose of this meeting was originally to solve the risk of waterlogging faced by Factory 132. Now that Chang Haonan has proposed a solution, there is no need to continue to waste it.

"Xiao Chang, after the expansion bag and steel plate frame are designed, you must contact me as soon as possible. I will notify the quilt factory and machinery processing factory in the military industry system later, so that they can be ready to switch production at any time."

Although Ding Gaoheng's reaction was not as exciting as Cao Gangchun's, one could hear some urgency from his speaking speed, which was much faster than usual.

"Old Cao."

Huai Guomo stood up from behind, stopped Cao Gangchun, who had already put on his hat and was about to go back to deploy the mission, and handed him a piece of paper in his hand.

He is from the Chemical Engineering Department of Jiaotong University. Although he has not participated in any specific chemical engineering projects for several years, he has still not forgotten some of the basic skills he learned in the past. He has been silent just now and is deducing the possible composition and synthesis based on the material properties described by Chang Haonan. route:

"According to my analysis, the material Comrade Xiao Chang mentioned should be some kind of cross-linked polymerization product using acrylic acid or acrylate as one of the raw materials. You can tell the Ministry of Chemical Industry to focus on the chemical industry in this field. Inside the business.”

"it is good."

Cao Gangchun took the piece of paper filled with element symbols and chemical structural formulas.

He, who graduated with an artillery major, couldn't fully understand it, but that didn't matter.

As the people in this conference room returned to their jobs, orders were issued in an orderly manner to all parts of the country, and together with the People's Liberation Army soldiers who were gathering across the country, they were preparing to fight against the natural disaster that lay ahead.

The huge and sophisticated state machine began to show its power at critical moments.

Even if it's only part of it.

That night, dozens of military factories located along the Yangtze River, Nenjiang River and Songhua River received instructions from their superior units, asking them to immediately enter production mobilization status and be ready to switch to production of a polyester made of high-strength chemical fibers. layers of sealed bags, and a steel structural frame with a size between 2-3 meters that can be quickly assembled by bolts.

Later, textile and steel companies in these regions also received similar notices, requiring them to suspend orders at hand and give priority to providing raw materials to a group of nearby military factories that have not had much production tasks for many years.

Early the next morning, Army aviation units near Gan and Hubei provinces received orders to take off, weather permitting, to conduct aerial reconnaissance of the local disaster situation.

Twelve hours later, a research team from Zhejiang University launched a stratospheric airship carrying communication relay equipment on the border of Hubei and Shaanxi provinces.

It was the ship that was responsible for providing communications relay for naval aviation aircraft carrying out embankment operations in southern Qiong Province a month and a half ago.

……

On the third day, Chang Haonan, who had stayed up for two nights in a row, handed the detailed design plan of the flood control expansion bag and steel structure frame to Ding Gaoheng's desk.

Relevant comrades from the General Office of the Science and Technology Commission have already been waiting here. They will formulate the design plan into production standards in the shortest possible time and distribute it to various arsenals that are already ready.

"Director Ding, the kind of material I mentioned..."

Chang Haonan didn't have much time to pay attention to what was happening outside these days, so he was a little worried about it.

"Already found."

Sitting next to him, Huai Guomo picked up a report from the table and handed it to Chang Haonan:

"Last night, the Ministry of Chemical Industry received a report from a chemical factory in Kecheng, Zhejiang Province, stating that they had unintentionally added starch, acrylic acid and cross-linking agents together, and then added alkali to decompose them after graft polymerization. A large amount of waste products that were not pure enough but highly absorbent were produced, and it took a lot of effort to process those things.”

Chang Haonan took the report and glanced at it quickly.

He doesn't have much background in chemical engineering, but he can still understand the conclusion.

The water absorption capacity is about 1000:5-10, which meets the requirements.

The main raw materials are starch, acrylic acid and sodium hydroxide, which have almost no requirements on purity, and the cost is no problem.

More importantly, this factory is already producing polyolefins using a similar graft polymerization process and can complete the conversion in a relatively short period of time.

"Great!"

Chang Haonan flicked the report in his hand:

"In this way, we can reduce a lot of physical burden on our soldiers participating in flood fighting and rescue missions, and the damage caused by waterlogging in major cities will be easier to control!"

"Yes, when Lao Cao found me this morning, he almost jumped up."

Ding Gaoheng put the report back on the table:

"This thing you designed may seem inconspicuous, but its significance to the country and people is no less than those previous achievements. I think it must have a resounding name."

"In the mythology, Dayu holds four innate treasures. I think it would be better to name them after one of them that is related to flood control."

"Just call it 'Nine Heavens Breathing Soil'!"
