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

Rao is latter has been through a lot of battles, and at this moment, he is also staring at several blazing eyes a little numb.

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

"I came up with a device that could build a flood barrier in a short period of time, which could not only deal with urban waterlogging, but also prevent dam failures caused by flooding to a certain extent, or help to plug and rescue the mouth of a dam that has collapsed."

"Huh?"

Hearing this, Cao Gangchun's eyes instantly became sharp:

"Tell me more."

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

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

And because the disaster situation is more sudden and unpredictable, in some respects the requirements for organization and combat effectiveness are even higher!

Of course, in this regard, the PLA has never disappointed.

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

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

Although Cao Gangchun has worked in the headquarters for many years, he has also participated in several rescue operations in different types of disasters when he was at the grassroots level, so he is well aware of the degree of hardship and risk in the absence of appropriate technical equipment.

Chang Haonan nodded:

"Okay, give me a pen and a piece of paper."

Compared with previous research in the field of aviation, this time, his general idea is not complicated, so it is clear in just a few sentences.

Only a little more tongue-in-cheek was spent on the design of the steel plate frame used as the structural support.

Because Cao Gangchun asked in great detail.

"Comrade Xiao Chang, the steel plate frame you mentioned is only used as a structure to accommodate expansion bags, and it does not play a role in blocking the flow of water, right?"

"That's right, you can think of this thing as a reinforced steel cage, and the expansion bag is a lighter, easier to move gravel bag and sandbag."

Although Chang Haonan is not a soldier, he is also a person who has experienced all kinds of propaganda in the information age, and he can understand the other party's urgency at this time, but he is worried about the state of mind of empty joy, so he explained very patiently.

Hearing this, Cao Gangchun's hanging heart finally let go of most of it.

It's not that they don't trust each other, it's really like a mountain across the line, and it's really easy for people who have no concept of the power of the flood to come up with some anti-heaven solutions such as "blocking the flood with a metal wall".

"So, what should be used for the absorbent material in this expansion bag?"

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

"That's exactly what I want to ask for an organizational solution."

Chang Haonan glanced at the circle of bigwigs in front of him, and said solemnly:

"I read a literature before, which talked about a superabsorbent powdered resin obtained due to process errors, and the water absorption performance is about 1000:1-20 range, and the content of the report is that the manufacturer originally just regarded it as a general harmless solid waste and piled it up in the open air, but after a heavy rain, the entire accumulation field was filled with resin after water absorption."

"Now I want to go back to find this document, I'm afraid it's very difficult, so I want to apply to conduct a thorough investigation of chemical companies across the country to see if any manufacturer has ever produced products with similar properties."

"I basically have a draft of the expansion bag and the design of the steel plate frame here, it doesn't take too long, as long as the problem of absorbent materials is solved, it can be put into production immediately!"

As soon as these words came out, Cao Gangchun next to him couldn't sit still anymore, stood up and said:

"I can't wait any longer, if this kind of thing is delayed for one more second, it will make it difficult for the troops involved in the disaster relief for one more second, I will go back and report it immediately, contact the Ministry of Chemical Industry, and ask them to issue a notice to chemical companies nationwide, and they must find out this material!"

The purpose of this meeting was originally to solve the risk of waterlogging faced by the 132 factory, and now that Chang Haonan has proposed a solution, there is naturally no need to continue to dry up.

"Xiao Chang, after the design of the expansion bag and the steel plate frame is out, you must contact me as soon as possible, and I will notify the clothing factory and the mechanical processing factory in the military industrial system later, so that they can be ready to change production at any time."

Although Ding Gaoheng's reaction was not as excited as Cao Gangchun's, he could also hear a bit of urgency from his much faster speed than usual.

"Lao 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 a piece of paper in his hand to the other party.

He is from the Department of Chemical Engineering of Jiaotong University, although he has not participated in a specific chemical project for some years, he has not forgotten some basic skills learned in the past, and he has not opened his mouth just now to deduce the possible composition and synthesis route according to the material properties described by Chang Haonan:

"According to my analysis, the kind of material mentioned by Comrade Xiaochang should be the product of cross-linking polymerization with acrylic acid or acrylate as one of the raw materials, and you can tell the Ministry of Chemical Industry to focus on chemical enterprises in this field."

"Okay."

Cao Gangchun took the piece of paper full of elemental symbols and chemical structures.

Having graduated from artillery, he can't fully understand it, but it doesn't matter.

As the people in this conference room returned to their posts, one order after another was issued to all parts of the country in an orderly manner, and together with the PLA soldiers who were gathering around the country on standby, they were preparing to fight against the natural disaster in front of them.

The vast and sophisticated state apparatus began to show its might at a critical moment.

Even if it's only partial.

In the evening of the same day, dozens of military factories along the Yangtze River, Nenjiang River, and Songhua River received instructions from their higher-level units, telling them to immediately enter a state of production mobilization and be ready to switch to a multi-layer sealed bag made of high-strength chemical fiber, and a steel structural frame with a size of between 2 and 3 meters that can be quickly assembled by bolts.

A little later, textile and steel companies in these regions received similar notices, asking them to suspend their orders and prioritize the supply of raw materials to a group of nearby military factories that have not had much production for many years.

In the early morning of the next day, army air units near Jiangxi and Hubei provinces received orders to take off if the weather permitted to conduct aerial reconnaissance of the damage in the area.

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

That is, a month and a half ago, the one that was in charge of providing a communications relay for naval aviation aircraft carrying out embankment operations in the south of Qiong province.

……

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

The relevant comrades of the General Office of the Commission of Science and Technology have been waiting here for a long time, and they will formulate the design plan into production standards in the shortest possible time and distribute it to the various arsenals that have long been ready.

"Director Ding, the kind of material I'm talking about ......"

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

"I've found it."

Huai Guomo, who was sitting next to him, 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, saying that they had inadvertently added starch, acrylic acid and crosslinker together, and after grafting polymerization, alkali decomposition, produced a large number of waste products with insufficient purity, but strong water absorption, and it took a lot of effort to deal with those things."

Chang Haonan took the report and glanced at it quickly.

He doesn't have much knowledge of chemical engineering, but he can still understand the conclusions.

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

The main raw materials are starch, as well as acrylic acid and sodium hydroxide, which have little to no requirement for purity, and the cost is no problem.

What's more, the plant was already producing polyolefins using a similar graft polymerization process, which could be converted in a relatively short period of time.

"Great!"

Chang Haonan flicked the report in his hand lightly:

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

"Yes, when Lao Cao found me this morning, the whole person was about to jump."

Ding Gaoheng put the report back on the table:

"This thing designed by you seems to be inconspicuous, but the significance to the country and the people is no less than those previous achievements, I think, there must be a loud name."

"In the mythological story, Dayu has four innate treasures in his hands, I think, it is better to name one of them related to water control."

"Let's call it 'Nine Heavens Rest'!"
