Name: Super water-absorbent polymer combining polyacrylic acid and polyacrylamide
Appearance: white granular
PH value: Neutral
A brown glass bottle is placed on the table, with a label written in small letters on the bottle.
Li Aiguo excitedly picked up the bottle, poured the white granular substance into the beaker, and then picked up a measuring cup of water and poured it in.
As the water is poured in, the white granular material seems to melt into colloid.
The onlookers held their breath as they waited for the subsequent chemical reaction.
They mobilized the entire factory to build this thing, which took nearly two months and cost 53,827 yuan and 52 cents.
It must be a great thing.
Then
There is no more.
The military representative seemed to nod with satisfaction, and specifically instructed the chemical engineering room to produce another batch of polymers according to the same standards.
After this skill, the researchers were shocked.
"This thing doesn't look like a chemical weapon, does it?"
"Did we make a mistake?"
"No way, we spent so much effort and just got a bunch of gel?"
Zhu Yuanrong, the deputy team leader, couldn't help but chew his teeth.
He approached Li Aiguo and asked in a low voice: "Representative Li, are there any other special chemical preparations for this material?"
"Only water-absorbing properties."
Zhu Yuanrong: "."
Seeing the expressions of those researchers looking like old men on the subway, Li Aiguo did not explain much.
If these researchers knew that what he was going to make were diapers, they might be angry at themselves for wasting technology funds.
Seeing that something was wrong, Zhu Yuanrong took the initiative to find a step for himself.
"Ahem, this is a special material needed by the army. Everyone must abide by the confidentiality discipline. Don't pry around if you shouldn't pry."
The statement of "special materials" successfully solved all the problems, and the researchers all expressed "that's it" expressions.
After the project was a complete success, the project was classified as confidential because it involved special materials.
Neither technology nor raw material formulas shall be leaked.
In particular, the production process of "special materials" is also confidential.
The production plan is replaced by a confidential code name. The production workers are advanced elements with a high awareness of confidentiality, and the workshop is not open to the public.
Even if diapers are promoted in the future, it is impossible for anyone to get the production details.
Li Aiguo did not treat the researchers and production workers badly and took credit for them in the name of Unit 4373.
At a celebration party held at the Beijing Chemical Plant, the researchers and production workers who participated in the research won third-class collective merit, and each received an enamel jar and a blanket.
Both researchers and production workers said from the bottom of their hearts: "This military representative is pretty good."
Li Aiguo was puzzled that Wang Qingqing, the leader of the project team, did not attend the celebration party.
Zhu Yuanrong and Wang Qingqing were comrades in the trenches. Although they had different ideas in the past, their relationship was a bit estranged.
After this project, the relationship between the two quickly became closer.
Zhu Yuanrong gave an explanation to Wang Qingqian: "The old director has been busy in his laboratory recently. It is said that he has found a new way to synthesize ammonia."
After finishing speaking, Zhu Yuanrong was still a little confused and added: "We have also studied ammonia synthesis technology before, and we only gave up when we encountered extremely big difficulties. How did the old director find a new way so quickly?"
Hearing this, Li Aiguo picked up his wine glass and drank it in one gulp.
He felt that today's Erguotou was particularly fragrant.
——
Three days later, large batches of a highly water-absorbent polymer material combining polyacrylic acid and polyacrylamide as the absorbent core layer were produced.
Li Aiguo returned home on his bicycle. As soon as he entered the door, he asked Chen Xueru to quickly sew a bag with old cloth.
"What are you doing?" Chen Xueru was surprised.
In these days, rags are also precious and cannot be wasted casually.
"I made a changing pad for Xiao Hongsheng."
Li Aiguo took out the absorbent core layer from the canvas bag.
Chen Xueru touched the soft absorbent core layer.
Although I don’t know if this thing is more absorbent than a diaper, but I am sure it is very comfortable on the buttocks.
Besides, all he needed was two pieces of cloth as big as his palm. Chen Xueru didn't hesitate. She sat in front of the sewing machine and kicked her long legs fiercely.
The cloth bag was made, and Chen Xueru also sewed two buttons on it.
Li Aiguo wrapped the non-woven fabric he made a while ago on the absorbent core layer, then put it into a bag and buttoned it.
He placed the diapers on the table and looked around. Although they were a bit rough compared to the industrially produced diapers in his previous life, they looked similar.
"Let's put this thing on the child tonight."
After eating, seeing Chen Xueru trying to coax Xiao Hongsheng to sleep, Li Aiguo handed over the diaper.
Chen Xueru patted Xiao Hongsheng and whispered: "Brother Patriot, can you do it? This is only one night."
"Don't worry, if it leaks onto the bed, I'll wash the sheets for you."
"How can a man wash the sheets?" Chen Xueru couldn't resist Li Aiguo in the end, and wrapped the diaper around Xiao Hongsheng's butt half-heartedly.
Don't tell me, Li Aiguo designed it according to Xiao Hongsheng's size. After buttoning it up, it fit just right.
It was the first time for Xiao Hongsheng to wear a diaper. He looked down at the weird diaper and made a babbling sound, as if in protest.
What about diapers? What about diapers?
"You brat, this is your diaper!" Li Aiguo slapped the little buttocks.
There is no other reason, just because QQ bounces and feels so good.
Xiao Hongsheng: "."
The night is getting darker.
After Chen Xueru and Li Aiguo completed a round of driving training, they dragged their tired bodies and wanted to go to the next room to check on Xiao Hongsheng's diaper condition.
"Don't worry, there will definitely be no leakage." Li Aiguo put his arms around her, and Chen Xueru snorted and fell into the warm embrace.
It's very hard for a mother to pull a child.
In the past, Chen Xueru had to get up and check on Xiao Hongsheng four or five times every night, which especially affected her sleep.
Last night, under Li Aiguo's "coercion," she slept until dawn.
When I opened my eyes, I saw dawn.
Chen Xueru was still a little confused. When she heard Xiao Hongsheng's babbling shouts next door, she suddenly woke up, put on her clothes and ran to the next room.
When a child cries, he either wets the bed or is hungry.
Chen Xueru picked up Xiao Hongsheng and reached out to touch the sheets.
The sheets were clean.
Taking a closer look, the diaper ball had swelled several times in size.
What surprised Chen Xueru was that after taking off the diaper, there was no sign of moisture on Xiao Hongsheng's butt, as if she had not wet the bed at all.
"This, this is amazing."
Chen Xueru stared at the diaper with eyes shining brightly.
She carried Xiao Hongsheng to the main room and asked hurriedly: "Brother Patriot, did you make this diaper?"
"Yeah."
“Is it expensive?”
Li Aiguo was arranging his clothes and was stunned when he heard this.
Currently, there are no plans to sell diapers domestically, and the price has not yet been calculated.
After a simple calculation, I came up with a figure: "The cost is about eighty cents."
Among the costs of diapers in later generations, 30%-50% are material costs, labor costs account for 20%-30%, R&D and design costs are 10%-15%, and sales channel costs account for 10%-20%.
The total cost is about sixty cents a piece.
In these days and months, labor costs are very low.
Self-research and development is considered a one-time investment and does not need to be included in the calculation, and the cost of sales channels is completely eliminated.
However, because there was no large-scale industrial production, the cost of materials was several times that of later generations, so the price was as high as 80 cents.
If mass-produced, the total cost is estimated to be reduced to 50 cents a piece.
When she heard "eighty cents", Chen Xueru seemed hesitant, but she looked at Xiao Hongsheng, and finally bit her lip and said: "Brother Patriot, can you make another batch? I can use my own salary to pay for this." money.”
Chen Xueru's "luxury" exceeded Li Aiguo's expectations.
You must know that Chen Xueru is now a street office employee, enjoying the treatment of a thirteenth-level clerk, and her monthly salary is only 32 yuan and 50 cents.
She was unwilling to eat white flour steamed buns, but she was even willing to spend 80 cents on diapers.
Sure enough, children’s money is the best to earn!
Of course Li Aiguo would not accept this money from Chen Xueru.
"Don't worry, I have a way to get a batch of free diapers."
Chen Xueru's first thought was not to be excited, but to ask: "You won't make a mistake, will you?"
When she received Li Aiguo's affirmative reply, Chen Xueru breathed a sigh of relief.
She rubbed Xiao Hongsheng's hair and said with a smile: "Our Hongsheng's little butt will never get a red rash again."
Li Aiguo also changed his mind at this moment. Following the example of Chen Xueru, perhaps he should first produce a batch of diapers and test the water through the internal store of the Qianmen Locomotive Depot.
But the road must be walked step by step, and the meal must be eaten one bite at a time, so don't be in a hurry.
After breakfast, Li Aiguo sent Xiao Hongsheng to the nursery, and Chen Xueru helped sew a batch of diaper bags at home.
After Li Aiguo "assembled" the diapers, he counted the number.
The first batch contained 350 diapers, of which 300 were packed in boxes and the remaining 50 were left at home.
Since diapers are produced, they should be inspected.
Li Aiguo rode his bicycle and wandered to the Shijingshan weather station.
He first gave Wu Jingzhong the fried cakes he bought on the way.
This old man has almost been "cleaned", and maybe he will be able to leave the courtyard and work at the weather station soon.
Later, Li Aiguo brought the cardboard box to the supplies department and knocked on Director Shu's office.
Director Shu was writing an application report when he saw Li Aiguo coming in wearing a lieutenant colonel uniform and seemed to understand something.
She put down the pen and said with a smile: "Director Li, have diapers been developed?" Li Aiguo placed the cardboard box on the table, took out a document from the canvas bag and handed it over: "Report to Director Shu, in the capital With the strong cooperation of the chemical industry, we have produced the first batch of diapers, with a total quantity of 351 diapers
However, fifty-one of them have been inspected and found to be of unqualified quality. In the spirit of not wasting money, I personally am willing to invest in the purchase. ”
Director Shu was experienced and immediately understood what was going on.
But she didn't care at all.
After all, diapers are not a military product, and sometimes the masters in the supply department will buy substandard products at cheap prices.
This does not cause waste and is convenient for the masters.
In particular, Director Shu knew very well that Li Aiguo was responsible for the diaper project alone. Even if he concealed the substandard products, others would not know about it.
Thinking of this, Director Shu looked at Li Aiguo with more respect.
It seems that the farmer can accept this young man as his apprentice, not just because of his merits.
"Director Li, there is no need for personal investment."
"Director, let's follow the rules."
Check out the 16-9 book bar and see the correct version!
Seeing Li Aiguo's insistence, Director Shu had no choice but to agree.
After counting the diapers, she signed the list, and then the batch of diapers was registered in the Materials Department as special equipment.
Coincidentally, before Li Aiguo left the supply office, Lao Mao opened the door and walked in.
He brought three team members to collect the equipment.
Seeing the tired faces of the four people who had not slept for seven or eight days, and smelling the stench of sweat on their bodies, Li Aiguo understood that they were performing a surveillance mission.
Director Shu saw that Deputy Director Li Aiguo was watering flowers leisurely and handed him the order.
"Director Li, check it out. If there are no problems, take them to the warehouse to get the equipment."
Li Aiguo was worried that he couldn't ask about the content of the mission because he didn't participate in the mission. He was dozing off and bumped into the pillow sender.
Received the equipment application form: bottled water (boiling water in beer bottles and cans), telescopic bird watching device.
Li Aiguo was very sure that Laomao and the others were performing a surveillance mission, and this mission was quite important.
"Team Leader Laomao, what's going on with these four camouflage suits?" Li Aiguo looked at them for a while and pointed at one of them.
As the deputy director of the Materials Division, he has the authority to review the equipment needed for the operation.
It is only natural for Lao Mao to introduce some details of the operation at this time.
It turns out that the surveillance mission carried out by Lao Mao and the others this time is very difficult and demanding. They need to keep the target in sight 24 hours a day.
The target under surveillance lives on the fifth floor of Tongzi Building.
Because there was no building on the opposite side, Lao Mao had to lead two team members to climb a big tree and stare at each other with binoculars on the branches.
"These camouflage uniforms can prevent team members from being discovered in big trees." Lao Mao explained: "Because every time they go up or down the tree, they may be discovered by the target, so we adopted a dead-eye approach and rotated every three days. A group of players.”
Li Aiguo couldn't help but take a breath of cold air after squatting on the big tree for three days.
"Then how to solve your life problems."
"In order to avoid excretion, you can only eat a small amount or not eat during these three days. However, you must replenish water. If you drink water, bottled water
This will ensure that you will not go to the tub for three days, and you will have to urinate on a tree. ”
After Li Aiguo figured out the details of the operation, his eyes lit up and he patted Old Mao on the shoulder: "Team Leader Cat, I recently tinkered with a new gadget called diapers. Come and find out about it!"
——
In this way, Laomao's action team became the first team to be equipped with new equipment-diapers.
Three days later, the team members sent back feedback that diapers were particularly convenient for surveillance work. Laomao also listed the use of diapers as a necessary equipment for surveillance work in the action report.
The farmer didn't pay much attention to diapers at first. After listening to the old cat's opinion, the farmer officially included diapers in the ranks of special warfare equipment.
Half a month later, a special operations unit in Beijing conducted extreme training in the wild.
In order to maximize the capabilities of the special operations team members, diapers are also included in the backpacks of the special operations team members as special operations equipment.
Li Aiguo also specially wrote an instruction manual for the special forces: "In addition to regular uses, diapers can also be used as shoe insoles."
Because of the blessing of diapers, the training performance of the special teams team has improved a lot, and the rate of foot injuries has been greatly reduced.
After the training, diapers officially entered the military region's special equipment procurement sequence.
The Jingcheng Chemical Factory received a large order from the military region, and the confidential production line was started again to expedite the production of a large number of diapers.
Of course, these are all things for later.
After the success of diapers as a military product within the weather station, the port city also completed the patent application process.
Li Aiguo then put the diapers into the international mail package and sent them to Andrei in Moscow via international train.
Andre sat on the big leather sofa, looking at the mail package in front of him, a little confused.
"Driver Li told me on the phone that he could solve the problem of astronauts going to the toilet. Why did he only send a piece of cotton cloth?"
"Master, there is another letter here." The butler held the letter in his hands and handed it to Andre.
Andre put out his cigar and picked up the letter.
"Dear Comrade Andre, this thing is called a diaper and it has the characteristics"
After looking at it for more than ten minutes, Andre put down the letter and picked up the piece of cotton with a suspicious look on his face.
He could never understand that a piece of cotton could absorb more than ten times the volume of water or urine.
But Andre didn't hesitate for long.
After all, whether the problem of astronauts going to the toilet can be solved should be determined by the Moscow Academy of Sciences.
Andre was already keenly aware that diapers could be used not only by astronauts, but also by children.
This is a huge business opportunity.
"Let the Moscow Academy of Sciences help us test whether this thing works or not."
"But if the diapers are handed in through other people's hands, I'm afraid those guys will keep it for themselves."
"For tens of millions of rubles, I have no choice but to go to the Moscow Academy of Sciences myself."
"Vishnyak, do you think I am too tired?"
Andre asked the butler with a smile while asking him to contact the Ministry of Aviation Industry.
The housekeeper whispered: "Master, you are different from those dandy boys. I have made it clear in family meetings several times that you will inherit the glory of the family in the future."
"Family glory. Hahaha. The driver once said that it is better to save money and food than guns. As a money saver, how can I compare to my good brother in the Northern Fleet."
Andre's words sounded a bit joking, but his tone was serious and full of reluctance.
The housekeeper was aware of the internal fighting within the family and did not dare to say anything, so he could only pretend not to hear.
He shook the phone, waited for the call to connect, and handed the phone to Andre.
The moment Andre got the phone, the unwillingness disappeared without a trace, and a bright smile appeared on his face.
"Uncle Yaroslav, I'm little Andrei. How did the batch of caviar you received last time taste? It was top quality from Finland."
"What? Capitalist things are inappropriate? That will not be an example."
"In two days, there will be a batch of instant noodles shipped from the East. They are beef-flavored. I will deliver them to you."
"Yes, yes, it's the Red Star brand."
"Uncle, little Andre needs your help with something. Here's the thing"
Andre talked on the phone for ten minutes before hanging up.
"Prepare the car, let's go to the Ministry of Aviation Industry first."
He stood up, changed out of his fur coat, and put on the long double-breasted woolen coat.
This coat not only has exquisite epaulettes and stiff fabric, but also comes with a distinguished Astrakhan fur collar. More importantly, there is a row of medals pinned to the front of the coat.
——
Because most of the diapers produced were purchased by major military regions, especially the frontier corps.
Therefore, Li Aiguo's plan to sell diapers in the capital was greatly delayed.
But he was not in a hurry.
As the production volume of Jingcheng Chemical increases, diapers will one day be placed on the counters of supply and marketing cooperatives.
Li Aiguo is living a very happy life these days, driving a big train every day and continuing to write in his spare time.
With those defective diapers, Miss Chen no longer has to wash diapers, and her life is quite happy.
But soon the residents in the compound felt something was wrong.
Because in the past, Miss Chen had to work by the sink with a basin of diapers almost every day.
He has been missing for a while.
Liu Lan whispered about this while washing the diaper.
"Chen Xueru must be lazy." Jia Zhang sat next to her and said holding her mouth.
She looked at Qin Huairu who was busy and said, "Although our Jia family's daughter-in-law has no formal job, no education, and is not smart, she still has advantages."
In these days, it is a huge insult for a woman to be considered lazy.
Jia Zhang rarely praised Qin Huairu, and He Yuyu, who was doing homework next to him, stopped at that time.
"Ms. Jia Zhang, what are you talking about! Sister-in-law Xueru is a well-known diligent wife in our compound. The reason why she didn't wash the diapers is because Xiao Hongsheng doesn't need diapers now."
As soon as these words came out, Jia Zhang burst into laughter.
"Are you kidding me? In all my life, my old lady has never seen a baby under one year old that didn't wet the bed. Rainwater, you used to be a good girl, but how did you get led astray by Li Aiguo?"
He Yuyu was angry: "I'm telling the truth! Brother Patriot made those diapers himself. They only fit under the child's buttocks, so they don't have to change diapers all day long."
"And there are diapers? Rainwater, you can lie to my old lady, but don't lie to yourself." Mrs. Jia Zhang still didn't believe it.
At this time, Liu Lan made a sound, raised her head suddenly and said, "Don't tell me, I seem to have seen it before. It was wrapped in a cloth bag and filled with something very soft, like cotton.
Yesterday Chen Xueru was throwing away garbage with me, and I saw it in her basket. ”
"I've seen it too. I thought it was good cotton, but it was just wet. Who knew that when I took it back to dry, it didn't dry even after several days."
The third uncle took out a diaper from the house and handed it to the residents.
The residents were all amazed after seeing it.
"This thing does look like cotton, but it probably isn't."
"How comfortable this pad is under your buttocks. No wonder Xiao Hongsheng's buttocks haven't had a red rash recently."
Liu Lan was also moved when she heard this.
These days, due to lack of vitamins, it is common for children to have rotten buttocks.
Although Liu Lan changed little Xuhua's five diapers every day, little Xuhua's buttocks were still red.
