The next day, the sun rose as usual.
The adults got up early and started their busy day.
Some carried brooms to clean the yard, while others carried buckets to fetch water from public faucets.
The women lit the stove in the kitchen, and smoke rose from the chimney. After a while, the air was filled with the fragrance of rice porridge and the earthy taste of steamed buns.
The courtyard gradually wakes up in the early morning, like a picture full of age and life, slowly unfolding in front of Li Aiguo.
Li Aiguo had a bad appetite in the morning.
After simply eating five white-flour steamed buns and a bowl of stick noodle porridge, we were ready to head to the locomotive depot.
After playing Tie Tie with Miss Chen, I picked up my canvas bag and pushed my bicycle out of the house.
As soon as he walked to the door, he saw Nan Yi sweeping the floor with a big broom. Li Aiguo shouted to Nan Yi.
“Patriotic brothers, you have to go to work so early.” Nan Yi put down his broom and ran over.
"Yes, our locomotive depot has developed a new mouse-catching device. I have to keep an eye on it."
As he spoke, Li Aiguo took out two mouse-sticking boards from his pocket and handed them over.
"This is an experimental product made by the studio, you can use it."
"What is this thing for?"
Nan Yi took the mouse board, reaching out to lift the oil paper covering the sticky mouse board.
Li Aiguo stopped him and explained: "There is glue on the board, which can stick to mice. If you put some nests on it, the effect will be better."
I heard it is for catching mice. Something, Nan Yi suddenly became interested.
He came from a poor background and was trying to get ahead by taking advantage of the opportunity of getting rid of his four legs.
Otherwise, I wouldn’t have thought about catching sparrows in the first place.
“Patriotic brother, thank you so much.”
Nan Yi seemed to remember something.
I said "just wait", and when I came out, I had a newspaper bag in my hand.
“These are the ingredients I just prepared. The stews and stir-fries are very fragrant.”
The ingredients of Nan Yi Diao are considered to be the best in the compound, and they are no better than the Shisan Xiang of later generations. Not bad, add a little when cooking, the food will be fragrant.
Li Aiguo did not refuse, put the paper package into a canvas bag, got on his bicycle and left.
When we arrived at the maintenance workshop at the Qianmen Locomotive Depot, the workshop was already bustling with people.
The faces of the workers were full of fatigue, and dark circles were deeply imprinted around their eye sockets, which was the mark of exhaustion and sleepiness.
My eyes were bloodshot, but I still stared firmly at the unfinished work in my hands.
Hey guys, this is going to be a spin.
Li Aiguo came to the director's office.
Director Zhang is leading a group of clerks to put the produced sticky mouse boards in the box.
"Lao Zhang, we can't go on like this, the workers' bodies won't be able to bear it."
Director Zhang raised his head, yawned and said: "Driver Li, don't worry, the first batch of production tasks It will be completed soon.”
“A total of two thousand sheets, all completed?” Li Aiguo’s eyes widened.
Director Zhang raised his head proudly and said: "Yes, last night except for a few technicians who ensured the maintenance of the locomotive, all the workers were dragged to production. Even the leaders in the workshop On the front line."
Li Aiguo: "."
He really underestimated the importance of honor to Director Zhang and these workers.
Ten o'clock in the morning.
After the first batch of two thousand sticky mouse boards was produced, Li Aiguo and Director Zhang brought the sticky mouse boards to the logistics office.
A crisp sound rang out from the loudspeaker in the locomotive depot at the front door.
"Comrade workers, please pay attention. Comrade workers, please pay attention. The good news is that in order to actively respond to the call to get rid of the four-legged rats, driver Li from our Qianmen locomotive depot and the maintenance workshop jointly developed and produced a batch of sticky mouse boards that can be used to catch mice. Rat.
Comrade workers, please come to the logistics office to get it, the quantity is limited, first come, first served.”
Boom!
Hearing the sound of the announcement, the entire locomotive depot immediately became excited.
The workers in the locomotive depot have been suffering from rats for a long time. The price of rat traps in Beijing has remained high. With the sticky rat board, the task of removing rat traps is easy.
In less than a moment, a long queue formed at the door of the Logistics Department.
The two thousand sticky mouse boards were quickly distributed.
The mice of this era have not seen high technology.
The effect of sticky mouse boards is better than mouse traps. In less than one morning, the locomotive depot harvested more than 300 mouse tails.
“If there were 20,000 rat-glued boards, our front-door locomotive depot would be at the forefront of all locomotive depots except for the four.”
Duan Chang Xing and the leaders of the Yizhengzi Locomotive Department counted the rat tails, and decided to expand the production scale and produce another 10,000 sticky rat boards.
However, the production plan soon ran into trouble.
In the maintenance workshop, the quantity of phenol resin adhesive is not enough to produce so many sticky boards.
Duanchang Xing coordinated the chemical industry department in the name of the Qianmen Locomotive Depot, hoping to urgently purchase a batch of phenol resin adhesives.
As a result, I was told that this year's production plan was already fully booked, and that we would not be able to provide phenol resin adhesive to the locomotive depot in the short term.
The chemical industry sector has a special status these days, and the name of Big Brother Railway is not easy to use.
Director Zhang of the Maintenance Workshop suggested: "Commander Duan, if we use all the phenol resin adhesive in stock, we may be able to meet production needs."
"In that case, yes Will it delay the preparation of the carriage?" asked Duan Chang Xing.
Director Zhang nodded.
"No, although it is important to remove the four prongs, it cannot delay our normal work. We cannot put the cart before the horse." Duan Chang Xing immediately rejected Director Zhang's proposal.
A deputy section chief put forward a new idea: "Is there any material that can replace phenol resin adhesive?"
Everyone's eyes turned to Li Aiguo.
The pressure came to Li Aiguo again.
In fact, Li Aiguo has been thinking about this issue.
Mouse stickers are disposable consumables and consume a lot of money.
In later generations, phenol resin adhesives were not worth much, but in this era they were valuable chemical products. This is destined to make it impossible for large-scale promotion of mouse stickers produced using phenol resin adhesive as raw material.
Tools like mouse pads will become meaningless if they cannot be popularized due to cost and technical issues.
The best way is to find a material that can replace phenol resin adhesive as glue.
It’s just that the sticky mouse board has very high requirements on the adhesive strength of the glue, and ordinary materials cannot meet the needs.
Li Aiguo also experimented with mature tung oil.
Although this thing is very sticky, the mouse can still escape after paying some fur.
Suddenly.
A bright light flashed in Li Aiguo's mind.
The ink used by the third uncle to stick the mice seems to be quite sticky.
If you mix ink with cooked tung oil and vegetable oil in proportion, the viscosity may be able to meet your needs.
Li Aiguo remembers that someone in later generations did this, and the effect seemed to be pretty good.
"Chief Duan, is there any ink in our maintenance depot?"
"Ink? There should be a lot in the education room. Do you want to use ink to replace the phenol resin adhesive?" Xing Duan Chang said in surprise.
“Just ink is definitely not enough, you also need cooked tung oil and vegetable oil”
Li Aiguo expressed his thoughts.
Xing Duanchang’s eyes lit up.
Although it still needs experiments to determine whether these materials are suitable for use as sticky mouse boards.
But there is no shortage of ink and cooked tung oil in China.
"Let's do this, I will approve a hundred yuan of scientific research funds for you, and you can take a few days off from the Railway Research Institute to study this matter specifically."
Xing Duanchang was at this time I also realized that if the rat stickers could be widely promoted, the domestic situation of getting rid of the four-legged crotch would be greatly improved.
Hearing this, Director Zhang scratched his head depressedly.
How did Li Aiguo get the scientific research funds without even opening his mouth?
While he was thinking, Li Aiguo patted him on the shoulder: "Lao Zhang, let's go and get the money."
"Ah? I have a share too!"
Director Zhang saw Li Aiguo nodding, and the old technician-turned-workshop director almost jumped up.
It’s not that he wants these scientific research funds.
But as a technician, I have worked hard all my life and have not received a single scientific research fund, which is a bit embarrassing.
The two came to the logistics office. After Li Aiguo handed over the note, he took one hundred yuan from Section Chief Zhang.
Director Zhang saw Section Chief Zhang filing the note and made a request.
"Old Zhang, can you write me a note?"
Section Chief Zhang was confused by Director Zhang's request.
He kindly told Director Zhang that the note he wrote as the section chief had no effect at all.
Director Zhang still insisted on his idea.
“Don’t worry, just write the note.”
There was no other way, Section Chief Zhang could only make a copy of Duan Chang Xing's note to Director Zhang, and marked it as a "sample" on it.
Director Zhang got the note and ran all the way.
He ran to the office of Chen Gong in the maintenance workshop and slapped the note on the table.
"Old Chen, I am also a person who works on big projects! A big project worth a hundred yuan."
Li Aiguo looked at his proud look and shook his head helplessly. shook his head.
It seems that even though Director Zhang became the workshop director, he still positioned himself as a technician in his mind.
After Director Zhang became a great technician with a hundred-dollar project, he became very motivated.
It only took half a day to collect seven or eight kinds of materials including cooked tung oil, ink, and sanitary oil.
Li Aiguo led a few people to work in the workshop.
Experimental mixing of materials is a troublesome matter.
In one morning, I experimented with more than fifty mixing ratios, but the viscosity of the finished product did not meet the requirements.
But Li Aiguo is not in a hurry. After all, he has the eye of the sky and knows that this method is feasible.
All it takes is a little time.
While Li Aiguo was busy preparing new glue.
Nanyi Family in the Siheyuan.
Nan Yi squatted in front of the sticky mouse board, tilted his head and fell into silence.
In order to catch mice, Nan Yi put a piece of meat as bait.
The sticky mouse board has been left in the house all morning, but not a single mouse has been caught.
On the contrary, I caught seven or eight flies.
“This thing was developed by Brother Patriot, so it should be very easy to use.”
Seeing Nan Yi's confusion, Liang Ladi reminded her with a smile: "Is there a possibility that there are no mice in our house anymore?"
As soon as these words came out, Nan Yi realized that he was confused. .
A while ago, Nan Yi used the scraps he had saved at home for half a year to buy two mouse traps from Wang Dakui, and caught seven or eight mice in total.
In addition, other houses in the compound also installed mouse traps.
There are mouse traps next to the pool, in the corners, and under the big trees. Rats will have their legs clipped even in the walkways, let alone stealing food.
In this case, we haven’t seen a mouse in the compound for a while.
"Hate, I originally thought I could get ahead by sticking a mouse board, but now it seems there is no hope."
Liang Ladi stretched out her finger and tapped Nan Yi's forehead. Point: "Are you stupid? This thing can not only catch mice, but also flies. Fifty flies are equal to one mouse. As long as you catch more flies, you can still compete for the lead."
