Last year, Li Donglai was just an expert in the pharmaceutical industry, but with the popularity of electric bicycles, everyone discovered that Li Donglai also had profound knowledge in the machinery industry.
There are even rumors that Li Donglai is also proficient in astronomy and geography. Director Zhang is also interested in this, so he wants to take this opportunity to test Li Donglai.
Of course Li Donglai agreed: "Guidelines don't count. Our laboratory is currently studying transistor radios. Although there are big differences between transistor radios and tube radios, their main principles are still the same. This time we are working with each other.
comminicate"
Saying this, several people entered the production workshop together.
The production workshop of the radio factory was much cleaner than ordinary production workshops. There was no dust on the ground and the tables were wiped clean. However, Li Donglai still frowned.
But after all, this is someone else's territory, and it's hard for Li Donglai to say anything.
Seeing several people walking in, Zhang Xiaolan raised her hand and said: "Director, I have a problem here. All the circuit boards produced in our workshop today are not up to standard."
Zhang Xiaolan is responsible for testing. If the quality of the circuit board is not up to standard, there will be no way to assemble it on the radio.
Especially after the circuit board is produced, it is very difficult to repair it again. Sometimes it is even harder to find the faulty place on the circuit board.
Director Zhang looked at the large pile of circuit boards and saw that there were dozens of them. His face was as black as ink.
In this era, the production technology of circuit boards was not mature, and the production costs were extremely high. The production cost of a circuit board was as high as 20 yuan.
All these circuit boards are broken, and the radio manufacturer will have to pay at least several hundred dollars.
Director Zhang looked at Zhang Xiaolan and said: "Comrade Zhang Xiaolan, where does the problem lie? Have you found out clearly?"
Zhang Xiaolan is the leader of the quality inspection team. He is also responsible for analyzing problems in production to ensure that production can proceed smoothly.
Hearing Factory Director Zhang's question, Zhang Xiaolan sighed and said: "Director Zhang, this is the main reason why we invited you here. In fact, after discovering the first unqualified circuit board, I immediately organized
The technicians inspected the entire production process, but we technicians did not find any problems during the production process.
The workers in the workshop are all skilled workers, and their skills and operations all comply with the regulations of our factory. "
Hearing this, Director Zhang frowned.
As the designer of radios, Director Zhang set up a complete set of production processes in order to enable factory workers to successfully produce qualified radios.
As long as the workers follow the production process, generally speaking, there will be no major problems.
At this time, Director Zhang saw Li Donglai picking up a circuit board and asked curiously: "Director Li, did you find something?"
Li Donglai smiled and shook his head and said, "You can't tell anything wrong with a circuit board just by looking at it with your eyes."
This remark caused a burst of laughter.
The workers watching nearby had long been curious about Li Donglai. He was able to walk into the workshop side by side with normal people, indicating that he must also be a factory leader.
These workers do not have any good impressions of ordinary factory leaders.
“I don’t know where this guy came from, but he came to our place and pretended to be a technician.”
"Don't he know? Circuit boards are high-tech, and even the professors in the university can't just touch them if they want."
"I see, this guy is just a loser."
Hearing the workers' discussions, Director Zhang's face suddenly darkened.
He turned his head and said loudly: "Shut up, all of you. This leader is Director Li of our Jingcheng Steel Rolling Mill Laboratory. The electric bicycles that are now popular all over Beijing are the work of Director Li."
After hearing Factory Director Zhang's words, the workers all understood Li Donglai's identity, but they still didn't take it seriously.
“Electric bicycles don’t have much technical content, and there’s no way they can compare with our radios.”
"Yes, yes, an electric bicycle is actually a bicycle with a battery added to it. Even children can build it, so what's so great about it?"
"I think our factory director thinks too highly of Director Li."
....
Factory Director Zhang was also confused by these workers.
He looked at Zhang Xiaolan coldly and said, "Team Leader Zhang, don't your workers know some rules?"
Although Team Leader Zhang said in an apologetic tone: "Director, don't you know these workers in our factory? Everyone always looks down on those who are incompetent, especially those who are incompetent. Factory leaders, I can
what else can we do?"
In fact, in Zhang Xiaolan's view, Li Donglai's behavior of picking up the circuit board just now was already questioning his professionalism.
As the leader of the quality inspection team, he is proficient in the entire production process of circuit boards and can now find no faults. It is really outrageous that Li Donglai, an outsider, is here to point fingers.
Factory Director Zhang was also very angry with these workers.
But he had no choice. After all, for the factory, the workers were the owners of the factory. As the factory director, he had no choice but to order the workers to apologize to Li Donglai.
Factory Director Zhang looked at Li Donglai and said, "Director Li, I'm really sorry for what happened today. These workers don't understand anything."
Li Donglai didn't pay attention, but started walking around the workshop with his hands behind his back.
Seeing this situation, Director Zhang followed him and asked in surprise: "Director Li, did you discover something?"
Li Donglai said with a smile: "Not yet, but I think it's a bit strange."
It hurt again. When the onlookers heard Li Donglai's words, they laughed out loud again: "Are you kidding? The production process in our workshop has been carefully studied. That leader, I think he is just pretending to understand."
This chapter is not over, please click on the next page to continue reading! "Such a person simply has no self-awareness."
....
The workers were discussing Li Donglai when they suddenly stopped.
He turned to look at Factory Manager Zhang and said, "Director Zhang, isn't there a place to eliminate static electricity in your workshop?"
Hearing Li Donglai's words, Director Zhang was immediately confused: "What is the elimination of static electricity?"
Seeing Director Zhang like this, Li Donglai sighed and said: "Director Zhang, I think you should also know that if these electron tubes are damaged by static electricity during the production process, the internal structure of the tubes will change.
.Ultimately, the circuit board cannot function properly."
Factory Director Zhang himself has a professional background and is a technician. His expression suddenly changed when he heard this.
He knows very well the harm of static electricity to electronic tubes.
Zhang Xiaolan said a little disapprovingly: "Director Li, is he as evil as you said? Isn't it the kind of static electricity that crackles when we take off our sweaters? In the process of producing vacuum tubes and circuit boards, our hands
There is never any static electricity on it.”
Looking at Zhang Xiaolan who was a bit convinced, Li Donglai felt that the level of scientific knowledge of these workers should be improved a little bit.
"Comrade, I don't know if you understand the principle of static electricity. Static electricity is a kind of charge in a static state or a non-flowing charge. Static electricity is formed when charges accumulate on an object or surface.
Electric charge is divided into two types: positive charge and negative charge, which means that the electrostatic phenomenon is also divided into two types, namely positive static electricity and negative static electricity.
Static electricity is formed by the redistribution of charges caused by friction, or by the redistribution of charges caused by the mutual attraction of charges.
That is to say, as long as there is friction, there will be static electricity. Even if the static electricity is so small that it cannot cause crackling, it can penetrate the inside of the electron tube."
Hearing this, Zhang Xiaolan was confused: "Director Li, if the static electricity you mentioned is so powerful, why haven't we encountered it before?"
The workers who were watching also nodded and said.
"Yes, since we are all charged with electricity, why haven't the tubes we produced broken before?"
"I see, this person is just talking nonsense."
"He used a lot of nouns in his verbose words, trying to fool us."
Director Zhang seemed to have remembered something at this time and shouted at them: "Shut up, everyone."
The workers were shocked. Director Zhang had a high prestige in the factory after all. The workers all lowered their heads and remained silent.
Director Zhang turned to look at Li Donglai and said: "Director Li, I hope you can explain clearly about static electricity. This may be related to the yield rate of our workshop."
Li Donglai said with a smile: "Comrades' question is very good. Static electricity can be generated and eliminated. Especially when the air is humid, the amount of static electricity generated will be less than before.
Therefore, in the spring, summer and autumn seasons, there is no problem with the yield rate of your workshop.
But now that the weather is dry in winter, the dangers of static electricity have become apparent."
Hearing Li Donglai's words, Zhang Xiaolan nodded and said: "That's right, there were indeed defective products in our workshop in the past. At that time, I thought it was because the workers did not operate according to the rules and regulations. Now I think it was also caused by static electricity.
of."
Director Zhang looked at Li Donglai and asked: "Director Li, is there no way to avoid the static electricity you are talking about? If that is the case, we will not be able to produce electronic tubes in winter."
Li Donglai said with a smile: "Of course not. In fact, there are many ways to avoid static electricity. The simplest way is to set up a static electricity elimination tool in front of each worker's workstation in the workshop. Before workers start working, as long as their hands are on
Just touching the tool will eliminate most of the static electricity."
"But according to what you said, there should be static electricity in the air. What should we do with that static electricity?" Director Zhang asked.
Li Donglai said with a smile: "Static electricity in the air is more troublesome. This requires the transformation of the entire workshop, and there are also certain requirements for workers' clothing. It is almost impossible to transform the entire workshop now, and the transformation of the workshop requires
I don’t think your factory can afford the cost now.”
Li Donglai was not trying to scare Factory Director Zhang. In later generations, static-free workshops were very common and the cost was not particularly high. Almost every factory had such a workshop.
But in this day and age, it is really difficult to build a static-free workshop.
Li Donglai continued: "If you want to avoid static electricity, workers cannot wear furry clothes. The best way is to wear special experimental robes for the laboratory. Because the surface of the experimental roe deer is relatively smooth, it will hardly generate static electricity. In addition, the workers
Their hair should also be wrapped in a cloth.
Workers' shoes should also be wrapped in plastic bags to avoid friction with the ground and causing static electricity.
As long as these few things can be done, even if there is no way to avoid most static electricity, the yield rate can be greatly improved."
After listening to Li Donglai's words, Director Zhang quickly took out a pen and notebook and wrote down all Li Donglai's paintings in the notebook.
"Director Li, you are absolutely right. I will rearrange our workshop according to your ideas in a moment, and ask everyone to change their clothes according to your requirements."
The workers, who had been so aggressive before, now looked at Li Donglai in disbelief after hearing Factory Director Zhang's words.
It is really incredible that this young man can improve the yield rate in the workshop with just a few words.
Zhang Xiaolan thought about what happened just now. He walked up to Li Donglai and said awkwardly: "Director Li, I'm really sorry just now. I shouldn't doubt you."
This chapter is not over yet, please click on the next page to continue reading! Li Donglai laughed twice and said nothing more.
Director Zhang stared at him and said, "Zhang Xiaolan, before you get off work today, you write a letter of apology and hand it over to my office."
Director Zhang felt very ashamed.
Our own workers actually went out of their way to do things at work in front of others, but they ignored the past and took the initiative to help the workshop solve the static electricity problem.
After dealing with Zhang Xiaolan, Factory Director Zhang temporarily closed the workshop and waited for the workshop renovation to be completed before reopening production work.
Because he understands that there must be a lot of static electricity in a workshop that has not been renovated. In this case, if the production work continues, a large number of substandard products can only be produced.
Li Donglai also nodded in agreement with Factory Director Zhang's opinion. They chatted for a few words and then left the workshop.
Factory Director Zhang looked at Li Donglai and said gratefully: "Director Li, you have helped our workshop so much this time. I really don't know how to thank you."
Li Donglai chuckled, took out a list of materials from his pocket and handed it to Director Zhang: "It's a coincidence, Lao Zhang, I am worried about the materials above. I passed by your workshop and if there are these materials, they can be sold.
Give us the rolling mill."
Director Zhang took the list of materials and just glanced at it twice. His expression suddenly changed.
He looked at Li Donglai and laughed loudly: "Director Li. Our factory has all the things above. You haven't been eyeing our factory for a long time, right?"
Li Donglai smiled and said: "How can this be possible? Brother, do you think I am the kind of person who likes to collect wool? Besides, our steel rolling mill can directly exchange grain and pork for this batch of materials."
Hearing what Li Donglai said, Director Zhang nodded immediately.
In this era, materials are scarce, and sometimes you can't buy food even with money. The steel mill laboratory has a lot of money, and with the support of the department, there is no problem with food supply.
But the radio factory is different.
After reaching an agreement, Li Donglai did not stay longer at the radio factory. He returned to the steel rolling mill and contacted a batch of materials to be transported to the radio factory by truck.
The truck left the steel mill carrying the grain, and when it came back, it brought a lot of materials.
Li Donglai directed the workers to carry the materials into the laboratory.
He looked at the materials and said boldly: "From now on, our research work on transistor radios has officially begun."
