Chapter 364 The package ABS is available, but not all
At work on Monday, Gao Zhendong first called Factory 1274 and asked them to summarize the current research status of integrated circuit technology and send it to himself, while suspending The research work on integrated circuit technology will be arranged by yourself.
This shocked Factory 1274. What?
"General Engineer Gao, has this project been affected in any way? Why is it suspended?" General Engineer Lu asked worriedly.
Is it because my progress is too slow and people are dissatisfied?
For ordinary people, once the project is launched, it basically cannot affect their life or death, unless there is a clear problem with the project, but Gao Zhendong is different. He really has the ability to affect his life and death.
To take a step back, even if it does not affect life or death, it can definitely affect whether the specific executor should be replaced. For 1274, what is the difference between this and the death of the subject.
Gao Zhendong, an e-waste man in his previous life, had a famous saying - "It's more uncomfortable to watch netizens make money than to lose money yourself." Although Factory 1274 is not like this, it is absolutely unavoidable to lose money yourself.
Seeing that his lack of words frightened the other party, Gao Zhendong quickly explained with a smile: "No, no, I have recently thought of some new ways in this direction and achieved some new results. . So I want to see your current progress and direction, and see if you can combine them."
Mr. Lu was relieved. I told you earlier, it's scary, it's scary. Mr. Gao.
As soon as his worries were relieved, he immediately realized that this was a good thing. If Chief Engineer Gao said there was a new way, it must be a fairy fart, something extraordinary!
He immediately happily agreed and went back to arrange work.
After arranging this matter, Gao Zhendong started to fish, took out an interesting popular science book related to physics and started to revise it.
Mainly because I feel so strange when I see the two children of Wang Dezhu's family on weekends, and I always feel that I should do something for them. It doesn't take much time to revise a book.
As for why physics comes first, the main reason is that mathematics these days is really a bit wandering, and it is not possible to achieve immediate results without physics.
Moreover, some phenomena in physics are more intuitive and more interesting to children. Mathematics is a bit abstract. It is really abstract. I am not criticizing it.
Not to mention, the original author of this thing is really good at writing it. Even though Gao Zhendong understands most of the knowledge in it, but after changing it, he fell in love with it first, and it is quite special. Fascinated.
“Dingling bell”
Just when Gao Zhendong was enjoying fishing, the phone rang.
Gao Zhendong answered the phone, and on the other end was Mr. Xiang, the person Gao Zhendong had entrusted him with to make optical plastics and disposable tubes for ABS launch tubes.
But there was news, the time was not up, and Gao Zhendong couldn't rush others, so he kept waiting.
“Mr. Xiang, hello, hello, do you have any good news?”
Mr. Xiang smiled over there: “There is good news and there is bad news.”
"Let me tell you the good news first. I am happy first."
"We have already produced the material you want. After testing, the mechanical properties, corrosion resistance, weather resistance, weight, etc. are all basically the same." To meet your requirements, the optical performance of optical plastics is no problem.”
It was indeed good news, but it made Gao Zhendong extremely happy. Although Mr. Xiang said it more conservatively and said it was "basic," anyone who does research would understand this kind of wording.
Originally, he was a little worried. In his previous life in 1970, the semi-disposable rocket launcher still used a metal barrel. There could be a reason for this.
Without this plastic tube, the weight and cost of the metal tube, "one-time use" and "mass war" would be out of the question, and the advantage of not occupying the establishment would be lost. In this way, The promotion and use of this thing will be greatly affected.
Take the New 40 Fire as an example. In fact, the research on this thing was basically completed before 1969, otherwise it would not have been the first completed equipment in the "823" battle.
But this thing never entered the army until it was discovered that the old 40 fire could not chew the turtle shell of the old Maozi. It was not finalized until the beginning of the "823" battle in 1970. It was because of the positioning of this equipment and The old 40 fire is very repetitive. The huge output and equipment of the old 40 fire make it difficult to make a decision.
As for disposable packages, we need to start with differentiated empowerment, develop new tracks, upgrade new playing methods, focus on new pain points, create new scenarios, break application barriers, dilute user boundaries, vertically sink to the masses, and horizontally expand to The entire army strives to realize the multi-dimensional application of firepower in all scenarios where everyone has a weapon and can fight turtles.
Now Mr. Xiang’s words made him feel relieved. Never mind what the bad news was, at least the good news was good enough.
Gao Zhendong said happily: "This news is great, Mr. Xiang, thank you, it has solved my big problem. So, what is the bad news?"
Mr. Xiang’s answer gave him a deep understanding of what it means to have one thought of heaven and one thought of hell.
"The bad news is, it's difficult to mass produce." Huh? This makes people feel uncomfortable: "Xiang, what is the reason why mass production is difficult? The cost is too high?"
No, ABS is not too troublesome. Once it is finalized and rolled out, the cost will not be too high. Even if there is not enough oil now, you can still make some plastic tubes. Affordable supply.
"Well, the cost is too high, or the direct reason is that the processing is difficult and the yield is too low, resulting in high costs."
General Manager Xiang explained the reason to Gao Zhendong.
The reason why Gao Zhendong wants ABS is that it focuses on strength, toughness and high temperature resistance. After research, Mr. Xiang finally found the right balance point, and the ABS he created has all three aspects. Not very outstanding, but all three items are stuck above Gao Zhendong's demand line.
But this brings up a question. As a thermoplastic, ABS has high strength, toughness and high temperature. What does it bring? Difficult to process.
Not to mention injection molding, just these three things determine that this thing can only be extruded. Simply put, it means applying pressure to shape.
Then Mr. Xiang discovered that there were serious problems, including uneven mixing, uneven heating, difficult to control the extrusion speed, uneven discharging, large backflow, and poor plasticization.
And due to the long residence time of the materials in the extruder and uneven heating, the processing temperature cannot be raised at all. Otherwise, the high temperature and long time will make the products unusable.
The few bobbins used for the test were all lucky ones picked out from a pile of scraps by Mr. Xiang. He did the test to verify the feasibility. I think If you want to use it for mass production, it will undoubtedly be a fish in the woods.
Gao Zhendong dumbly listened to the introduction to the general manager and realized the seriousness of the matter.
Whether materials are available or not is one thing. It only solves the problem from 0 to 1. The difficulty of obtaining and processing is also decisive, which involves the issue of whether it can be used on a large scale.
In addition to titanium, another well-known example in this regard is aluminum. Aluminum was discovered quite early, but it was difficult to refine in the early stage. It had to be replaced with elemental potassium, and its worth was far more than gold. Napoleon III expressed great praise for this matter. He was proud of having a set of aluminum tableware.
Rumors say, the prototype of "mithril" often mentioned in Western Fantasy comes from aluminum.
Unexpectedly, Gao Zhendong solved the problem of the drug cover, the high-energy charge, and the propellant, but he was blocked by a shell. It was so shocking.
Wait, what was I thinking just now? Propellant.
Gao Zhendong fell into recollection. Mr. Xiang, who was opposite him, was speechless for a long time. He thought he had been hit too hard and comforted him on the phone: "Director Gao, you don't have to worry. Anyway, the materials are Yes, I will study the processing problem and improve the screw extruder. I think there is a way.”
Screw? Gao Zhendong remembered!
In the solid rocket motor textbook, regarding the propellant process, he saw this sentence - "In modern propellant charge molding, twin-screw extruders have begun to be widely used to replace single-screw extruders. Screw extruder, the former has better performance than the latter. "
For this reason, he also specifically read the relevant content about the screw extruder in this textbook. Well, it is quite contrary. intuition.
No wonder he couldn't remember it just now. It was mainly propellant and plastic. At first glance, the difference was a bit big. He also didn't expect that these two things could be processed by the same machine.
Gao Zhendong, who felt some hope, asked eagerly on the phone: "Mr. Xiang, is the extruder you use a single-screw machine?"
Mr. Xiang did not expect this. Gao Zhendong was also involved in the gadget and replied: "Yes, this is the most suitable machine for extrusion processing now."
Gao Zhendong laughed happily: "Haha, I understand, I understand."
After working on it for a long time, even in the top research institute in the country like Xiang Zong's unit, they are still using single-screw extruders. I still don't fully realize the difficulties of the technical environment at this time. degree.
What Gao Zhendong didn't know was that the twin-screw extruder used for thermoplastic processing was invented in the country of leather shoes in the 1930s, and began to develop greatly in the 1960s. Thinking about it this way, it seems that the country did not understand this stuff at this time. , it’s not too much.
Mr. Xiang is confused on the other side, what do you understand? I've been doing it myself for so long and I still haven't figured it out yet.
But he knew that Gao Zhendong would not just talk nonsense. Maybe he really discovered something, which made him very happy. Don't think that he is an amateur. At worst, Director Gao is also engaged in materials, and he has a wide range of knowledge. Very wide.
At least he can tell you the single screw he uses, which is no longer something ordinary people can know.
There is a way. With excitement and a hint of guilt, Mr. Xiang asked Gao Zhendong eagerly: "Director Gao, what did you find? Tell me quickly."
Gao Zhendong smiled and said: "I just have an idea, but it may not be accurate, but it is worth a try. Mr. Xiang, let's try replacing the single screw with an intermeshing twin screw?"
Mr. Xiang was stunned: "This Is there a difference? Just increasing the feeding speed within the same length still doesn’t solve the problem. ”
