Chapter 310 Is this thing happening in China now?
Gao Zhendong called his old acquaintance. This time, he was asking for help.
Gao Zhendong has no idea of doing it himself. He has met so many top industry experts during this period. If he doesn't integrate resources, wouldn't it be a waste of time to get to know them?
Mr. Xiang, who is engaged in urea technology, received his call.
"Director Gao, hello, hello." Mr. Xiang was very happy to hear that it was Gao Zhendong. It was rare to receive a call from Gao Zhendong. Although after the success of urea steel, the two of them had nothing serious to do at work for the time being. , but a call from an old friend always makes people feel happy.
The two exchanged pleasantries for a while, and then Gao Zhendong got down to business: "Mr. Xiang, this time I am asking you for help, hahaha."
Mr. If I don't ask for help, you help me every time. I won't be able to calm down if I don't regain some ground.
"If you need anything, just say it, Director Gao." He asked the general manager to do everything for him, since he had an entire research institute behind him.
"I want a kind of plastic and a batch of products."
"Plastic? Process?" Mr. Xiang confirmed and waited for him to continue, but did not ask. What it is used for, if you can tell it, you will naturally tell it.
"The requirements for plastics are relatively simple. Just try to use optical glass as much as possible. But the first priority is optical properties, transparency, which comes second. Then it requires easy processing, and preferably better injection molding accuracy."< br>
First of all, it must have good optical performance and uniform refractive index. Without this, everything else is useless. This thing is used to make a disposable sight.
As for the transparency, it is not a big problem if it is lower. Of course, under permissible conditions, the higher the better.
If the injection molding precision can be relatively high, the production will be faster. At worst, it will be simple manual grinding and polishing after injection molding.
No matter how you say it, it is much cheaper than an optical sight made of whole optical glass. These days, nothing that touches optics is cheap.
However, Gao Zhendong did not place all his hopes on Mr. Xiang. After all, he did not understand the capabilities of the chemical industry at this time. If this road failed, he was prepared to take the path of disposable mechanical sights. , at most, make an interface to provide a reusable high-precision optical sight, and distribute one to a certain number of barrels.
Hiss~~~~~~Director Gao’s request sounds simple, but it is actually a bit difficult, but Mr. Xiang did not back down. He carefully thought about the current situation he knew. This job will continue. .
Anyway, although blending fertilizer and compound fertilizer is of great significance, there are not many areas where he needs to exert his efforts, and it always feels a bit unsatisfactory.
"Director Gao, your request is not simple at all, but it is much simpler than urea steel. I will take this job. No problem. Just wait for my good news. . What is the product you are talking about?”
Gao Zhendong smiled: “Roll the fiberglass into a tube with a diameter of 80 mm, and the length is from 700mm to 1000mm. The fiberglass itself must be able to withstand a certain high temperature. , the strength is better. In short, in the three directions of temperature, strength and weather resistance, you can use the best materials in China, provided that they can be mass-produced and are not expensive.”
Fiberglass tubes are light, cheap, and corrosion-resistant, but I don’t know if they can be solved now. If Gao Zhendong remembers correctly, even ten years later, this matter has still not been completely solved.
However, there are many reasons why it is not solved. It is not entirely the problem of FRP, but the design, which requires FRP to withstand high pressure under the premise of being lightweight. This is a bit difficult under the conditions of ten years. It is beyond the capabilities of fiberglass.
The difference with PF-89 is that the barrel mainly functions as a directional tube and a storage and transportation protection tube. It does not need to bear too much pressure. Anyway, it is enough to fire the rocket out smoothly without burning the shooter. It doesn't matter what kind of bird it is burned into after the beating.
Gao Zhendong did not specify the specific parameter requirements, mainly because he still doesn’t know to what extent they are required, so his idea is relatively simple. Get the best existing ones and try them. If it doesn't work, he also has a backup plan - painting a thin stainless steel tube. Although it may be important, it doesn't mean it can't be used.
Mr. Xiang was very happy when he heard it. What are you doing with it? I don’t understand it. I don’t understand it at all. I can’t guess it at all. Hehe.
However, this request was rejected by President Xiang. Instead of rejecting it, another plan was proposed.
"Director Gao, fiberglass is also troublesome to process. How about I recommend another thing to you?"
Gao Zhendong was stunned, are there any experts?
"Well, Mr. Xiang, please tell me."
"Our unit is working on a new type of plastic, which is a terpolymer with relatively excellent properties and can be adjusted The ratio of the three components can produce plastics with different performance characteristics. The overall characteristics are hard, tough and rigid, and the temperature resistance can be adjusted. ”
When Gao Zhendong heard this, he was stunned. Did this thing start to appear now?
Mr. Xiang added: "And this thing can be extruded or injection molded, and the processing performance is very good."
Gao Zhendong was even more sure after hearing this, so he didn't run away. Definitely. The thing Mr. Xiang is talking about is undoubtedly ABS engineering plastic. It is a terpolymer composed of acrylonitrile (A), butadiene (B), and styrene (S). It is cheap, has excellent performance, and can Special adjustments are made according to different components.
It is said that this material is most suitable for use in disposable barrels. The reason is - PF-89 uses this as the launch barrel, and the material accounts for more than 80%. !
Even its sights, except for the optical plastic part, are made of ABS.
Why don’t you say that 89 tubes are cheap?
However, Gao Zhendong only knew that the introduction of ABS in China was in the 1960s. He did not expect that 1960 was also the 1960s.
After thinking about it, this is normal. In such a big country, it is not just one person who is engaged in technology.
This was an unexpected surprise for Gao Zhendong. It was stable and he immediately listened to the advice: "Then this! The specifications are still the same as just mentioned, and the requirements are still the same as before, what about the weight? , within the range of 1.5kg to 2kg, improve the performance as much as possible and keep the price down. As for the related procedures and expenses, you don’t have to worry about it, I will consider it.”
The barrel weight of the 89 barrel is about 1.8kg, and the bullet weight is similar. Of course, Gao Zhendong cannot rely on this data. It would be too difficult for Mr. Xiang. After all, the materials and performance at this time are still not as good as those of the 89 barrel. Therefore, Gao Zhendong gave a broad range.
As for the price, it must be kept low. Gao Zhendong’s purpose in developing this thing is that it is a one-time thing that can be equipped on a large scale, not only for the regular army, but also for the guerrillas, militia, and local armed forces. In short We don’t want high technology, but we need to cause enough trouble for high technology.
In fact, this is not correct. On the premise of meeting the requirements, try to lower the mass production price, simplify the production process, and lower the threshold for use. This is a high technology in itself.
It’s just that this high technology is reflected in the research and production management process. The lower the technological content of the product itself, the better.
I wonder if it can become the fourth greatest guerrilla artifact. Gao Zhendong almost laughed out loud when he thought of this.
AK-47, RPG, and 105 rockets, except for the 105 rocket originating in China, in fact, we owe a lot to the fame of the first two. Moreover, although the first two have the same name, how many of them are 56 punch? It's hard to say how many 40 fires it is.
Mr. Xiang was very happy to see Gao Zhendong listen to the advice. As a professional, it is undoubtedly a great sense of accomplishment to have a technical expert follow his advice.
"Okay, Director Gao, these two matters have been settled. As for the funding issue, you don't need to worry about it. You still have to pay for the funding for urea steel. I will handle this matter here. , just put it in ABS plastic as an accessory project. "
We Chinese people are still very particular about this matter. When the 17th Machinery Department was working on urea steel, they just paid for it out of their own pockets. We in the Department of Chemical Engineering cannot afford to lose face like this, right?
Gao Zhendong is also welcome. Anyway, the rice is all in the same pot. It would speed up the process by reducing the trouble in the process.
However, he still said a few words according to his memory.
“In ABS plastic, butadiene increases toughness, acrylonitrile and styrene increase strength, weather resistance, heat resistance and processing performance. Processing is suitable for high material temperature and high mold temperature, but too high is not enough. If it is convenient, I also hope that Mr. Xiang can do more experiments for us to find the most suitable ratio and processing method.”
This makes Mr. Xiang stupid. We have just started, and you already know?
In fact, if he hadn't said the name ABS directly, it would have been inconvenient for Gao Zhendong to say these words. After all, you can't predict the future.
But now that the name ABS has been told to the president, Gao Zhendong can say that he just looked at the materials and analyzed it based on the characteristics of the three-component components. There is nothing wrong with it.
"Director Gao also understands this?" Mr. Xiang never expected this. He not only understands metal materials, but also plastics?
“I’ve heard a little bit about it, but I’m definitely not as professional as you, so I’ll leave this matter to Mr. Xiang.”
You’ve heard more than a little bit, ABS It's a new thing in China. It hasn't been long since we started. Just those few words you just said can save me a lot of things, especially in processing. We haven't gotten to that point yet.
However, he did not resent Gao Zhendong’s dictating attitude. Instead, he felt that he was highly cooperative, had a wide range of interests, was easy to communicate with, and could provide a lot of help to his work.
The person you communicate with is knowledgeable, which is a double-edged sword. The advantage is that communication is smooth, information can easily be fully exchanged and analyzed, and things can be better promoted.
The disadvantage is that everyone in sales understands it, and Party A understands it so well that it becomes difficult to deceive them.
However, in Mr. Xiang’s case, it is obvious that he has a deeper feeling for the former.
