"Don't go. ”

"This seems to work. Director Zhang Yuanwen stood up and grabbed Jiang Jiuling enthusiastically, "Let's study and study." ”

"This shouldn't be difficult, as long as the tensile accuracy of nylon wire or glass wire is done well. ”

"It's because it's not that hard that we have to make it in a hurry. Zhang Yuanwen is a doer, and there is no shortage of these messy industrial materials in the Industrial Committee, so he quickly dragged Jiang Jiuling to a row of bungalows at the back of the building.

This is where the materials room, the laboratory, and the testing room are located.

Here I have to introduce the functions of the industrial committee.

The full name of the Industrial Commission is the [Science and Technology and Industrial Management Committee], and it has many functions.

They are:

Responsible for the certification and service of the Code of Sacred Industries.

Responsible for the social welfare of engineers and scientists, as well as the guarantee of work benefits.

Responsible for the management of extraordinary, Class I, Class II and other special industrial tools and equipment.

Responsible for organizing the formulation and revision of national and industry standards and technical specifications related to the science and technology industry.

Responsible for product certification, supervision and management of industry and technology, and provide quality and technical services for factories and state-owned enterprises.

In summary, everything related to the Sacred Industrial Code is managed by the Industrial Commission. This institution, which was established on the basis of the legal code, has great powers and capabilities, and is also one of the important institutions of the state.

Director Zhang Yuanwen brought Jiang Jiuling to the laboratory.

In the laboratory, there are four testers in white coats working inside, and there are also some old experimental instruments that Jiang Jiuling thinks can be used as "antiques" to be displayed.

Seeing Director Zhang Yuanwen coming, several experimenters nodded and said hello, but when they saw Jiang Jiuling behind him, they didn't say anything.

Zhang Yuanwen asked, "Is there nylon wire?"

"I remember yes, I'll look for it. An older experimenter put down his work, ran to the material room next door, rummaged through, and finally brought two bundles of white balls of thread wrapped around a hard cylinder.

"Director, this is a sample of nylon thread produced by a chemical factory in Wucheng. Nylon thread is a thread made of nylon material, director, can you see if it meets the requirements?"

The experimenters didn't know what Director Zhang Yuanwen was going to do when he brought a student in. However, several directors of the Industrial Commission have titles conferred by the Code, and the directors who are engaged in scientific research are most fond of tinkering with those scientific and technological products on weekdays.

Of course, most of these technology products are chicken ribs.

Zhang Yuanwen untied a nylon thread, which looked a little similar to a fishing line, but with a little less transparency.

"I don't think so. Zhang Yuanwen found that the nylon thread was too soft and tried to bend it, but as soon as he released the nylon thread, it would bounce back immediately.

"What do you think?" Zhang Yuanwen asked Jiang Jiuling again.

Jiang Jiuling thought to himself, this is not obvious, of course this nylon material is not good.

Nylon is the most important material in the textile and fiber industry, and there are so many of them that even Jiang Jiuling can't determine how many there are, and there are dozens of commonly used types alone.

This can't work, but Jiang Jiuling knows that nylon 46 is suitable for making practice tools.

Nylon 46 has the characteristics of high crystallinity, high rigidity and high strength, and the filaments made with it will not deform and rebound.

I know, but I can't say it.

The production process of nylon 46 is very complex, even in the 21st century, many chemical plants will inevitably encounter serious problems of bubbles and degradation during intensive training.

So Jiang Jiuling suggested: "Let's try fiberglass." ”

"Is there fiberglass?" Zhang Yuanwen looked at the experimenter beside him, who shook his head and said no. Fiberglass is not used for experiments at all, they usually deal with textiles and chemical materials, fiberglass should be found in the glass factory.

"Any innovation requires us to make a hundred times the effort, and we can't be afraid of trouble when we engage in scientific research. ”

Zhang Yuanwen took out an address book from his pocket, flipped through a few pages, and turned to the contact number of a glass factory in Wucheng, "Xiao Liu, you call this glass factory and ask if they can produce some glass fiber." ”

"It's best to have a fiber diameter of 0.1 mm, and the finer the better. ”

There was a phone in the laboratory, and the experimenter Xiao Liu turned on the phone speakerphone and called it.

"Hello, this is Jinhui Glass Products Factory, what's the matter?"

Xiao Liu first indicated his unit, and then asked them if they could produce fiberglass?

"Fiberglass?" said a loud voice on the other side of the phone, and he asked inexplicably what fiberglass was.

"You produce glass, don't you even understand glass fiber?" Xiao Liu helplessly explained: "It is to draw the glass into fine filaments, which are about as thin as a hair, or if they are thinner, they are called fibers." I've heard of fiberglass, it's made of this fiberglass. ”

There was silence for five seconds, "This comrade, you made the wrong call. ”

"Our Jinhui Glass Products Factory is all about the production of canned bottles, window glass, and glass handicrafts. ”

"Our master can blow out a glass dragon with his mouth, and he can also use an angle grinder to grind a landscape painting on the glass. You are talking about the high-tech of fiberglass, I suggest you ask Shanghai Glass Instrument Factory. ”

After the phone was hung up, Zhang Yuanwen repeated that you can't be afraid of trouble when you engage in scientific research, and then continued to flip through the address book.

He had the contact number of Shanghai Glass Instrument Factory, but he was hesitant to make this call.

Because this is not a factory in Wucheng, I didn't expect this kind of hair-thick fiberglass to be so difficult to handle. Shanghai Glass Factory is likely to be troublesome and refuse him, and he can't give much money for this kind of private customized products.

Zhang Yuanwen closed the address book and decided not to make this call.

"We can't be afraid of trouble. ”

"Fiberglass is not easy to get, so let's use our brains together to see if we can replace it with other materials. ”

"As long as it can be very thin, it can be bent at will without deformation. ”

Several experimenters said in unison, "That's a thin wire." ”

Zhang Yuanwen said in a tone that I am not stupid: "Iron is not good, non-metallic materials are required." ”

Of course, Zhang Yuanwen is not stupid, in fact, after Jiang Jiuling said this scheme of moving through filaments, he has been thinking about what materials can be used.

But after thinking about it, he felt that glass filament was the most suitable. But now the road of glass filament is a little difficult to walk, so I can only find other materials.

Seeing a few test personnel looking around, Zhang Yuanwen was a little hopeless and said, "Jiang Jiuling, do you have any suggestions?"

"Director, I think it's just experimental, but I have a way to make fiberglass quickly. ”

"Are you kidding, Jinhui Glass Products Factory said there is no way, let's find an instrument factory. ”

"It's actually very simple, you can make it with the equipment in the laboratory. Jiang Jiuling actually didn't want to look very tricky in front of them, because he was only a high school student now.

But Jiang Jiuling wanted to go home early.
