Zhang Yuanwen and several experimenters were obviously unconvinced.

They know what equipment is in the laboratory, and it can be used for testing and testing, but it is obviously impractical to use it to produce glass fiber.

When this sentence was uttered by a seventeen or eighteen-year-old high school student, it became even more implausible.

"That'...... You try?"

If you don't believe it, Zhang Yuanwen has not been so arbitrary that he didn't even give him a chance.

He asked Jiang Jiuling what he needed.

We should not be afraid of trouble in scientific research, and at the same time, we must believe in miracles.

What if this kid can really pull glass into fiber?

"I need a piece of pure glass, an acetylene gas cutting gun. Since he decided to show his hand, Jiang Jiuling did not hesitate, he easily took a set of white coats from the wall behind the laboratory door and put them on his body.

Jiang Jiuling may have stayed in more laboratories than he has ever opened a hotel.

After washing his hands in front of the sink, Jiang Jiuling waited for a long time and didn't see anyone leave to look for materials, so he couldn't help but ask suspiciously, "What's the problem?"

Zhang Yuanwen asked, "No?"

"What's gone, no acetylene gas cutting gun?"

"I mean you don't need other materials?" Zhang Yuanwen couldn't believe that there were only two materials to make fiberglass.

One of them is still high-purity glass, and of course glass is required to make fiberglass.

What about acetylene gas cutting guns?

This thing has nothing to do with high-tech, Wu Cheng but any factory that deals with metal, which one does not have this kind of thing.

"Hmm~ may also need a needle-nose pliers. Jiang Jiuling thought for a while, "It would be more convenient to have another tongs for burning briquettes." ”

Zhang Yuanwen looked at Jiang Jiuling, and then at several quail-like experimenters next to him.

An experimenter reacted, and Ai Ai said, "There should be a ...... over there in the boiler room There are tongs, so I'll go to the boiler burner and ask for one. ”

......

In fact, the technology of making fiberglass is not complicated.

The most common production techniques for the production of glass fibers are glass drawing towers and glass drawing machines.

The wire drawing machine requires more equipment and high technical difficulty, but the wire drawing tower technology is much simpler.

It took less than ten minutes for Jiang Jiuling to get what he needed, and these ten minutes were mainly spent carrying the acetylene gas cutting gun from the warehouse to the third floor of the office building in front.

This thing dragged two atmospheric bottles with a combined weight of almost 300 catties, and when the four experimenters resisted to the third floor, they were so tired that they didn't even have the strength to question.

"In the past, Galileo Galilei threw iron balls at the Leaning Tower of Pisa, and today there are high school students who use glass to make fibers on the third floor. At the same time that Zhang Yuanwen moved Yu Jiang Jiuling, he also looked around, but fortunately, no one around was watching the excitement.

The third floor is filled with archives, conference rooms, and a few offices where work is relatively leisurely.

There are only a few veteran comrades in the office who have retired to the second line due to their age, and they are still taking a lunch break in their rooms at this point.

It's good that no one watches the excitement, otherwise someone will definitely laugh at him Director Zhang and mess around during working hours.

"It's not changing, it's burning. Jiang Jiuling, who was wearing labor protection gloves, smiled at him, and then motioned to the nearest experimenter, "Please come over and light the gas cutting gun." ”

In the past, Jiang Jiuling was the boss of the department, and everyone had to listen to him. From middle school to university, he also served as a class president, or the president of the science and technology club, and he was used to calling people.

The experimenter, who was so tired that he was out of breath, gave Jiang Jiuling a blank look. If it weren't for the gas cutting gun, it would be a bit dangerous for a high school student to ignite a fire, so he wouldn't want to move. The high school student in front of him has a big voice, a bigger shelf, and likes to make people do anything.

The experimenter said angrily: "Will you use it?"

"Yes, we used this in our tech club at school. ”

The gas cutting gun was ignited, Jiang Jiuling first adjusted the acetylene valve, and when he heard the whistling sound, he began to adjust the oxygen switch. The original blue flame turned white in an instant, and the roar of the flame was like the roar of a wild beast.

Jiang Jiuling summoned again, "You come and clamp this glass rod with fire tongs." ”

One of the experimenters did so, and the glass rod he had turned out of the warehouse, which was originally used for electrostatic tests, was now used as a wire drawing material.

It's just that this glass rod looks very average in purity, and even in the sunlight, you can see that there are many small pores inside.

When the scorching white flame just sprayed onto the glass rod, the experimenter's scalp suddenly went numb, and he subconsciously stretched his arm forward again, widening the distance between the flame and his body, "Acetylene gas cutting thumb-thick steel plates is like cutting tofu, you have to take it easy." ”

Zhang Yuanwen and several other experimenters took two steps back when they heard this, no matter how steady Jiang Jiuling's hand was, they would not trust a high school student too much.

Jiang Jiuling didn't speak, just focused on watching the changes of the glass rod at the high temperature.

Depending on the material, the melting point of glass is also different.

The melting point of ordinary glass is generally 600-800 °C, and now the flame temperature has been adjusted to between 1000-1400 °C.

In less than five seconds, the end of the glass rod began to turn red.

Jiang Jiuling immediately took away the flames, and with his right hand with labor protection gloves, he picked up the needle-nose pliers to clip the red end of the glass rod. Softening has begun here, and it's easy to clip a nib-like cone shape at the end with needle-nose pliers.

"The tongs are holding it firm. ”

Jiang Jiuling explained, turned down the flame, and then slowly burned the end of the glass rod.

A magical scene happened.

Under the scorching flames, the cone that had been pinched by the needle-nose pliers began to slowly droop like syrup.

From the thickness of the nib, it becomes thinner and thinner in the process of sagging.

By the time it reached the second floor, it had become the thickness of a fishing line, but by this time, because the glass cone in front of it had broken away from the flames and cooled in mid-air, it stopped sagging and became solidified again after reaching the second floor.

Zhang Yuanwen opened his mouth wide, unconsciously looking at the scene in front of him.

Several other experimenters rubbed their eyes.

"Not qualified. Jiang Jiuling shook his head and easily pinched the fiber more than three meters long with needle-nosed pliers.

The transparent fibers drift like a thread in the wind, and soon they are no longer visible.

"Holy, you...... Why are you breaking it?" a tester glared at Jiang Jiuling, and then hurriedly ran downstairs to find the fiber.

"It's too thick. Jiang Jiuling re-clamped a smaller cone at the end of the glass rod with needle-nose pliers.

Under gravity, the dripping speed of the glass cone has a certain relationship with its own temperature.

The higher the temperature, the softer the glass cone and the faster it falls. Of course, if you fall quickly, it is easy to tear yourself off.

Then in the absence of a thermostatic heating chamber, it is necessary to repeat the attempt.

This attempt will not be too many times, after all, there is no particular attention to its specific thickness, and it will be okay with the naked eye.

So for the third time, the fiberglass becomes a filament that is difficult to detect with the naked eye.

This time, Jiang Jiuling did not discard it after cutting it off with needle-nose pliers, but took advantage of the fact that it had not completely cooled down, grabbed the filament with labor protection gloves and wrapped it around a few times, and wound it into a ball of thread.

In the attention of several people at the scene, this glass fiber ball slowly began to rebound under the residual temperature.

From the initial fist-sized, it rebounded to the size of a desk, and then cooled down and stood still.

Jiang Jiuling looked at the maze-like intertwined glass fibers on the ground, and said with satisfaction: "I think it's okay." ”
