The journey starts from the Titanic

Although he could not name his name, he knew that this thing was of great significance to the Dasheng Group.

"What is this again?" he asked.As I asked, I pulled the silk thread and rubbed it hard. The silk thread was as tough as ever, without any deformation.It's the legendary silkworm!

"Dr. Carothers, you can introduce our baby to this textile owner!"

Situ Nan smiled.

With a reserved look, after the Giant Lab invented nylon rope, he was the first beneficiary, and made modern guitar strings with copper wire on the outer ring of the nylon rope.

If you don't disassemble the copper wire on the outside of the guitar strings, most people really won't find the high technology inside!

Even the women and children at home don't know this.

"We use glycols and dicarboxylic acids as raw materials to synthesize long-chain polyesters with high molecular weight through esterification and condensation. Then, through this polyester, we will further research and obtain high-molecular-weight polyesters.

Under high temperature conditions, these high-polyester melts are as sticky as marshmallows, and crystal clear glass fiber can be drawn from them. After cooling and stretching, the fiber's strength, elasticity, transparency and gloss are greatly increased."

The circumflex and frustration that Carothers said, based on the example of pulling marshmallows and glass wool, made the manufacturing process vivid and concrete, and others would understand it.

Of course, how to get those magical marshmallow melts is very complicated.

"Synthetic fibers made from unknown polymers! I see!"

Zhang Xiaoruo nodded, remembered the name, and asked how does it compare to traditional cotton?

Carothers looked at the assistant next to him, and immediately there was an equally young scientist who stood up and said: "Ten times more durable than cotton, and 20 times more resistant to wool. No matter how you fold it, it will keep on folding.

Knowing that this yellow-skinned rich man is a textile owner, the scientist added, "If this synthetic fiber is added to the textile species, the quality of the product will be magically improved."

Zhang Xiaoruo said this to his heart. He nodded excitedly, looking forward to these magical fibers appearing on the raw material list of Dasheng Textile Factory.

However, it turns out that he was still too impatient.

I saw Carothers regretfully saying: "Although our baby has many advantages, it is still a problem in heat resistance. We have not found the most suitable and economical polyester and polyester materials to make this kind of synthesis. fiber."

"In other words, we haven't found one percent of the various polyester compounds?" Situ Nan asked.

"If you are not afraid of losing money, I am afraid that is the case!" Carothers laughed.

There are too many high-molecular compounds. Similar substances and different molecular weights cause the properties to change. Carothers has done a lot of experiments on polyester compounds, but the results are not too ideal. The next step is to focus on other high polymers. on.

The most important thing is that the correct method has been found. The next step is to find out the experiment, one polymer by polymer, there is no shortcut.

The reason is probably the same as the alloy formula. Different formulas have different properties. Thousands of experiments have to be tested, which is a great test of manpower and material resources.

Situ Nan understood this truth.High-tech is about burning money, so he has patience.

For nylon, um, the name nylon has not appeared in other people, even the inventor, Carothers, already in Situ Nan's mind.

He happened to know a little bit of information about nylon, and it was very crucial.

"It's a pity! If the raw materials are sufficient, Dasheng Textile Factory can produce countless textiles for the world."

Zhang Xiaoruo expressed regret.

"But related research has to be carried out!" Situ Nan exhorted.

It is reminded that Dasheng Loom Company should research suitable textile machines for synthetic fibers.

Zhang Xiaoruo nodded.

"Perhaps a better comparison is polyester and polyamide, polyamide synthesized from ethylenediamine and oxalic acid." Situ Nan thought for a while, then slowly said.

Carothers looked at Situ Nan with a little surprise, he was noncommittal about Situ Nan's words, and looked at Situ Nan's confident manner, with doubts in his heart.

Situ Nan did not mention the direct polyamide 66. The first 6 represents the number of carbon atoms in the diamine, and the second 6 represents the number of carbon atoms in the diacid. This is too scary!

No one is omniscient except God!

But if Carothers didn't find the answer in two years, Situ Nan wouldn't mind speaking more clearly.

I saw his face changed slightly, his mouth moved, he wanted to say something.

Chapter 190

Carothers was a little surprised and couldn't help but look at Situ Nan, his eyes seemed to ask-how did you think of this?The reason?

Situ Nan faced Carothers calmly, as if he was saying---I'll just talk about it, you will know if you try.

Carothers could not see any problems in Situ Nan’s eyes, and Situ Nan did not answer his doubts directly. He said to his heart: Anyway, the comparison test is done for one type of substance. Since the boss has spoken, it is not a principle. Sexual issues, it doesn't matter if you listen to him once.

Thinking of this, Carothers nodded slowly and glanced at the assistant next to him. The assistant quickly understood and nodded, giving oxalic acid and ethylenediamine as the priority test subjects.

"The bright future is right in front of us. The opportunity to change human history has arrived. You have caught the foot of the goddess of victory, and work harder to lift off her skirt! Guys!"

Situ Nan sensationally encouraged Carothers and his organic chemistry department.

Carothers and others didn't have any sense of humor, or the engineering male was introverted. He just chuckled and didn't let it go. Situ Nan's bold words did not get a strong response.

It gave them a lot of confidence, at least to guarantee their organic chemistry department a million dollars in research funding.

Speaking of nylon, what do people think of first impression?

Naturally it is silk stockings!

In fact, the application of nylon is very broad. Stockings are only one of the fastest applications that reflect economic benefits. When Situ Nan left the giant's laboratory, he specifically asked Carothers to make a small batch of polyester yarns smaller than guitar strings.

Well, it's pretty silly, who made the real nylon 66 not appear yet!

How to put the results of the laboratory into practical use will test the technology of Giant Chemical Company.

The top priority is to cooperate with the laboratory to develop related industrial equipment and formulate industrial processes.

Situ Nan gave instructions to Giant Chemical Company. Giant Chemical Company was unable to build those high-pressure, high-temperature and corrosion-resistant reactors. He also asked Cummins Electric and Bethlehem United Steel to jointly develop reactors suitable for polymer polymerization. Decomposer, polymerization kettle and other equipment.

Under the instigation of Stuart, several large companies such as the Giant Chemical Company Cummins Electric Company Bethlehem Steel Co., Ltd. jointly tackled key problems, invested a lot of manpower and material resources in research and development, and quickly made breakthroughs in stainless steel alloys and welding technology.

An experimental reactor was set up and produced experimentally based on the research results provided by Dr. Carothers.

Regrettably, Carothers followed Stuart’s suggestion and used oxalic acid and ethylenediamine as raw materials to carry out polymerization experiments. The progress was very fast and many breakthroughs were made. However, it was not so lucky to find nylon 66.

Situ Nan didn't mind this little flaw. Using the automatic loom provided by Dasheng Loom Company, the textile laboratory jointly established by Dasheng Company and Giant Chemical Company finally produced the first pair of stockings!

Laura found out that Situ Nan had been returning from the Giant Chemical Company and had been secretive, not knowing what he was messing up with.

When Situ Nan said mysteriously that she wanted to give her a gift, she still didn't take it seriously. Is there anything else she hadn't seen?He didn't take it to heart, and said, "You stay with me at home and don't run around. It's the best gift."

This day, a sunny afternoon, well, California’s sunshine is always so good!
