Eighty-year-old Little Wife Earns 100 Million with Space

Chapter 2568 He's actually a smart guy.

Xu Haixia walked in front and said: "The scientific name of polyester is polyester fiber, which is polyester formed by condensation of polyethylene glycol and terephthalic acid. By drying and melting polyester sheets, they can be spun. Different processes can produce Polyester filament and polyester short filament are then processed to produce the polyester fabric you saw earlier.

During the college entrance examination, Tao Yongan's physics and chemistry scores were average, and he mainly devoted himself to improving his Chinese and political scores.

He doesn't know much about the so-called chemical experiments, just to supplement his knowledge of physics, which has made him dizzy for a while.

But he's actually a smart guy and gets to the point quickly, "So what we need to do now is go beyond this polyester
First, the oil is broken down into polyester.

Then we'll look at how polyester fibers can be made into the cotton fibers they need.

In this process, Xu Haixia's knowledge reserve is also insufficient.

I can only grope slowly.

But why should we experiment on our own?do you want to apply for a patent
Are there patents on something like copyright?

Xu Haixia smiled bitterly and said: "You think too much, I just want to find a way to reduce the cost as much as possible. Tao Yongan, we are very poor

Not only were the two of them in partnership, but the entire country was poor.Even if they produce sanitary napkins, many female compatriots are reluctant to use them.

So what can Xu Haixia do?

It is indeed a hassle-free trip to the chemical plant.They are students of provincial universities and can go to workshops with their certificates.

But chemical plants have their own processes and production tasks. How can anyone listen to a student's chat?
What Xu Haixia can do is to make fiber cotton by herself to reduce the cost as much as possible.

So experimentation is essential.

We need to do more than fiber cotton.Working on polyester, we also need to make a waterproof layer, otherwise the blood will be partially absorbed by the fiber cotton and still seep through

That's right, that's right.Tao Yongan asked, taking out the blueprint stuffed in his pocket.By the way, what is that gray patch you painted

Still inconvenient if the backing is not fixed

Tao Yongan thought for a while: "You are really thoughtful.
He originally wanted to praise Xu Haixia strongly, but after he said it, he felt inexplicably sad.

The reason to think about everything is that I have suffered many crimes before.

Well, great talent, let's not hurt Chunqiu.Let's do an experiment together.I need your help, that's right
Xu Haixia didn't want to attack Tao Yongan repeatedly.

Despite this, she herself was repeatedly beaten.

What is something as simple as an experiment?
Although Xu Haixia used to study science and engineering and electrical automation, he couldn't keep up with chemical engineering.

Basic knowledge is reliable, but if you want to come up with something, you can only fail and struggle again and again, and the more frustrated you are, the braver you are.

For Xu Haixia, simply cracking oil and then chemically processing it to produce benzoic acid has been a troublesome task for half a month.

Xu Haixia took the wrong path, and his senior brother in the laboratory reminded him that benzoic acid is not easy to refine, so he could try using benzyl ester instead.

That's how they do polyester homework, the teachers are blind anyway.

There are finished products that are great, how can we expect these students to come up with something real?
Xu Haixia tried it, and it was indeed possible.

However, the obtained polyester fibers were of poor quality.

After slicing, it is particularly rough when observed under a microscope.

Start from scratch.

Xu Haixia could only find a way to deal with the benzoic acid.

The predecessors of the laboratory are not optimistic.One of them secretly said to her: "I have read foreign reports before, saying that they spent several years purifying benzoic acid
What were their experimental conditions?The laboratory of their chemistry department is very simple, and they even have to cherish the use of test tubes.If they broke one, they would have to make up for the trouble caused.

Tao Yongan comforted Xu Haixia and said: "We have been making mushroom eggs abroad for a long time. How long have we been using them? Don't worry, I believe you

Although Tao Yongan himself felt a little depressed after leaving the laboratory
He didn't know how to comfort Xu Haixia, they worked very hard.

In 1350, I came to the laboratory of the chemistry department. In 246, the laboratory of the mechanical department was very busy, and I had to do translation to make money.If Xu Haixia studies well, she needs to help students in this major answer questions.

24 hours a day is simply not enough.

However, he still couldn't make a breakthrough.He watched Xu Haixia's smile getting more and more nervous, but he didn't know how to comfort him.

Xu Haixia was also a little tired.After returning to the dormitory, the roommates were discussing a problem, and mathematics was their biggest challenge.

This is your letter, sent by Comrade Xiao Xie.Chen Fangyuan pointed at the table and smiled mysteriously.Xiao Xu, do you have many contacts?

She went to the mailroom every few days and had already brought three letters to Xu Haixia.

I have some questions to ask him.Xu Haixia was a little perfunctory, but she was just chatting casually.

Under great pressure, some way of venting is always needed, so after that reply letter, Xu Haixia took the initiative to reply to Xie Wenkui with a letter about her recently translated book.

This overwhelming reading experience was actually more of a frustration caused by her failed experiment.

It's really annoying.

Two letters a week, the first one has not been received, and another one came.The two pen pals chatted a few words, mainly because Xu Haixia's mind was jumping, and Xie Wenkui also accommodated her.

Xie Wenkui wrote back and sent a photo. In the upper left corner was Comrade Xiao Xie's handwriting - "Spring in the Forbidden City".

In April this year, I went to the Forbidden City to help maintain the pipeline and borrowed a camera to take a photo.I just received the photo a while ago and wanted to send it to you

The vast Forbidden City slowly ushered in spring.

There are no cultural relics in the photo, only a corner of the red-walled hall and a touch of green.

A field of dead red and vibrant green shoots.

Xu Haixia smiled and said briefly: "Thank you Comrade Xiao Xie. I really like this photo. If you have time, come to the provincial capital and I will treat you to dinner. You helped me solve a big problem
How glorious is the centuries-old palace, how can these new greens suppress the palace that represents imperial power?
The once prosperous imperial power was now a dim red.

It is this kind of tender green that quietly climbed up the wall.

time.

She needs to be patient and give herself some time.

You can't rush hot tofu.

Chen Fangyuan looked at Xu Haixiabao holding the photo to his chest, and asked cautiously: "Is this really not your goal?"

yes do you want to take a look
Xu Haixia has always denied it, but now this sudden sentence caught Chen Fangyuan by surprise.

Huang Chunhua hurriedly said, "Look, who is afraid of whom?"

That's it, whoever is afraid of whom.

Xu Haixia handed over the photo, causing dormitory 205 to roar, "Xiao Xu, are you kidding me?
Just a broken leaf, what an amazing thing!
The girls laughed happily, and Xu Haixia felt much more relaxed.

The constant losing and fighting has really demoralized her for the past half month, but now she can sleep peacefully at night.

On Friday, Xu Haixia went to the laboratory after class.

The brothers and sisters in the laboratory are already familiar with her, and even joked: "How many times have you both failed? Why don't you take a two-day rest first? Maybe you will suddenly succeed."

Xu Haixia said with a smile: "Failure is the mother of success. Maybe she can succeed today,"

The senior brother was startled by this cold joke and ignored it.He drank too much and was in a hurry.

Seeing that Xu Haixia was in a good mood today, Tao Yongan quietly asked her: "Is there any way?

No, I just don't think we can rush.let's try again

Crack oil, try again to synthesize phthalates, and make polyester.

In elongated test tubes, organic chemical reactions are taking place.
