Chapter Three Hundred and Three Misunderstandings

But now we don't have any solution, we can't hold back the entire project, Ma Sixing said helplessly.

There is nothing to worry about. The original plan for this bridge was to be completed in May 2020. There are still eleven months to go. There is no need for us to take risks. Chen Wenfeng still rejected the thermal expansion and contraction casing plan.

Oh well!

Lao Ma, your plan is still good. Please continue to improve it as a backup just in case.

I will continue to follow up on this plan.

The two of them ate breakfast in a hurry and continued to study how to solve the joint sealing problem.

Even welding is not possible. After all, metal pores may be formed after welding. These pores have no major impact on items or facilities that do not require high sealing properties.

However, the vacuum pipeline with high vacuum is not good at all. Even a small air hole may cause catastrophic consequences.

In addition, the bonding between the welded metal and the graphene composite FRP material was not good, so the welding solution was eliminated.

Next, a researcher proposed a concrete wrapping method, using foam cement to wrap the pipe joint.

The strength of foam cement is sufficient, but you will not forget the congenital defects of foam cement. Ma Sixing obviously does not approve of this plan.

What is the congenital defect of foam cement? It is that the sealing performance of foam cement is not good. When used as a wall, special anti-penetration materials need to be applied to avoid water leakage.

What's more, for vacuum pipes with such high vacuum requirements, as for using ordinary concrete, it is better to use Masixing's thermal expansion and contraction casing solution.

Sorry, I didn't think of this question. The researcher said awkwardly.

Chen Wenfeng waved his hand: No need to apologize. Everyone is here to solve the problem. Let us know what you think. A stone from another mountain can attack a jade.

All the researchers were racking their brains and thinking hard. Some were looking through materials in the library, some were searching in the internal journal article library, and some were simply closing their eyes and meditating.

As a student of Galaxy College last year, Jiang Guoyu has been assigned to the Vacuum Pipeline Research Institute as an intern for more than two months.

Although they are all doing odd jobs, Galaxy Technology does not exploit these interns, and they still receive all the wages and benefits they deserve.

Based on their performance during the internship, Galaxy Technology will make arrangements for these students after graduation. Whether to stay or leave depends on their performance.

If you perform well during the internship, it is not impossible to become a full-time employee early.

Therefore, Jiang Guoyu cherishes the opportunity to intern at the Vacuum Pipeline Research Institute.

He was also thinking about how to solve the problem of sealing the joints of vacuum pipelines. Like some people, he chose to read materials and papers.

Suddenly he saw a paper "Ab Gel Laser Welding Technology" that was uploaded just this morning. Jiang Guoyu didn't pay attention to it at first. After all, in Galaxy Technology's internal journals, there are hundreds to hundreds of such papers.

But soon he lost his composure because he saw the author of the paper.

The three words Huang Haojie come into view, he is a well-known presence in Galaxy Technology.

The bark of a tree, the name of a person, among the papers of Galaxy Technology, none of them are simple with the name of this big man on them.

Jiang Guoyu's eyes shone, and with the mood of pilgrimage, he quickly read it carefully as if it were a treasure.

What this paper says is that after mixing two gels in a certain ratio, they can quickly form a high-strength adhesive under specific infrared irradiation.

The more he looked at Jiang Guoyu, the more his eyes lit up. This hybrid gel not only has a wide range of applications, but also has high strength, high bonding and high sealing properties.

This is simply tailor-made for vacuum piping.

After all, it is the welding technology of spacecraft. If the strength and bonding sealing is not good, then the spacecraft will be welded and repaired.

Suo Chen, I have made a discovery. Jiang Guoyu quickly stood up and said.

Although there was no hope, Chen Wenfeng still wanted not to dampen the enthusiasm of young people and said with a smile: Well, Xiao Jiang, tell me.

Suo Chen, I found a paper by the chairman in the paper library, which contains a gel laser welding technology. Jiang Guoyu quickly struck while the iron was hot and said.

When he heard that it was Huang Haojie's paper, Chen Wenfeng immediately did not dare to look down upon it: What is the name of the paper?

It’s called ab gel laser welding technology. Jiang Guoyu quickly answered.

Chen Wenfeng and other researchers opened the holographic computer and started searching.

Soon everyone was studying the paper "AB Gel Laser Welding Technology" carefully.

After Chen Wenfeng read the paper, he asked Ma Sixing: Lao Ma, what do you think?

After all, it is Mr. Huang’s technology and there is no possibility of fraud. It is worth a try. Ma Sixing raised his glasses and replied.

Chen Wenfeng made a quick decision: Well, let's divide our forces into two groups. I'll go to the Materials Research Institute and ask them to make these two gels. Ma, you go to the Laser Research Institute to borrow a set of infrared lasers.

No problem, I'll go right away.

The two acted quickly. Since the paper contained a complete gel preparation method, the Institute of Materials quickly followed the example and prepared two gels.

When Chen Wenfeng returned to the Vacuum Pipeline Research Institute with two barrels of gel, Ma Sixing had already borrowed an infrared laser.

Are you experimenting now? Ma Sixing asked.

The materials and equipment are all ready, let’s experiment now. Chen Wenfeng rubbed his hands impatiently and said.

They quickly cleared a spare laboratory and aligned two sections of small vacuum pipes.

a gel is 3.47 kg, gel b is 4.84 kg.

Take out the appropriate weight of gel from the two barrels of gel, then mix them together and shake to stir.

Chen Wenfeng looked at the mixed gel in the blender, which had turned from white to blue, and said quickly:

It has changed color, so stop stirring.

A circle of tape has been affixed to the inside of the pipe joint in the experiment. Jiang Guoyu wore protective clothing and applied the mixed gel to the pipe joint.

Chen Suo, it has been painted.

Prepare for infrared laser irradiation. Chen Wenfeng ordered.

OK.

Drop! A correction red laser is irradiated on the mixed gel at the joint of the pipeline, and then the irradiation position and power frequency are adjusted.

An invisible infrared laser instantly illuminated the mixed gel at the joint of the pipe. Suddenly, the blue mixed gel began to change, and the opaque blue gradually turned into a translucent light blue.

About half an hour.

Seeing that the entire combined gel had turned translucent light blue, Chen Wenfeng immediately said: Stop the laser irradiation.

After the laser stopped, Ma Sixing asked: Do you want to test the sealing now?

Chen Wenfeng shook his head: Wait another ten minutes. Although the paper says that the welding will be completed when it turns translucent light blue, it is better to wait a little longer to be on the safe side.

Ten minutes later.

Now start testing the pipe tightness.

A group of researchers were eager to test the sealing performance of the pipeline. After a rigorous test, Chen Wenfeng and others were excited about the sealing performance of the pipeline.

Perfect.

The two pipes are like one whole.

Very good.

Now we can finally make a deal.
