Chapter 303
"But now we don't have any solution, we can't delay the whole project, right?" Ma Sixing said helplessly.

"There is nothing to worry about. The bridge was originally planned to be completed in May 2020. There is still eleven months to go. We don't need to take risks." Chen Wenfeng still rejected the thermal expansion and contraction sleeve proposal.

"OK then!"

"Old Ma, your plan is still good, you continue to improve it as a backup just in case."

"I will continue to follow up on this plan."

The two hurriedly ate breakfast, and both continued to study how to solve the sealing problem of the junction.

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

But the high-vacuum vacuum pipeline is not good at all, even a small air hole may cause disastrous consequences.

In addition, the bonding between the welded metal and the graphene composite FRP material is not good, so the welding scheme is out.

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

"The strength of foam cement is enough, but you will not forget the congenital defects of foam cement, right?" Ma Sixing obviously did not approve of this proposal.

What is the congenital defect of foam cement, that is, the sealing performance of foam cement is not good. When it is used as a wall, it needs to be coated with special anti-seepage material to avoid water leakage.

What's more, for vacuum pipes that require such a high degree of vacuum, as for the use of ordinary concrete, it is better to use Ma Sixing's thermal expansion and contraction sleeve 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, speak out what you have in mind, stones from other mountains can make jade."

All the researchers are racking their brains and contemplating hard. Some are looking through the materials in the online library, some are looking in the internal journal paper library, and some are 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 all of them are doing odd jobs, Yinhe Technology did not exploit these interns, and the salaries and benefits they should have are all available.

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

If you perform well during the internship, it is not impossible to become a regular in advance.

So Jiang Guoyu cherishes the opportunity to intern at the Vacuum Pipeline Research Institute very much.

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

Suddenly he saw a paper "AB Gel Laser Welding Technology" that was uploaded this morning. At first, Jiang Guoyu didn't pay attention to it. After all, in Yinhe Technology's internal journals, there are hundreds if not thousands of such papers.

But soon he was not calm, because he saw the author of the paper.

The word Huang Haojie came into view, and it is a thunderous existence in Galaxy Technology
The bark of a tree, the name of a person, among the papers of Yinhe Technology, none of the papers with the name of this big man is simple.

Jiang Guoyu's eyes were shining brightly, and with a pilgrimage, he hurriedly studied it carefully as if it were a treasure.

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

The more you look at Jiang Guoyu's eyes, the brighter it is. This hybrid gel not only has a very wide range of applications, but also has high strength, high bonding, and high sealing.

This is literally tailor-made for vacuum pipes.

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

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

Although he didn't report any hope, Chen Wenfeng still kept the idea of ​​not dampening the enthusiasm of young people, and said with a smile: "Oh? Tell me about it, Xiao Jiang."

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

As soon as he heard that it was Huang Haojie's paper, Chen Wenfeng didn't dare to underestimate it: "What's the name of the paper?"

"It's called AB gel laser welding technology." Jiang Guoyu replied quickly.

Chen Wenfeng and other researchers turned on the holographic computer to search.

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

After Chen Wenfeng finished reading the thesis, he asked Ma Sixing beside him, "Old Ma, what do you think?"

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

Chen Wenfeng made a decisive decision: "Well, we will divide into two groups. I will go to the Materials Research Institute and ask them to make these two gels. Ma, you can 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 suit and prepared two gels.

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

"Do you want to experiment 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 emptied a spare lab, aligning two smaller sections of vacuum lines.

"A gel is 3.47 kg, and B gel is 4.84 kg."

From the two buckets of gel, take the appropriate weight of gel, then mix together and shake.

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

"It has changed color, so stop stirring."

A circle of adhesive tape has been pasted on the inside of the pipe joint in the experiment. Jiang Guoyu, wearing protective clothing, applied the mixed gel on the pipe joint.

"Chen Suo, it's already painted."

"Prepare for infrared laser irradiation." Chen Wenfeng ordered.

"Ok."

drop!A corrective 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 was irradiated on the mixed gel at the junction of the pipes in an instant, and the blue mixed gel began to change suddenly, and the opaque blue gradually turned into a translucent light blue.

About half an hour.

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

After the laser stopped, Ma Sixing asked, "Do you want to test the airtightness now?"

Chen Wenfeng shook his head: "Wait another 10 minutes. Although the paper says that the welding will be completed when it turns translucent light blue, it's better to wait to be safe."

10 minutes later.

"Now start testing the pipe tightness."

A group of researchers eagerly began to test the airtightness of the pipeline. After a rigorous test, the airtightness of the pipeline made Chen Wenfeng and others very excited.

"Perfect."

"The two pipelines are like a whole."

"Great."

"Now it's finally time to do business."
