The old things I repaired have become fine

Chapter 234: Flying to the Shipwreck Museum again? Will there be any problem this time? (6 rewards plus )

I will repair this old thing I got myself, even if it means crying.

After all, you can't beat him to death.

Shen Le really started to repair it while crying. As usual, he first went through the instruments, scanning electron microscope, energy spectrometer, X-ray fluorescence diffraction, X-ray fluorescence, one round after another.

The conclusion is that this strip of material is probably a steel knife that has been buried in the soil for a long time. The wooden scabbard and handle have been saturated with water and corroded, leaving only the residual shape;

The blade was in better condition, retaining its shape. However, it was also severely corroded, and had a high salt content.

Scanning electron microscopy shows that there are different degrees of salt deposition on the surface of the blade;

The X-ray fluorescence spectrometer, which had a huge head and was several times larger than a hair dryer, showed that chloride ions existed on the surface and inside of the blade;
The content is quite high, so high that if it is not dealt with and left there as it is, the entire ironware will definitely be corroded by rust!

Then, Shen Le took an X-ray of this unidentified object and laughed. Although it was covered with various corals, shells, and gravel, nothing could escape the X-ray:

That huge Y-shaped shadow looks so familiar!
Girl, you found your slingshot!
Shen Le rolled up his sleeves and began to clean the dirt. He practiced dozens of times on the sea-salvaged porcelain and ironware that Lao You had brought. At least, he was confident in cleaning the outermost attachments:

He used small pliers, tweezers, a scalpel and various tools to scrape and pry off the corals, shells and other things one by one.

First, clean the outer layer aggressively, then clean the inner layer carefully.

Finally, the slingshot, which has a small layer of sand on the outside and whose shape can be basically seen, is placed into the ultrasonic instrument for final surface cleaning.

The slingshot is not too rusty, the base is still there, of course, the belt on it is gone. The problem is, the knife...

Shen Le looked at the blade on the tray in front of him, at a loss. If it was rusted to the same degree as a small oil lamp, its base was still there, and the rust on the outside was removed, it would still be a shiny good oil lamp;

But this broken knife...

If he used the same drastic method he used on the small oil lamp, after removing all the rust, the knife… would probably be gone too!

He majored in ancient architecture! He is really not good at ironware!

When they deal with rusted ironware, they usually remove the rust if possible. If not, they will replace it with an iron nail, iron pillar, etc. The purpose is to ensure the safety and stability of the building.

If you really want to rust it to the point of being completely brittle, while retaining its complete shape, this is the responsibility of teachers who specialize in repairing ironware, and they won’t even let their students do it.

If you are not careful, the iron piece will be broken!
Shen Le had accumulated some experience in the shipwreck museum when he was repairing the compass last time. He remembered that wooden objects needed to be dehydrated and fixed, and iron objects needed to be rust-proofed, desalinated, corrosion-retarded, and sealed.

As far as I can remember, there is a very unreasonable method for wood dehydration called supercritical CO2 fluid drying technology, which can achieve dehydration, desalination and desulfurization at the same time;
What about ironware? Is there any quick way to fix it?

The methods Shen Le learned from books, whether it was the aqueous solution method, alkaline sulfite reduction method, alkali solution cleaning method, electrolytic reduction method or plasma reduction method, were not very suitable!
Either it takes too long, requiring soaking for half a year, or it can only be used when it is just unearthed, or it is easy to damage the iron base.

Shen Le knows himself very well. I think the old master can handle it well, but for a newbie like him, just forget it.

Shen Le took out his cell phone and quickly swiped through the contact list, preparing to call his doctoral senior at the Shipwreck Museum.

It's better not to bother two people with one thing. You should probably ask him to help dry the wooden handle and sheath of the steel knife. It's better to ask him about the ironware as well.

What if, he meant what if, there is a reliable way in the shipwreck museum that can quickly get rid of this piece of iron?

As he was swiping, he suddenly lost his concentration and pressed a contact. In a moment, the big man who made the silver-gilded flower ornaments by opening his mouth wide to swallow food last time appeared on the screen with his chubby face:

"Mr. Shen? What can I do for you? Any business to introduce?"

"what……"

Shen Le couldn't say "Sorry, I called the wrong number." This big guy's ability and connections are both worth maintaining.

He smiled and greeted her while thinking quickly, trying to think of a reliable reason to call:
"It's like this. I just remembered that you like to eat various rare metals, right? Rhodium, palladium, osmium, iridium..."

"Yes, yes, yes!" The Alloy Boss's face quickly began to glow, and his curly hair was faintly metallic in color.
"Do you have connections?"

"I don't have any connections, but I have ideas." Shen Le tried to maintain a smile:
"That is, I wonder if you would accept eating alloys? Or ones with more impurities?

If you accept, you can contact the Special Affairs Bureau, and get those old gold pen nibs, old circuit boards, etc...." "Hey!" The Alloy Boss waved his hand vigorously, his face suddenly dimmed, and the metallic color of his hair also faded:
"I thought it was a good idea. It's useless. Those things are recycled by special organizations. After a round of tossing, they come out as precious metals again. It's not my turn."

There really are no fools in this world. Picking up bargains also requires strength, it's not that easy to pick up. Shen Le maintained a smile and listened to him:
"By the way, do you have any gold, silver, copper or iron items that need repairing? You can come to me. I'm especially good at metal items!"

"Thank you so much! I'll definitely look for you if I need anything!"

Shen Le answered loudly with a smile on his face, and secretly made up his mind not to look for him - at least, this slingshot and blade would never look for him.

The way the boss swallows the metal into his stomach and then spits it out, who knows whether the ingredients of the spitted out object are still original?
Of course, even if you don't want to find it, you still have to thank it. In order to express his gratitude, Shen Le racked his brains and came up with another suggestion:
“By the way, if you are more interested in lithium metal, would you consider scrapped lithium batteries?
Although the content is high, it is relatively rare in nature and is usually not easy to eat! Moreover, it is rich in energy! "

Alloy Boss's eyes lit up. With a "click", the screen on the other side went black and the signal disappeared.

Shen Le was startled. He called "Hello" to the screen several times but got no response. He shook his head and went to call his doctoral senior.

The doctor listened to his inquiry enthusiastically and answered confidently:

"Iron desalination? You've asked the right person! We have two desalination studies here, one using wood and the other using iron! The iron desalination study will be published soon!
The equipment is complete. Bring the stuff here and I'll find someone who specializes in iron desalination and have him calculate the parameters for you!"

Shen Le curiously asked for details. The doctoral student calmly said:
"It's similar to what we do with wood desalination. Wood uses supercritical carbon dioxide, and iron uses subcritical water treatment. Wait a minute, I'll get the paper for you.

You can only read it yourself, don't publish it to anyone!"

Shen Le nodded naturally. They were all researchers, and no one could stand the possibility of their papers being leaked before they were published.

It was because he was familiar with everyone in the shipwreck museum that he was able to receive such treatment. Otherwise, if he was allowed to fly to the museum to take a look and was not allowed to take pictures, they would have treated him as one of their own!
He only waited half an hour before a few screenshots were sent to him. Shen Le quickly read the main part of the paper and sighed:

He must visit this shipwreck museum again.

That subcritical water treatment equipment was designed and customized by the laboratory itself. It is not something that can be bought on the market!

It’s not even something you can borrow from any museum or research institute!

According to the description in the paper, apart from the Clemson University Cultural Relics Conservation Center in the United States, the only shipwreck museum in China is doing this. He went back to his alma mater and couldn't borrow this thing...

By the way, that equipment is a pressure vessel. The design and manufacture of any pressure vessel requires special qualifications. It is not something that anyone can weld with just a blueprint...

"Then Senior Brother, when can I come over? I have a few things that need repairing..."

He asked respectfully:

"We have wood and iron. When the time comes, I will ask my senior brother for guidance on the process parameters - the price is negotiable!"

In a few words, he and his doctoral senior brother decided on the time to come. Of course, he had to have a name, and he needed the Special Affairs Bureau to help him issue a letter;

Money must be given, too. Even if the Shipwreck Museum doesn't make money from Shen Le, it can't put money into it, and the hard work of several brothers can't be saved;
But this is much better than carrying a pig's head and not being able to find the temple gate!

Shen Le excitedly agreed on a time to come with his senior brother, and even packaged up all the values he measured on the instrument and sent them to his senior brother so that he could start calculating.

After putting down the phone, they started packing up their things, especially fixing the wooden sheath, wooden handle and iron sheet to prevent them from deformation and damage on the road.

While cleaning up, I had to explain to Hong Jiayi:
"It's not that I want to abandon you, it's your two friends. Only by going there can we get the best equipment and fix it the fastest...

You also want them to be repaired soon, right? These are the weapons used by your friend and your master. You all recognize them, right? "

The red wedding dress fluttered gently and the dagger whistled clangingly, but fortunately no one raised any objection.

Shen Le breathed a sigh of relief, picked up his phone and started booking tickets. Before he could press "Confirm Payment", his phone rang again:
"Mr. Shen!" The Alloy Boss's fat face was shining brightly, almost overflowing:

"Your idea is great! I just crushed my phone, took out the battery and tasted it, it's really delicious!!!"
