After ten days, Jiang Yuan opened the system panel again.
'Directed evolution of technology' is still in the cooling, and we need to wait for another 20 days.
Jiang Yuan opened the technology of 'low manganese steel foaming agent'.
"Low manganese steel blowing agent: a chemical used to make manganese steel foam.
Manganese steel foam, fast solidification speed, high hardness, good tensile strength and toughness, easy molding, strong corrosion resistance, density of only 0.2g/cm^3, basically equivalent to plastic foam ......"
Then here are three or four pages of instructions for manufacturing blowing agents for low-manganese steel.
About 7 steps detailing every detail of this blowing agent.
Jiang Yuan quickly browsed and found that before manufacturing the foaming agent, it was necessary to manufacture a batch of low-manganese steel to prepare test materials for subsequent experiments, which would use the unique rapid solidification vacuum induction furnace of the metallurgical laboratory of Qianwan University.
Jiang Yuan instructed Cheng Qianqian: "I had an idea and wanted to make something.
You first help me refine a batch of low-manganese steel, with a manganese content of 2.6% and 10 kilograms. ” Cheng Qianqian immediately acted excitedly, she usually has no chance to use the rapid solidification vacuum induction furnace, the service life of this instrument is only about 10,000 times, and the cost is about 5,000 yuan each time, which is simply burning money.
When he first entered the laboratory, Jin Lifeng asked Cheng Qianqian to try it twice, but he didn't let him touch it later.
Now I have the opportunity to practice!
And Jiang Yuan wants 10 kilograms, but this stove is one kilogram, which means that she can use it at least ten times.
Cheng Qianqian looked at Jiang Tao with a longing expression.
The deputy director of the laboratory has been sick in bed for a long time, and the director is not there, Jiang Tao is the person in charge of the laboratory, in charge of the use and distribution of experimental equipment. "10 kilograms is a bit much......
Jiang Tao originally wanted to habitually bargain, hoping to reduce 10 kilograms to 3 kilograms, but thinking of the mentor's instructions before leaving, he was looked at by Cheng Qianqian's beautiful eyes, and his mouth was not angry: "Okay."
Wu Feng immediately gathered around Cheng Qianqian, offered his private collection of Mai Lisu, and said with a calm face: "Cheng Meinu, give me a chance to practice my mobile phone!"
Only then did everyone react and immediately surrounded them, and the beauties and sisters kept screaming.
Jiang Yuan looked at everyone, and he didn't have the urge to do it himself.
If it weren't for the fact that it was not good to explain the source of the foaming agent formula, he would have wanted to directly throw this formula to Jin Lifeng and let him do it for himself.
You must know that experimental abilities are piled up by a large number of failures, and Jiang Yuan does not have a 'master of experimental learning' skill to help him quickly improve his experimental ability.
Now that he has learned some chemical knowledge, Jiang Yuan can also understand the principle of foaming agent, and he has a reason to explain the source of the foaming agent formula, so he has no desire to do it.
Although Jiang Yuan is far from the ability to invent a low-manganese steel blowing agent, it is much easier to understand than to invent, isn't it?
Jiang Yuan was very sure that if someone questioned his professional ability now, he would be able to use his professional knowledge to fool him in an instant.
Looking at the scrambling scientific dogs, Jiang Yuan smiled slightly.
Just let me be a quiet mouthpiece king!
At about two o'clock in the afternoon, Jiang Yuan got 10 kilograms of laboratory-grade high-purity low-manganese steel, and ground it into fine steel grit.
Manganese steel has a very strange and interesting temper: if 2.5-3.5% manganese is added to the steel, the resulting low-manganese steel is simply brittle like glass and will crumble when struck.
However, if more than 13% manganese is added to make high-manganese steel, it becomes both hard and tough.
Jiang Yuan asked for 2.6% low-manganese steel, which was easily ground into fine sand in a special tool in the laboratory.
Under Jiang Yuan's command, the low-manganese steel grit was divided into 100-gram bottles, for a total of 100 bottles. 100 bottles can always make a qualified blowing agent, right?
Jiang Yuan was not sure, and commanded Cheng Qianqian to say: "Next, we started to build a new reagent, which I call low manganese steel blowing agent.
In my imagination, it can expand low-manganese steel grit to dozens of times, and at the same time it is as tough as a piece of iron.
First ......"
Cheng Qianqian, under the command of Jiang Yuan, began to do experiments, while the others secretly pouted.
You're a genius, we admit it, but invention isn't easy.
No matter how fast you learn, it's useless, and many times inventing this thing is simply about looking at the face.
Dog poop arrived, and test tubes that weren't wiped clean could have produced a great invention.
If you don't believe it, you don't wash your hands and understand the saccharin invented.
Even more disgusting was penicillin, which was caused by the scientist's snot falling into a petri dish...... ...... ......
The first experiment was a logical failure.
The foaming agent made by Cheng Qianqian is a light red watery liquid, which is not at all as described by the system: "Low manganese steel blowing agent, colorless and odorless viscous liquid ......"
Even so, Jiang Yuan still asked Cheng Qianqian to test it with the reaction of low manganese steel sand.
Otherwise, do you say, "The foaming agent I imagined is a colorless, odorless, viscous liquid"?
Can't explain it at all, okay?

How do you know the characteristics of the reagent without manufacturing?
Since the density of low manganese steel is about 8 times that of water, and the density of water is about 5 times that of manganese steel foam.
In other words, when the low-manganese steel reacts with the blowing agent to become manganese steel foam, the volume must expand by at least 40 times.
And Jiang Yuan didn't know whether this process would produce toxic gases, and the system didn't say anything.
Therefore, the amount of low manganese steel powder must be controlled, and the reactor carrying the manganese steel foam must also be sealed and large enough, otherwise it may explode.
After instructing Cheng Qianqian in the details, the specific operation was naturally done by her, and Jiang Yuan quietly became a king with his hands on his back.
The experiment failed.
Reagent No. 1 poured into low-manganese steel grit did not produce any reaction, as if water was poured into sand.
"Oh, failed."
The crowd of onlookers dispersed, and their hearts were inexplicably relaxed.
Fortunately, chemical inventions are still face-dependent, and we still have a chance!
If we still look at our brains, we should just go and be gardeners.
Cheng Qianqian stuck out her tongue and said embarrassedly: "I remember, the third step just now seems to be a bit of a mistake."
Jiang Yuan smiled: "Then we'll do it again."
Reagent No. 2 failed.
Cheng Qianqian thought about it and said hesitantly: "The timing of the invention of chemical reagents is very unstable, and it is basically a matter of luck.
Generally speaking, half a year doesn't necessarily get any results, you only rent for a month, I'm afraid I'm ......"
She stopped in the middle of speaking.
Jiang Yuan smiled calmly: "Wasting time?
Rest assured, I'm sure. ” Seeing that he was resolute, Cheng Qianqian could only nod and say: "Okay, since you insist, I have the money to take anyway~" 3.
Good reagents fail. ......
Reagent 12 failed.
The experiment lasted until 10 p.m., and as expected, it didn't work out once.
Cheng Qianqian began to waver, and said with a blank face: "Is it that my level is not good, why don't I find a chemistry teacher tomorrow?"
The low-manganese steel foaming agent seems to have written down all the steps, but Cheng Qianqian is just an ordinary graduate student, and her experimental ability is too poor, and Jiang Yuan estimates that other teachers are also like that.
Everyone usually repeats foreign experiments, and then brushes up papers, who can really make breakthroughs and innovations?
There are not too many cases of failure caused by the failure of this kind of experimenter, Jiang Yuan has experienced it in high school, and the radios assembled by other students can be used, as long as he doesn't make a sound!
Therefore, don't look at Jiang Yuan's words, Jiang Yuan didn't dare to speak at all in the experiment.
Jiang Yuan could only continue to encourage: "I'm sure the recipe is fine, and we'll start on time tomorrow at half past eight and continue testing.
Let's go, I'll send you back. ” Now, I can only hope that tomorrow's 'Xueba Moment' will find something.
"Well, okay, I'll definitely work harder!"
Cheng Qianqian saw that he was resolute and was willing to continue the experiment.
She usually doesn't have this kind of treatment to do experiments, so she just took the opportunity to practice more.
