Otaku Engineer in Great Tang Dynasty Chapter 1418: Mr. Xiao Ke, big wedding!
"Master, why are you here~?"
In the Qiqu Pavilion workshop, Fubo saw Li Zexuan and hurriedly greeted him.
Li Zexuan stopped, but his eyes scanned in the courtyard, while watching, he replied:
"Fu Bo, I heard that the vanadium ore from the Shu area had been shipped back, so I came to have a look! Where are they? How many are there?"
Fubo smiled and said: "Master, the ore has been transported to the steel mill. The old man knows that the master value this ore, but he dare not pile it up!"
Li Zexuan smiled, just as he was about to speak, another person came in from the workshop.
"The vanadium mine is here, where is it... Shanchang, are you here too?"
The person here is Wang Ji.
Vanadium is a necessary catalyst for large-scale mass production of concentrated sulfuric acid. Not only Li Zexuan is concerned, but Wang Ji has been waiting for the vanadium mine in Shuzhong to be shipped back quickly.
Li Zexuan smiled and nodded, and said: "Yeah! Mr. Wang, are you very fast?"
Wang Jile said: "Hey! As the head of the chemistry department, of course, the old man has the responsibility to help the academy develop new chemical materials. This old man of vanadium ore has been looking forward to it for a long time!"
"Master, the guards who transported the mines this time were all Qiang people from the Shu area. They also brought two letters saying that they were handed to you by Mr. Ke!"
At this moment, Fu Bo took out two painted letters from his arms, handed them to Li Zexuan, and said.
"Mr. Xiao Ke?"
Hearing this name, Li Zexuan was a little dazed subconsciously. After a moment, he recovered and couldn't help but happily said: "It should be Ke Shiqing, right? Ouch, it seems that this young man is in the Qiang tribe. It’s a good mix inside~! They are all honored as Mr.!"
Wang Ji stroked his beard and smiled proudly: "Our students at Yanhuang Academy will become stars and moons wherever they go. The old man Ke Shiqing has some impressions. He is indeed a good, diligent and studious boy~! "
This old guy looks like this, just like some modern old gentlemen. When he learned that his students are promising, he was very contented, but his mouth and face were still quite reserved and restrained. Looking like a fart, Li Zexuan couldn't help but want to laugh.
"Hehe! Let's go! Mr. Wang, let's take a look at the fineness of this batch of vanadium ore?"
Li Zexuan saw that Fu Bo was secretly facing Wang Ji who was "smelly fart" and hurriedly pulled Wang Ji toward the steel plant.
"Oh~! With so many ores, can you extract a lot of vanadium?"
Walking into the yard of the steelmaking plant, I saw a large pile of light gray ores piled under a canopy. At a glance, it can be thousands of catties to say nothing. Wang Ji's eyes widened. , Could not help but exclaimed.
Li Zexuan walked to the front, picked out a piece from the ore pile at random, brought it to the front, carefully examined it for a moment, and smiled:
"Well! The color is very good! Mr. Wang, this pile of vanadium-titanium magnetite can produce at least 300 catties of vanadium. This amount of vanadium is enough to meet the consumption of sulfuric acid in the workshop! Recently you are old Work harder, let the craftsmen in the workshop rebuild the boiler, build a small-scale vanadium smelting workshop, and then build a sulphuric acid workshop to produce a batch of concentrated sulphuric acid as soon as possible. I have great use!"
Wang Ji responded excitedly: "Yes! The mountain is long!"
Even if Li Zexuan didn't say anything, he would take the initiative to ask for it. After all, he finally got so much vanadium-titanium magnetite. If he couldn't refine it by himself, he would grow hairy in his heart!
"Oh! That's right! Shan Chang, the "Chemistry" textbook says that this sulfuric acid is highly corrosive and can react with iron to form copper sulfate and hydrogen. Then what should we use to store concentrated sulfuric acid in the future?" /
Wang Ji paused for a moment, then said suddenly.
Li Zexuan thought for a while, smiled and replied: "Mr. Wang, dilute sulfuric acid can dissolve iron and release hydrogen. The reaction principle is that freely moving hydrogen ions in dilute sulfuric acid react with iron. But concentrated sulfuric acid is in contact with iron. , But will not or rarely react.
Because of the high purity of concentrated sulfuric acid, sulfuric acid exists as a covalent compound instead of an ionic compound. When the purity is high, it ionizes very few hydrogen ions, almost none, so it will not corrode ironware , On the contrary, a passivation reaction occurs with iron, so that a dense oxide film is formed on the surface of iron. This oxide film is very dense and prevents the concentrated sulfuric acid from entering the iron to continue the reaction.
However, although concentrated sulfuric acid can be stored in carbon steel, it is best to store it under normal temperature and pressure, so that the corrosion rate of carbon steel is the lowest, because hot concentrated sulfuric acid will also react with iron. To ensure the safety of concentrated sulfuric acid storage, horizontal storage tanks should be selected, and leak-proof walls should be built around the storage tanks.
Pyrotechnics must be strictly prohibited in the storage room of sulfuric acid, because a small amount of dilute acid on the surface of the concentrated sulfuric acid liquid will react with iron to produce hydrogen. Hydrogen will explode when it meets fire. In terms of safety, Mr. Wang, you must be cautious and then cautious, safe production , More important than Mount Tai! I don't want any safety incidents in our workshop! "
At the end, Li Zexuan's face must be solemn.
Even in modern times, chemical plants are the most prone to safety accidents. Either toxic chemical products leak or explosions caused by flammable substances. No matter which one is, it will cause damage to the surrounding people. Great damage!
It is precisely because of this that Li Zexuan has so solemnly told Wang Ji again and again!
Wang Ji also understands the stakes. He solemnly said: “The chief of the mountain can rest assured that the old man will put safety first, and regularly train the craftsmen in production safety, and compare their monthly wages with In this way, everyone will strictly abide by the regulations of safe production!"
Li Zexuan's eyes lit up and he nodded and said, "Well! Mr. Wang, you have a good idea. When you come back, you will discuss with Fu Bo how to implement this wage system as soon as possible. Craftsmen who comply with the regulations will pay more money and violate safety. All the craftsmen in the workshop should pay attention to it!"
"The long mountain, no problem! The old man knows the importance!"
Wang Ji nodded and responded.
……………………………
After instructing Wang Ji to pay attention to safe production, Li Zexuan asked Wang Ji to produce a batch of concentrated sulfuric acid as soon as possible, because he was going to be a battery!
In addition, vanadium, a catalyst used in the production of sulfuric acid, can also be used as a catalyst for cracking petroleum in the future. It can be described as one thing with multiple uses and two birds with one stone!
Leaving the workshop and returning to the other hospital, Li Zexuan took out the letter that Uncle Fu gave him. On the envelope, one reads "Shan Chang's kiss" and the other says "Mother's kiss", Li Zexuan Opening the letter Ke Shiqing had written to him, he began to read it carefully.
"It has been nearly a month since I left Yunshan. Shiqing misses the people and things in the academy very much, but Shiqing is even more grateful to Shanchang for the opportunity to benefit the people of his hometown this time. The road to Shudi is being built;
The imperial court also sent a large number of officials with a lot of money to support the people's livelihood construction in Shu;
A group of merchants from Chang'an City also opened shops in Chengdu Prefecture. They brought many new things that local people had never seen before. The commerce in Shuzhong is booming;
The mining of vanadium-titanium magnetite has allowed the local Qiang people to work in the mine to earn money, but within half a month, each miner’s wages are almost equal to the previous three or four months. Income!
Following your instructions from the head of the mountain, Shiqing abides by the principle of safety first, preferring to mine the vanadium mine more slowly, but also to ensure the safety of the miners, so no one has been injured or killed since the vein mining!
Oh, by the way, "Datang Daily" has also opened an office in Shuzhong. Now the people in Shuzhong are getting used to reading newspapers every morning! Students saw in the newspaper yesterday that Shan Chang had invented a new type of waterwheel and made the drawings public. Shi Qing was proud of being a student of Shan Chang!
In addition, His Royal Highness Shu asked to set up a branch of Yanhuang Bank in Shuzhong. With the help of Gao Changshi, the people and merchants in Shuzhong have slowly begun to accept the new currency of Tang Yuan. , The number of people using copper coins is getting fewer and fewer!
With the help of the Sanbao brothers, the students brought Quyuanli, "Datang Dictionary", bicycles, coal stoves, and honeycomb coals to the middle of Shu. With the support of Gao Changshi, they opened up the minds of the people. , Promote agriculture, promote business!
Today's Shuzhong is undergoing earth-shaking changes. How fortunate for the students to witness the growing prosperity of their hometown and the richer lives of the villagers! The student once remembered that Shan Chang said before: “It’s so simple on paper, and you must do it yourself.” The students realized the true meaning of this sentence in the process of leading the people in their hometown to get rich!
Some things seem simple, but when you really do it, you often encounter a lot of difficulties. Fortunately, those students who are in difficulty have heard it. Now the students have become Mr. Xiao Ke in the eyes of the people of Zhangzhou!
The mountain leader can rest assured that the students will not be arrogant or discouraged when they win. Haosheng will lead the people in Shu to get rich, and will never shame the mountain leader or discredit Yanhuang Academy!
Student Ke Shiqing pays respects and wishes Shan Chang everything goes well and healthy! "
"Msang, what are you looking at? So happy?"
Li Zexuan had just finished reading the letter, and was about to sigh, when Han Yuxi happened to come over and asked with a soft smile.
"Haha! It's nothing! It's a letter from a college student to my husband!"
Li Zexuan smiled, pulled his wife to his side, and smiled.
"Student letters? Aren't all the students of Xiang Gong in the college? Why do I need to write to you?"
Han Yuxi frowned the pretty Liu Ye eyebrows and said in doubt.
Li Zexuan smiled and asked: "The lady still remember the student named Ke Shiqing who invited Ying to go to Shuzhong?"
Han Yuxi condensed her eyebrows for a while, and then said: "Oh! Concubine body remembered. Earlier, his mother came to Yunshan to send you a letter to Xianggong!"
"Well! It's him! This kid is doing good work in the middle of Shu. He is the teacher of his husband, and I am very pleased to see it~!"
Li Zexuan handed the letter to Han Yuxi, and then smiled.
"That's it! Why is my father-in-law smiling so happy!"
Han Yuxi took the letter paper and swept it aside, and said with joy: "Xiangong is benefiting the people of Lantian County, but Ke Shiqing is benefiting the people of his hometown. This student is very much like you! If there are talents from Yanhuang Academy, if the students of the college are all Like Ke Shiqing, he can use what he has learned to benefit one party. At that time, Xiang Gong can truly be full of peaches and plums, and his fame will endure forever~!"
Li Zexuan heard this, his heart inevitably stirred, he patted his wife on the shoulder, and sighed: "So, Yanhuang Academy is Datang, our family's greatest wealth and reliance! Instead of delving into the art of intrigue and fighting Yu Chaotang, it’s better to start school and build a government, teach what you have learned to thousands of disciples. He will treat me all over the world. Even if you are the prime minister and emperor, you should respect me three points!"
These words are the truth in his heart!
At the beginning, Yanhuang Academy and Communication Engineering were founded to benefit the people all over the world and to seek a little welfare for the working people of this era. At the same time, Li Zexuan founded Yanhuang Academy to seek a support for himself, one who can be in this feudal society. In the age of emperors, settle down, settle down, and let others dare not easily move their own reliance!
Only when the students of Yanhuang Academy become more and more promising, and when there are more and more promising students, his reliance will become more and more reliable!
The reason why Sage Kong is so shining and famous is that in addition to his own greatness, it is also that his three thousand disciples spread his doctrine and sent it to the altar in one fell swoop!
Li Zexuan knew that he couldn't be a saint like Confucius~IndoMTL.com~ He just wanted to get a solid foundation in this feudal era, nothing more!
"My husband, for this family, you have worked hard~!"
Han Yuxi stroked Li Zexuan's forehead with some distress, then leaned on the latter's shoulder and said softly.
"Hehe! I am not bitter for my husband! I know my wife in this life, and I love and protect my parents like this, not for my husband!"
Li Zexuan stroked Han Yuxi's long hair and comforted him softly. After a while, he said, "Oh! Shiqing wrote a letter to his mother, and sent the letter to her husband. Chang'an, lady, you also pack up, we will return to Lantian County in a while!"
"Hmm~! Oh, by the way, Xiang Gong, we don’t seem to be able to go back today!"
Han Yuxi nodded first, then shook his head, and said.
Li Zexuan suddenly wondered: "Why is this? Does the lady have anything to do in Yunshan?"
Han Yuxi saw that Li Zexuan really couldn't remember what was going on, so she had no choice but to say, "Did you forget about Pang Feiji? Tomorrow will be Pang Feiji's wedding. Pang Feiji has followed Xianggong all the way. He will get married tomorrow, should he go there if he is fair and reasonable?"
Li Zexuan opened his mouth, and it suddenly dawned on him that Liu Feng had mentioned this to him before, but he had too many things in his daily life, and he forgot about it accidentally. At this time, he smiled embarrassedly:" That's right! Hey! Look at the memory of being a husband, I almost forgot about it! Thanks to the lady for your reminder! Then we won't go back to the county town tonight, and we will have a wedding tomorrow together~!"
"Hmm!"
Han Yuxi smiled sweetly and nodded in response.
