Otaku Engineer in Great Tang Dynasty

"Master, this is a battery? Would you like to take a light bulb and try it?"

Workshop, in a laboratory.

When Fu Bo heard Li Zexuan say that the square thing in front of him was the first lead battery in the world, he was slightly surprised and couldn't help but say.

Li Zexuan nodded and said, "Of course I want to try! Fubo, I'm sorry to ask you to bring a light bulb with less power and some wires!"

The lead-acid battery does not need to be charged when it is just finished, it can be used directly because it is full of chemical energy. The so-called charging is to use external electrical energy to regenerate the internal active material (lead sulfate) and store the electrical energy as chemical energy. At this moment, the battery is not discharged, and there is no active material (lead sulfate) in the electrolyte, so there is no need to charge!

"Good! Master, wait a minute!"

Fubo smiled and left.

After a while, Fubo brought Song Xiaosi several bulbs of different sizes and some copper wires. Li Zexuan removed the rubber on both ends of the wires, and connected one end of the two wires to the positive pole of the battery. The other end was connected to the positive and negative screws at the end of the bulb, and the light suddenly turned on as soon as the wire hit the end of the light!

"It's bright! It's really bright! It seems that the power supply capacity of this lead battery should be more powerful than the voltaic battery you made earlier, because this kind of bulb voltaic battery can't light up at all!"

Upon seeing this, Fu Bo couldn't help but exclaimed.

In terms of electricity, he can be regarded as a half-knowledge. Although he is not as professional as Wang Ji, he understands the general meaning!

"Heh! Shanchang, your lead storage battery is really successful? Good deed, it can light up such a big light bulb. What is the output voltage of this lead storage battery?"

It was said that Cao Cao had arrived. After Wang Ji came out of the steel mill, he planned to come and have a look. He didn't expect to see this scene as soon as he stepped into the laboratory. He couldn't help but asked in surprise.

Compared to Fu Bo, his questions are obviously more professional!

Li Zexuan smiled and replied: "In this lead-acid battery, the voltage of a battery pack is about two volts. There are six battery packs connected in series. The voltage is about twelve volts, which is naturally higher than that of a voltaic battery! The continuous discharge capacity of this lead-acid battery is also much stronger than that of a voltaic battery. As for this small light bulb, it can be lit for twelve hours without any problem! And after the battery is used up, it can be charged and charged. Then it can continue to be used again!"

"Voltage twelve volts? Keep the light on for twelve hours? Can you charge after the battery runs out?"

Wang Ji was really shocked. He also used the voltaic battery made by Li Zexuan before. The power of each voltaic battery is only about one volt. The power is not long-lasting. If it is used to continuously send and receive telegrams, it is basically not. There will be no electricity in two hours!

The current batteries, both in terms of output voltage and long-lasting power supply capability, are far superior to voltaic batteries, and lead batteries can be recharged after they are exhausted, unlike voltaic batteries, which can only be thrown away after they are exhausted. Lost!

These incomparable and incredible advantages made Wang Ji a little doubtful of life!

"Shanchang, can you tell Wang about the principle of charging and discharging the lead-acid battery? This is the first time I heard that batteries can be recharged and recycled~!"

After a while, Wang Ji recovered from the shock, then looked at Li Zexuan expectantly and asked.

Although it is getting late, Li Zexuan knows that if he doesn’t explain the principle of lead-acid battery charging and discharging to Wang Ji clearly today, according to the old guy’s temperament, he probably won’t be able to sleep tonight. In order to let the old man sleep well, Li Zexuan took out a piece of blank rice paper, wrote the chemical equation on it with a pencil, and began to explain:

"Mr. Wang, the anode plate of this battery is made of lead dioxide, the cathode plate is made of lead, and the electrolyte is prepared dilute sulfuric acid. There is a separator in the electrolyte to separate the electrolyte between the two electrodes to prevent Electrode short circuit. When discharging, the lead of the cathode plate reacts with the electrolyte to generate lead sulfate and water, which releases electric energy; when charging, under the action of external electric energy, the lead sulfate reacts with the acid in the water to produce velvet lead and sulfuric acid , To store electrical energy..."

It took nearly a quarter of an hour to explain the charging and discharging principle of the battery to Wang Ji. During this period, Wang Ji asked many technical questions. Li Zexuan patiently answered them one by one. After everything was over, it was close to the time. !

"Shanchang, this lead battery is really amazing, especially now that the hydropower station and Yanhuang Academy in Lantian County are connected to electricity, the role of this battery is even more obvious! After the electricity is used up outside, it can be used again. The electricity generated by the hydropower station is perfect for charging! It's perfect! The old man really admires the mountain leader's whimsical ideas!"

Wang Ji's eyes were getting brighter, and his gaze toward the lead battery became more and more hot. At this moment, he suddenly remembered that he had come here to look for Li Zexuan but there was something serious, and he quickly said: "Oh! Shan Chang! Steelmaking! At the factory, vanadium steel has already been developed. The old man has done experiments in private. This vanadium steel is indeed much harder than ordinary steel. Would you like to check it out?"

Li Zexuan looked at the pitch black sky outside and couldn't help asking, "Bo Fu, what time is it now?"

After traveling for so long, Li Zexuan still has no accurate time and time judgment anytime and anywhere. He estimates that he will not be able to exercise this skill in his lifetime. He can only completely "control time" after inventing the watch later.

"Master, I should have just arrived at Haishi now!"

Fubo was silent for a moment and replied.

Haishi, which is nine o'clock in the evening!

He actually worked in the workshop from one or two in the afternoon until nine in the evening, and didn't even eat dinner in the middle!

Not only did he not eat dinner, neither did Fu Bo and Wang Ji!

"Don't watch! Don't watch! Watch again tomorrow! It's not early today, Mr. Wang and Fu Bo, these people are iron, and rice is steel. Let's go back to eat and rest early! The body is what we invent and create new things. capital!"

At this point in time, Wang Ji, a workaholic, even wanted to take him to "work" in a steelmaking plant. Li Zexuan would not do that if he killed him. He still has a wife and children at home, oh, there are no children yet, but It’s too late to go back and worry the wife, right? Therefore, he waved his hand and said to Wang Ji and Fu Bo.

"Hehe! What the young master said is that the old man should go one step ahead! I can't hold it at this age!"

Fu Bo said with a smile.

Wang Ji was unwilling, but seeing that Fu Bo had said so, he could not agree with him, so he had to clean up, and went out of the workshop with Li Zexuan, and went to Yunshan!

He now lives in the teachers’ dormitory of the academy, not the Yunshan Academy, because his title has not yet reached the level of professor!

However, judging from Wang Ji's research enthusiasm in chemistry and the recent results, it is probably only a matter of time before he is judged as a professor in a college!

"My husband, are you back? Haven't you eaten yet? I'll go and warm up the food for you!"

Back at the other yard, Han Yuxi heard the movement at the door and hurriedly greeted him from the house and said.

Obviously, she hadn't slept waiting for Li Zexuan to come back!

"Lady, why are you still up to sleep at this late hour? It's all because of your husband. I forgot the time when I was busy in the workshop, and I forgot to send someone to tell you!"

Li Zexuan said apologetically.

"Sang Gong, don't say that!"

Han Yuxi hurriedly said: "You are busy with major events in the workshop. Besides, when your child is not here, your concubine is not sleepy! Okay, let's not talk about it, I went to the Xianggong hot topic~!"

Li Zexuan embraced Han Yuxi, kissed him lightly on his forehead, and said, "The lady is so considerate, and it's a good thing to give her to her husband in a few days~!"

Han Yuxi curiously asked, "What good thing?"

Li Zexuan smiled mysteriously and said: "It's a secret for now, but it must be a big surprise!"

.........................

the next day.

After Li Zexuan had breakfast, he went to the workshop again.

It is said that he has now sat in the position of Guohou, and it is reasonable to not have to be so desperate. Even if he eats, drinks and has fun every day, relying on the huge foundation he set before, he can guarantee a lifetime of worry-free food and clothing!

Li Zexuan thought this way when he first crossed over. As long as he can be a master, he will eat and die for the rest of his life. But sometimes, only when you really sit in that position will you understand your responsibilities. !

Li Zexuan is now the head of the Yanhuang Academy, the real master of tens of thousands of people in Lantian County, and the helm of the entire "Yanhuang Group". There are countless students behind him who are learning from him and making progress; are there hundreds of people relying on him? Let him eat; there are countless craftsmen using his innovative technical tools to liberate productivity; and countless merchants are relying on him to get rich and realize their own value!

He can't stop!

He was a state leader who relied on engineering invention and creation, so he has the obligation to carry forward engineering in this era, and for him, creating some modern things in ancient times is also his pleasure. He thought, And he is willing to make this Tang with him more advanced and powerful!

When he arrived at the steel plant of the workshop, Wang Ji had already been waiting here. These two days were the weekends of the academy, so Lao Wang had no class in the academy and he could devote himself to "scientific research"!

"Shanchang, look! This is vanadium steel! This is the vanadium steel made according to the three different vanadium-doped ratios provided by you!"

Wang Ji pointed to the steel piled on the ground and said to Li Zexuan.

"Well! First use these vanadium steels to make swords and armors, and then try the effects!"

Li Zexuan nodded and said.

The proportion of vanadium in vanadium steel is generally not high, about 0.025%-0.059%. The hardness of vanadium steel produced by different proportions of vanadium is different. Which proportion is most suitable for swords and which is the most suitable. To make armor, you need to experiment!

In addition, adding a certain proportion of vanadium to steel can make rebar for the skeleton of reinforced concrete building components!

Compared with ordinary steel, rebar has very good solidity and toughness. It is suitable for use as a steel frame in large engineering projects. It can significantly improve engineering strength and seismic resistance!

"Okay! Wait a minute for the hill!"

Wang Ji nodded in response.

There are various craftsmen in the workshop, and naturally there is no shortage of skilled blacksmiths. Wang Ji sends these vanadium steels to the blacksmith’s workshop and instructs the blacksmith to use these three proportions of vanadium steel to build three sets of swords and armors. The blacksmith’s workshop Suddenly began to get busy!

"Shanchang, do you say that this sword made of vanadium steel can really be sharp and cut like mud? There is also armor. The armor made of vanadium steel will definitely be better than the armor used by my Datang soldiers. Is it strong?"

The temperature in the blacksmith's workshop was too high, and Wang Ji was too old, and he couldn't stand it up. After entrusting the craftsman, he left the workshop, found Li Zexuan, and asked.

Li Zexuan smiled slightly and nodded: "Although I dare not say that cutting iron is like mud, if it is an ordinary iron sword, if it encounters a sword forged by vanadium steel, it will definitely suffer a lot of damage! As for armor, I have more of this. Confident, the superiority of vanadium steel armor under the same conditions is absolutely beyond doubt!"

Vanadium alloying can greatly improve the strength of carbon steel, especially under the process conditions of quenching and tempering, the performance improvement is more obvious. In a previous life, an accident prompted the application of vanadium in automotive steel. It is said that Henry Ford I was watching a racing game when a French car was crashed. When inspecting the car wreck, he found that a crankshaft made in Sweden was damaged much less than expected.

After testing, it was found that the steel contained vanadium. So Ford used vanadium alloyed steel to make key parts of Ford cars to better resist road vibration and fatigue. He once said a famous saying: "If there is no vanadium, there will be no cars."

Because a very small amount of vanadium can make steel obtain excellent properties, people had a vivid evaluation of the role of vanadium in steel at that time-vanadium is a vitamin in steel.

It can be seen that the use of vanadium steel to make armor is not to say that it is absolutely invulnerable, but it can definitely resist most cold weapon damage!

"It's amazing. Who would have thought that just adding a little vanadium to the steel ~www.ltnovel.com~ can improve the performance of the steel so much, it is incredible!"

Wang Ji muttered to himself.

"Haha! Mr. Wang, please wait first, I'll go draw a drawing, I plan to make something new!"

Li Zexuan knew that building sword armor could not be completed in a short while, at least it would take a long time, so he said to Wang Ji.

When Wang Ji heard the words, his eyes lit up and said: "Oh? Shan Chang has a good idea again? I don't know what new things are going to be built this time?"

"Hehe! You'll know about Mr. Wang in a while! After the sword armor here is finished, remember to let someone come over and let me know!"

Li Zexuan didn't say clearly, he smiled for the teacher.

When Wang Ji saw this, it was not easy to follow up, he could only answer.

Li Zexuan returned to his office in the workshop and began to draw drawings. Song Xiaosi brought him food at noon. He finished eating three by one, and then continued to draw drawings. A thick pile of drawings has been piled up on the entire desk, so it can be seen that what he is going to build this time is not simple!

"Shanchang, the sword and armor are ready! Take a look!"

Around Shenshi, Wang Ji brought two workshop servants, and brought three pairs of swords and armors to Li Zexuan's office, and said excitedly.

"Oh~? How effective is it? Has Mr. Wang ever tried it?"

Li Zexuan put down the pen, stood up, and asked with a smile.

"I tried it! I tried it! This sword is really as the mountain leader said, ordinary iron swords can be easily cut by it! It is too sharp! As for this armor, bows and arrows can not be shot, and it is simply not strong. Stronger!"

Wang Ji said ecstatically.
