"Faubert, don't ask first. You'll know in the future! That thing in the back was just a plaything for people to amuse themselves with! The things at the front are more useful, but it's hard to tell now. We need to build something to carry it! The most important thing now is to build the crusher and the high temperature steam generator! "
Li Zexuan saw Faubert's confused expression and knew what he was thinking. He quickly explained.
"Okay! This old man will arrange it now! These two machines aren't complicated. I'm sure they can be completed within three days! "
Faubert nodded and didn't continue asking.
"Oh, right! Faubert! "
Li Zexuan patted his head and suddenly shouted, "When you melt the rubber in the high temperature steam generator, you can add a certain proportion of sulfur. As for how much to add, Faubert, you have to send someone to do an experiment! As far as I know, adding a different proportion of sulfur into the rubber will affect the hardness and wear resistance of the final rubber! The two things I want to make require a certain degree of hardness and wear resistance. Faubert, if you can't make up your mind, you can show me all the vulcanized rubber obtained from the experiment. I'll choose the most suitable one! "
The rubber extracted from raw rubber latex was called raw rubber. Raw rubber was a kind of linear polymer that was relatively soft and easily melted under heat. After adding sulfur, the rubber could be vulcanized under high temperature. A portion of the carbon-carbon double bonds in the raw rubber would open and form a disulfide bond with the sulfur. This caused the originally linear rubber to transform into a reticulated polymer structure. The vulcanized rubber would also have better physical properties.
Raw rubber would crack under heat. Its mechanical properties were poor, its wear resistance was weak, and its texture was soft. After vulcanization, due to the cross-linking between the molecules, the melting point and strength of the vulcanized rubber would increase. Vulcanization of rubber was an indispensable step in the modern rubber manufacturing process. Vulcanized rubber was used in many industrial products, such as tires!
Faubert didn't ask where Li Zexuan got all this information from, because he knew it would be a waste of time. His young master seemed to have been born with knowledge. He had too many secrets!
"Young master, will all the rubber in the future be processed like this?"
Faubert asked worriedly after pondering for a while.
Li Zexuan thought for a moment and replied, "Most of them should be dealt with this way. What's wrong?"
Except for a few industrial rubber products that did not need to be vulcanized, most of them needed to be vulcanized.
Faubert smiled bitterly and said, "Young Master, in this way, I'm afraid we'll need a lot of sulfur! Where are we going to buy so many? "This time, in order to refine the rubber latex, we have almost emptied all the vinegar shops in Chang 'an City. As a result, the price of vinegar has increased. If we continue to buy sulfur like this, I'm afraid that the price of sulfur in all the medicine shops in Chang' an City will also increase! If that's the case, then we've committed a sin! "
In ancient times, sulfur was mainly used for medicinal purposes. The sulfur that Li Zexuan had used to make explosives to blow up the Snake Spirit Mountain was bought from a pharmacy! Sulfur was first used for medicinal purposes in "Shennong's Materia Medica". In this book, sulfur was used as a traditional Chinese medicine. It was listed as the third medicine in the medium-grade medicine, and it could cure more than ten diseases.
Faubert was afraid that the large-scale purchase of sulfur by the workshop would cause the price of sulfur to increase. After all, the sulfur in the medicine shops was used to treat diseases. How could they prepare so much in stock? If the patients who needed sulfur for treatment could not afford it, it would be a sin!
After listening to Faubert's words, Li Zexuan could not help but feel a little strange. He never thought that refining rubber would cause the price of vinegar in Chang 'an City. Of course, he also did not expect that the necessary industrial raw material for the practical use of rubber, sulfur, would be so difficult to obtain!
"Then let's produce it on a small scale first! Anyway, the two rubber products that I drew for you, Faubert, are not in a hurry to be mass-produced! Faubert, do you have any trustworthy people who are willing to work hard? "
At this moment, Li Zexuan realized that even if he had a bellyful of good ideas, without resources, he would still have to give up! The "Don't Touch Me" carriage from before had not been mass-produced until now. Why? It was not because the workshop lacked manpower or technology, but because they lacked iron! Also, the horseshoes that he made before had not been promoted to the imperial court because of the lack of iron!
According to historical records, during the Zhenguan period, the annual steel production of the Tang Dynasty was only a few hundred tons. That's right, it was just a few hundred tons!
What could a few hundred tons of steel do? It would probably be difficult to arm an army of ten thousand people!
Therefore, steel was an extremely important strategic resource for the country. Most of it flowed to the imperial court, and only a small portion was left to the common people. Therefore, no matter how advanced Li Zexuan's workshop was, and no matter how high the production efficiency was, it was impossible to produce a few hundred to a thousand "Don't Touch Me" carriages in a month!
In the end, it was because he did not have a mine!
Li Zexuan thought helplessly.
"Young master, what are you planning to do?"
Faubert asked with a strange expression.
"Look for ores, mine ores!"
Li Zexuan said fiercely.
In his previous life, he was a poor loser. In this life, he was a rich second generation. He wanted to be a mine owner. As the saying goes, with a mine at home, one's heart would not panic! That was the logic!
"Look for ores ~?"
Faubert muttered, and then asked, "Young master, the world is so big, where should we look for ores? Even the most hardworking people would not be able to bear it! "
Li Zexuan's expression had returned to normal. He smiled and said, "This is not a big problem. I know the specific locations of a few ores. We just need to send people to look around there!"
He had just recalled the geography books in his previous life. He knew that there were a few large pyrite ores in the Shanxi area. The so-called pyrite ores were mainly the sulfide of iron. When the time came, he would find a way to refine it. Not only would he be able to obtain iron, but he would also be able to obtain sulfur. Wouldn't that be killing two birds with one stone?
Faubert's heart shook again. He thought that his young master really knew everything. He seriously thought about it, and his face revealed a rare embarrassed expression. He said, "Young master wants to find someone to help find ores. This old man would like to recommend someone!"
"Oh? Faubert, quickly say it! "
Faubert coughed twice and said,
"Cough cough! Young master, this old man has a nephew called Fubin. His parents passed away early, and this old man raised him. This child … Although he is usually a little playful, as long as it is a serious matter, he will definitely treat it seriously! Young master, if … "
"Haha! That's fine! Tomorrow afternoon, Faubert, bring that kid to Yunshan to find me. I will also tell him the general location of these ores! "
Without waiting for Faubert to finish, Li Zexuan directly interrupted with a smile.
Faubert said in surprise, "Young master, you, this …"
"No need to say more. Faubert, I still trust the person recommended by you! Oh, right, Faubert, if you have a way to directly buy the sulfur ores in other people's hands, as long as the price is not too outrageous, just tell me. I will buy it! "
