"Uncle Fu, don't ask now. You will know later! The things in the back are just toys for entertainment! The things in the front will be more useful, but it is difficult to see now. The thing that carries him needs to be removed. You have to build something! The most urgent task right now is that you must first build this crusher and the high-temperature steam generator!"
Seeing Uncle Fu's confused look, Li Zexuan knew what he was thinking and quickly explained.
"Okay! I'll make the arrangements right now! These two machines are not complicated. I think they can be made within three days!"
Fu Bo nodded and did not continue to ask further questions.
"Oh, by the way! Fu Bo!"
Li Zexuan patted his head and suddenly shouted: "When you melt the rubber in the high-temperature steam generator later, you can add a certain amount of sulfur. How much should you add? Uncle Fu, you have to send someone to do an experiment! As far as I know, Adding different proportions 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. If you are not sure at that time, Fubo, You can show me all the vulcanized rubbers obtained through experiments, and I will choose the most suitable one!"
The rubber extracted from raw rubber latex is called raw rubber. Raw rubber is a linear polymer that is relatively soft and easy to melt when heated. After adding vulcanization, the rubber can be vulcanized at high temperatures, so that part of the carbon in the raw rubber The carbon double bond opens with sulfur to form a disulfide bond, which converts the original linear rubber into a polymer compound with a network molecular structure, and the vulcanized rubber has better physical properties.
Raw rubber will crack when heated, has poor mechanical properties, weak wear resistance and soft texture. Due to the cross-linking between molecules, the vulcanized rubber has an increased melting point and increased strength. Rubber vulcanization is indispensable in the modern rubber production process. step. The rubber in many industrial products is vulcanized rubber, such as tires!
Uncle Fu didn't ask where Li Zexuan knew this information, because he knew that asking would be in vain. His young master seemed to know it from birth, and he had too many secrets!
"Master, will all rubber be treated like this in the future?"
After Fu Bo thought about it for a long time, he asked worriedly.
Li Zexuan thought for a while and replied: "Most people should handle it this way. What's wrong?"
Except for a few rubbers in industrial products that do not need to be vulcanized, most of them do.
Uncle Fu smiled bitterly and said: "Master, this will require a lot of sulfur! Where can we buy so much? In order to refine rubber latex this time, we almost emptied the vinegar factory in Chang'an City. The price of vinegar has increased now. If we continue to buy sulfur like this, the price of sulfur in major drug stores in Chang'an City will also increase! Then we are committing a sin!"
In ancient times, the main function of sulfur was medicinal. The sulfur used by Li Zexuan when he made explosives to blow up Sheling Mountain was bought from a drug store! The medicinal use of sulfur was first seen in "Shen Nong's Materia Medica". In this book, sulfur is used as a traditional Chinese medicine and is listed as the third among traditional Chinese medicines and can cure more than ten diseases.
Uncle Fu was afraid that the workshop's large-scale acquisitions would cause the price of sulfur to rise. After all, the sulfur in drug stores was used to treat diseases. How could they prepare so much inventory? When the patients who need to buy sulfur for treatment cannot afford it, they are really committing a sin!
After listening to what Uncle Fu said, Li Zexuan couldn't help but feel a little strange in his heart. He never expected that refining rubber would cause Chang'an to be jealous. Of course, he didn't expect that rubber would need to be put into practical use. Industrial raw material - sulfur, is so difficult to deal with!
"Then let's start with small-scale production! Anyway, the two rubber products I drew for you, Uncle Fu, are not in a hurry to be mass-produced! Uncle Fu, do you have anyone you can trust who is willing to endure hardships and stand hard work?"
Only then did Li Zexuan realize that even if he had a lot of good ideas, he would still have to stop working if he didn't have the resources! The previous "Don't Touch Me" carriage has not been mass-produced until now. Why? It's not because the workshop lacks manpower, nor because of lack of technology, but because of lack of iron!
According to historical records, the annual steel output of the Tang Dynasty during the Zhenguan period was only a few hundred tons. You heard me right, just a few hundred tons!
What can you do with hundreds of tons of steel? Arming an army of 10,000 people is probably enough!
Therefore, steel at this time was an extremely important national strategic material. Most of it went to the court, and only a small part was lost among the people. Therefore, no matter how advanced the technology of Li Zexuan's workshop was and how high the production efficiency was, it was impossible to say that Build hundreds or even thousands of "Don't Touch Me" carriages a month!
After all, there is still no mine at home!
Li Zexuan thought helplessly.
"Master, what are you going to do?"
Fu Bo asked with a strange look on his face.
"Look for ore, dig for ore!"
Li Zexuan said somewhat viciously.
In his previous life, he was a poor man. In this life, he is a rich second generation. He wants to be a mine owner. As the saying goes, if his family has a mine, he will not panic! That’s the truth!
"Looking for minerals~?"
Uncle Fu murmured, and then asked: "Master, the world is so big, where should we go to look for minerals? Even the most hard-working people can't bear it!"
Li Zexuan's expression returned to normal. He smiled slightly and said, "This is not a big problem. I know the specific locations of several mines. I just need to send people to look for them nearby!"
He just recalled the geography book in his previous life and knew that there are several relatively large pyrites in Shanxi. The so-called pyrites are mainly iron sulfides. When the time comes, he will find a way to refine them to obtain both iron and iron. If you can get sulfur, wouldn't it kill two birds with one stone?
Uncle Fu's heart was shocked again, and he secretly thought that his young master really knew everything. He thought about it seriously, and with a rare expression of embarrassment on his face, he said, "Young master wants to find someone to help find mines, but I would like to Recommend someone!”
"Oh? Uncle Fu, please tell me!"
Uncle Fu coughed twice and said:
"Ahem! Master, I have a nephew, called Fu Bin. His parents died early, and I raised him single-handedly. This child... although he is usually a bit playful, as long as it is serious business, he will definitely take it seriously. Yes! If the young master..."
"Haha! That's okay! Uncle Fu, please bring that kid to Yunshan to meet me tomorrow afternoon, and I'll tell him the general locations of these mines by the way!"
Before Uncle Fu could finish speaking, Li Zexuan interrupted with a smile.
Uncle Fu was shocked: "Master, you, this..."
"Needless to say, I still trust the person you recommended, Uncle Forbes! Oh, by the way, Uncle Forbes, if you have a way to directly purchase sulfur ore from others, as long as the price is not outrageous, just tell me. I'll buy it!"
