"Uncle Fu, don't ask, you will naturally know later! The thing in the back is just a plaything for people's entertainment! The thing in the front will be more useful, but it is hard to see now, and it is necessary to put the Things need to be built! The most urgent task right now is to build this crusher and high-temperature steam generator first!"

Seeing Uncle Fu's confused look, Li Zexuan knew what he was thinking, and quickly explained.

"Okay! The old man will arrange it now! These two machines are not complicated, and they will be ready within three days!"

Fu Bo nodded and did not continue to ask.

"Oh, yes! Faber!"

Li Zexuan patted his head and suddenly exclaimed: "When you melt the rubber in the high-temperature steam generator later, you can add a certain percentage of sulfur, and how much to add, Fu Bo, 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 do need a certain hardness and wear resistance. You can show me all the vulcanized rubbers obtained in the experiment, and I will choose the most suitable one!"

The rubber extracted from the raw rubber latex is called raw rubber. The raw rubber is a kind of straight-chain polymer that is relatively soft and easy to melt when heated. After vulcanization, the rubber can be vulcanized at high temperature. The double bond opens and sulfur forms a disulfide bond, so that the original straight-chain rubber is converted into a polymer compound with a network molecular structure, and the vulcanized rubber has better physical properties.

The raw rubber will crack when heated, with poor mechanical properties, weak wear resistance and soft quality. The vulcanized rubber has an increased melting point and increased strength due to the cross-linking between molecules. 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 Li Zexuan where he got the information, because he knew that it would be a vain question, and his young master seemed to know it from birth, and he had too many secrets!

"Master, will all rubbers be treated like this in the future?"

After thinking for a while, Fu Bo asked worriedly.

Li Zexuan thought for a while and replied, "Most of them should handle it this way, what's wrong?"

Except for very few rubbers in industrial products that do not require vulcanization, most of them require vulcanization.

Uncle Fu said with a wry smile: "Young master, I'm afraid I'll need a lot of sulfur! Where can we buy so much? This time, in order to refine rubber latex, we've almost emptied the vinegar workshop in Chang'an City. Now that the price of vinegar has gone up, if you buy sulfur like this again, I am afraid that the price of sulfur in the major pharmacies in Chang'an City will also increase! Then we will make a sin!"

In ancient times, the most important role of sulfur was medicinal. The sulfur used by Li Zexuan when he made explosives to detonate Snake Spirit Mountain was bought from a drugstore! Sulfur is used for medicinal purposes. It was first seen in "Shen Nong's Herbal Classic". In this book, sulfur is used as a kind of traditional Chinese medicine. It is listed as the third Chinese medicine and can cure more than ten kinds of diseases.

Fubo was afraid that the gluttonous purchase of the workshop would cause the price of sulphur to rise. After all, the sulphur in the pharmacy was for the purpose of curing diseases. Where would they prepare so much inventory? At that time, patients who need to buy sulfur to treat their illnesses can't afford it. It's really a sin!

After listening to Fu Bo's words, Li Zexuan couldn't help but feel a little weird in his heart. He never thought that refining rubber would cause Chang'an vinegar to be expensive. Of course, he didn't even think that rubber was put into practical application. The industrial raw material - sulfur, is so difficult to deal with!

"Then let's start small-scale production! Anyway, I'm not in a hurry to mass-produce the two rubber products I drew for you! Fubo, do you have any trustworthy people who are willing to bear hardships and stand hard work?"

Only at this time did Li Zexuan realize that even if he had a bevy of good ideas, he still had to stop without resources! The previous "don't touch me" carriage has not been mass-produced until now, why? Not because of lack of manpower in the workshop, nor because of lack of technology, but because of lack of iron! Also, the horseshoes he got before were not promoted to the imperial court, and there is also a factor of iron deficiency in it!

According to historical records, the annual steel output of Datang during the Zhenguan period was only 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, at this time, steel was an extremely important national strategic material. Most of it went to the imperial court, and only a small part went to the people. Therefore, no matter how advanced Li Zexuan's workshop technology and production efficiency were, it was impossible to say Build hundreds of thousands of "don't touch me" carriages a month!

After all, there are no mines at home!

Li Zexuan thought helplessly.

"Master, what are you going to do?"

Faber asked with a strange look on his face.

"Looking for ore, mining!"

Li Zexuan said a little viciously.

In his previous life, he was a poor man, but in this life he is a rich second-generation. He wants to be a mine owner. As the saying goes, there is a mine at home, so don't panic! That's it!

"Looking for mines~?"

Uncle Fu murmured, and then asked, "Master, the world is so big today, where should I go to look for mines? Even a person who can endure hardship can't bear it!"

Li Zexuan's complexion has returned to normal. He smiled slightly: "This is not a big problem. I know the specific locations of several mines. Just send someone to look for them nearby!"

He just recalled the geography book of his previous life and knew that there were several comparisons in Shanxi.

The big pyrite, the so-called pyrite, is mainly the sulfide of iron. When the time comes to find a way to refine it, you can get both iron and sulfur. Isn’t it killing two birds with one stone?

Uncle Fu was shocked again, secretly thinking that his young master really knows everything, he thought about it seriously, a rare expression of embarrassment appeared on his face, and said: "Young master wants to find someone to help find mines, but this old man wants to Recommend someone!"

"Oh? Uncle Fu, hurry up!"

Fu Bo coughed twice and said:

"Cough cough! Young master, this old man has a nephew named Fu Bin. His parents died early, and he was raised by the old man. This child... Although he is usually a little playful, as long as it is serious business, he will definitely take it seriously. Yes! If the young master..."

"Haha! That's fine! Tomorrow afternoon, Uncle Fu, bring that kid to Yunshan to find me, and I'll tell him the general location of these mines by the way!"

Before Fu Bo finished speaking, Li Zexuan interrupted with a smile.

Uncle Fu was shocked: "Master, you, this..."

"Needless to say, I can still trust the person you recommend, Uncle Fu! Oh, yes, Uncle Fu, if you have the means to buy the sulfur ore from others directly, as long as the price is not outrageous, just tell me, I'm going to buy it!"
