Otaku Engineer in Great Tang Dynasty

"Uncle Fu, don’t ask first, you will naturally know in the future! The things in the back are nothing but playthings for entertainment and entertainment! The things in the front will be more useful, but it’s hard to tell now. You need to carry his Only things can be made! The top priority at the moment is that you first have to make this shredder and high-temperature steam generator!"

When Li Zexuan saw Fu Bo's look confused, he knew what he was thinking, and quickly explained. z z z z z z z z z z z

"Okay! Old man, let's make arrangements! These two machines are not complicated, and they can be done in three days!"

Fubo nodded, and did not continue to question.

"Oh, yes! Fubo!"

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. For the specific amount, you have to send someone to do an experiment! As far as I know, Adding different proportions of sulfur to the rubber will affect the hardness and wear resistance of the final rubber! The two things I want to do need a certain degree of hardness and wear resistance. If you are not sure about it, Forber, You can show me all the vulcanized rubbers obtained from the experiment and I will choose the most suitable one!"

The rubber obtained from the raw rubber latex is called raw rubber. The raw rubber is a relatively soft and easy-to-melt linear polymer. After vulcanization, the rubber can be vulcanized at a high temperature, making part of the carbon in the raw rubber. The carbon double bond is opened to sulfur to form a disulfide bond, which converts the originally 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, with poor mechanical properties, weak wear resistance and softness. The vulcanized rubber has an increased melting point and increased strength due to the cross-linking of 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 did not ask Li Zexuan where he got the information, because he knew it was for nothing if he asked, his young master seemed to be born with him, and he had too many secrets in him!

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

After considering it for a while, Fu Bo asked with some worry.

Li Zexuan thought for a while and said, "Most of them should be handled like this. What's wrong?"

Except for the rubber in a few industrial products that do not require vulcanization, most of them require vulcanization.

Fu Bo smiled bitterly: "Master, in this case, I am afraid that a lot of sulfur will be needed! Where can we buy so much? This time, in order to refine rubber latex, we are about to empty the vinegar workshop in Chang'an City. The price of vinegar has risen now. If you buy sulfur in this way, I am afraid that the sulfur in the major drug stores in Chang'an City will also increase in price! Then we will do evil!"

In ancient times, the most important function of sulfur was medicinal use. Li Zexuan used the sulfur to make explosives to explode Snake Lingshan from a drug store! Sulfur is used for medicinal purposes and was first seen in Shennong's Materia Medica. In this book, sulfur is used as a traditional Chinese medicine and is listed as the third Chinese medicine, which can cure more than ten kinds of diseases.

Fu Bo is afraid that the large-scale acquisition of the workshop will cause the price of sulfur to rise. After all, the sulfur in the drugstore is for curing diseases. Where will there be so much inventory? When the time comes, patients who need to buy sulfur for treatment cannot afford it, so they are really committing evil!

Li Zexuan couldn’t help feeling a little weird after listening to Fubo’s words. He never expected that the extraction of rubber would cause Changan vinegar to be expensive. Of course, he did not expect that rubber would be necessary for practical application. Sulfur, an industrial raw material, is so difficult to deal with!

"Then let's make small-scale production first! Anyway, the two rubber products I painted for you are not in a hurry for mass production! Forber, do you have anyone who can be trusted and willing to bear hardships?"

Li Zexuan realized at this time that even if he had a good idea, he still had to stop cooking without the 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 lack of iron!

According to historical records, the annual steel output of Datang during the Zhenguan period was only a few hundred tons, which is just a few hundred tons, if you heard me wrong!

What can hundreds of tons of steel do? An army of 10,000 people is estimated to be choking!

Therefore, steel at this time is an extremely important national strategic material. Most of it went to the court, and only a small part went to the private sector. So even if Li Zexuan’s workshop technology is advanced and the production efficiency is high, it is impossible to say Build hundreds of "Don't Touch Me" carriages in a month!

After all, there is no mine at home!

Li Zexuan thought helplessly.

"Master, what are you going to do?"

Fu Bo asked with a strange look.

"Looking for ore, mining!"

Li Zexuan said viciously.

In the previous life, he was a poor man. In this life, he is a rich second generation. He wants to be a mine owner, just because there is a mine at home, so he doesn't panic! That's the truth!

"Exploring?"

Fu Bo murmured, and then asked: "Master, where the earth is going to look for? No matter how hard it is, you can't hold it!"

Li Zexuan's complexion has returned to normal, he smiled slightly and said, "This is not a big problem. I know the specific locations of several mines. Just send someone to find them nearby!"

He just recalled the geography of his previous life and knew that there are several relatively large pyrites around Shanxi~www.ltnovel.com~ The so-called pyrites are mainly iron sulfides. Then he will find ways to extract them. Can you get iron and sulfur, won’t you kill two birds with one stone?

Fu Bo's heart was shocked again. The secret path that his young master really knows everything, he thought about it seriously, a rare embarrassed expression appeared on his face, and said: "The young master wants to find someone to help mine, but the old man thinks Recommend one person!"

"Oh? Forber, say it!"

Uncle Fu coughed dryly and said:

"Ahem! Master, the old man has a nephew who is called Fubin. His father and mother passed away early and was raised by the old man. Although this child is usually a bit playful, he will definitely take it seriously as long as it is business. If the young master is"

"Haha! That's fine! Tomorrow afternoon, Uncle Fu, you bring that kid to Yunshan to find me. I will 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 surprised: "Master, you, this"

"Needless to say, I can still trust the person you recommended! Oh, yes, if you have a way to buy sulphur ore directly from others, as long as the price is not too outrageous, you can tell me. I will buy it!"
