The emergence of rubber tires has received high attention from Zhao Zhen. He immediately issued an order to study and research on rubber in the Academy of Fisheries. Fortunately, the three departments have allocated funds, otherwise Zhao Zhen would have to go with Bao Zheng to bathe buns again...

After being heated, the biggest problem of natural rubber is that it will deform after being heated and friction. This is an extremely difficult problem, and it will harden when the weather is cold, reducing the shock absorption effect.

The craftsmen of the Gewu Academy were very troubled by this. On one hand, there were a large number of orders and on the other hand, there were inevitable flaws. For this reason, Zhao Zhen did not hesitate to offer a huge reward. Whoever could solve this problem would be rewarded with a huge reward of 10,000 yuan!

Not to mention the craftsmen of the Gewu Academy, even for ordinary merchants, this 1000-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-month-

Zhao Xiaowu, the young Investigator who once invented the steam locomotive, was once again favored by the goddess of luck. By chance, he told the official to experiment with the method of making lead white.

In a mud tank containing dilute acetic acid solution, place the spiral lead sheets rolled up above the solution, and cover the mouth of the tank with lead plates. Place the jar on horse manure in the hut and stack it on a rack supported by layers of wooden boards.

In fact, Zhao Zhen had already known the principle of making lead white. There was a certain amount of lead white in the palace... The fermentation of horse manure released heat to evaporate the acetic acid. The acetic acid reacted with lead to form alkaline lead acetate, which was then carbonated by carbon dioxide to form white alkaline lead carbonate. After more than a month, most of the lead was converted into lead white. Take out the lead white, mix it with water and grind it into a paste. Finally, you only need to wash away the soluble lead acetate, and then dry it to obtain the lead white.

Out of blind trust in the government, Zhao Xiaowu added this substance called lead white to the rubber, and also added sulfur... So a rubber that will not melt or deform even if exposed to the sun is produced.

All the final contributions were counted on Zhao Xiaowu, but only he knew that this was due to his admiration for the official family and the helplessness of treating the dead horse as a living horse, which had long since become the rubber at present.

In fact, before him, someone had already added sulfur to the rubber, but the effect was not as good as Zhao Xiaowu. If Zhao Xiaowu had not discovered that adding lead whiteness made the rubber vulcanized more thoroughly, he would not have received the reward of tens of thousands of yuan.

In the end, he used the millions of rewards in the Geju Academy. Money was nothing to him. The steam engine had already earned him a lot of rewards. The official family received rewards every now and then. With his own official salary, the entire family could support people. What would it take to make so much money?

He also became a clear stream among the officials of the Juwu Court. Su Shi, the head of the Juwu Academy who had just been transferred to the charge of the Juwu Court, praised him very much. Although he knew that this was actually arranged by the official, and although he already knew that the official had already made vulcanized rubber in the palace, he still praised Zhao Xiaowu's character without hesitation.

Now Su Shi is fully responsible for investigating things. His role is very simple, adjusting and leading the rhythm between investigating things and the court, managing investigating things, and adjusting the problems between them and court officials.

The Gewu Academy has now become the largest yamen in the Song Dynasty. It is not only a small R&D institution, but also a Wisdom Palace in Beijing has also been included in the Gewu Academy. There are so many subjects, absorbed and recruited, and there are so many types of craftsmen in the past!

They were the force of rapid development and advancement of the Song Dynasty. The train provided an amazing speed for the Song Dynasty. This speed was incomparable to anything. After so many years of development, the technology of neat trains has become quite mature.

The principle of the steam engine is there. As long as you study it carefully, one day you can study it thoroughly. Now the trains of the Song Dynasty not only appear in the four capitals, but the power of merchants and capital is powerful.

Some merchants saw the benefits, so they spent money to buy trains from the Gewu Academy and paved railways, intending to operate them themselves. Even Zhao Zhen had to admire their business acumen. This was actually monopolizing transportation!

Which industry is the most profitable? Of course it is a monopoly industry!

The Gewu Academy and the court officials regarded the train as a national weapon, and how could they accept the business of merchants? But Zhao Zhen did not think so. The railway laying in the Song Dynasty was very slow, not because it could not be afforded, but because it was quite troublesome like building the Great Wall.

If it weren't for the importance of the Great Wall to the Song Dynasty, I'm afraid even the court officials wouldn't have supported it.

Since the Great Wall can also be outsourced to merchants, why can't the railway construction be built? So Zhao Zhen issued an order to give merchants new opportunities again, and the court provides trains, while the merchants pave the railways themselves. When the final operation was carried out, the two sides divided the money into each other!

Even though the court took a big advantage, these merchants still flocked to them!

Is the reason too much? I have a joint business with the court and got the court's documents. This is the official business! Not only does it mean that the money is divided into five or five points, the people must believe it, are they still worried that there will be no customers?

The most important thing is that my status has also been improved. This is something I can’t buy even if I spend money. When I go out, I can say that I am a person who does things for the court......

The dense railway network was laid in the Song Dynasty, and the benefits of these railways were suddenly revealed from scratch. The officials in the court suddenly realized that these railways were the important part of developing national strength.

The transport of grain from the south to the north was originally by canal transportation, and sometimes by sea transportation, but with the train, how much grain can the seven or eight carriages carry? It was transported to the north day and night, and it was originally a month or even more, but now it can be reached within six or seven days!

What a terrifying and amazing transportation capacity. If the demand is high, the south can even send more trains to meet the demand. It can be said that since the train was established, the court has truly been able to control the food price!

In the territory of the Song Dynasty, almost all places can produce grain. In the year of famine, the price of grain will soar. However, with the train, once a place is affected, the food from the court will arrive as quickly as possible to solve this problem!

This made many people clearly see that the days of making money by selling grain by natural disasters have long passed, and it is best to make money by relying on factories.

Invisibly, the problem of land annexation was resolved. While the Song Dynasty's speed solved this problem, it also provided great help to the construction of the Great Wall.

Thanks to the increase in trains and railways, these transportation routes that appeared on the land of the Song Dynasty like a major artery, have never been cut off, and a large amount of stone and cement are transported to the edge of the Great Wall every day.

Building the Great Wall is not very difficult, because of the subcontracting system of merchants, they only need to build the place they choose. While building the Great Wall, they also built a cement road along the Great Wall on the side of the Song Dynasty. This not only facilitates the construction of the Great Wall, but also a route for the Great Song Dynasty to transport troops and march in the future.
