Chapter 818

Immediately into June, Qingzhou has been a little hot, bright sunshine baking cement road, some steamed people.

Xiao Ming returned to the palace for lunch and waited for Lu Tong in the imperial library.

In the afternoon, when the pendulum clock pointed to two o'clock, Lu Tong arrived outside the imperial study on time, accompanied by a 30-year-old youth.

The young man was dressed in a long white dress of Qingzhou University, with a lot of familiar things in his arms.

"See your majesty."

After entering the imperial study, Lu Tong salutes Xiao Ming.

After getting up, Lu Tong introduced to Xiao Ming: "emperor, this is a student of Qingzhou University. His name is Liu Chuanzhi. "

" Liu Chuanzhi? Nice name. "Xiao Ming said with a smile.

"Thank you for your praise." Liu Chuanzhi was a little shivering and obviously nervous.

Xiao Ming has a smile in his eyes. These people who are dedicated to scientific research do not deal with outsiders for a long time, so their characteristics are similar.

He said, "you don't have to be nervous. I'm not a man eating tiger. Are these rubber products you made? "

at this time, Liu Chuanzhi remembered the rubber in his arms and said," yes Yes, Emperor. According to the information provided by the emperor, CaoMing has successfully mastered the method of vulcanizing rubber. With the metal mold provided by the equipment department, CaoMing has now produced a number of rubber products. "

Xiao Ming nodded. The rubber sent by the Dutch can only be called raw rubber, which is sticky and easy to break, so it can't be used in industry.

The vulcanized rubber is called mature rubber. This kind of rubber does not have the problem of raw rubber. It has high elasticity, heat resistance, tensile strength, and will not dissolve in organic solvents. Modern rubber products are basically vulcanized rubber.

Looking into Liu Chuanzhi's arms, Xiao Ming's smile is more and more intense. In fact, it's not very difficult to shape rubber, because rubber will become fluid at high temperature, which is similar to molten steel.

Molten steel can be molded with iron mold, and the rubber can also be molded with iron mold, which is also the way to mold Xiao Ming.

The only thing to do is vulcanize the rubber before molding.

This kind of vulcanization needs to use a substance as the crosslinking agent, which is sulfur. According to the time and temperature, different quality vulcanized rubber can be produced. There are many vulcanization methods, and the simplest one is to mix the two and heat them directly.

"Emperor, this is the tire, this is the hose, this is the piston "Liu Chuanzhi took out all the products he brought.

Xiao Ming took it from him one by one and looked it over and over again before putting it down.

For him, rubber is a crucial link in the development of industry, sole, warm water bag and elastic band used in daily life.

Rubber is indispensable for gloves used in medical treatment, blood transfusion tubes and various tires used in transportation, conveyor belts used in industry, drainage and irrigation rubber tubes used in agriculture, sealing equipment used in scientific experiments, airplanes, tanks and artillery used in military.

The reason why the west can pull the east far away in science and technology is that it controls rubber to a large extent. Unfortunately, like today, rubber in this era is still controlled by Europe.

Although he got some rubber tree seeds from Holland, it took him a long time to go from seed to tree.

Of course, he has another solution, which is rubber grass. But according to the data, the origin of rubber grass is in contemporary Yili, Xinjiang. In this era, rubber grass is obviously still under the control of barbarians.

Only when he drives out the barbarians can he plant rubber grass in this area, but it seems to be a difficult problem to build this place and keep it.

So, for him, the most appropriate way at the moment is to buy Rubber from Europeans.

As for the occupation of South America, he still needs a long way to go. Even if he has a fleet of armored ships now, it also needs a fixed port to provide fresh water and coal from Dayu to South America. Otherwise, his fleet will be paralyzed on the way before it reaches America.

"Great, great." Facing one rubber product after another, Xiao Ming is unavoidably excited. With rubber, many machines can be realized.

He believes that the most important problem to be solved is the traffic problem.

The most profound experience of this era for Xiao Ming is that if he wants to be rich, he should build roads first. Only when the transportation is convenient, can the exchange of various resources be rapid.

Lu Tong and Liu Chuanzhi look at Xiao Ming excitedly and look at each other with a thick smile on their faces.

Xiao Ming put down the medical blood transfusion tube and other rubber products and said, "what reward do you want? "

" emperor, it's just a matter of lifting a finger. It depends on the information provided by the emperor, and I dare not ask for a reward. "Lu Tong said with a smile.

Xiao Ming ignored him and said, "you don't want it, and Liu Chuanzhi doesn't want it either? "

Lu Tong scratched his head and began to laugh, while Liu Chuanzhi was embarrassed and opened his mouth. In the end, he didn't say anything.

Seeing this, Xiao Ming said, "Liu Chuanzhi, in the future, you will be given the rubber of the state of Dayu. Now you are welcome. In this way, in order to enable you to concentrate on the production of rubber, I will reward you with a thousand taels of silver and give you another 50 Mu farm. How about that?""Thank you, Emperor long en!" Liu Chuanzhi's body trembled with excitement.

Before that, he was just a poor scholar. The reason why he entered Qingzhou University was that his family had no money left for him to go to Beijing to take the exam. However, this decision brought him another chance.

Xiao Ming raised Liu Chuanzhi, who bowed himself to thank him for his kindness. He said, "I'm not a miser. As long as you can do things in a down-to-earth way and make contributions to the state of Dayu, your titles, land and money are not a problem. Now my army has seized a large area of land outside the pass. You don't have to worry that I have no land to reward. "

Liu Chuanzhi nodded deeply.

After asking them some questions about rubber, Xiao Ming asks them to go back for a while.

When they left, he immediately sat down and picked up the pen.

Now this pen can only be stained with ink while writing. Now with rubber, he can finally have a pen that can absorb water. After this, he is going to recommend the pen to all officials of the state of Dayu, so as to save the time of writing brush and the waste of paper.

Taking a blank piece of paper, Xiao Ming drew a structural drawing of the bicycle on it. Different from the strange looking bicycles in the west at the beginning, Xiao Ming directly designed the mature 28 bar self-confidence bicycle, that is, the beam bicycle in the early days of the founding of the people's Republic of China.

This kind of bicycle has a triangular stable lever structure in the middle, which can bear more weight.

The reason why he designed the old bicycle with this structure was mainly due to the current practical problems of the bicycle. After all, the bicycle at this time was used as a means of transportation, and the emphasis was on being strong enough to carry people and heavy objects.
