Qingzhou, which is about to enter June, is already a little hot, and the bright sun is scorching the cement road, and some people are steaming. Pen ~ fun ~ pavilion www.biquge.info

Xiao Ming returned to the palace for lunch, and then waited for Lu Tong in the imperial study.

In the afternoon, when the hour hand of the pendulum clock pointed to two o'clock, Lu Tong arrived outside the imperial study on time, and with him came a young man of about thirty years old.

The young man was dressed in a white caftan from Qingzhou University, and he was holding a bunch of things that Xiao Ming was very familiar with in his arms.

"See the Emperor."

Entering the imperial study, Lu Tong and the others saluted Xiao Ming.

After getting up, Lu Tong introduced to Xiao Ming: "Your Majesty, this is a student of Qingzhou University, named Liu Chuanzhi, and the lower official handed over the rubber to them. “

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

"Thank you for your praise." Liu Chuanzhi spoke a little tremblingly, obviously very nervous.

Xiao Ming had a smile in his eyes, these people who were dedicated to scientific research had not dealt with outsiders for a long time, so their traits were similar.

He said: "You don't have to be nervous, I'm not a man-eating tiger, these are the rubber products you made?" “

Liu Chuanzhi only remembered the rubber in his arms at this time, and hurriedly said: "It's... Yes, the emperor, according to the information provided by the emperor, the grass people have successfully mastered the method of vulcanizing rubber, plus the metal molds provided by the equipment department, and now a batch of rubber products have been manufactured. “

Xiao Ming nodded, the rubber sent by the Dutch can only be called raw rubber, this kind of raw rubber is very sticky and easy to break, so it cannot be used in industry.

The vulcanized rubber is called cooked rubber, this kind of rubber has no raw rubber problems, has high elasticity, heat resistance, tensile strength, and will not be dissolved in organic solvents, contemporary rubber products are basically vulcanized rubber.

Looking at Liu Chuanzhi's arms, Xiao Ming's smile became more and more intense, in fact, the shaping of rubber is not very difficult, because at high temperatures, rubber will become fluid, which is similar to molten steel.

Molten steel can be molded with iron, and this rubber can naturally be molded with iron, which is also a contemporary method for Xiao Ming.

The only thing that needs to be done is to vulcanize the rubber before shaping.

This vulcanization requires the use of a substance as a crosslinker, which is sulfur, and according to time and temperature, vulcanized rubber of different qualities can be produced, and there are many vulcanization methods, the simplest of which is to mix the two and heat them directly.

"Your Majesty, this is a tire, this is a hose, and this is a piston......" Liu Chuanzhi took out all the products he brought like a few family treasures.

Xiao Ming took them from him one by one, looked at them repeatedly before putting them down.

For him, rubber is a vital part of industrial development, such as shoe soles, warm water bags, and elastic bands used in daily life.

Gloves used in medical treatment, various tires used in blood vessels and transportation, conveyor belts used in industry, drainage and irrigation hoses used in agriculture, sealing equipment used in scientific experiments, and aircraft, tanks, and artillery used in military use are all inseparable from rubber.

The West's ability to pull the East far away in terms of technology is largely due to their control of rubber, but unfortunately, as in contemporary times, rubber in this era is still controlled by Europe.

Although he got some rubber tree seeds from the Netherlands, it took a long time to get from seed to tree.

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

He waited for the barbarians to drive out the barbarians before he could plant rubber grass in this area, but it seemed to be a problem to conquer the place and hold it.

So, the most suitable thing for him at the moment is to buy rubber from the Europeans.

As for the occupation of South America, he still has a long way to go, even if he now has a fleet of ironclad ships, which will need a fixed port to provide fresh water and coal between Dayu and South America, otherwise his fleet will be paralyzed halfway before it reaches the Americas.

"Great, great." In the face of one rubber product after another, Xiao Ming is inevitably excited, with rubber, many machinery can be realized.

And he believes that one of the most important problems to be solved at present is the problem of transportation.

The most profound experience of this era for Xiao Ming is that if you want to get rich, you must first build roads, and only when the transportation is convenient, the exchange of various resources can be rapid.

Lu Tong and Liu Chuanzhi looked at Xiao Ming excitedly, with a thick smile on their faces.

Xiao Ming put down rubber products such as medical blood vessels and said, "What reward do you want?" “

"Your Majesty, this rubber is just a gesture, relying on the information provided by the emperor, and the lower officials 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 laughed, while Liu Chuanzhi looked embarrassed, opened his mouth and finally didn't say anything.

Seeing this, Xiao Ming said: "Liu Chuanzhi, in the future, the rubber of this great Chongqing country will be handed over to you, now you naturally don't have to be polite, so let's do it, in order for you to be able to concentrate on the production of rubber, this time I will reward you with a thousand taels of silver, and then give you fifty acres of farmland, how about it?" ”

"Thank Emperor Longen!" When Liu Chuanzhi heard this, his body trembled a little excitedly.

Previously, he was just a poor scholar, and the reason why he entered Qingzhou University was because his family had no money left for him to go to Beijing to take the exam, but he didn't expect this decision to bring him another opportunity.

Xiao Ming helped Liu Chuanzhi, who bowed down to thank him, and said: "I am not a stingy person, as long as you can do things in a down-to-earth manner and contribute to the Great Yu Kingdom, titles, land, and money are not a problem, and now that my army has seized a large area of land outside the pass, you don't have to worry about me having no land to reward." “

Liu Chuanzhi nodded deeply.

After asking the two of them some questions about rubber, Xiao Ming asked the two to go back for the time being.

As soon as the two were gone, he sat down and picked up his pen.

Now this fountain pen can only be written while stained with ink, now with rubber, he can finally have a fountain pen that can absorb water, after this matter, he is ready to recommend the pen office to all the officials of the Great Chongqing State, saving the time to write brush words and save the waste of paper.

Took a blank piece of paper, Xiao Ming drew a diagram of the structure of the bicycle on it, different from the bicycles with strange shapes in the West at the beginning, Xiao Ming directly designed a mature two-eight-bar self-confidence car, that is, the beam bicycle in the early days of the founding of the contemporary People's Republic of China.

This bike has a triangular stable lever structure in the middle, which can hold 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.
