Chapter 821: Rubber products

Qingzhou, which is about to enter June, is already a little hot, and the bright sunlight is scorching the concrete road and it is a little steamy.
Xiao Ming returned to the palace for lunch and waited for Lu Tong in the imperial study room.
In the afternoon, when the hour hand of the pendulum clock pointed to two o'clock, Lu Tong arrived outside the Imperial Study Room on time, and there was a young man who was about 30 years old with him.
The young man wore a white gown from Qingzhou University and held a bunch of things that Xiao Ming knew well in his arms.
"See the emperor."
After entering the imperial study room, Lu Tong saluted Xiao Ming.
After getting up, Lu Tong introduced to Xiao Ming: "The emperor, this is a student from Qingzhou University, named Liu Chuanzhi. It was the official who handed the rubber to them."
"Liu Chuanzhi? Good name." Xiao Ming said with a smile.
"Praise the emperor Xie." Liu Chuanzhi spoke a little trembling, obviously very nervous.
Xiao Ming had a smile in his eyes. These people who are devoted to scientific research have not dealt with outsiders for a long time, so their characteristics are similar.
He said: "You don't have to be nervous, I am not a cannibal tiger, these are all rubber products you made?"
Only then did Liu Chuanzhi remember the rubber in his arms, and said hurriedly: "Yes...yes, the emperor, according to the information provided by the emperor, Caomin has successfully mastered the method of vulcanizing rubber, plus the metal mold provided by the equipment department, and now he has made a Batch rubber products."
Xiao Ming nodded. The rubber sent by the Dutch can only be called raw rubber. This raw rubber is very sticky and easy to break, so it cannot be used in industry.
The vulcanized rubber is called cooked rubber. This type of rubber has no problems with raw rubber. It has high elasticity, heat resistance, tensile strength, and does not dissolve in organic solvents. Contemporary rubber products are basically All of them are vulcanized rubber.
Looking at Liu Chuanzhi's arms, Xiao Ming's smile became stronger. In fact, it is not very difficult to shape rubber, because rubber will become liquid under high temperature, which is similar to molten steel.
Molten steel can be molded by iron, and this rubber can also be molded by iron. This is also the contemporary way to shape Xiao Ming.
The only thing that needs to be done is to vulcanize the rubber before shaping.
This kind of vulcanization requires the use of a substance as a crosslinking agent, which is sulfur, and vulcanized rubber of different qualities can be produced according to time and temperature. There are many ways to vulcanize. The simplest method is to mix the two directly and heat it.
"The emperor, this is a tire, this is a hose, and this is a piston..." Liu Chuanzhi took out all the products he brought out like a few treasures.
Xiao Ming took them from him one by one, and looked at them repeatedly before putting them down.
For him, rubber is a crucial part of industrial development, such as shoe soles, warm water bags and elastic bands used in daily life.
Medical gloves, blood vessels and various tires for transportation, industrial conveyor belts, agricultural irrigation and drainage hoses, sealing equipment for scientific experiments, military aircraft, tanks, artillery, etc. Do not open rubber.
The West is able to push the East far away in science and technology, largely because they control rubber, but unfortunately, like contemporary times, Europe is still in control of rubber in this era.
Although he got some rubber tree seeds from the Netherlands, it takes a long process to get from seed to tree.
Of course, he still has a solution, which is rubber grass, but according to the data, the origin of rubber grass is in contemporary Xinjiang Yili, and rubber grass is obviously still under the control of the barbarians in this era.
After he drives away the barbarians, he can plant rubber grass in this area, but it seems to be a problem to lay down this place and hold it.
Therefore, the most suitable way for him is to buy rubber from Europeans.
As for the occupation of South America, he still needs a long way to go. Even if he now has a fleet of armored ships, he needs fixed ports to provide fresh water and coal from Da Yu to South America, otherwise his fleet will not Arrived in the Americas will be paralyzed on the way.
"Great, great." Faced with one rubber product after another, Xiao Ming was inevitably excited. With rubber, many machines can be realized.
And he thinks that one of the problems that should be solved most is the traffic problem.
The most profound experience for Xiao Ming in this era is that if he wants to be rich, he must first build roads. Only with convenient transportation can the exchange of various resources be rapid.
Lu Tong and Liu Chuanzhi looked at Xiao Ming excitedly, with thick smiles on their faces.
Xiao Ming put down the rubber products such as medical blood vessels and said, "What reward do you want?"
"The emperor, this rubber is just a matter of effort, relying on the information provided by the emperor, the lower officials dare not ask for rewards." 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 and opened his mouth and finally said nothing.
Upon seeing this, Xiao Ming said: "Liu Chuanzhi, from now on, the rubber of the great Yu country will be handed over to you. Now you naturally don’t have to be polite. Let’s do this. In order to allow you to concentrate on rubber production, I will reward you with silver. How about giving you another fifty acres of farmland?"
"Xie Huang Shang Long En!" Liu Chuanzhi was trembling with excitement.
Before that, he was just a poor scholar. The reason why he entered Qingzhou University was because there was no money left at home to allow him to go to Beijing to take the exam, but he did not expect that this decision brought him another chance.
Xiao Ming helped Liu Chuanzhi, who bowed his gratitude, and said: "I am not a stingy person. As long as you can do things down-to-earth and make contributions to the Great Yu Kingdom, title, land, and money are not a problem. The army has seized large tracts of land outside the pass, so you don’t have to worry that I won’t be rewarded.
Liu Chuanzhi nodded deeply ~EbookFREE.me~ and asked them some questions about rubber. Xiao Ming asked them to go back temporarily.
When the two left, he immediately sat down and picked up the pen.
Now this pen can only write while being stained with ink. Now that he has rubber, he can finally have a pen that can absorb water. After this, he is going to recommend the pen to all officials in the country for office work, eliminating the need to write calligraphy. Time also saves paper waste.
Taking a blank sheet of paper, Xiao Ming drew the structure of the bicycle on it. Unlike the strange bicycles in the West, Xiao Ming directly designed a mature two-eight bars confident bicycle, which is the early days of the founding of the People’s Republic of China. Cross beam bicycle.
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 mainly took into account 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 and capable of carrying people and heavy objects.
