Chu Ze looked at him with disgust again.
"This is just a model. We still have to think about how to make it." If it weren't for the fact that he didn't have paper and pen at hand, he would have used drawing at this time.
Zhu Ping let out a long "Oh" and asked again: "Then what are you going to do?"
Chu Ze glanced at the model in his hand.
He was textile quickly.
Although the workmanship is not very good, the general appearance is not bad.
He glanced at the circle of wheel shape, and said to Zhu Xi: "Be a bicycle."
"What car?" Zhu Xi took out his ears.
He has heard a carriage donkey car mundane car, but he has never heard of a bicycle.
He suspected that he had heard wrongly.
Or Chu Ze said wrong.
Chuze repeated again: "Bicycle."
Oh, he heard it right, Chu Ze didn’t say it either.
What people are talking about is bicycles.
But what is a bicycle?
"Is this car ... Is it used to eat? Or what kind of gadgets unique to your time?" Such a small, it is estimated that it can only be placed, let people watch and watch.
Just like the vase in their house.
Chu Ze's men kept moving and continued: "Bicycles cannot be eaten, they are a means of transportation."
Having said that, Chu Ze stopped his movement and thought carefully.
Then I looked at Zhu Xi seriously: "If you want to say it is something, it is right."
As the number of means of transportation increases, the uses of bicycles are also reflected in other aspects.
For example, fitness.
"But now, it's good to be a means of transportation." Bicycles don't have to choose the road. They can go on asphalt roads, cement roads, cobblestone roads, and gravel roads. They can even go on rural fields as long as the wheels can be accommodated. Geng can also walk. As long as Lan Ruoyan wants, she can ride her bicycle and go wherever she wants to go.
Chu Ze thought about it and thought it was pretty good.
But how to do it stumped Chu Ze.
It wasn't that the frame stumped him, but the tire.
In his memory, the earliest bicycle was no tire.
There are only two large round wheels made of wood.
Riding, it is naturally not good to feel.
Later, there was a rubber tire.
The problem appeared on this rubber tire.
There are two types of rubber.
One for natural rubber is extracted from plants such as rubber trees and rubber grass. The second is synthetic rubber, which is based on oil and natural gas as the raw material, and a polymerization of a single agglomeration with dizide and olefin.
Plants such as rubber trees were still living in South America at this time.
It will not enter China until the beginning of the 20th century.
As for synthetic rubber, they are only oil now.
And he couldn't get out of those aggregates.
What to do?
Chu Ze was worried.
But before worrying, he had to make a bicycle.
Lan Ruoyan played for a day, and when she returned to her residence, she still jumped alive.
Like countless haircuts.
Chu Ze, who was in his heart, played with Lan Ruoyan for two days, and he found a meter, entrusted Lan Ruoyan to Zhu Xi to take care of it, and he pierced himself into the factory and started making a bicycle.
For things like wheels and axles, Chu Ze used the simplest preparation.
The frame is made of iron, and the chain is created, as well as the most primitive gear used to drive the rear wheel rotation.
It's just easy to make skeleton.
According to Chu Ze, the workers made the framework without spending a few days.
Chu Ze assembled them one by one.
The assembly was completed, and he stuck again on the tire again.
At this time, Chu Ze was sitting behind a small table, staring intently at the bicycle rack opposite.
Don't think about rubber.
He couldn't get it out.
At least it can't be done yet.
He had to find another way.
As he was thinking about it, he suddenly thought of a legend about the origin of bicycle tires.
It is said that in the UK, there was a bicycle race.
At that time, the bicycle had no tires.
A contestant, who wants to win in the game, tries his best to find a way.
After much deliberation, he focused on the plastic pipe used for watering in the backyard.
He had an idea and cut out two sections according to the size of the wheel. After inflating them, he sealed them with glue and then tied them to the wheels.
The bicycle tied with plastic water pipes was much lighter than other bicycles, which successfully allowed him to win the championship.
Then, bicycle tires started to rise.
Like the former, plastic is also a material that he can't take out now.
Chu Ze sighed.
Can his bicycle only run "barefoot"?
Chu Ze frowned, his face resistant.
But there were no rubber trees in Ming Dynasty.
Can't synthesize.
Plastic cannot be synthesized.
When Chu Ze thought of this, he suddenly sat upright.
He murmured: "Yes, we really can't do synthetic plastic now, but isn't there still natural plastic?"
To be precise, it should be called natural resin.
According to Chu Ze, there are two ways to obtain plastic.
One is an object that uses monomers as raw materials and then combines them through a series of chemical reactions.
The other method is to use resin as raw material and go through a series of processes such as casting or extrusion under a certain temperature and pressure to create items.
Resin is also divided into synthetic resin and natural resin.
The current conditions are limited, he can't synthesize, but he can use natural resin.
He remembers that the rosin is more common in natural resin.
And it's insoluble in water.
Isn't it just right to make a tire?
When he said, Chu Ze immediately got up, and Manchuangzhou collected rosin.
It didn't take a few days to let Chu Ze find a sufficient amount of rosin.
After getting the rosin, he began to find a way to make the rosin into a tire.
If you want to make plastic from natural tree fingers, you have to take advantage of temperature.
Since that day, Chu Ze has been soaked in the stove room, constantly exploring the method of making tires.
In addition to the necessary rest, he even eats and sleeps inside.
In this way, time quietly slipped to Lan Ruoyan's birthday.
Lan Ruoyan is a little listless these days.
She has never seen Chu Ze for several days.
She asked Zhu Xi, and Zhu Xi did not tell her where Chu Ze had gone, but only said something and let her wait patiently.
When asked again, he just smiled and didn't answer.
If you can't ask anything, Lan Ruoyan will stop asking.
Until today.
Seeing his languid expression, Zhu Xiang asked with concern: "Why don't you eat? Is the food not to your liking? How about we have someone prepare it again?" When Zhu Xiang was about to call someone, Lan Ruoyan stopped him: "Forget it, these are all. fine."
It is good to say on my mouth, just don't move chopsticks.
Zhu Xi thought for a while and smiled secretly.
"So, you eat first, after dinner, let's take you to a place of interesting, how about it?"
Lan Ruoyan still lacked interest.
She doesn't want to go now, just want to see Chu Ze.
Then, she heard Zhu Xi said, "Maybe you can see the person you want to see there."
Isn't the person she wants to see brother Chu Ze? !
Lan Ruoyan's eyes brightened, surprised: "Really?"
"Really, hurry up and eat. We'll go there after you finish." Zhu Xi moved the dishes in front of her and urged. (End of chapter)
