On the morning of December 26, the sixth year of the Qingli period, Wang Shouzhong came to the Political System Council and reported the good news that the rubber was ready.
Zhao Jun was overjoyed and went to the back garden with many prime ministers to observe the finished product.
Zhao Zhen introduced to everyone that the finished products were processed by him, and 90% of them were made of rubber raw materials.
Then he added about 0.5 parts egg white, 1.5 parts resin, 8 parts petroleum, carbon black, clay, stone powder, sand, glue, etc. as fillers.
By mixing and stirring many materials and then cooling them, they finally created a rubber that is durable, strong, heat-resistant and has friction.
After watching the various experiments, everyone praised Zhao Zhen's great invention.
Although Zhao Jun believes that its quality is still somewhat inferior to later rubber tires, it is already very good.
You have to know that this was in an ancient society without mechanization, chemical engineering capabilities, professional knowledge, and the scientific system had only just been perfected.
Zhao Zhen's actions were as fierce as a tiger, and it was like exploring a path out of the darkness, which was already commendable.
At least the rubber we have now is much stronger than the rubber that was just used in industry in history.
Zhao Jun walked in with Lu Yijian and others.
"I've met the Magistrate and the Associate Magistrate."
This shows how significant Watt's improvement of the steam engine was.
Zhao Jun immediately sent someone to send the rubber to the Institute of Physics, and at the same time sent the formula Zhao Zhen had formulated to the Institute of Chemistry to see if they could improve it on this basis.
Among them were some doctors, teachers, and academicians from the School of Physics, as well as some newly admitted Jinshi, clerks, or menial workers who were responsible for assisting them.
They saw that there were about two hundred people surrounding the parade ground, three layers deep and three layers deep.
The same is true for lead gaskets, which can also cause leakage or even explosion due to uneven pressure.
At this time, there was a huge steam engine on the railway tracks in the parade ground, and five iron carriages were pulled behind the steam engine.
He was a little tired and went back to sleep.
But the steam locomotive was invented in 1814, and when it was first invented it could only run at 8 kilometers per hour.
In the afternoon, Zhao Jun took the prime ministers to the Institute of Physics north of the imperial palace to see their progress.
Someone outside the crowd shouted.
Even in 1785, when Watt's steam engine was basically perfected, it was not popular in Britain.
There was even a long section of track on the parade ground, part of which has now been dismantled and used to make samples to be sent to the suburbs to build the railway that will be used for the display.
Therefore, the steam engines that used copper rings and lead washers in the early days were not reliable in terms of safety, and their sealing and power were seriously insufficient.
The steam engine had been experimented on this training ground before.
It was not until after 1860 that Watt's steam engine became completely popular in Britain. From the initial 500 or so machines, the number increased to more than 7,000 machines across the country.
After Zhao Zhen showed everyone his new invention in the morning, the meeting ended shortly afterwards.
The rails and iron carriages are not difficult to make. There is no need to say much about the carriages. As for the rails, you just need to make a mold for the train wheels first, and then make a mold for the rails so that the wheels and rails can fit together tightly.
The Institute of Physics had conducted experiments before. If copper rings and lead gaskets were used for sealing, the sealing would be seriously insufficient and the power generated would be insufficient.
After several improvements in 1769, 1776, 1782, and 1785, the efficiency of the steam engine reached its highest level, which was three times higher than the previous efficiency.
"Make way, make way, the Magistrate and the Associate Magistrate are here."
Then sleepers are laid underneath, and rails are nailed together with iron nails. The sleepers and rails are connected and laid on the ground to form a track.
The difficulty in making a steam locomotive lies in whether the steam engine pulling the car in front can provide enough power.
Because although Watt improved the steam engine in 1765, the results of his initial improvements were relatively mediocre.
Everyone gathered around the track in the center of the training ground, craning their necks to see if the experiment could meet the standards.
It wasn't until 1825 that the steam engine, improved by Watt, reached a speed of 25 kilometers per hour. By 1840, it could reach 4060 kilometers per hour.
Upon hearing that the prime ministers were coming, many research officials hurriedly made way.
He raised his head and looked into the field.
Today, the improvements made by the Institute of Physics have been thoroughly improved, with separate condensers, insulation layers outside the cylinders, oil-lubricated pistons, planetary gears, parallel motion connecting rod mechanisms, centrifugal governors, throttle valves, pressure gauges, safety valves, and so on.
This is the same speed as the first steam trains in history.
Zhao Jun waved his hand.
After receiving the finished rubber from the Institute of Physics, they quickly began to cut and polish the rubber, and then made rubber rings to serve as sealing rings for steam engines.
However, after running for a period of time, the copper ring is in a high-temperature steam environment for a long time, and due to thermal expansion and contraction, a large number of cracks will appear on the surface, causing serious air leakage in the steam engine.
Officials such as Guo Zi and Su Song who were debugging inside immediately came over and saluted.
The research institute is very large. It was previously the residence of the Ten Kings. It has a huge training ground, which is used to experiment with various inventions.
At this time, the Institute of Physics was quite lively. Many researchers heard that they had finally found a material that perfectly solved the sealing problem, so they put down their research and ran out to watch the fun.
When Zhao Jun came with many prime ministers, Dean Guo Zi was leading people to carry out the final debugging.
