Chapter 472： Vulcanized rubber

After a trip to the palace, Wu Changqing certainly wouldn't go back immediately.

He is going to take a stroll in Nanjing, and by the way inspect his concerns.

In the university hall, he hasn't come to teach students for a long time.

It is more important to deal with major affairs of the government than to teach students.

Nowadays, the university hall has entered a benign development stage, and the top group of people are conducting various scientific researches while studying on their own.

The next batch of people learnt, but they acted as teachers in the school, imparting basic knowledge to others.

Their abilities are limited, and they cannot be expected to teach how well and how deep they are.

Most of the time, they can only teach a little, and put those theories into the heads of other students.

As for whether you can understand it and whether you can be inspired by it, it all depends on the students' own talents.

I want to learn the essence of self-study mainly by talent and hard work.

Those who are talented and willing to work hard will be cultivated by the academy.

Ordinary teachers can't answer their questions, they can ask the top people for advice, and if they're lucky, they can be their assistants and learn by doing.

This mechanism of cultivating talents is certainly not as efficient as the schools of later generations.

However, this is already the most efficient method at the moment.

Relying on this mechanism, Dahua has cultivated more than ten talents equivalent to the undergraduate level of later generations in less than two years, and even more than 200 talents equivalent to high school graduation.

The junior high school level is more, there are already thousands.

Having a high school level is actually quite remarkable. With this level, coupled with the funds provided by the court for them to study, they can already produce some results.

Coupled with Wu Changqing's guidance, providing ideas and even technical support when necessary, these people's current research and development speed is quite amazing.

Currently, there are already several strategic-level R&D projects in the university hall.

The first is the steam engine project. The steam engine needs to continuously improve its performance, require more power, and a smaller size.

The second is a material research project, which studies basic materials such as various alloys and ceramics.

The steam engine has been unable to achieve major breakthroughs. The fundamental reason is that no suitable materials can be found.

Ordinary steel cannot withstand the high temperature and pressure, and even a high-power steam engine will not last long.

At this time, it is necessary to add a certain amount of other rare metals to the steel to produce special steel that is resistant to high temperature and pressure.

In the original history, this process was very difficult. It relied on countless people to try little by little. After countless trial and error, some laws came to an end.

The process of getting acquainted with other rare metals alone took I don’t know how much time.

But now Dahua doesn't have to work so hard to study materials. Most of the metals are already listed in the textbook. They only need to look for it according to the textbook.

Today, Dahua has discovered and confirmed more than ten kinds of metals.

However, the preparation of other rare metals is still a big problem for the time being.

The third research on the use of rubber.

This is the direction Wu Changqing personally pointed out. He bought a batch of natural rubber from a Western businessman, and then asked the people in the university to study how to use it.

Rubber is a very important material in human history, and it can even be called a strategic material.

In transportation, all kinds of tires need rubber.

In industry, rubber is needed for tapes, hoses, belts, etc.

In the military, a tank requires at least one thousand catties of rubber, and a 30,000-ton warship has fifty to sixty tons of rubber.

Even Dahua can't build tanks and large warships, but rubber is used to make tents, raincoats and leather shoes are excellent.

In the future, the soldiers' legs will fester in a few days without a pair of long rubber shoes in Southeast Asia where it rains all the year round.

Let alone the current technology, in the 1960s and 70s of the 20th century, foreign soldiers who were not used to the local climate would suffer in this environment.

To fight in such a place, a pair of dry socks and a pair of long leather boots are more important than the rifle in your hand.

Construction field, medical field, electrical communication...

In short, the status of rubber is irreplaceable.

"How is the progress of rubber research now?"

Wu Changqing asked Fei Yufeng, the person in charge of the next project.

Fei Yufeng is also one of the top students, and his talents are comparable to those of Feng Xianzhong and others.

"Students are ashamed that they cannot solve the adhesiveness and breakage characteristics of rubber for the time being. If these two problems cannot be solved, the rubber will become soft when heated, and it will become brittle and hard when it is cold, which is not practical. "

Fei Yufeng said depressed that several other projects are now in full swing, but his project has not made progress, making him very anxious and anxious.

"You can try adding some sulfur to this rubber. As far as I know, there will be a certain reaction between the rubber and the sulfur in the sulfur. After the reaction, the vulcanized rubber will become elastic, resistant to high temperatures, and increase tensile strength.

However, you need to find out how much you need to add and how to add it. "

Wu Changqing only knows that rubber needs to be vulcanized before it can be practical.

But he didn't know exactly how to vulcanize.

Of course, he can go directly to the system mall to redeem this technology, but he did not do so.

After all, Dahua's demand for rubber is not so urgent for the time being.

More importantly, Wu Changqing needs talents, who need to rely on his own research and exploration to grow.

Tell the other party everything directly, you can only train the other party to be a skilled worker, but you can't train him to be a talented person with research ability.

And talent is what Wu Changqing attaches the most importance to.

There are no hundreds of thousands of talents to implement it, and his empty technology is useless.

Unless he doesn't deal with major affairs of the government every day and devotes himself to scientific research.

In that case, it won't take long for those powers to fall into the hands of others. In the end, he may be helping others build a better society.

"Vulcanization, students try immediately."

Fei Yufeng said.

Regarding Wu Changqing's words, these emperor students all believed unconditionally.

Wu Changqing said that vulcanization is useful, so he decided to vulcanize rubber as a way.

After all, Wu Changqing has created too many miracles. In their view, Wu Changqing is omniscient and knows everything.

Their admiration for Wu Changqing is much higher than that of others.

As the saying goes, the more people who know, the more ignorant they feel.

Those who know a lot about them know how amazing the inventions and theories that Wu Changqing has made.
