The Rise of Ming Dynasty 1646

Chapter 446 Vulcanized Rubber
And right now there is an opportunity to realize the "household joint production contract responsibility system" - the war has caused many lands to become unowned, and a large number of lands under the names of captive officials have also been confiscated as official land. Calling on the clan to donate land, the amount of land gathered is already very considerable.

When the work of counting the acres of land is completed, it is believed that the number of official lands will be enough for most poor people to barely survive.At the same time, due to the destruction of Jianlu, the ownership of the land in Jiangbei was almost completely disrupted. After the officials were eliminated, more than half of the land could even be collected as official land.

With this large amount of land in hand, the problem of land annexation will be effectively resolved, so that the life of the people at the bottom will be stable.

Of course, Zhu Linming also knew that, given the social situation at the end of the Ming Dynasty, it was definitely impossible to completely copy the "household joint production contract responsibility system".

First of all, based on the bureaucratic thinking of the Ming Dynasty, the officials would do their best to turn the official land into their own private property, just like the Weisuo farmland in the Ming Dynasty, and finally all became the land of military officers.

Secondly, the common people will definitely have doubts about the situation that "the land does not belong to me". Once they have savings, they will still try their best to buy land by themselves.And when a large amount of land is converted into official land, it will cause scarcity of land that can be purchased, so that the price of land will skyrocket.

The reason for this situation is the peasants' mistrust of the imperial government's policies, fearing that one day the contracted land will be taken back without reason.

Finally, because the contract responsibility system has weakened the dominance of the gentry and landlords, they will find ways to disadvantage the farmers who contracted the land, and the farmers who are alone may be threatened to return the contracted land.

Therefore, after repeated deliberation, Zhu Linmi finally decided to change the so-called official land to "Huangzhuang", and the land is attached to the name of the emperor.

The term "joint production contract responsibility system" was also not mentioned, and it was only said that it was farming for the emperor. All the rules and regulations of "contracted land" are promulgated in the form of imperial edicts.

The last and most important thing is to come up with the slogan - pay all the emperor, and the rest is your own!

With the golden words of the emperor, the worries of the lower-level farmers can be dispelled to the greatest extent, and they can plant "contracted fields" with peace of mind.And those officials who wanted to take advantage of the official land would not dare to attack Huangzhuang if they had the guts.

As for the landlords and gentry who wanted to bully the peasants who contracted the fields, it was probably the eunuchs sent by the palace to handle these matters.These people have a lot of ways to deal with the gentry and the like. You can see how miserable Wei Zhongxian made the officials of the Donglin Party back then.

Taking advantage of the free time in the past few days, Zhu Linmei carefully sorted out the "Huangzhuang Contracting" system again, and waited for the data on unclaimed land from various places to be collected.

He was thinking about where to start the "land reform" when Xu Erlu came again with several people behind him.

"You don't need to be too polite." Zhu Linmei helped the three of them up, and asked Xu Er Ludao, "Why did Weiyuan make a special trip to Shaoxing, but what's important?"

"Return to Your Highness, you previously ordered that the Frankie will notify you immediately when the so-called 'rubber' arrives. Mr. Song asked me to bring a sample to show His Highness." Xu Erlu gestured to the people behind him again, "This is Mr. Song, according to His Highness's instructions, specially selected someone who is good at chemical experiments from Fujing Laboratory."

He specifically singled out one of them, "His name is Yao Qisheng, and he is the most skilled in the laboratory."

"Yao Qisheng?" Zhu Lin was taken aback. Could this be the governor of Fujian in the Qing Dynasty who insisted on moving to the forbidden sea and trapping Zheng Jing to death?This person is quite scheming, but in history, Nanming was almost dead when he was still young, so he could only serve in the Qing Dynasty.

Zhu Linmi asked Yao Qisheng a few more words, and according to what he said about his own situation, nine times he was the "Governor of Fujian".

However, Yao Qisheng is only 22 years old now, and he has already devoted himself to Daming, so there is no reason to play for Jianlu again.And for now, he chose to devote himself to chemistry.

Zhu Linmi suddenly remembered the TV series she had watched in her previous life. Yao Qisheng was not good at reading sage books when he was young. Historically, he did not pass the exam until he was nearly 40 years old.It seems that in this life, he has found his strengths and simply abandoned literature and theory.

Xu Erlu pointed to the other person he brought, "His Royal Highness, this is the top craftsman of Macedo Watch Workshop, named Wen Xinping, who is good at making all kinds of exquisite appliances. The boring machines and drilling machines created by His Highness, he They can all be made on their own.”

Zhu Linmin nodded, and asked again, "Did you bring all the equipment used in the experiment?"

"Return to Your Highness." Yao Qisheng clasped his hands, "The students brought half of the laboratory with them."

"Okay." Zhu Linmei said with satisfaction.With these people present, the trial production of vulcanized rubber can begin.

Rubber is an extremely important raw material in industrialization.Even today, it can be used to make products such as wheels, raincoats, and sealing rings, and can even be exported overseas as high-tech products.

In fact, rubber has long been used in Europe to a certain extent, but it is limited to raw rubber.The glue picked directly from the rubber tree becomes soft when heated, hardens and becomes brittle when cooled, is difficult to shape, and is easy to wear and tear, so the scale of use is extremely small.

It wasn't until the mid-nineteenth century that Americans invented vulcanized rubber technology that stable and durable rubber was really widely used.

In fact, the vulcanization technology is very simple to say, it is to add sulfur to the rubber, and then add heat.But it is this little trick that humans have spent hundreds of years to finally master.

It's just that Zhu Linming only knows that adding sulfur to rubber can greatly improve its performance, but he doesn't remember exactly how much to add, how to add sulfur, how to heat after adding sulfur, temperature control, vulcanization time, etc.

But he believes that when Goodyear accidentally added sulfur to rubber to obtain qualified vulcanized rubber, it means that the whole process should not be complicated.

So before he left Fujing, he ordered Song Yingxing to find students who were familiar with chemical experiments to conduct trial production of vulcanized rubber.Song Yingxing has been running Gezhixue for one year. During this period, he has trained many students with basic skills, and the laboratory was established when he was in Ganzhou.

Now that these students have learned some basics, they can carry out some practical experiments.

Zhu Linmei asked Xu Erlu to move the rubber and experimental equipment he brought to the East Courtyard of Prince Lu's Mansion, and began to explain the rubber vulcanization process to Yao Qisheng and others on the spot, and asked them to repeatedly test the ratio of sulfur addition, temperature and time. kind.

According to his request, Wen Xinping led several craftsmen to make molds, and as soon as the qualified vulcanized rubber was produced, it could be used to process practical appliances immediately.

The first thing they made was a ring-shaped mold with the thickness of the forearm. For the time being, only Zhu Linmin knew that this was the sealing ring of the Francois machine gun.

Zhu Linmei was leading everyone to work in the east courtyard when she saw Shi Lin approaching and said to him, "My lord, there is an old friend asking to see me."

"Old friend?" Zhu Linmi asked suspiciously, "Who is it?"

Shi Lin put a feather in his hand, "He didn't say his name, he just said that you will know it when you see it."
