After Zhu Jingyuan worked hard for two months, Yu Duxue's stomach also moved, and she was suspected of being pregnant.

At the request of Liang Yunying, he began to raise a fetus with Liu Muyun, and he couldn't run around with Zhu Jingyuan.

So the ones who followed Zhu Jingyuan as a secretary became the maidservants who had been trained for more than a year.

Today, Zhu Jingyuan is followed by Chunxiang and An Xiaona.

Zhu Jingyuan took two maidservants and sat in his classic car worth millions.

Guards on motorbikes escorted the front and rear.

The completely "mechanized" team left the palace and went to the petrochemical experimental base outside the city.

Most of the experiments related to petrochemical industry have certain dangers and are basically toxic.

】

People in this era don't know enough and don't care much, but Zhu Jingyuan's habits in his previous life made him instinctively stay away from these things.

Therefore, the petrochemical experiments were placed in the downwind direction outside the city, and there was some distance from the planned new urban area.

Zhu Jingyuan sat in the car, looking at the scene outside through the window, which has changed greatly compared with years ago.

The main reason is that the area of residential areas has doubled again, and the population of the city has also doubled.

Due to the increase in the number of workers, the construction of the royal palace of the new royal palace was completed earlier than expected, and now it has entered the stage of full renovation and arrangement.

The renovation of the main palace for living is basically over, and it is actually ready to live in, but Zhu Jingyuan plans to wait until it is all completed before officially moving.

There is now a larger construction site outside the palace.

Moats, ponds, rockeries and other ancillary buildings outside the palace.

Moats and ponds dug up mounds behind the palace to create a rockery like Jingshan behind the Forbidden City.

This rockery will also be circled out and connected to the royal palace as part of the back garden.

Although the first seawater chemical plants have been put into operation, the water produced by the factories cannot be wasted on decorative ponds, but is intended for drinking and industrial use.

Therefore, the pond and the moat are directly connected to the sea, and two ditches are dug to connect directly with the sea.

Outside the front gate of the royal city is the government office buildings of various departments of the kingdom, which have now been completed and have entered the renovation stage.

Zhu Jingyuan's convoy ran for more than 10 minutes before arriving at the petrochemical test site.

Zheng Fuguang has already waited here with the person in charge of the petrochemical experimental base.

Zhu Jingyuan got out of the car and followed them into the laboratory, listening to the person in charge introduce the situation to him.

From raw materials to semi-finished products, to a variety of finished products with different properties.

There are direct finished products in the form of blocks, and there are "granules" made into granules according to Zhu Jingyuan's requirements.

There are also films, rods, tubes, and actual products wrapped in wires for various tests.

Polyethylene belongs to white plastics, is the most common white plastic, and the output of all types of polyethylene can account for two to three percent of the world's total plastic production.

It can be used in most common places where human life can be used.

Films for commodity packaging, cable coverings for protection and insulation, various pipes and engineering plastics.

Moreover, polyethylene can be regarded as a large category, rather than a plastic, according to the polymerization method, molecular weight, chain structure, can be divided into several categories, will have different properties, and also have different uses.

With the size of the big food country, as long as the polyethylene industry can be done well, even if it is a simple production of this large type of plastics in the future, it will be able to occupy a place in the industrial chain of the Great Ming Dynasty.

It is enough to maintain the dignity of an industrial country, not just a warehouse of raw materials.

Zhu Jingyuan picked up a plastic pipe and looked at this thing, which was very common in his previous life, and now he finally sees it again:

"We have a lack of other resources in our big food country, and there are no iron ore and coal mines at all, so only oil resources are quite abundant.

"This plastic should be able to replace steel in many places, which can greatly reduce our construction costs.

"All of you present are the great heroes of our Great Food Country, and also the great heroes of our Daming Airlines.

"I'm not going to talk any useless nonsense, all the craftsmen involved in R&D will be paid a year's salary this month."

Uncontrollable cheers erupted in the surrounding group of craftsmen.

Zhu Jingyuan's generous reputation has long been heard of by many people, but it is completely different from the actual experience.

Lu Xueqin, a major engineer in the chemical laboratory, immediately couldn't help but postpone and said:

"Your Highness is so generous, the design direction is all formulated by His Highness, and even the most critical hints are given.

"We people just put in a little bit of effort, made all the experiments, made things."

Zhu Jingyuan smiled and waved his hand and said:

"Don't be modest, Lu Gong, without you and all the craftsmen, I really can't do it myself.

"I just thought about the direction, whether it is correct or not, whether it can succeed or not, is all the credit of you.

"And don't be complacent, we have an equally important task ahead of us.

"Rayon suitable for weaving, as well as elastic yarn with great elasticity, can replace natural fibers in textile materials.

"If we can produce materials with the nature of silk in factories, there will be an unprecedentedly huge market.

"I don't think it's too much to even be the backbone of our big food country."

In this day and age, there is no market for concepts such as environmental protection.

The only environmental projects that have made a difference are the two major rainforest reserves in Zhujingyuanti.

The nominal protection of the rainforest was achieved through the administrative means of the League of Nations.

People in this era have not yet begun to pursue "pure natural" in a daze.

Even many times the situation may be the other way around, and many intellectuals feel that it is better to make it man-made.

Man-made products are the crystallization of science and technology, the crystallization of great human wisdom, and the symbol of more civilization.

Putting the fur of an animal directly over the body means barbarism and ignorance.

If Zhu Jingyuan makes rayon, it can be sold for more expensive than silk immediately.

Moreover, many properties of chemical fibers are far beyond the reach of natural fibers.

Nylon, also known as nylon, is much stronger and more abrasion resistant than natural fibers such as cotton and linen, and will not mildew in humid environments in the tropics and subtropics.

Therefore, it is a very widely used military uniform, very important military uniform and carrying gear material, and it is also the main material for making parachutes, and its performance far exceeds that of silk.

At the same time, it is also widely used in civilian use, and is an important material for making jackets, sportswear, raincoats, socks, tents, fishing nets, conveyor belts and other items.

After the development of rayon, the big food country will be able to develop the textile and garment industry in the desert without relying on agricultural cultivation.

Zhu Jingyuan has already made arrangements for rayon.

While the craftsmen were focusing on polyethylene, exploratory experiments with rayon had already begun.

At this time, Lu Xueqin immediately said very seriously:

"Your Highness can rest assured that after the success of the polyethylene experiment, a small number of people will be left to continue to improve and optimize, and cooperate with the factory to achieve mass production, and most craftsmen will immediately turn to the research of rayon.

"We have followed His Royal Highness's tips to find suitable polymers and explore suitable polymerization methods in diamine, diacid, and amide materials, and we are already a bit eyebrow-raising."

Zhu Jingyuan was very simple and said rudely:

"Okay, keep working hard, after the rayon is made, everyone will be paid another year's salary.

"But don't get busy right away, this thing can't be done in a day or two.

"I just got the polyethylene out, everyone has been working hard for so long, let's relax and rest first."

Lu Xueqin subconsciously said:

"Thank you Your Highness for your kindness, but we don't need to take a special break, we must get rayon out as soon as possible......"

Lu Xueqin and the craftsmen are more conflicted in their hearts, and of course they want to rest from the nature of human beings.

After all, for the sake of polyethylene has been liver for a long time, and no one does not want to hope for relaxation and rest.

But the reward given by Zhu Jingyuan is really attractive, and it is another year's salary to make rayon.

The boss of his own family has always done what he says, and he does not have a lake at all when he sends money.

So I instinctively want to continue to burst the liver and get the rayon out as soon as possible.

But Zhu Jingyuan directly waved his hand and interrupted:

"Work should be a combination of work and rest, don't squeeze your body too much, otherwise you don't know when you will suddenly fall ill.

"I also hope that you can continue to work for my Dashi Country and Daming Airlines for 60 years.

"When I say rest, I will rest first, don't hold on."

Under Zhu Jingyuan's rigid requirements, Lu Xueqin and the craftsmen did not hold on, and decided to take an eight-day holiday from tomorrow.
