Hand over the jade seal first [Infrastructure]

Chapter 244

Xiao Zirong now has a total of ten gold cards in his hand. This was made in the early stage. Because they are all handmade, ten gold cards are not easy to make.

It's not difficult to make this look, but the problem is that he added anti-counterfeiting inside, otherwise anyone can make such a gold card, so what's the use?

In addition to the serial number of the gold card, the most important thing is that there will be a petal at the bottom corner of the back of the gold card. These petals are randomly picked from the garden, and then made into a label, inlaid on the gold card. Attach another coat of varnish.

Because each petal in nature is different, and the number of gold card users in the early stage is also small, the serial numbers and petal characteristics of these gold card users will be recorded and handed over to each store.

Of course, this anti-counterfeiting method is still very backward, and it is as difficult as finding someone through a portrait, but this is the best anti-counterfeiting method that Xiao Zirong can think of so far.

As for the more gold cards in the future, the anti-counterfeiting methods will also be improved at that time.

Xiao Zirong wanted to grab it with both hands now, and Yuan Jia asked for a lot of salt in one go, and then came embarrassingly - their ship couldn't transport that much.

Xiao Zirong: ...

He vaguely remembered that he wanted to build a ship first, but at that time he didn't expect that he would be sent to guard the country, so he didn't think that he would build an industrial zone first.

Now that he is here, he wants to lay the groundwork first, otherwise, even if the ship is made, there is no way to mass-produce it or form a fleet.

Xiao Zirong was not in a hurry to start building the boat, he had to take his time, his current stall was already very large, and no matter how prone to problems, he didn't have so much energy to take care of it.

However, they can wait for the small trains in the garden to be made, and get the information of the boats for them to study by themselves.

Of course, the focus now is on tempered glass.

Since the steam engine has entered a relatively stable stage and started to make walking parts, Xiao Zirong began to design the appearance of the small park train.

The small garden train is different from ordinary trains. It wants to look good, and because it travels slowly, it does not need to reduce wind resistance, so it can use an older shape instead.

Originally, Xiao Zirong simply wanted to use the current architectural appearance, but after thinking about it, he found that he needed to make glass windows on top of the small garden train, that is, open a skylight.

Otherwise, when you get to the tunnel in the water, you can only look at the windows on both sides of the small train, which is boring. What can you see if the field of vision is too narrow?Then the meaning of his underwater tunnel is gone.

So there must be glass on it to look good. He is not crazy enough to make it into a glazed car. Of course, even if he wants to, it is not easy to do.

Just for the sake of safety, the small garden train must also be equipped with tempered glass, and even the steam trains in the future will also use tempered glass, all for the sake of safety.

The production of tempered glass first needs to eliminate internal stress, and secondly, it needs to cool down to room temperature quickly and evenly through heat dissipation, so that tempered glass can be produced.

Yes, tempered glass doesn't actually have steel in it.

Elimination of internal stress is actually to use the quenching method to directly heat the flat glass, wait until it is heated to soften, and then let it cool down quickly and evenly, so it is not feasible to throw the glass directly into the ice cellar , can only be placed in the refrigerated room next to the ice cellar, and then blow it evenly with a fan.

In this way, after the glass cools down, it becomes tempered glass.

Of course, this is said in theory, but no one knows whether uniform blowing can be achieved.

The best way to do this is to blast cool air with a multi-head nozzle.

But the problem with multi-head nozzles is that they don't have an air compressor, and they can't extract air to compress and then spray.

So Xiao Zirong's idea is to get a bunch of small fans, which can cover the entire area of ​​the flat glass, and then blow air on it. The speed of each fan is the same, so that the purpose of uniform cooling can be achieved to some extent.

Of course, this is his idea, and it can be regarded as his invention. As for whether it can work, it still needs to be tested.

After all, even if Xiao Zirong searched all the information for this method, he could not find a similar technique.

No way, real science advances step by step according to the timeline, and the birth of tempered glass means that the front-end technology has been achieved.

Who would have thought that he would leapfrog to fight monsters in this era.

Xiao Zirong didn't exaggerate too much at the beginning, he just made a piece of palm-sized glass and quenched it, and after it softened, he put it into the model that had been prepared earlier to shape it, and this was also a step to relieve stress.

After the shape is completed, the fan will be used to cool it down quickly. Of course, this fan is also driven by electricity. If it is driven by manpower, he is afraid that the purpose of cooling will not be achieved if people are exhausted.

Even in the cold room he specially selected.

However, because he has not produced an electric shock yet, he still uses electromagnetism to rotate the handle of the fan, thereby driving the blades to rotate.

The advantage of this is that it is simple and easy to do, but the disadvantage is that the speed cannot be controlled, or it cannot be increased.

Xiao Zirong didn't care, anyway, he was just experimenting now.

After the glass had completely cooled down, Xiao Zirong picked it up and took a closer look, and found that there seemed to be no big difference between tempered glass and ordinary glass from the naked eye.

If you tap it with your hands, there will be a different sound, but it is not so easy to distinguish.

After many comparisons, Xiao Zirong asked people to disperse, and directly threw the newly finished glass in his hand to the ground.

This action of his shocked everyone, thinking that the tempered glass had failed this time, so Xiao Zirong shattered the glass in a rage.

However, what they didn't know was that Xiao Zirong did this purely to see if the tempered glass was successful enough.

The safety of tempered glass is not that it will not break, there is no glass that will not break, the difference is that tempered glass will form glass beads after breaking, which will basically not cause harm to the human body.

Of course, if the glass is too thick and heavy, if the glass beads fall from the head, it will definitely be smashed.

But the problem is that this kind of situation generally rarely occurs. After the tempered glass is broken, there will be no sharp glass shards, which is enough.

After the glass in Xiao Zirong's hand fell to the ground, it was indeed different from breaking ordinary glass. Even if he squatted down and picked up those glass beads, as long as he was careful, he would not be injured.

After putting away those glass beads and looking at them carefully, Xiao Zirong breathed a sigh of relief: "Okay, the tempered glass is considered a success."

As he spoke, he had someone send the broken tempered glass to the laboratory.

Recently, Zhai Ling and the others have been busy making steam engines, and they can't take care of the tempered glass, so the entire tempered glass experiment was done by Xiao Zirong and those Liulifang workers.

Fortunately, this thing does not have any particularly high technical content. The only thing that needs to be used is the cooling system.

But mass production is not needed in the early stage, so the current cooling method can still be used. If you really want to mass produce, you must build a separate cooling room. Not only that, the cooling method must also be improved, such as air compressors Yes, there must be high-pressure nozzles.

This can only be put aside first, and the reason why Xiao Zirong sent the broken tempered glass over is mainly to teach Zhai Ling and the others a lesson, to explain to them what stress is, and by the way, to explain tempered glass. The principle of glass.

Zhai Ling and the others were indeed curious about tempered glass, and after listening to it, they all said with satisfaction: "It's better to come and follow His Highness, so we can learn more new things."

When Xiao Zirong heard what she said, he couldn't help thinking, and turned his head to ask: "If you are allowed to continue to study now, are you still willing?"

Zhai Ling and the others looked at each other, and couldn't help asking: "What does Your Highness want us to learn?"

Xiao Zirong said: "Of course it is to continue to study Gewu. You have already studied in depth in this area, and it is not appropriate to change to other research directions. You can learn more by continuing to study."

In fact, the so-called continuing education may mean continuing to learn high school knowledge, and it is great to bring some university knowledge, but for this era, such knowledge is already very profound.

Zhai Ling's eyes lit up immediately: "Your Highness, I want to learn."

At this time, a gentleman next to her asked slowly: "Your Highness, if you go to study, will you not be able to get in touch with the experiment?"

He was a bit reluctant to part with the laboratory. Learning theories could certainly expand his knowledge base, but leaving the laboratory made it difficult for him to make a choice.

He even felt that he might learn more through experiments.

However, the laboratory is not without flaws. The laboratory is based on Xiao Zirong's will. They have to study what His Royal Highness Jinling wants to do. If this continues, they may not learn as much as reading extensively.

Anyway, he could see that if the King of Jinling wanted them to continue their studies, he would definitely write his own textbooks.

Otherwise, who else in this world knows Gewu better than King Jinling?

Xiao Zirong said with a chuckle: "No, you have mastered the theoretical knowledge to a certain extent, and you will take the path of combining theory and experiment next, but this is my idea, the first batch of people who come to study will probably become The subject of the experiment, so you have to think clearly."

Zhai Ling said decisively: "Don't worry, Your Highness, he will definitely come."

Xiao Zirong nodded and said: "You can count later, and by the way, ask your sister to do the counting too. If you want to learn, send it to Jingkou."

Taoyuan City conducts primary education, and Jingkou conducts follow-up advanced education. It is also good to see that the division of labor is clear.

Xiao Zirong said while thinking about this: "Didn't you guys already make a model of the train and the track? Can it run?"

Zhai Ling nodded and said, "Yes."

This model is much smaller than the real garden train. Of course, the firebox and boiler are also much smaller. The whole train is about half the height of a person. This is convenient for experiments.

Even if King Jinling had money, he couldn't directly make finished products for experimentation, and that would be inconvenient. If there were people on the train, at the beginning, because of inexperience, the safety factor could not be guaranteed, and it would not be suitable for anyone to go on it.

If you don't take people... Do you want to follow the train below to check the data?

Moreover, according to the data given by the King of Jinling, the windows were opened at a relatively high position. Not only did they have to chase the train, but they also had to jump around while chasing to see what was going on inside.

Forget it, they are relatively lack of exercise, so they can't handle this situation.

Finally, a small train with a height of half a person was created, which is easier to control.

Xiao Zirong said very excitedly: "Come on, let it run."

The small train is made relatively simple, even without a roof, in order to make it easier to see the internal situation.

After running, Xiao Zirong observed the running situation and found that there was no problem. He felt that it would not be a big problem to directly make the finished product, so he said with satisfaction: "Okay, stop, and put it into production directly."

After he finished saying this, Zhai Ling and the others immediately changed their expressions: "It's broken, I'll just say that something seems to be missing."

Xiao Zirong looked at her strangely: "What's wrong?"

Zhai Ling's face was stiff: "This...the train...we don't know how to make it stop."

Xiao Zirong:? ? ? ?
