Chapter 302: Glass mirror

"This, let me think about it." Shang Wen made a reflection.

"What do you women lack?" Shang Wen asked, looking at Yingyu.

"How do I know. I am a martial arts woman." Ying Yu said.

"Oh." Shang Wen continued to look at Yingyu and nodded.

"Why are you looking at me?" Yingyu asked.

"Look at you, see you look good." Shang Wen replied.

"Hey. You're right. Even though I was born in martial arts, Yingyu is still a beauty." Yingyu happily flicked her hair and said.

"Yes." Shang Wen looked at Yingyu's face and cried out suddenly.

"Oh, I was scared to death." Yingyu complained.

"I said what do you lack most?" Shang Wen asked.

"What?" Yingyu asked rhetorically.

"Beautiful. It has to be shown. It can be seen truly." Shang Wen said.

"Aren't you talking about a mirror?" Yingyu asked.

"Yeah. You use bronze mirrors. I want to make them. It's like, water is indescribable. Anyway, let your beauty look like what I see in my eyes." Shang Wen said.

What Yingyu said unintentionally by Shangwen. Feeling a little embarrassed.

"Why, don't believe it." Shang Wen didn't look at Yingyu's expression at all.

"I believe. Of course I believe." Yingyu replied immediately. Then quickly tidy up his outfit with his hands.

"Then I will start work immediately." Shang Wen said as he took his notebook and started working.

The invention of the mirror originated in the 16th century. The cylindrical method was used to manufacture plate glass, and the tin amalgam method of using mercury to attach tin foil to the glass was invented, and the number of metal mirrors gradually decreased. In the second half of the 17th century, France invented the casting method to make flat glass and produced high-quality large glass mirrors. Mirrors and their frames are increasingly becoming interior decorations. At the end of the 18th century, a large full-length mirror was made and used on furniture. Although the tin amalgam method is harmful to the human body, it has been applied until the 19th century. In 1835, German chemist J.von Leibig invented the electroless silver plating method, which made the application of glass mirrors more popular.

What Shang Wen has to do is to use the tin amalgam method to make the mirror. But for your own safety. Shangwen decided to use a certain isolation method to make it. It is mainly operated by a certain simple mechanical arm. I don't know how to do this. Shang Wen thinks he can give it a try.

As for the raw materials of the glass. Shangwen can't think of a good way now. Instead of doing this, it's better to use another method to stimulate. That is to increase the use of glass. Encourage the glass industry to separate from other industries. Such as mirrors. Eyes, and then make some specialized instruments and equipment. Thus. It can be regarded as a disguised requirement that the upstream raw materials of glass provide increased production. In such high demand. Shang Wen felt that even if he didn't solve this problem by himself. Sooner or later someone will solve this problem.

In fact, the development of the glass industry is also very much related to the future development of close instruments such as aiming lenses. Therefore, this thing must be worked out. It is also necessary to stimulate its production with great demand.

Just when Shangwen should use some traditional methods to make glass. A man named Meng Chuang in Xianyang is experimenting with a new glass manufacturing method. This man named Meng Chuang is a very ordinary glazier. Because the materials are very limited. There are very few people who can directly make glass sheets at work. This Meng Chuang is a man who has finally gotten a job to make glass sheets. However, because of the high temperature. Makes him very comfortable with the fireside working environment. As a result, it was quickly replaced. In this life, this craft is very missed.

But this person is stubborn. You don't let me do it, I just do it. So he collected some materials quietly. Most of these are glass waste products. The glass factory has not yet realized the value of glass recycling for secondary use. Because they have a lot of pressure every day. Now the State of Qin has expanded a lot of troops at once. Both require large-scale production of telescopes. In addition, the raw materials are tight. The process is complicated, so the output has not been very high.

This person Meng Chuang also knows the status quo of the glass factory. He still knows. Qin State has a law called intellectual property protection. With this. You can get ahead by yourself. So Meng Chuang devoted himself to research.

Because I can't adapt to the working environment of high temperature. He always melts the glass first and then pours it into the mold. but. Each trial ended in failure. The special material of glass is added because of gravity. So that the poured glass is always in size and thickness. Meng Chuang believes that this is the reason why his own molds are not good enough. Or there is a problem with the material. So they experimented with wood and iron one after another. But all failed without exception.

Even Meng Chuang felt that the success of the experiment was nowhere in sight. Coupled with long working hours. There is less time available for experimentation. He can only use his rest time to do experiments. The result is still a failure. Having lost his patience, he smashed all his experimental equipment in a fit of anger. But this smash, smashed a miracle. original. He just hit a piece of tin into the pouring trough. The stove was overturned and the sink was grilled. Melt the tin block. The overturned glass water quickly flows to the sink. As a result, it was unexpected that glass of water floated on it. Seeing this scene, Meng Chuang stopped his unreasonable actions. Began to pay attention to this scene.

The glass unexpectedly floated on it. This is a big discovery. So Meng Chuang soon regrouped and began to concentrate on research.

And this one called Meng Chuang discovered is a more advanced method of manufacturing glass. Float glass. Compared to pouring. It is more suitable for large-scale production.

The forming process of float glass production is completed in a tin bath filled with protective gases such as nitrogen and hydrogen. The molten glass flows continuously from the kiln and floats on the surface of the relatively dense tin liquid. Under the action of gravity and surface tension, the glass liquid is spread and flattened on the tin liquid surface to form a smooth, hardened, and cooled upper and lower surface. After being led to the transition roller table. The rollers of the roller table rotate to pull the glass ribbon out of the tin bath and enter the annealing furnace. After annealing and cutting, a flat glass product is obtained. Compared with other forming methods, the float method has the advantages: it is suitable for high-efficiency manufacturing of high-quality flat glass, such as no corrugation, uniform thickness, flat upper and lower surfaces, and parallel to each other; the scale of the production line is not limited by the forming method, and the energy per unit product Low consumption; high utilization rate of finished products; easy to scientifically manage and realize full-line mechanization and automation, and high labor productivity; continuous operation cycle can be as long as several years, which is conducive to stable production; it can provide suitable conditions for online production of some new varieties, such as Electric float reflective glass, sprayed glass during annealing, cold end surface treatment, etc.

These are all modern production methods. But now it was discovered in an unexpected accident. I have to say it was an accident.
