After the expert finished speaking, other experts present nodded in agreement. Indeed, in everyone’s perception, glass is a fragile product. When using glass to build a scientific research station, the first thing everyone thinks about is whether it is really safe. And as this expert said, once such a large piece of glass breaks, it will have a devastating blow to the astronauts and scientists living in the scientific research station, so we have to be cautious.

"You are right to worry. This is indeed a huge drawback of this kind of glass, and it is something we cannot get around. Therefore, we have also done a lot of research and improvement plans in this regard.

First of all, the printed glass will not be used directly, but will be tempered. This is also done to ensure that the glass has high mechanical strength, good elasticity, good thermal stability, and is less likely to hurt people or self-explode after breaking.

In addition to tempering, we will also process this piece of glass. First of all, the glass used to build the scientific research station is not a single layer, but a double layer of laminated glass. That is to say, two pieces of two-centimeter-thick glass are combined into one piece, and the middle is filled with a special polymer interlayer film specially developed for the harsh environment of the moon. In addition to strengthening the overall strength of the double-layer laminated glass, this polymer interlayer film also And it has certain barrier sealing and anti-radiation effects. Even if both layers of glass are broken, they can be sealed by this polymer interlayer film and supported until replacement.

In addition, we will put special protective films on the front and back of this double-layer laminated glass. On the one hand, it is of course to protect the glass, and on the other hand, it is of course to block the radiation of harmful rays.

And this special protective film can adaptively change color through sunlight. In other words, the stronger the sunlight, the darker the color, and the stronger the UV and sunlight blocked. On the contrary, if the sunlight is relatively weak, it will become transparent, absorbing and utilizing sunlight as much as possible. "

Where did these membranes you speak of come from, and were they transported on earth? Some experts asked.

Wu Hao nodded and replied: "Yes, this kind of membrane is very light and does not take up space, so it is very convenient to transport. Even one transportation can support the construction and use of the entire permanent commercial scientific research station on the moon."

What about the cost? The expert then asked.

Wu Hao said with a smile: "The manufacturing cost of this kind of film is relatively cheap, mainly due to the early R\u0026D investment. As for the production and manufacturing of this kind of glass, except for related equipment, there is basically no cost. The main raw materials are They can all be obtained from the moon, so the cost is very cheap.”

I have a question. An old expert adjusted his glasses, and then asked Wu Hao: "How to try out this kind of double-layer laminated glass and how to build it?"

This question seems simple, but it is actually very complicated. If you just give a simple answer, it will definitely not satisfy this expert and everyone here.

Then Wu Hao slid the transparent tablet under his hand, and a bird's-eye view rendering of the transparent warehouse of the scientific research station appeared on the big screen. This is a single glass building on a huge hemispherical dome. The surface of the hemispherical glass building is divided by numerous grids, with a piece of glass installed inside each grid.

Through the transparent glass, you can see what's going on inside. In addition to the living and working areas for astronauts and scientists, there is also a lunar vertical farm in the center area, where various crops are grown.

"This is our preliminary design of a single glass lunar cabin for the lunar scientific research station. It has a diameter of 32 meters and a height of 17 meters. The main frame of the entire building is made of metal alloy materials.

The raw materials come from minerals on the lunar surface. It is initially planned to use metals such as ilmenite, copper ore, aluminum magnesium ore, which are abundant on the moon, as raw materials.

The production and processing process is also carried out on the moon. There are two main methods. One is to use direct dissolution casting method for manufacturing, and the other is to use 3D metal printer for manufacturing.

After all the components are manufactured, they are assembled and then installed. In order to facilitate subsequent maintenance and replacement, each square can actually install up to two pieces of double-layer laminated glass, but only one piece is usually installed.

The reason for this is that on the one hand, there is no need for this, and a piece of double-layer laminated glass itself is safe enough. On the other hand, it is limited by weight. Although the gravity on the moon is relatively small, if an additional layer of glass is added, the overall building frame will be strengthened, which will greatly increase the related manufacturing costs and time schedule. .

During use, if that piece of glass breaks and needs to be replaced, astronauts and scientists only need to install another piece of glass on the square of the broken glass, and then remove the broken glass.

Of course, for convenience and beauty, you can also install a new piece of glass after removing the broken glass, and then remove the temporary glass in front. In this way, scientists and astronauts in the glass lunar cabin can complete maintenance work without evacuating. "

After hearing Wu Hao's introduction, an aerospace expert present smiled and said: "This design is very good, look for Shuyuan www.zhaoshuyuａ.com. However, I think it is a bit cumbersome, and we can completely abandon this double block." The design concept of glass is just to install a single piece of double-layer laminated glass.

Just reserve some card slots for emergency repairs. If the piece of glass is broken, a temporary glass device can be fixed on the style slot. After the repair and replacement are completed, the temporary glass device can be easily removed. In this way, wouldn't it be simpler? "

Yes, compared to the previous plan, the overall structure is relatively simple. The experts present nodded in agreement.

Wu Hao also laughed and high-fived: "Today's seminar was on the right track. With your suggestion, we will avoid many detours."

He smiled and praised, and then he continued: "We also thought about this plan at first, but we still have some doubts about its reliability. So I would like experts in this regard to help analyze and discuss it to see if it is adopted. That way is more reliable.”

Seeing Wu Hao say this, the experts present all started talking. Zou Huanyi, who was sitting next to Wu Hao. After hearing the analysis of some experts, Mr. Zou immediately said with a smile: "Both designs have their own advantages and disadvantages. The advantage of your previous double-layer glass design is high reliability, but the disadvantage is Naturally, the cost is high and the design structure is cumbersome.

As for this emergency temporary glass repair device, it has a simple structure and low cost, but its reliability is definitely not as good as your solution. "
