The expert's words fell, and other experts present nodded their heads in agreement. Indeed, in everyone’s perception, glass is a fragile product. When glass is used to make scientific research stations, the first thing everyone thinks about is whether it is really safe. And as the expert said, once such a large glass breaks, it will cause 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 also something we can't get around. Therefore, in this regard, we have also done a lot of research and improvement programs.

　　First of all, the printed glass will not be used directly, but will be tempered. This is also done for the glass's high mechanical strength, good elasticity, good thermal stability, and it is not easy to hurt people after being broken, and is not easy to explode.

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

　　 In addition, we will post a special protective film on the front and back of this double-layer laminated glass for two days. On the one hand, of course, it is to protect the glass, and on the other hand, it is naturally to block harmful radiation.

　　 And this special protective film can be adapted to change color through sunlight. That is to say, the stronger the sunlight, the darker its color, and the stronger the ultraviolet and sunlight blocked. On the contrary, if the sunlight is weaker, it will become transparent, and the sunlight will be absorbed and used as much as possible. "

　　 Where do these membranes you mentioned come from and are they transported on earth? An expert 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 moon permanent commercial scientific research station."

　　 What about the cost? The expert immediately asked.

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

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

　　 This question seems simple, but it is actually very complicated. If it is just a simple answer, it will certainly not satisfy this expert, including everyone here.

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

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

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

　　The raw materials are derived from the minerals on the surface of the moon, and the preliminary plan is to use the abundant ilmenite, copper magnesia and other metals on the moon as raw materials.

　　 The production and processing process is also carried out on the moon, mainly in two ways, one is manufactured by the direct solution casting method, and the other is manufactured by using a 3D metal printer.

　　After all the components are manufactured, they are assembled and built, and then these double-layer angled glass are installed. In order to facilitate subsequent maintenance and replacement, each square can actually be installed with two double-layer laminated glass at most, but only one is usually installed.

　　 The reason for doing this is that there is no need for it, and a double-layer laminated glass itself is safe enough. On the other hand, it is limited by weight. Although the gravitational force on the moon is relatively small, if another layer of glass is added, the overall building frame will be strengthened. In this way, the related manufacturing cost and time schedule will be greatly improved. NS.

　　 During use, if that piece of glass breaks and needs to be replaced, the astronauts and scientists only need to install another piece of glass on the square of the piece of broken glass, and then remove the piece of 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 piece of glass in front. In this way, the scientists and astronauts in the glass lunar warehouse can complete maintenance work without having to evacuate. "

Upon hearing Wu Hao’s introduction, one of the aerospace experts present here smiled and said: “This design is very good~www.readwn.com~ but I think it’s a bit cumbersome. You can completely abandon this kind of double glass. The design idea is to install a single piece of double-layer laminated glass.

　　 only need to reserve some emergency maintenance card slots. If the piece of glass is broken, a temporary glass device can be fixed to this style card 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 scheme, the overall structure is relatively simpler. The experts present nodded in agreement.

　　Wu Hao also laughed and high-five and said, "Today, this seminar is on the right track. With your suggestion, we should avoid many detours."

He smiled and praised, and then he went on to say: "We also thought about this scheme at first, but we still have some doubts about the reliability. So we also want experts to help analyze and explore in this regard to see if it is adopted. That way is more reliable."

　　 Seeing Wu Hao said this, the experts in the room started to discuss it. After hearing the analysis of some experts, Zou Huanyi, who was sitting next to Wu Hao, said with a smile: "These two designs have their own advantages and disadvantages. Your double-glazed design has the advantages of strong reliability and disadvantages. Naturally, the cost is high and the design structure is cumbersome.

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