To be honest, Zhou Fangyuan doesn't know much about chemical engineering, he chose liberal arts in both worlds, and science has always been his weakness, and he never hides this. r?a? ?nw?en?ｗ?ｗ?ｗ?．?ｒ?ａ?ｎ?ｗ?ｅ?ｎa`ｃ?ｏ?ｍ?

The reason why he chose to make glass, mainly in order to master a hard currency, how the prospect of smart phones is he knows better than anyone else, for smart phones, the battery is important, the chip is important, but the screen is equally important, a good screen can make the mobile phone add a lot of color, on the contrary, it will seriously reduce the competitiveness of the product. Especially for smartphones in touch mode, a good screen is even more important than a good chip. After all, the chip is almost good, and it may only affect the performance of the smartphone, but if the screen is poor, the most characteristic touch attribute of the smartphone may be greatly reduced.

Of course, the screen is slightly worse, and it is not completely impossible, in fact, the screen of early smartphones is indeed very average, far less good than the later ones. And to be honest, let's just say tempered glass, Corning is not the only one on this planet. As an enterprise that was driven by Jobs' Apple and took off for the second time, Corning's tempered glass has indeed been widely recognized in the mobile phone market in the original time and space, but there are also some more common tempered glass manufacturers who can produce and research the tempered glass itself.

First of all, let's talk about the tempered glass itself, if it is calculated according to the Mohs hardness, only the tempered glass on the surface of the mobile phone screen, the hardness is about 6 to 7, generally closer to 6, and now the glass produced by the Beitong Glass Factory, that is, the Corning gorilla, is generally 6.5. Insert an additional sentence here, the 9H hardness of the tempered glass protective film generally advertised does not refer to the Mohs hardness, 9H is actually the hardness of the pencil core, that is, the letter H in the most commonly used HB pencil in daily life. Therefore, even if it is an inferior tempered glass film, it is generally able to meet the standard of 9h, but this kind of rich man belongs to the standard has no big effect, but it seems that its own products are not good, and all manufacturers can only voluntarily or be voluntarily marked with the 9h logo.

If you take a look at the Mohs hardness scale, and carefully compare the hardness of some of the representative items above, it will inevitably give people the illusion that there is no problem with the naked running of the mobile phone screen, after all, the hardness of such a common hard object as steel is only about 5, and ordinary glass can already cope with it. But the reality is that quartz, which has a hardness of 7, is widely found in the dust, and it is not easy to scratch the glass. Moreover, the general mobile phone screen glass will be attached to layers of coatings, including oleophobic layers, the hardness of these films is much worse than the glass itself, and many times those subtle scratches on the surface of the mobile phone are the result of their scratches.

Here is another digression, in order to enhance the anti-fingerprint ability of the glass surface of a better mobile phone, there is generally an oleophobic layer, and the existence of the oil transfer layer will allow users to be more worry-free when cleaning up stains. But even if it is a coating coating, in the face of daily use, it will gradually be exhausted in 2-3 months, such as machine spray and manual painting of some inferior tempered films, which is even more unreliable. If the daily use environment of the mobile phone is like a battlefield, the consumption speed will soar. Therefore, the mobile phone screen is not as hard as the so-called at all, and if you don't stick the film, it is still easy to hurt the screen.

The reason why tempered glass can have more strength than ordinary glass is mostly because the glass is soaked in chemical reagents such as potassium nitrate by chemical replacement, so that the potassium ions in the glass can be exchanged with the sodium ions in the glass itself. Of course, the details and technology in this area are the secrets of each manufacturer. Since it is ion exchange, the degree of exchange will naturally affect the strength of the tempered glass formed, taking Corning Gorilla as an example, an important difference in each generation of its products is the thickness of the replacement layer, and it is also because of the progress of technology, the increase in the thickness of the reaction layer, in order to achieve thinner and thinner in the case of enhanced strength.

A bunch of digressions, let's talk about the glass itself. Among the tempered glass, as a mobile phone screen, the most famous is undoubtedly the Corning gorilla, which is now the fist product of Beitong Glass Manufacturing Company.

Needless to say, Corning Gorilla is the absolute king of tempered glass for mobile phones, although in the years before Zhou Fangyuan's rebirth, major manufacturers no longer advertise their mobile phones as in the past with several generations of Corning Gorilla Glass, but its world share is still extremely high. As for those mobile phone manufacturers who have not explicitly stated, and they want to know whether their mobile phones are using Gorilla Glass, they can go directly to Corning's official website to check, they have an integration of the use of their own glass by various brands, not only the models that use Gorilla Glass, but also indicate the use of several generations of products. Because it's almost impossible to use Corning Gorilla Glass and deliberately conceal it, the information on the official website should be quite accurate.

In addition to Corning, there are several brands that are more famous and powerful.

First of all, Asahi Glass of Fuso.

This company is the second largest glass company in the world, having been founded in 1907. Asahi Glass products are a variety of glass products and semi-finished products, as well as a small number of chemical products, and are currently sold to LCD manufacturers, automobiles, lamps, construction, etc.

Its parent company is the well-known Mitsubishi Group. In 1971, he first invented the Asahi method, and has 13 float glass production lines in Fuso. The company not only has the company's shares and factories in China, Indonesia, Thailand, Vietnam, etc., but also has its subsidiaries in Europe, and the Belgian Gravel company in Europe is the company's joint-stock company. In addition to the production of flat glass, automotive glass and cathode ray tube glass, the company also produces chemical raw materials such as soda ash, electronic devices such as transistors and semiconductors, as well as ceramics and refractory materials.

"Glass" is the Japanese word for glass, which also indicates that it is a company engaged in the research of glass and related industries, and its dragon trace series products can be said to have been created specifically to fight against gorillas. The essence of Longji is aluminum silicate chemically strengthened glass, which is quite different from ordinary soda-lime glass. Its representative product is the Dragon Trace series, because the official website only indicates that there are more than 350 mobile phones that use Dragon Trace Glass, and the specific model is not marked, so the latest products are not clear in the world, and in the past products, Sony Xperiaz5, Meizu Blue Note2, Nubia Z5, Xiaomi 2, etc. are all users of previous generations of Dragon Traces. However, the mobile phone screen market is still Corning's world after all, in the Gorilla 2 generation, the dragon trail can still rely on the time difference advantage of being a little late, but after the Gorilla 3 generation, the next few generations of Asahi Glass products even the manufacturers who use them dare not clearly mark it.

Another example is Schott in Germany.

SCHOTT Group is a multinational high-tech group of companies founded in 1884. 130 years of industry experience in specialty glass, materials and advanced technology. Its main business areas include: household appliances, pharmaceuticals, electronics, optics and transportation.

The SCHOTT Glass Factory is a German factory for the manufacture of optical glass, founded in Jena in 1884 by Ernst Abbe and Otto Schoter. The original SCHOTT glass catalog contained less than fifty optical glasses. After World War II, the SCHOTT Glass Works was split into two parts: one in Jena, East Germany, and one in Mainz, West Germany. After the reunification of Germany, the two factories were merged into one company. The current Mainz Schott Glass Factory is the largest optical glass factory in the world, with more than 100 types of optical glass in its SCHOTT Glass catalog. Optical glass from SCHOTT Glass is an important material for the design and manufacture of optical lenses. Today, the Carl Zeiss Group owns the entire stake in SCHOTT Glassworks, which itself has a subsidiary in the United States and a subsidiary in China.

In terms of positioning, SCHOTT is actually the main high-end, and when its product XensationCover first came out, it was advertised on the Meizu Blue 3 that it was completely able to outperform the Corning gorillas. Someone once made a comparison between Corning, Schott and Asahi Glass. From the comparison data, it can be seen that if you have to be more serious, the Vickers hardness of Corning Gorilla up to 701 is still higher than that of Schott 681 and Asahi Glass 673, and this is the closest performance of the three products.

In fact, in addition to the above three, there are actually many other tempered glass manufacturers, such as the same from Fusang plate glass and Huaxia Luobo, especially Luobo can have a pretty good cost performance after the yield rate is improved, but in general, the screen protection glass market for high-end mobile phones is basically the world of Corning gorillas, and it is still the case until Zhou Fangyuan is reborn.

In later generations, many mobile phones have not focused on the generations of gorilla screens they are using, on the one hand, because this has gradually become the standard, everyone has begun to grasp the selling point from a deeper experience. On the other hand, after the mobile phone manufacturers use other glass, they don't even have the courage to label, so that users see the glass that is not marked with the manufacturer, and they don't even realize that they may also come from some large manufacturers, and only think about whether it is to save costs, mobile phone manufacturers have made a move in this regard. In fact, this is to listen to wronged people, especially those big manufacturers, they will not joke about their reputation because of a little petty profit.

Even if there is a difference in quality, but it is also a tempered glass produced by a large factory, it is also a bad look, and a small factory will not be able to guarantee the quality at all, I believe that no well-known manufacturers will do this kind of stupid thing, so it can only dig their own grave and break their foundation.

Of course, a monopoly is always dangerous, as far as consumers are concerned, I must still hope that these manufacturers can fight head-on with Corninggang, after all, the mobile phone glass is not afraid of scratching or falling from the real naked running, there is always a certain distance, and the gap between everyone is not too big to make up for it. Nowadays, don't look at the arrogant appearance of Beitong Glass Manufacturing Company...... In fact, in other parts of the world, the big glass manufacturers have been trying to keep Corning and NorthGlass down. It's a pity that although the idea is good, there is still a long way to go before the goal can be truly achieved.

After visiting Beitong Glass Manufacturing Company, especially after taking a turn in the laboratory and production line, Zhou Fangyuan inquired about the current production capacity and poor product rate, and the results were good, all of which met the goals he set at the beginning.

It can be seen that Professor Tan Jianying really has management talents, and the guy who was fired before is much worse in this regard, basically he does whatever Zhou Fangyuan says, and his subjective initiative is very poor. Some people may wonder, why did Zhou Fangyuan just dismiss that person when he did something to enrich his own pockets? Under normal circumstances, shouldn't he be sued in court?

It's supposed to be like this, but how to say it, the main thing is that everyone has some kinship, regardless of the distance, Zhou Fangyuan can't put down such a heavy hand.

Although he also knows that this is wrong, people are not machines, and it is impossible to operate completely according to the program, so the rules and regulations are good, but if they want to be fully implemented, there are still some unsatisfactory points. This is also helpless, different situations are treated differently, and it is impossible for Zhou Fangyuan to completely level the bowl of water. In that case, he is not an ordinary person but a saint, he is not a saint, he is just a relatively rich ordinary person, so no matter what he does, there is always some flaw, which is normal.

After seeing the situation of Beitong Glass Manufacturing Company, Zhou Fangyuan drove to the headquarters of Yuanfang Technology, a large manor.

It is not the manor before, but the manor that was rebuilt later, which is a headquarters specially built for distant technology, covering a huge area, near the Beitong Development Zone, covering an area of tens of thousands of acres, with special dormitories, activity centers, entertainment areas, etc., just like a small town.

Andy is now completely separated from the Android development team, and when he was invited to join Yuanfang Technology, Zhou Fangyuan promised that a special scientific research institution would be set up, so that Andy could use his ingenuity and talents, and the deposit would be all kinds of things he wanted to study. When the development of Android 1.0 was completed, Andy broke away from the team and assembled the Yuanfang Science and Technology Research Institute.

Zhou Fangyuan first went to the Android R&D team to take a look at the follow-up research and development work of Android, and now the Android version has been updated to version 1.3, three updates, and a lot of small problems have been solved. At present, we are working on the 2.0 version of the system, and strive to make the system more user-friendly and easy to use. At the same time, the distant i2 mobile phone is also in full swing of development, and it has almost been developed, and now the mobile phone stability test is being carried out, in terms of performance, there is no big problem, compared with the i1 mobile phone, the performance has been greatly improved, and the size has become a lot larger, which looks closer to the smartphones of later generations.

There was nothing to see in this regard, so he turned around and went to the Remote Science and Technology Research Institute, found Andy, and asked him about the progress of his recent research.

Andy is working on something very tall recently, and it can be regarded as a future development trend, that is, VR and AR technology that everyone in the future will be familiar with.
