But at this moment, Zhang Huiguo, as an industry leader, was also shocked by this sudden lineup.
Especially Chen Weiping, Yan Dazhou, and Que Duanlin, Qing Yun added the word "front" when introducing them. He knew what this meant.
These people in front of us are all leaders in their respective fields. Their joining has undoubtedly brought strong technical support to Shin Kong Silicon Industry.
Zhang Huiguo was surprised and excited, and at the same time he had deep respect for Qing Yun's vision.
This almost includes the top leaders at the forefront of current polysilicon production process research.
It is also an integrated team of industry, academia and research.
Xiaoqing, who was in working mode, directly invited a team of experts to see the scene, saying, "Time does not wait for us, we have to race against time."
This kind of attitude towards work naturally awes people, and the old men who are engaged in scientific research are even more happy.
It’s just that the original four shareholder representatives were very embarrassed and were treated as nothing by Qing Yun.
But others are so qualified not to talk nonsense to them.
The Nanba Man and Namba Rabbits from Jiazhou looked at this scene and shook their heads helplessly. They had no choice but to take on the role of hosts and lead the remaining "miscellaneous people" there. Find a place to entertain.
Qing Yun and his team came directly to the construction site.
This place has begun to take shape, the civil engineering work has been basically completed, buildings are rising from the ground, and the connecting pipes in the middle are being laid. The enthusiasm of the workers makes Xinguang Silicon Industry... Yanhuang Silicon Industry have a bright future. hope.
Zhang Huiguo stood on the construction site, holding a thick stack of technical documents in his hand. His voice echoed on the busy construction site, and he introduced every step of improving the Siemens method to the expert team present in detail. .
His explanation is in a simple and profound way, and even people who are not familiar with the polysilicon production process can clearly understand the key points of this technical path.
“Our technical path is to improve the Siemens method, use industrial silicon as raw material, synthesize it through chlorination to generate trichlorosilane liquid, then purify it by distillation and reduce it with hydrogen to obtain polycrystalline silicon, and then process the reduction tail gas. Dry recycling involves hydrogenating silicon tetrachloride to form a closed-loop production, in which the chemical vapor deposition process of trichlorosilane in the reduction furnace is a key step in the process..."
Zhang Huiguo explained, While using the laser pointer in his hand, he pointed at the process flow chart on the display board.
Chen Weiping, Yan Dazhou, and Que Duanlin listened. They are all senior experts in the industry and are well aware of the advantages and disadvantages of the improved Siemens method.
But at this moment, I can only listen obediently.
There is no way, they are just talking on paper at the moment, and the old man in front of them is the one who is really making changes in this field in China.A great master of the Siemens method.
The first person in China to prepare polysilicon by silane method, Academician Que Duanlin, former director of the National Laboratory of Silicon Materials of Zhijiang University, nodded with conviction,
“The improved Siemens method is far safer in terms of safety. The production cost of the super-silane method is also lower than that of the silane method in the short term.”
After hearing this, everyone lamented that the improved Siemens method is far safer than the silane method, and its production cost is also lower than that of the silane method in the short term. Law, but it is a pity that the three wastes have been formed.
In particular, large amounts of chlorosilane residual liquid are difficult to handle.
Chen Weiping spoke first, with a hint of hoarseness in his voice, "Mr. Zhang, the safety of the improved Siemens method is indeed worthy of our recognition, and the cost control has been very good in the short term."
He paused and his tone turned serious, "However, the treatment of the three wastes is a big problem, especially the chlorosilane residual liquid. There are a lot of high boiling substances and impurities in the residual liquid, which will burn and explode when exposed to air.
If not handled properly, it will not only cause environmental pollution, but may also cause safety accidents."
Yan Dazhou and Que Duanlin also expressed their opinions one after another. They expressed their approval of the technical route adopted by Yanhuang Silicon Industry. , but also pointed out the risks and challenges involved.
Zhang Huiguo listened carefully to their opinions and suggestions. He knew that the opinions of these experts were crucial to the development of Shin Kong Silicon Industry.
He is a practical person, while the experts in front of him are theoretical people. Theory must be connected with practice, and practice must be guided by theory.
He nodded and agreed with everyone's views, "It is indeed a big problem, but we must look at it dialectically. I feel that this can be turned into a treasure.
To be honest , Whoever can find a way to make polysilicon production waste harmless and resourceful will be a hero of the country."
Qing Yun listened on the side, then smiled, and brought it with Chen Yiquan. Disciple Shen Jun muttered from behind,
"Brother Shen, what Mr. Zhang said about turning waste into treasure means that this chlorosilane residual liquid can actually be regarded as an intermediate, which is rich in trichlorosilane. , dichlorosilane, and silicon tetrachloride, if they can be recycled, the production cost will be greatly reduced. ”
In the previous life, this young man solved this problem.
Although his voice was small, it reached the ears of everyone present clearly.
There is no way, this young man is the helmsman of this company.
After Chen Yiquan heard Qing Yun's words, he turned around with a relieved smile on his face.
"Xiaojun, the youngest is right. If you can overcome this point, your life will not be in vain."
As for Zhang Huiguo, Chen Weiping, Yan Dazhou, and Que Duanlin The four of them looked at Qing Yun in surprise.
They originally thought that the young chairman was just rich, but the information revealed in a few words showed that this young man seemed to have high attainments in chemical engineering.
What’s more, what makes them feel strange is that Chen Yiquan’s attitude toward QingThe name of cloud.
Old demon?
Zhang Huiguo, who has lived in Xishu for many years, naturally knows what it means.
But just because he knew it, he was even more surprised. Zhang Huiguo blurted out, "The youngest?"
Chen Yiquan coughed and said, "Let me introduce you again, Qing Yun, My new disciple."
Chen Yiquan's words were very indifferent, but everyone could see the showoff like an old naughty boy on the old man's face.
Academician Que Duanlin, director of the National Laboratory of Silicon Materials at Qianzhijiang University, cursed in his heart, Damn it!
Okay, a rich and powerful disciple.
It’s a pity that it’s not our own!
“In the Siemens improved production process, we have not yet mastered some key technologies.
In the refining process, more than 70% of the polysilicon is emitted through chlorine, which not only causes high refining costs , and the environmental pollution is very serious.
Therefore, how to improve the yield of polysilicon and reduce energy consumption is the top priority for the improvement of polysilicon production process. ”
Qing Yun heard this in his heart. He also sighed helplessly.
In his previous life, the process route he participated in was called "Yongxiang Method", and it was also the third generation of improved Siemens methods.
Before rebirth, they had completed the iterative reserve of the ninth edition of Yongxiang Method. The purity of key impurity elements in high-purity crystalline silicon products reached 11 nines, and 70% of the product quality met the needs of p-type and n-type single crystals. , partially reaching the level of semiconductor electronic grade crystalline silicon, which not only solves the problem of neck jamming, but also has the ability to reverse neck jamming.
However, this is an iterative process that takes more than ten years.
If he suddenly takes out the ninth edition of Yongxiang Law at this moment, it will be like building a plasma shield in the Stone Age, which is completely empty talk.
The materials cannot keep up.
Sometimes you can climb the technology tree quickly, but sometimes you can only feel helpless.
The difference lies in the foundation.
What is at this time difference is the foundation.
For example, in the ninth edition of Yongxiang Method, most of the reduction furnace heat shields are made of ultra-low carbon stainless steel, and the key vulnerable parts use an outer cover made of a formula of nickel-gold alloy, lined with a Special new quartz ceramic.
In this way, the durability and safety of the reduction furnace are improved, and the production cost is reduced by reducing the use of gold and silver precious metals.
But unfortunately, the latter two materials have not yet come out.
It is difficult for a clever woman to make a meal without rice.
After all, there are specialties in the art industry, and he doesn't understand this aspect at all. It is a matter of metallurgy and inorganic non-metallic materials.
In human history, in fact, the Stone Age, Bronze Age, Iron Age, and then the subsequent discovery of plastics, etc., and then the application of silicon in recent decades, can be said from another perspective. , which is the progress of material development.
If the materials are not good, it cannot be said that nothing is good, but it is still laborious.
For example, America solves the overheating problem of supersonic aircraft through materials, while Lao Xiong solves it through mathematics and mechanics.
The flying tile - MiG-25, made entirely of stainless steel, has a speed of Mach 3, and even missiles cannot catch up.
This is the miracle of great strength, which fully explains what the aesthetics of violence are, and also proves that as long as the thrust is enough, the cement pier can reach supersonic speed.
Except for the difficulty in turning and making maneuvers impossible, just ask whether it is a supersonic fighter...
This kind of thinking is the victory of "systems engineering" , but not commercial.
What is before Emperor Yun is that the improved Siemens method currently led by Zhang Huiguo is still the first-generation optimized version.
The improved Siemens method has a history of more than 60 years since its invention in 1955. By the time Qingyun was reborn, industry participants have continued to optimize and improve the technology of the Siemens method. It has gone through three major Version Iterations of a dozen or so minor versions.
Fortunately, Qingyun mastered the third-generation improved Siemens method of the entire chlorine chemical system, and he personally experienced nine version changes of the Yongxiang method from 0 to 9.
The first version of thermal hydrogenation technology, the second version of silicon tetrachloride self-circulation, the third version of small-scale cold hydrogenation technology, the fourth version of large-scale cold hydrogenation...
< p>Each version is not a complete rejection of the previous generation, but a partial iterative upgrade.Otherwise it is called a replacement process.
So, based on the current conditions, in some places he can use the methods of the seventh or eighth edition, and in some places he can only use the methods of the first edition.
This is a technology combination.
Yundi was thinking rapidly in his mind about how to achieve the most optimized combination as possible under the existing technology and material conditions.
“Even though this is quartz glass, its thickness requirements are very stringent, which makes the cost quite high. The purchase price of a reduction furnace is close to 40 million.”
< p>Everyone was shocked when they heard this....Recent transcoding has been serious, which makes us more motivated and updates faster. Please use your little hands to exit the reading mode. Thank you
