Chapter 63 Secondary sintering
Seeing that Jifu was so resolute, he asked to go to the work site as soon as he got out of the car, and Geng Xiaofang was also deeply moved. What a simple foreign expert this is, who only talks about risks and does not ask for them, which is simply the modern Bethune!
Geng Xiaofang didn't dare to slack off, so he made arrangements immediately, asking Sun Guishan to accompany the members of the porcelain support shaft device scientific and technological research project team to the industrial laboratory for a meeting, and the rest of the unrelated personnel returned to their jobs.
So surrounded by the members of the project team, Geng Xiaofang and Professor Zhu Gu Jifu walked in the middle, Sun Guishan accompanied on the side, and Shi Yicheng and Gong Zhiming, the two deputy factory directors, were slightly half a step behind, plus the members of the project team, more than a dozen people lined up in a long line in a chaotic and orderly manner, and walked towards the industrial laboratory of the special pottery factory. Hao Shuang, as the technical assistant of Sun Guishan's temporarily appointed research project team, also consciously took steps and fell at the end of the team.
The industrial laboratory of the special pottery factory is in the innermost part of the factory, and Sun Guishan led Geng Xiaofang and Professor Zhugu Jifu to go inside, and at the same time introduced the building of the factory to Zhugu Jifu.
Hao Shuang keenly noticed that when passing by the door of the art ceramics workshop, Zhu Gu Jifu's footsteps slowed down significantly. Obviously, even if he is as cunning as a pig, he can't hold back when faced with the temptation of the azure glaze making process that is close at hand.
Fortunately, the only thing that can make Professor Pig Shares Jifu unable to hold on to the art ceramics workshop is the location of the art ceramics workshop, and the subsequent workshops that Pig Stock Jifu is obviously not interested, so he did not delay any time, and the group soon came to the industrial laboratory.
The industrial laboratory of the special pottery factory is actually equivalent to a test workshop, with a very large scale, in addition to the equipment and machinery for firing special ceramics, there is also an independent small conference room.
The meeting between the project team of the special pottery factory and Professor Pig Stock Jifu, or the report meeting, was arranged in this small conference room.
After sitting down in the conference room, Sun Guishan wanted to give a detailed introduction to the current development progress of the project team on behalf of the special pottery factory, but was stopped by the wave of his hand. Then he turned his head to Geng Xiaofang and said:
"Director Geng, the general situation is that I have already listened to your deputy director Shi when I was in the capital, and it doesn't make much sense to listen to Director Sun again at this time. Why don't you ask Director Sun to take the written materials of their project team directly, and I will study them and then carry out the next step of communication, what do you think?"
"No problem!" Geng Xiaofang nodded and said to Sun Guishan: "Old Sun, do you have ready-made written materials here?"
"Yes, yes!" Sun Guishan waved his hand to the secretary of the project team and asked him to bring the materials. He originally prepared these materials for Hao Shuang, but now they are used on Pig Stocks.
The materials were quickly brought over, and Pig Stock Jifu was not polite, grabbed it in his hand and began to study it. It's just that he reads very quickly, just like a primary school student reading a villain book, flipping through the pages one by one, only occasionally pausing, pointing to a certain string of data on the material, and silently calculating in his heart.
In less than ten minutes, more than 20 pages of materials full of various data were read by Pig Stock. He casually threw the materials on the conference table, looked at Sun Guishan and said: "After reading the materials, as introduced by the deputy director of the Beijing Shi, the crux of your project team is currently stuck in the low-temperature sintering of the porcelain support shaft device, right?"
Seeing that after reading the materials, Sun Guishan was also very disappointed, but he had to put a smile on his face, nodded and replied: "Yes, it is indeed the case!"
"According to your attempt, if the alumina content reaches about 99% in the porcelain support shaft device, the sintering temperature is required to be at least 1,750 degrees Celsius, and if it is lower than 1,750 degrees Celsius, the fired support body will not be able to obtain sufficient mechanical strength to meet the requirements of production design. ”
"However, if the method of reducing the content of alumina in the support shaft is adopted, although the firing temperature can be reduced, the mechanical strength of the obtained product will be greatly reduced, right?"
"So it's a dilemma, isn't it?" asked Pig Geiff again.
Seeing that Pig Stock Jifu asked another correct nonsense, Sun Guishan was even more disappointed in his heart, "Yes, that's right!"
"Hehe," Pig Stocked Jifu laughed, and said: "So, the bystanders are clear, and the authorities are confused! To solve the problem of porcelain supports with an alumina content of more than 99 percent, it is not necessary to adopt the method of one-time sintering! Why don't you try to adopt the method of secondary sintering to verify it and see if this method can reduce the sintering temperature of the porcelain support?"
Secondary sintering?
Not only Sun Guishan, but also Gong Zhiming, Shi Yicheng and the members of the special pottery factory who are tackling key projects all feel that their eyes are bright, as if God has opened a skylight for them in a closed room.
This can't be blamed for their lack of knowledge, in fact, in this era, not only in the Chinese region, even in the world, the secondary sintering of ceramics research is too rare. Therefore, Sun Guishan, Gong Zhiming and Shi Yicheng and other project team members of these special pottery factories did not think about secondary sintering at all.
Of course, even if they think of secondary sintering, it is impossible to work hard in this direction, because for the project team members, including Sun Guishan, they have only heard of the concept of secondary sintering at most, and without the support of sufficient professional knowledge reserves and technical foundation, even if they carry out research on the direction of secondary sintering, the final result may be worse than the situation of primary sintering they have adopted so far.
But now Izuku Yoshio took the initiative to mention the secondary sintering but it is different, as a professor at Neon Yamagata University, an authority on ceramics, since Izuku Yoshio proposed the secondary sintering, he must have a very in-depth understanding of the secondary sintering, and he has a great deal of confidence that it will be like this.
Otherwise, he proposed the method of secondary sintering, but in the end he didn't have any research, didn't he slap himself in the face?
"Professor Zhu Gu," Sun Guishan looked at Zhu Gu Jifu and said sincerely: "Secondary sintering is still a blank research field in our Chinese ceramic technology community. I'm not afraid of your jokes, as the leader of the research project team, I only know the concept of secondary sintering, but I don't know exactly where to start and how to operate!"
"I see, no wonder!" Zhu Gu Jifu nodded, turned his head to Geng Xiaofang and said: "Director Geng, I am not talented, and I am lucky to have a little achievement in the secondary sintering project, which is an authority in the secondary sintering technology of the Neon Country." If Director Sun doesn't mind, I am willing to contribute my technology in secondary sintering free of charge to see if I can help them solve the problem of low-temperature sintering of porcelain supports. ”
