In the afternoon, the drizzle unknowingly became heavier.
Compared with the midsummer rainstorm, this rainfall is nothing. It's just late autumn, the cold brought by the heavy rain makes people shiver.
Fortunately, Ye Qing prepared a lot of long clothes for himself, and he didn't feel cold at the moment.
In the civil air defense project, Ye Qing and the Master Craftsman walked through a long and wide passage and entered a large equipment room that was obviously modernized and modified.
The old steel blast door here was transformed into an automatic blast door that needed to be swiped to enter. Now the door is open, and a sci-fi corridor leading to the Red Queen computer room in Resident Evil appeared in front of the two.
Swiping the card again entered the glass door, and the air vortex like a blower blew up on both sides. A synthetic electronic sound echoed in the corridor made of glass and metal.
Of course, it's not a warning, and there are no high-energy lasers sweeping over.
"Verification passed. Please put the electronic products you carry with you into the electromagnetic shielding storage box and change your dust-free clothes."
Two metal boxes popped up on both sides of the corridor, opening the glass door of a locker room full of anti-static dust-free clothes of different sizes.
Put down the mobile phone and key and went to the locker room to change into a fitting dust-free suit. Ye Qing stepped into the 10,000-level dust-free workshop that was cleaner than the baby's skin.
This is the newly planned product research and development department. This morning, the instruments ordered by the research and development department have just arrived. Ye Qing came here to visit.
Any company that wants to maintain long-term product competitiveness must continuously invest a lot of money in research and development of new technologies and products.
With the Monster Factory, Ye Qing has an advantage that no company can match in terms of new technology. However, in terms of new products and convenient functions, he has to rely on himself.
For this reason, Ye Qing ordered a batch of cutting-edge industrial experiment instruments that few people were willing to use. After a short wait, these cutting-edge industrial experiment instruments were officially settled in the newly built dust-free operation room of Monster Heavy Industries.
The 10,000-level dust-free workshop refers to the dust particles greater than or equal to 0.5 microns per cubic meter in the air, no more than 10,000.
This sounds like a lot, but in the outdoor natural environment, even in the beautiful grassland with clean air, the particle content per square meter can only be calculated by weight. Using the quantity is not responsible for statistics.
Walking in, Ye Qing felt as if he had walked into a pure white world.
The equipment was pure white, the ceiling was pure white, and the walls were pure white as well. Only the floor was different from the color of the employees' dust-proof suits.
Transmission electron scanning microscope, thermomechanical analyzer, material stress detector, isotope mass spectrometer …
The employees of the product research and development department were accompanying the technicians sent by the instrument manufacturers to carefully learn the debugging and daily maintenance steps of the instruments.
In the previous recruitment, the product research and development department had the highest requirement for a diploma.
At present, among the 40 new employees who had joined the department, more than 20 of them had a master's degree and 7 had a doctorate. A quarter of them were from Ye Qing's alma mater, while the rest were top students from various universities.
These employees had been following their mentors in the laboratory all year round. Not only were their hands-on skills strong, but they were also very familiar with the various instruments in the laboratory.
The transmission electron scanning microscope had just been adjusted. A master's graduate from Zhongyun University volunteered to enter the closed ventilation operation room next door to test and polish the samples.
The observation samples of different microscopes had different ways of making them.
The sample of the projection electron scanning microscope, unlike the ordinary optical microscope that the students were exposed to, needed to be coated with a layer of transparent glass. It needed to be in the shape of a metal sheet.
The master's student had followed his mentor to study the process of bainite steel.
Bainite steel was widely used in aviation, vehicles, ships, as well as the materials of pressure vessels and high-pressure pipelines. If you wanted to study bainite steel, the first step was to observe the characteristics of bainite steel.
The characteristics were commonly known as magnifying the structure, from its appearance to the magnification of the crystal structure, so that the crystal lines of bainite could be observed with the naked eye.
When Ye Qing entered, the employee was in the ventilation operation room, dipping an eraser in grinding liquid and wiping mechanically back and forth on a stamped metal sheet that was almost invisible to the naked eye.
"Boss ~" The employee stopped wiping and stood up to greet Ye Qing with some restraint.
Because no suitable candidate was found for the time being, Ye Qing was temporarily the manager of the product research and development department. Ye Qing had held a meeting with them before, so the new employees here could recognize Ye Qing.
"Tang Bo, you … are you going to rely on an eraser to wipe the sample to a thickness of 500 nanometers?" Ye Qing also had an impression of the senior from his alma mater. Seeing this, his eyes widened.
That's right!
The sample thickness of the electron scanning microscope was only a few hundred nanometers.
This thickness was about one-thousandth of a hair, and only those special machine tools that were often only responsible for one process could cut it.
"Grind out the approximate thickness, and then test it with a laser thickness gauge at any time." Tang Bo scratched his head, "This method was taught by my senior. He said that the sample sheet is processed with a high-precision machine tool, and the metals wear each other. It is easy to incorporate other metals into it and affect the observation effect."
"With manual polishing, as long as the correct method is mastered, the time will not be slower than the machine tool processing. And the sample produced only has a single bainite structure, which is very conducive to observation. "
Ye Qing gave him a thumbs up, indicating that he should continue to work hard.
Manual polishing could indeed slowly grind the thin metal sheet to that thickness. The eraser was only ground on a large piece of thin metal sheet, and finally cut out a suitable sample shape under an optical microscope.
There was an extremely advanced laser thickness gauge to constantly test the thickness. As long as one had patience, in theory, ordinary people could also grind out a thickness of 500 nanometers. Even if it was worn out, it didn't matter. The sample only needed a small round piece 3 millimeters long, and one could be cut from anywhere.
Of course, this was only in theory. Ordinary people would have a mania if they were to grind out 50,000 nanometers, let alone 500 nanometers.
Seeing Tang Bo grind happily, Ye Qing realized that he had recruited a talent, a talent with extraordinary patience.
"Boss, the instruments you have here are too advanced. You even have an atomic probe." Tang Bo grinded more and more vigorously, "This is like the Garden of Eden for industrial dogs. Only the chemistry laboratory in Zhongyun University can be used. If we industrial dogs want to do an electrical scanning characterization, we have to look at the face of the chemistry laboratory."
"Compared to the eliminated products from ten years ago, boss, the gap between a pheasant and a phoenix is like the gap between a pheasant. As for the atomic probe, I guess that only those professors have seen it. "
"Then do a good job. Any equipment and instruments, as long as they can be purchased, the price is never a problem."
After a few words of encouragement, Ye Qing turned around and went to visit other places.
Ye Qing had just walked to the front of the isotope mass spectrometer when a man wearing a dust-free suit came in from the dust removal channel and kept shouting, "Boss ~ Boss."
The man was the sales manager, Hong Tao. After seeing Ye Qing, he trotted over: "Boss, I just called you and couldn't get through. Cai Chenning from Zhongyun University called and said he wanted to ask you for a favor. "
"He introduced himself as your university teacher, so I hurried here to find you."
"Well, he is indeed my teacher." Ye Qing nodded, walked to the dust removal channel, took out the phone, and dialed Professor Cai Chenning's number.
