Zhang Yi followed Gao Xun and several members of the technical team to the site of the sunscreen assembly workshop.

The site is responsible for the installation of the chief engineer of Huabang Machinery Company Fan Liwen, this Norman order is not small, and Wang Ruoyi added 20% more money to the equipment cost, the purpose is to rush out the required equipment as soon as possible, the company attaches great importance to it, so it is handed over to the company's chief engineer Fan Liwen to be responsible.

Seeing Gao Xun coming over with a group of people, Fan Liwen stepped forward and greeted him with a smile: "Welcome to the scene for guidance." ”

The equipment that Norman needs has been given drawings, he knows most of these equipment on the drawings, and the production process is not difficult, Wang Ruoyi's 20% expedited fee can be regarded as making Winbond make a lot of money, but there are still a few parts in the drawings Fan Liwen doesn't know, how is this possible?

These parts are extremely finely designed, and the production requirements are very high, which makes him feel that it is not simple.

Since graduating from Jiangcheng University of Technology, which ranks among the top ten in the country, he has been working in the front line, and the mechanical major of Jiangcheng University of Technology is the top three in the country.

Unexpectedly, there were equipment that he didn't know in Norman's equipment manufacturing this time, although these equipment could be manufactured according to the drawings, but this constantly teased his heart, driving him to repeatedly check the relevant information to corroborate, and the result was clueless.

The manufacture of these devices involved the company's trade secrets, and he could not inquire about them, and he did not know Norman's craftsmanship, so he could not understand how and why they were used.

In his opinion, Gao Xun who can make these devices is definitely a genius, even if he can't ask directly, but he can ask something under the side knock, so after seeing Gao Xun, he has to be more enthusiastic.

After Gao Xun shook hands with Fan Liwen, he hurriedly introduced to Zhang Yi: "Mr. Zhang, this is Fan Liwen, the chief engineer who is responsible for manufacturing and installing equipment for our Normans. ”

Fan Liwen didn't expect that the young man in front of him was actually Mr. Zhang, who was still Norman, looking at Gao Xun's respectful attitude, his position should be much higher than Gao Xun, Fan Liwen didn't dare to slack off, and greeted with a smile: "Hello Mr. Zhang, I took the liberty of not recognizing Mr. Zhang just now, forgive me." ”

Zhang Yi smiled: "It's okay, I don't look like the vice president of the company, it's not to blame Fan Gong." ”

Hearing Zhang Yi's self-deprecation, Fan Liwen said: "Mr. Zhang, you are so humorous, Mr. Zhang is a talent, and you can see that it is extraordinary at a glance." ”

"Fan Gong, you're lifting me up. Zhang Yi smiled and waved his hand, and then asked, "Fan Gong, how is the progress of the equipment installation?

Finally getting to the point, Fan Liwen's face straightened, and said: "The equipment installation started at 8 o'clock in the morning, and it is expected to take 3 days, everything goes well, and the trial production of the equipment can be carried out after 3 days." ”

Zhang Yi nodded and said, "This time is okay." ”

Fan Liwen said that as long as 3 days, it seems that a lot of manpower has to be invested, and different equipment has to be installed at the same time to be completed on schedule.

At this time, Fan Liwen said: "However, there are a few places where the design of senior engineers is too exquisite, and we have spent a lot of effort when manufacturing, and we are not fully sure when installing. ”

Fan Liwen looked at Gao Xun expectantly after speaking, this sentence was also deliberately done by him, if he didn't put it forward and installed it directly, then there would be no chance to discuss it again, so at this time he wanted to put forward the request, hoping that Gao Xun could come to the scene to have a look.

Fan Liwen actually said that the drawings were designed by Gao Xun, which frightened him, he had more than one or two contacts with Fan Liwen, Zhang Yi rarely came to the company, if Zhang Yi misunderstood that he told Fan Liwen that the drawings were designed by him, it would be troublesome.

Gao Xun immediately explained: "Fan Gong, you are mistaken, this set of technology was designed by Mr. Zhang, I don't have this ability." ”

"Oh, this is designed by Mr. Zhang?" Fan Liwen was taken aback.

He really didn't expect that such a sophisticated equipment was actually designed by Zhang Yi, although Gao Xun called him Mr. Zhang, Fan Liwen still felt that Zhang Yi was just relying on his relationship to become the vice president, either a child of a family who held shares in Norman, or had a special relationship with Wang Ruoyi, otherwise how could Zhang Yi, who was only about 20 years old, be the vice president of a large company like Norman.

Besides, the equipment was actually designed by Zhang Yi, which is even more unbelievable, it seems that Zhang Yi is a college student at most, how can he design such a device, these technologies may not be able to be done by ordinary professors.

Zhang Yi smiled faintly and asked, "Where is Fan Gong talking about?"

Fan Liwen still found it difficult to accept it in his heart, but he finally calmed down, since it was designed by Zhang Yi, he might as well let him take a look and see if Zhang Yi could say something, and the result would be clear at a glance.

He took out a roll of drawings from the long packaging bag, unfolded it and placed it on the table, pointed to a few of them and said, "Mr. Zhang, that's what I'm talking about." ”

Zhang Yi saw it and knew that these places had indeed been redesigned by him, and since the 21st century, with the development of technology, the requirements for equipment in technology application have become higher and higher.

All technical solutions must rely on mechanical equipment to produce, and the advanced nature of the process has higher requirements for the precision of the equipment.

Zhang Yi said: "These places are designed and completed by me according to the process requirements, these parts are just what I need to use this technology, you specialize in mechanical equipment, and it is normal that you do not understand the process." ”

These parts, to be clear, are of little use to Fan Liwen, and they are not classified things, so it doesn't hurt to tell him.

Zhang Yi turned to Gao Xun again and said, "Dr. Gao, why do you say nanoparticles are so difficult to produce?"

Hearing Zhang Yi's question, Gao Xun said without thinking: "Of course, it is because nanoparticles are easy to agglomerate, and after agglomeration, they lose their effect, so naturally they cannot be produced." ”

Zhang Yi nodded and said: "Yes, this is the most headache encountered in the process of studying nanoparticles, the preparation of ordinary sunscreen, after the base material is homogenized, we can add the sunscreen." ”

"The nanoparticles themselves have a tendency to spontaneously agglomerate, and if the compatibility in our paste base is poor, then this kind of agglomeration is very obvious and rapid, and the sunscreen after agglomeration loses its sunscreen effect. ”

Gao Xun nodded and said, "Yes, so this is also an important factor restricting the development of nanotechnology, which is also very."

The main reason why nanoparticles have not been widely used in sunscreen cosmetics for a long time. ”

Zhang Yi said: "Therefore, to achieve nano-level sunscreen, in the addition process, as much as possible to make it evenly dispersed and stable, so it needs to have a special surface treatment process. ”

Hearing this, Fan Liwen also understood a little, and he guessed on the side: "Could it be that this equipment is used for surface treatment?"
