Professor Qin didn't explain it to Zhang Xiaofan, which made Zhang Xiaofan's heart scratch like a hundred claws, and he couldn't wait to disassemble this machine now to see what kind of structure it was.

However, because this machine is still being used for experiments, and it doesn't seem good to do it in front of Professor Qin.

Zhang Xiaofan naturally knew that Professor Qin was not hiding because he was clumsy, I was because she was really too lazy to explain.

Zhang Xiaofan was not his student, she had no obligation to explain, and Professor Qin did not think that Zhang Xiaofan could understand these principles.

The afternoon experiment was successful, adding some defoamer that can remove water, but it was added, and the problem was easily solved.

This made Zhang Xiaofan feel that he had finally regained a little face.

But again, we encountered a very big problem.

What Zhang Xiaofan thought about at the beginning was that the price of this equipment was cheap, within 500 yuan, and then ordinary people could use it, and ordinary families could also use it.

However, the equipment in front of us now needs compressed air to drive, and everyone knows that a compressed air compressor is definitely needed.

If this is the case, there is no point in the invention of this machine, so Zhang Xiaofan feels that it should not be like this.

"Professor, please, I think you should add a simple air compression device, which can be compressed by hand, similar to a pump. ”

"In that case, the gas pressure will not be enough. ”

"If users need to buy air compressors, this is contrary to my original intention.

I definitely hope that the electrostatic spray gun we produce can be used by ordinary people, so the first price must not be high, and the second is that there is no need for other auxiliary equipment. ”

Once the cost of your powder coating tool is too high, then there will be a big problem in its promotion, and now Zhang Xiaofan no longer wants to do the factory's spray gun business.

The first is naturally reputation, it is a little smelly, although it is not to say that it stinks, but there are still many people in the industry who think that the most beautiful new material is not perfect enough, at least, many manufacturers of Zhimei electrostatic spray gun are unwilling to use it anymore.

Therefore, Zhang Xiaofan wants to do it in one step, and he doesn't want to do the middle one, which is the electrostatic powder spray gun that is currently popular on the market.

It is necessary to produce a cross-era product, of course, it may require supporting powder coatings, but the research of powder coatings has little to do with Professor Qin, mainly relying on Zhang Xiaofan and them.

"Tell me what you think, to be honest, my team wasted too much time on your project.

You have to know that I am not only your current project, but there are other projects in the pipeline, and I hope you can give us some practical advice, otherwise when those projects are ready, I will slowly withdraw some people, and then your project will be delayed again. ”

What should you say to Zhang Xiaofan? In this world, whether it is a buyer's market or a seller's market, it will always be the party that takes the initiative and has more right to speak.

Just like now, Zhang Xiaofan has a request from Professor Qin, and Professor Qin's team has very strong execution, technical strength is also very strong, and the innovation ability is slightly lacking, but Zhang Xiaofan does not think that he can find a better team than this team at present.

So now Zhang Xiaofan has all kinds of feelings in his heart, no matter how he says, he is worth billions, but it is difficult to stand up in the face of Professor Qin, people like Professor Qin, she no longer cares about how much money she can make, or how much money the person who begs him has.

So whether it is anger, annoyance, loss, or depression, Zhang Xiaofan still has to hold back, because it is Professor Qin who has the initiative now.

After cleaning up his mood, Zhang Xiaofan still had to share some of his ideas and ideas, so that he could complete the project as soon as possible.

"My thinking is this, we have mobilized about 100 master's and doctoral undergraduates on our side, and we are ready to carry out a large team of technology research and development.

Our aim is to make the powder coating a suspension in an aqueous solution that can be formed into a very homogeneous suspension with just a little compressed air ingress.

Of course, if it goes one step further, it is to be able to integrate powder coatings into an aqueous solution to form a solution similar to paint.

So my requirements for the equipment now are like this, there is a simple air compression device, and the manual one is fine.

Then I can make the suspension evenly sprayed on top of the coated object, but I would like to add a high pressure generator so that my powder coating, with an electrostatic charge, can adhere better to the coated object after the spraying is completed. ”

"In that case, the price will not be low. ”

"I don't need too high a voltage to make our powder coating particles, even if they are in an aqueous solution, have a static charge, and when the electrostatic charge of the powder coating adheres to the coated object, there will be some slight adhesion between the two.

In this way, it will not fall off easily when spraying. ”

"Okay, I'll ask them to speed up their research. ”

After returning to the lab, Professor Qin finished the task and left the lab, after all, she had other research projects that she needed to supervise.

Last week, Zhang Xiaofan discussed with a lot of technicians, most of whom are highly educated, how to make powder coatings and water form a suspension.

Finally, the combination of theory and practice came to the conclusion that the molecular weight of polyester should be reduced, so that the functional group of the sentence can be cured with the functional group of the curing agent.

In this way, the conditions of the reaction between the two will be reduced accordingly, at least the reaction temperature will be reduced to a more ideal range.

The increase in R&D personnel makes the whole laboratory seem more crowded, but this is not what Zhang Xiaofan cares about, what he cares about is the progress of the experiment and the results of R&D.

In particular, Professor Qin said that when she only had one or two months to transfer a large part of the equipment research and development personnel, Zhang Xiaofan stayed in the laboratory almost every day, just to supervise the progress of research and development, and answer questions for researchers by the way.

Although Zhang Xiaofan's basic knowledge of chemical engineering is relatively lacking compared to them, Zhang Xiaofan believes that it is difficult for this group of people to surpass themselves in the study of the essence of powder coatings.

So sometimes he would mention a few words to them, and there would definitely be no problems, and sometimes he would even come up with some formulas so that the group of researchers could find some inspiration from them. You have to find the latest chapters by yourself to read books?
