Zhang Xiaofan did not clear his throat, nor did he pretend to groan, but directly began to explain the purpose of his visit.

"Professor Qin, then I'll get straight to the point. ”

Zhang Xiaofan did not wait for Professor Qin's response.

"This time, I asked Feng Shao to cooperate with the world's top engineering professors like Professor Qin, and I now want to develop a powder coating equipment that is cheap and can be used by ordinary people. ”

"Wait!"

When Zhang Xiaofan mentioned powder coating, please ask him to interrupt him directly.

"With all due respect, I have basically never been exposed to powder coatings, and I have very little exposure to paints.

So to be honest, I don't know if I can help you?"

Zhang Xiaofan shook his head gently, powder coating is rarely accessible to anyone, even if it is the world's top engineering master, it may not necessarily come into contact with powder coating.

It may be because powder coating is relatively niche, but the output of powder coating is increasing year by year, although it is not as good as paint coating, but according to the current trend, it will be able to exceed one day.

This is a lot of paint people are very sure, they all think that this is the trend, but in fact, how it will be, no one knows this!

"In fact, the principle of the electrostatic spray gun equipment we currently use is actually very simple.

In a word, it is to use the principle that opposites attract, like-sexes.

Powder coating spraying will definitely have paint and the coated object, the coated object is grounded and summarized as the positive electrode, and the powder coating makes the powder particles produce a negative charge through the electrostatic spray gun, so the powder coating can adhere to the coated object.

At present, the structure of almost all electrostatic spray guns on the market is relatively simple, basically composed of a high-pressure generator, a gun body, and a powder delivery system control system.

I have a couple of pictures here, you can take a look at them a little. ”

Professor Qin took the mobile phone in Zhang Xiaofan's hand and kept looking back at the pictures, but he didn't show any curiosity, and after reading it, he just shook his head gently.

"The structure is quite simple, you don't have to look for me, although it fits my profession very well, but you should know what I want. ”

Zhang Xiaofan showed an embarrassed look, the principle of the spray gun on the market today is very simple, and the structure is also very simple, in fact, many research institutions can develop it casually.

But what Zhang Xiaofan wants is not this kind of electrostatic spray gun that can be developed casually, if you need this kind of spray gun, there are things on the market, as long as you spend a little money, which one can't be bought?

"Professor Qin, there are many types of spray guns on the market, but the price is generally more than 2,000 yuan, and the requirements for the spraying environment are very high.

When it comes to paint, a teenager can apply it with a brush, but powder paint cannot.

It is not enough to spray powder coating with electrostatic spray gun, but also need supporting dust collection equipment and powder spraying table.

I want to design an electrostatic powder spray gun, preferably within the price of 500, and then there is no need for dust collection equipment, and there is no need for a spray table.

Because I think powder coating can enter thousands of households, not as it is now, only the main body of the company can use it. ”

If many powder coating colleagues hear this, they will definitely be very surprised or I roll my eyes at Zhang Xiaofan, and of course someone will give an admiring look.

Many people may think that Zhang Xiaofan's idea is very crazy, let powder coating into thousands of households, which is something that many people who have done a lifetime of technology powder coating dare not think.

Liquid coatings are always easier to use than powder coatings, which is why people are familiar with liquid coatings nowadays.

Paint, water-based paint, real stone paint, exterior wall paint, wood paint, etc., etc., it is all in a liquid state, and more than 80% of people will think of a bucket of paint when they hear it, and 20% of people don't even bother to think about it.

However, Professor Qin didn't react, as if he had just heard a very ordinary thing, and he was not moved by Zhang Xiaofan's so-called ambition.

"It's good to have ideas, but do you have any ideas?"

Zhang Xiaofan suddenly got stuck, if you have ideas, do you still need to find top professors like you?

Zhang Xiaofan just knows that he wants very different equipment, what are the final requirements, how is this developed? In fact, where is it, what is the process, and what is the result?

Zhang Xiaofan didn't know anything about these, these were not what Zhang Xiaofan was good at, but Zhang Xiaofan really didn't have anything to be good at.

If we talk about technology, although these technologies come from him, it is not he who develops them.

Just like now, Zhang Xiaofan clearly knows that if he wants to develop such a device, he must need a lot of technical cooperation.

But Zhang Xiaofan doesn't have any good ideas in his heart now, and Zhang Xiaofan envisions electrostatic spraying equipment that ordinary people can use.

Which one can be sprayed on the coated object after being loaded into the equipment after getting the powder coating, but basically no dust will be generated in the middle, and the powder coating utilization rate is more than 99% at one time.

Although opposites attract, it requires a huge voltage, but if the voltage is too large, it is still a question whether the wires in ordinary people's homes can be loaded, and the voltage is too high, and safety is also a problem.

Therefore, the requirements for the equipment are even stronger.

Or another way of thinking, work powder coating technology, and develop a powder coating that can produce great adsorption power with a very small amount of electricity.

In this way, the equipment requirements will be very small, and many powder equipment manufacturers may be able to develop them.

But Zhang Xiaofan did not have even a little inspiration for these powder coating technologies, he did not know what kind of powder coating would produce great adsorption force under a very small amount of electricity, and future knowledge did not give him a little hint.

Therefore, now Zhang Xiaofan is vigorously recruiting all kinds of undergraduates, master's students, and doctoral students, in order to rely on their ingenuity and intelligence, and to be able to develop a powder coating that Zhang Xiaofan does not have in his memory.

In fact, scientific contingency is greater than inevitability, so Zhang Xiaofan believes that vigorously investing manpower and material resources will always yield something.

Even if he can't complete the tasks he assigned, even if he goes on according to his ideas and doesn't develop anything, all kinds of by-product scientific products will come into being.

This is how the Never Waxing technique came out, which Zhang Xiaofan did not expect. You have to find the latest chapters by yourself to read books?
