For these people who stood up impulsively and pointed at themselves, Zhang Xiaofan expressed his understanding very much.

But understanding is understanding, but it doesn't give them a chance to have a seizure.

"Don't worry, why are you in a hurry? The same is a mobile phone, can a 300 yuan mobile phone be the same as a 30,000 yuan mobile phone?

Everyone is not a child, since I dare to say that this technology is epoch-making technology, then you should believe me, and you will never say anything.

I'm also a face-saving person. ”

Hearing Zhang Xiaofan say this, it was really quiet below, and although the person who stood up was still indignant, he still sat down honestly.

However, the noisy sound has not decreased, after all, everyone sits together in twos and threes, and there are always some people who have opinions and will complain to each other.

"Superhydrophobic technology!"

This technology is actually very unfamiliar to many of you here.

Especially for those managers of powder coating companies, they basically have no access to superhydrophobic technology, and they have never even heard of it.

But some, the production enterprises that use powder coatings or paint coatings, they may have heard of it, and some of them have even applied it.

So the discussion was louder, and compared to most people who were at a loss, some people scoffed at Zhang Xiaofan, because they had indeed heard of this technology and were using it.

Although it is not the superhydrophobic technology mentioned by Zhang Xiaofan, it can be regarded as a hydrophobic technology, and it has been used in many fields.

"This technology is currently in the paint industry, and semi-finished products can already be seen.

Why is it a semi-finished product because some paint companies, I mean paint and coating companies, they advertise the superhydrophobic technology, which is actually a lie.

To deceive the layman, their superhydrophobic technology is not really superhydrophobic technology.

It is a superhydrophobic technology that is reduced, and I won't say much about the specifics, so you can learn about it yourself.

At present, this technology has no application in powder coating, and I don't need to talk about the technical difficulties, I think everyone here should also know very well.

Because many of you haven't heard of this technology, what does that mean?

This shows that this technology is difficult to apply to powder coatings, but our company has developed it.

This is unique in the world. ”

"Why, does this gentleman have any opinions?"

Zhang Xiaofan saw a person in the first row in front of him standing up straight, and then raised his hand, as if he had something to say.

"Mr. Zhang, can you talk about the application scope of this technology first?

And what exactly is superhydrophobic technology?

After all, I've just seen that there are a lot of industry managers coming here, just to have an expectation of what you call epoch-making technology.

I especially hope to use my own industry and improve the quality of my products, but everyone's time is very precious, and I hope that Zhang can always talk less about some topics that are not related to it. ”

Zhang Xiaofan is actually quite embarrassed, I just brag about how awesome my photography skills are, isn't this allowed?

So many famous companies in the world hold press conferences, they will brag about their companies, their products, and how powerful their technology is.

Zhang Xiaofan sighed in his heart, it is still a matter of fame, if Zhimei New Materials is now like BMW or Fruit Company, then as long as there is a press conference, others will listen quietly below, like a pilgrimage.

What is like now? It made Zhang Xiaofan feel very uncomfortable.

"It's obvious that you're wasting everyone's time, and I'm ready to explain this technology in detail next, so I thought you'd have any constructive suggestions!

Please sit down first, and I'll explain the technology first. ”

The face of the person who had just stood up was a little hot, but because it itself might have been exposed to more sunlight, it was a little darker than the average person, and others could not see it, and he was already blushing.

Glared at Zhang Xiaofan covertly, but because it was too far away, Zhang Xiaofan didn't see it, so he sat down curtly.

"Superhydrophobic, as the name suggests, means that water droplets cannot spread on top of the layer, and will directly merge into water droplets and roll off.

And the angle is very small.

Rolling contact angle, our experimental data is 5 degrees, and the critical degree of superhydrophobicity is 10 degrees. ”

The angle here refers to the angle between the plate surface and the horizontal plane.

You can't say too much about the contact angle on such an occasion, because many people won't be able to react for a while.

It is relatively simple to say that the rolling contact angle is the angle required for the water droplets to roll down.

"In fact, there are a lot of superhydrophobic surfaces in our nature.

Haven't we heard a poem!

Out of the mud but not stained, clear ripples but not demons.

This poem is very clear that there is a layer of superhydrophobic material on the surface of the lotus, which is why he is closest to the essence of the silt without staining!

When it comes to the applications of superhydrophobic surfaces, that's very, very wide.

However, due to the limitations of the current technology, the scope of this material has to be reduced a lot. ”

In fact, superhydrophobicity is only a broad concept, it is not only superhydrophobic, it can also have a very strong superphobic effect on dust and oil.

"When we developed this technology, we wanted to apply it to automotive powder coatings, and I think you can imagine that.

Let's not talk about the rain, let's talk about the dust, if the dust falls on the surface of this paint, that is, when it falls on the car.

With a little wind or rain, we can easily sweep the dust off the surface of the car.

Can you imagine whether the application of this technology to the surface of the car will bring a new round of growth to the automotive industry?

Let's talk about furniture, we all know that there are wood and iron furniture, no matter what kind of material, as far as possible without contact with water, for his service life will be greatly improved.

Due to its superhydrophobic surface, dust falls on top of the furniture and is not very easy to clean.

We are talking about fitness equipment, there will definitely be sweat when exercising, and sweat will have a certain corrosiveness for any kind of material.

But if this surface is superhydrophobic, sweat falling on the gym equipment will immediately slide to the ground due to gravity, and will not stay on the surface of the gym equipment, not even a little bit.

Speaking of oil pipelines, I think if superhydrophobic technology is applied to the coating of the inner wall of the pipeline, can it reduce the deposition of petroleum solids, then the inner wall of the pipeline will be very clean?

This reduces the cleaning of the inner wall of the pipeline and improves the efficiency of the entire oil transportation. "You have to find the latest chapters by yourself when you read books?
