The development of science and technology has made modern people more and more lazy.

If you can ride a car, you will never ride, and if you can ride, you will never walk.

Of course, there are some people who are still lazy in the arrangement of the itinerary, but they are willing to take the time to run up to 10 kilometers and 20 kilometers.

People are getting lazier and lazier, which actually means that technology is becoming more and more developed.

The more advanced science and technology are, the more people's requirements for quality of life will definitely be constantly improving.

Moreover, people's awareness of environmental protection and energy saving has been continuously enhanced, so that the surface coating with self-cleaning function has been rapidly developed.

The formula that Zhang Xiaofan provided to the technical department some time ago is about superhydrophobic coatings.

One of the most important properties of superhydrophobic coatings is:

Self-cleaning surface.

This is a very big killing weapon, Zhang Xiaofan was still going to nest for a while, especially when his market share was very high, and then he took out this technology, then he said that the effect embodied was not comparable now.

But now the Flying Leopard Coating is pressing step by step, so Zhang Xiaofan has to take out this technology.

Self-cleaning surface, in fact, when there are pollutants or dust on the surface of the paint, these dust can fall off on their own under the action of gravity or external force of rain or wind.

In fact, many of the utensils now belong to the self-cleaning surface is very high.

However, the price of these appliances is very high.

Superhydrophobic self-cleaning surfaces are used in a wide range of applications, such as exterior window glass in buildings, windshields in automobiles, bathroom mirrors, spectacle lenses, and glass covers for measuring instruments.

If these surfaces have a superhydrophobic self-cleaning function, imagine that if there are water droplets on them, whether it is rain or humid air, they will quickly slide off, making the surface highly transparent.

This can not only bring great convenience to work efficiency, or provide higher possibilities for vehicle driving safety.

Therefore, superhydrophobic coatings are the application of superhydrophobic materials to coatings.

You can imagine that if our car uses superhydrophobic paint, then it can really achieve a year without washing the car, of course, you can't be too sloppy in this driving place, after passing through the mud pool, it will definitely not work.

If you're just running around the city, you'll definitely not need to wash your car for a year.

This superhydrophobic coating is Zhang Xiaofan's killer feature, once this coating is applied to the surface of the car on a large scale, it is conceivable that it will be popular all over the world.

If it were not for the tight closure of the flying leopard coating this time, Zhang Xiaofan estimated that this set of technology would have to wait for a while.

In this way, you can take advantage of the current never-waxing technology and make a round of money later. In the use of this superhydrophobic paint, make another round of money.

While this is a good idea, it's often the way things are, and the plan doesn't keep up with the change.

Zhang Xiaofan came to the office mainly to see how their experiment went.

"Mr. Zhang"

"Tell me, what technical requirements do you meet?"

When it comes to superhydrophobic surfaces, he actually has a relatively shallow technical indicator.

When the water droplets form a contact angle on the surface of the material, explain the contact angle a little.

If you want to say the definition, the contact angle refers to the tangent line of the gas-liquid interface made at the intersection of gas-liquid and solid-solid phases, and the angle between the boundary between liquid and solid-liquid.

In nature, we usually find that when water droplets fall on a certain surface, water droplets are formed, and we can observe the shape of this water droplet.

For example, when the water droplets fall on the lotus leaf, the water droplet is relatively round, if you use a fast camera to capture this phenomenon, you will find that the contact surface between the entire lotus leaf surface and the water droplets is very small.

This indicates that lotus leaves are hydrophobic.

Another example is a piece of wood that has not undergone any treatment, and if there is water dripping on the surface of the wood, the wood will quickly absorb the water.

This moisture cannot be spread on the surface of the wood at all, let alone have any contact angles.

This material is a hydrophilic material.

When the contact angle is less than 90 degrees, we will consider the material to be hydrophilic.

If the contact angle is greater than 90 degrees, the material is hydrophobic. When the contact angle is greater than 150 degrees, we consider the material to be superhydrophobic.

Of course, it cannot be said that the superhydrophobic powder coating developed by Zhimei New Materials this time is a deeper level of development on the basis of the formula.

In fact, there are very few intrinsically superhydrophobic materials in nature, even if they are very flat cermets or polymers, if they are not treated, it is difficult to reach the water contact angle of more than 150 degrees, or even 125 degrees.

For metals, some of the iron and aluminum plates we usually see can be treated with fluorine to obtain a contact angle of about 150 degrees, thus becoming superhydrophobic materials.

Just like the non-stick pans we usually see, they are actually coated with a layer of superhydrophobic paint.

This kind of coating is PTFE, and PTFE is what we commonly call the "plastic king".

This material, with its high lubrication and non-stickiness, is arguably the best of all plastics.

PTFE can be used as wax powder in powder coating, which is something that increases hardness, and the surface hardness of powder coating with PTFE will be very high, and it is easy to scratch by hand.

Now Liu Qi in front of Zhang Xiaofan is very excited.

"Mr. Zhang, we have basically achieved a water contact angle of 155 degrees, and basically completed the task you assigned.

However, we also wanted to increase the surface density of the paint so that the water contact angle of the entire paint was larger.

We found that the never-waxing technology and the superhydrophobic technology have a very big thing in common, and even the principle of the two is very similar.

After the two technologies are added, we find that there is actually a facilitating relationship between the two, but after the two technologies are added, there is some matting phenomenon.

We are working on this technical difficulty. ”

This point is what Zhang Xiaofan did not expect, superhydrophobic technology may have a matting effect on the surface of the coating, but it will greatly promote the surface density of the entire coating.

There is a gap between molecules, how to reduce the gap between molecules?

This makes the entire surface more compact, which makes the entire coating more stable and then exhibits stronger hydrophobic properties.

"We don't have much time left, and I hope you will perfect this technique as soon as possible.

This will be another shining brand played by our company, and I hope you can solve this problem in half a month. ”

"It should be possible, we are moving very fast. "You have to find the latest chapters by yourself when you read books?
