The God of Technology Begins with the Principal of a Technical School

Due to the specific experimental procedures, the corresponding product was synthesized in more than two hours.

Wearing a mask and gloves, Li Mo carefully sealed the unknown black powder and took it under an electron microscope to observe.

After searching for less than three minutes, I found the twelve-sided silicon oxide molecule described by Xu Li.

After seeing this, Li Mo was a little excited to apply.

Unexpectedly, this compound molecule actually existed, so he immediately began to order several researchers.

"Get ready for vapor deposition!"

Vapor phase deposition, abbreviated as CVD, refers to the process of introducing the vapor containing gaseous reagents or liquid reagents that constitute the film elements and other gases required for the reaction into the reaction chamber, and chemically reacting on the surface of the substrate to form a film.

Many thin films in many large-scale integrated circuits are often prepared by vapor deposition.

It is also mainly divided into thermal chemical vapor deposition, low pressure chemical vapor deposition and plasma chemical vapor deposition. The corresponding experimental equipment and methods of these three types are also different.

However, in order to successfully prepare thin films by vapor deposition, three necessary preparation conditions need to be met.

First, at the deposition temperature, the reactants have sufficient vapor pressure and can be introduced into the reaction chamber at an appropriate speed;

Secondly, in addition to forming solid film materials, the reaction products must be volatile;

Finally, the deposited film and base material must have sufficiently low vapor pressure.

All three are indispensable.

Li Mo soon began to transfer the black powder to the vapor deposition equipment and turn on the equipment.

And during this period of time, we can only wait.

An hour later, the vapor deposition was completed.

Li Mo took the deposited film out of the box, and a translucent film with a radius of 60 cm was placed on the test stand and presented to everyone.

Looking at this film, several researchers were very curious.

What is the use of this film?

However, this one alone was not enough. They then took out five films from other vapor deposition equipment.

After processing and cleaning, Li Mo and others took it under an electron microscope to observe it.

"Principal, these films are all embedded with silicon dodecaoxide. Look, this is the test report."

Li Mo handed the detection report to Xu Li.

"Very good, let's prepare for the filtration experiment."

This polygonal nano-silicon oxide film also has the molecular structure of graphene embedded in it. According to the knowledge recorded in my mind, it can filter out more than 99% of impurities except water molecules, which plays a great role in sewage purification.

.

Everyone began to install the membrane on the corresponding separation and filtration equipment, and took some sewage and began to inject it.

Soon, a very strange phenomenon occurred.

Through the glass, you can see that after the originally turbid sewage entered the equipment, it underwent obvious changes after passing through the membrane.

I saw that the originally turbid end began to settle, and some dark impurities appeared.

Below, there is pure water that is transparent and without any impurities.

The upper and lower ends show a clear distinction.

"Wow! So amazing!"

The researchers exclaimed.

Upon seeing this, Li Mo quickly used testing equipment to observe, and was surprised to find that except for water molecules, there were basically no other impurities inside.

This test result amazed many researchers present.

"This membrane is so powerful! Can this cup of sewage turn directly into drinkable pure water?"

"Not yet, it needs to be sterilized before it can become drinking water."

"If this were applied to household water filters, wouldn't it defeat most of the water purifiers on the market?"

Xu Li smiled after hearing this.

Indeed, if he uses this kind of film to create his own independent water purifier brand product, it is estimated that those merchants selling water purifiers will cry for their fathers and mothers.

At present, the domestic water purifier market is not as systematic and complete as refrigerators and washing machines. It is still in a state of chaos and winner takes all, but the competition is becoming increasingly fierce.

Moreover, the profit margins of such products vary greatly, but the consumer market demand is also quite large.

Because more and more Chinese people are paying attention to water health and are worried that it is unsafe to use tap water directly as drinking water, they will buy those water purifiers and install them in the kitchen.

Water purifier products are also divided into several categories. In addition to the direct drinking water dispensers commonly used in companies or schools, there are also the following types.

The first is the kind of water purifier that hangs on the wall in the kitchen. Nowadays, almost every household has this type of water purifier. It is easy to install and does not occupy an area. However, the purification effect is average and it is easy to form scale. The filter element needs to be cleaned or replaced regularly.

The second is the pre-filter, which is suitable for use in household appliances that use water and plays a protective role. However, it is in the primary filtration and cannot accurately filter fine particles, so the purification effect is not very good.

Next is the RO reverse osmosis water purifier, which has excellent purification effect and can be drunk directly. However, the wastewater ratio is large and it needs to be powered on from time to time.

There is also a water filter jug ​​that students like to use. This type of water filter is simple to operate and small in size, but it cannot be drunk directly. The purification effect is not very good, and the filter element needs to be replaced regularly.

Of course there are other categories.

In fact, the working principle of the water purifier is very simple. It basically uses a layer-by-layer filtration method. It uses a progressive structure to filter out impurities and heavy metals and other pollutants in the water layer by layer.

, thereby achieving the effect of purifying water quality.

The ones that can achieve outstanding results are Biotech, Garnet, Smith, and Philips... They are all ranked in the top ten in the world, and there are also top ten brands in China, except for Medi and Qingyuan.

In addition, there is the new rice.

Recently, Rebus has also entered into this type of home products, and the sales results and reputation achieved are pretty good.

But Xu Li would not create such a water purifier brand, because in order to establish such a brand, in addition to technology, there is also a lot of investment in stores and after-sales, which also requires a lot of money.

He prefers to be a film supplier. Wouldn't it be faster to make money while lying down?

"After the experiment is completed, go and tell Wang Dalong."

Xu Li thought to himself.

Then, Xu Li directed everyone to continue the experiment.

He wants to use this film to produce other substances. This substance can be used as a catalyst to quickly decompose organic matter in waste or garbage into hydrogen, methane, oxygen, etc., and at the same time degrade harmful substances such as plastics into can

Other materials for recycling.

If this kind of material can be mass-produced, then he can start the pilot project from the school to build a clean and green campus, saving a lot of operating costs. At the same time, he can also use these valuable materials and sell them, so that he can

It has added several sources of income to schools and companies.

Isn’t it beautiful?
