Chapter 242 Liquid Crystal Glass Substrates
"Turn around."

Under Zhang Xingchen's order, the entire turntable began to spin, spinning so fast that even Zhang Xingchen couldn't see clearly, the speed was too fast.

Zhang Xingchen estimated that it took about 10 minutes before the entire turntable stopped.

At this time, there are three words written on the position where the pointer stops: cold-proof clothing.

A winter jacket had already appeared on the screen, and Zhang Xingchen nodded curiously.

The cold-proof clothing instantly entered Zhang Xingchen's mind as a stream of clear water, and this clear stream was the knowledge of how to make cold-proof clothes.

"It turns out that it can protect against the low temperature of minus one hundred. It is a good dress."

Zhang Xingchen murmured.

"Minus [-] degrees, I don't think we can reach such a low temperature on this planet..." Zhang Xingchen murmured.

Next, Zhang Xingchen's goal is the liquid crystal glass substrate, which is an indispensable part for making screens, and the evaporation machine is used to coat it.

To tell the truth, enterprises in our country also produce liquid crystal glass substrates, but the quality cannot meet the production standards abroad, that is, the quality cannot keep up.

So many key parts are actually produced abroad, and most of what we make are non-critical parts and some parts with low added value.

The things that really make money are still made by foreign people, and most of the profits are also given to foreign countries.

We are a big manufacturing country and produce a lot of things, but we are not yet a strong manufacturing country. Some things cannot be manufactured by ourselves, or the quality of our own manufacturing is not as good as that made abroad.

The goal of Xingchen Company is to turn our country from a manufacturing powerhouse into a manufacturing powerhouse.

Is this difficult?

For other companies, this is simply an impossible task, as difficult as heaven, but for Xingchen Company, it doesn't seem to be that difficult.

At present, 50.00% of the world's sales of liquid crystal glass substrates are occupied by an American company called Corning.

Let me emphasize again that what I am talking about here is the entire world market, not a certain small area.

But there is still 50.00%, unfortunately, the remaining 50.00% is basically occupied by island country companies, of which the island country’s Asahi Glass Company occupies 20.00% of the global market. Tranquility occupies 19.00% of the global market.

The combined share of companies in island countries is 40.00%[-]!

What kind of concept is this? The market for liquid crystal glass substrates in the world is basically divided by the United States and island countries, while other countries only occupy one percent.

Isn't this a monopoly?

Not to mention TV screens and computer screens, just talking about mobile phone screens, one screen needs two LCD glass substrates, we can think about how big the market for LCD glass substrates is.

Moreover, mobile phones are consumables. Basically, they will be replaced after three or four years of use. Now there are a few who have used their mobile phones for more than five years. If there are any, then I did not say what I just said.

I want to ask, how many of my own mobile phones can be used for more than ten years.

I have seen laptops that have been used for more than ten years, but what about mobile phones?
Haven't seen it in reality yet.

As for liquid crystal glass substrates, there are generally three manufacturing methods, the first is the overflow melting method, the second is the orifice upward drawing method, and the third is the floating method.

Just now we have said that two liquid crystal glass substrates are needed to make a screen. These two liquid crystal glass substrates have different functions and are used as the bottom glass substrate and color filter respectively.

Because of the different functions, there is still a little difference between the two liquid crystal glass substrates.

The three methods we mentioned above actually produce liquid crystal glass substrates with their own characteristics, and the liquid crystal glass substrates manufactured by different methods are also somewhat different.

Here... Zhang Xingchen chose the orifice up-drawing method when manufacturing color filters, and used the overflow melting method when manufacturing low-layer glass substrates.

In this way, the most suitable overflow melting method can be produced, and the screen produced will be better.

The raw material of the overflow melting method is the same as that of making chips, that is, the silica sand we usually see in it.

Many people can't imagine that silica sand is actually the raw material for chip manufacturing and overflow melting method. What seems inconspicuous is so important.

To create an overflow fusion method, the first thing to do is to mix the raw materials together.

Of course, the raw materials include silica sand, but not only silica sand, but also other things, such as lime, quartz stone, marble and so on.

The robot acts as Zhang Xingchen's assistant by Zhang Xingchen's side. Zhang Xingchen lets the robot do all the hard work. As a big boss and a great scientist, Zhang Xingchen will naturally not do this kind of work. matter.

Moreover, robots are very suitable for this kind of work, and they can do it without any mistakes.

If something does go wrong, it must be something wrong with the programming of the robot.

Moreover, the robot can also help you keep secrets, and there will be no leaks, which is beneficial and harmless.

This step is the feeding. These raw materials are processed in batches at high temperature until they are processed into a melt with low viscosity and uniform texture.

After reaching this point, only the first step has been completed.

The next step is the second step, which is sheet forming.

This step is very critical. Whether the final color of the liquid crystal glass substrate is good or not can basically be determined in this step.

So don't go wrong.

The current melt is a liquid, what we need to do is to pass the liquid into the tin bed, but we must control the amount of entry, and it must not be too much, otherwise it will affect the quality.

When the specified level is reached, the pouring should be stopped at this time, and when necessary, the shift should be used to block to prevent the melt from further entering the tin bed.

The melt that enters the tin bed will cool down quickly, and then the melt will be introduced again. After a total of three times, the glass panel will be starred, and the rest is to carry out the next step on the panel that has been manufactured.

Here it needs to be quenched, then annealed, and we get a very large glass panel, which is then cut to the size we want according to our requirements.

What we are talking about here is the orifice upward method, because the melt is continuously introduced above the tin bed, so it is called the orifice upward method.

Another liquid crystal glass substrate is being produced by the overflow melting method.

The assembly line has never stopped, and these assembly lines are all manufactured by Zhang Xingchen himself based on the technology he obtained from the super black technology system.

All are unique.
