Chapter 373 Why are you here
Naturally, Mu Bai was not going to tell them the detailed situation.

With a scientific research laboratory and a space ring with a size of 8 cubic meters, Mu Bai can definitely bring more advanced machinery and equipment to Shinhwa Display Company for assembly.

With a lot of preparations, a week later, the equipment of Shinhwa Display Company was upgraded, and the corresponding method of manufacturing 0.2 mm thick flexible glass was also taught to the technicians of the technical department bit by bit.

Because this method needs to cooperate with Mubai's upgraded machines, Mubai is not at all worried that these technicians will jump into the hands of hostile companies after learning it.Of course, even so, Mubai still signed a harsh non-employment agreement with the technicians.

"Mr. Mu, look, there is no shattering, no shattering!" On this day, in the white, dust-free and sterile advanced manufacturing workshop, a shout suddenly sounded from a corner, and in an instant, the eyes of Mu Bai and other technicians They were all attracted.

At this time, it was already the fourth day that Mubai taught them the technology of making 0.2mm glass!

In the past four days, the advanced manufacturing workshop has carried out a total of 34 experimental manufacturing, but the results are touching.

Of the 34 manufactures, a full 24 failed directly, and the rest were all defective products that were easily broken.

As we all know, glass is extremely fragile, and glass with a thickness of 0.2 mm is even more fragile. Just cleaning it into pieces can make you desperate.

But today, someone in the laboratory finally made unbroken glass, which made Mu Bai heave a sigh of relief.

"Let me see!" Mu Bai put on his laboratory gloves, and gently pinched this piece of ultra-thin glass whose edge can only be vaguely seen by the naked eye.

It is only the thickness of a banknote, and it has to be the kind of new banknote that has just come out of the banknote printing factory.

The square is two meters square, and Mu Bai shines the flashlight along the corner of the cup, so that this piece of glass can reflect less obviously in the air.

"Beautiful, perfect."

Mu Bai threw away the bright flashlight and measured the thickness with an electronic caliper.

Just exactly 0.2 mm.

"Very good, let's test its compression resistance!" Mu Bai looked at the screen in his hand with great satisfaction, and then said to the technicians: "Cut him into the size of a mobile phone, put it on the mobile phone and test it!"

Glass display screens, especially mobile phone display screens, are naturally not as thin as possible. In addition to being thin, there is another requirement!
That's stress resistance!

After all, the display screen has to be installed on the phone. If a slight bump causes the screen of the phone to crack, then buy a ghost!

Therefore, it is indispensable to conduct a compression test!
The specific operation naturally didn't require Mu Bai to do it himself. Within a few minutes, the two-meter-square glass was cut into pieces the size of a standard mobile phone screen.

Afterwards, Lu Haomin gently picked up a piece of 5.5-inch ultra-thin glass, placed it on the compression tester, and carried out the compression test at the same time as a piece of ordinary display glass just removed from the mobile phone.

The two instruments are activated, and the pressure table slowly exerts pressure on the two pieces of glass at the same time.

0.2 MPa.

Megapascal is a unit of pressure, the full name is megapascal. 1Pa refers to the pressure generated by a force of 1N uniformly pressed on an area of ​​1 square meter. It is conceivable that 1Pa is a very small pressure, and directly using Pa as the unit of measurement for pressure will also cause a lot of inconvenience to the actual calculation. Therefore, some larger units of measurement are often used, such as 1 MPa!

At this moment, at 0.2 MPa, both glasses are bent.

0.5 MPa.

The degree of curvature of the two displays began to differ. Obviously, the degree of curvature of the ultra-thin glass was significantly smaller than that of ordinary mobile phone display glass!
1 MPa.

Ordinary phone display glass bends more than ultra-thin glass!
1.5 MPa...

2 MPa...

When it was added to 2.3 MPa, there was no sign, and the display glass of an ordinary mobile phone shattered into a snowflake shape with a "click~".

But the ultra-thin display glass is still holding on!

Knowing 3 MPa, the ultra-thin display glass shattered into thousands of pieces...

"Clap clap clap..."

At some point, the entire advanced manufacturing workshop resounded with crisp applause.

Teacher Lu Haomin even burst into tears: "It is 0.4% stronger than the 30mm glass display. Am I dreaming?!"

"No dream!" Mu Bai replied loudly: "Master Lu, we did it!"

Although the display screen is just a small accessory, there are many display manufacturers in China.But basically, the display screens of mid-to-high-end mobile phones are all from foreign manufacturers, especially those from Japan.

Today, Shinhwa Display, a small display manufacturer, has achieved the world's top level at least in terms of thickness and compression resistance!

Of course, the perfect display is more than just that!
"Master Lu, don't get excited, we still have to continue the test!" Mu Bai comforted with a smile.

"That's right, there are other tests!" Lu Haomin then remembered that the stress resistance test is just one of the display screen tests, and there are others...

Tensile test, ultra-thin glass is still stronger than ordinary mobile phone display glass!

In the bending test, the ultra-thin glass is more than twice that of ordinary glass...

After each test, the excitement on Lu Haomin's face became more and more intense. Seeing his appearance, Mu Bai was really afraid that he might have a heart attack or something, that would be no fun.

"Mr. Mu, after our repeated tests, our ultra-thin display glass can proudly claim that it is stronger than the display screen of an Apple mobile phone!" In the end, Lu Haomin gave Mubai a satisfactory result.

"Well, let's make a truly perfect display screen tomorrow and see the effect!" Mu Bai said excitedly, feeling that the busyness of the past half month was not in vain.

The 0.2 mm glass produced today is only the inner screen, and a complete mobile phone display has several layers!
Early the next morning, everyone in the entire technical department gathered together again to start making a real mobile phone display.

Mu Bai didn't bother, the technology had already been handed over to them, and his presence or absence couldn't affect the result. In this case, he'd better wait for the result outside the workshop, after all, the dust-free workshop is too boring.

This waited for more than an hour.

Later, even Hu Liangyu and other company executives rushed over, ready to witness the company's new products.

"Mr. Mu, here!" More than an hour later, Lu Haomin rushed out of the workshop with an iPhone 7P in his hand. Only then did he realize that the company's management had gathered outside the workshop, such as Hu Liangyu, Chen Zhenzhen, Yu Xiaohui and others.

"Um, why are you here?" Lu Haomin asked in surprise.
