Lu Chen watched the people from the logistics department lift up the first piece of glass, and pointed to the glass: "This is an experiment made by me, the front windshield, but its material is bulletproof glass." ”

"The principle is the same, except that the PVB film inside is better and the glass is more delicately processed. ”

"Everyone knows that there is a phenomenon called Rupert's tears. ”

Rupert's tears melt glass into a liquid state and then drip into water to form tadpole-shaped glass.

Because the surface is the first to condense, and the inside is still molten glass, the glass beads will shrink after solidification.

The inside shrinks, and the surface is pulled.

causes a change in surface tension.

Rupert's Tear, the size of an ordinary glass bead, can withstand a hydraulic press and shatter bullets that hit it!

"In industry, Rupert's tears are not very useful, but we can borrow the principle of condensation to treat glass and improve its hardness. ”

Lu Chen walked to the glass and pinched both sides of the glass with his hands: "Can such a thin glass withstand the attack of bullets?"

"Officer Blue, please!"

The beautiful police officer appeared again, and the barrage was also speculating whether he could withstand it:

"I think that since Lu Chen took it out for experimentation, it should be able to withstand bullets. ”

"But such a thin glass, even if it can withstand bullets, it should be able to move up to one or two clicks, right?"

Lu Chen looked at the barrage displayed on the big screen at the scene, and smiled without saying a word.

One or two clicks?

Pistol?

Lu Chen: "Officer Lan, I'll leave it to you here." After saying that, he put on sound-isolating headphones.

Those who are close to the scene are wearing soundproof headphones, and those who are far away are busy with live broadcasts.

Officer Blue holds a gun in both hands, clenches 54, inspire!

"Bang!"

"Bang bang bang!"

A few shots in a row.

The windshield rests on the simulated car frame.

Wherever the bullets were hit, structural damage was produced about the size of a fist.

Or the surface has formed a crushing zone that is opaque.

But the film and a layer of glass behind the film.

Unscathed.

Officer Blue took aim again at the place where he had fired a shot before.

"Bang!"

This time, the glass behind the film also shattered, but the windshield was not penetrated at all.

"Officer Blue, please take a break, action camera replay. ”

The screen begins to play back.

The bullet is clearly seen under the deceleration of the moving picture.

Slowly and leisurely hit the windshield.

However, without going in even the slightest, it lost momentum in situ and almost stuck to the glass surface.

Then bounce slowly and leisurely.

At the same time, at the place where the shot was taken, some fine powder flew out of the glass.

The glass that didn't fly out also began to shatter.

The vibration traveled for almost a fist before it stopped.

The glass in this area has shattered, but it has not fallen.

It is still tightly glued to the PVB film.

The situation was the same for the next few shots.

In the end, Officer Lan re-fired a shot from his gun, which hit the shattered glass, but it knocked a lot of glass ballast.

However, it still failed to damage the entire piece of glass.

The bullets bounced off, and most of the ballast remained glued to the film.

Judging from the back lens, there are already cracks on the back.

But there was still no breakdown.

Barrage:

"I'll go, it's really bulletproof!"

"In sports, it is a fool's dream to concentrate on the same place twice in a row. ”

"As long as the bullet hits different parts of the bulletproof glass and does not cause the bulletproof glass to fall off or break through, it can be said that the bulletproof ability is excellent!"

"Amazing, this invention will soon be adopted in many places, right?"

The live camera cuts back to the main shot.

Lu Chen: "There are many series of bulletproof glass, in addition to bulletproof glass for cars, there are also bulletproof glass for construction. ”

At the scene, several employees were cleaning the ground.

Lu Chen: "Let's take a break and start the test of bulletproof glass for construction immediately, in addition, there will be a rifle test of these glasses in the later stage, don't miss it." ”

Before I knew it, another three hours had passed in the live broadcast time, and it was already six o'clock in the afternoon.

Lu Chen ate a throat lozenge handed over by Yang Rui.

"No, the company wants to recruit some professionals, I will speak alone, and my throat will smoke!"

Lu Chen sat next to Yang Shiyu while eating sugar.

Yang Shiyu can directly see the live broadcast venue here, and there are several monitors next to it.

It should be said that the director should be sitting here.

However, there is no director in the live broadcast industry, only a director, so this position belongs to Lu Chen, but it is empty.

"Give you water. ”

Lu Chen picked up the water: "Thank you, are you watching the barrage here?"

"Hahaha, there are so many talents online. ”

Lu Chen looked at the computer screen, and swiped a strip on it: "Lu Chen has given us time to eat bubble noodles again." ”

"The takeaway phone can't get through, and it's very sad. ”

Takeaway?Takeaway?Takeaway?Lu Chen thought of this and shook his head.

In this world, there is no ecological environment and living soil for takeaway software.

Because there is no full-screen existence in this world.

It should be said that the screen of the mobile phone in this world is also a touch screen, but the style is relatively rough and deviates.

It's like another space-time, and the Nokia era has gone down the path of a fool's machine.

A fool machine and a smart machine, it sounds like a big difference.

In fact, it is not the case, it is born after the emergence of smartphones and the improvement of the system.

In fact, their role is the same.

It's just that because the hardware is different, the system is different.

Depending on the system, the software that can be equipped is different.

The touchscreen phones of this world are not so sensitive, and they are at the point where fingers can just hype.

This also makes the touch screen unrealistic and slightly more difficult to operate.

In another space-time mobile phone APP, the tight operation button arrangement is beyond the reach of mobile phones in this world.

For example, the QQ and micro messages in this world are very large, so there are many fewer functions added.

But on the whole, the online circle of this world is similar to that of previous lives.

There is not much software missing, mainly the kind of software that requires repeated operations to achieve the goal.

For example, to order takeout, you need to select several stores, look at a variety of different dishes, then click on the selection, then submit the order, pay, and view the route.

At the same time, merchants and riders need to see new orders and make it easy to operate when they are busy.

The low sensitivity of the screen creates a devastating barrier to entry for this type of software.

Can't cross it.

Electronic equipment? Lu Chen thought that he had a new idea here.

The scientific and technological products of this world are relatively rough, for example, the mouse is still a mechanical mouse, and the optical mouse has not been born.

Mechanical mice are very expensive to achieve the same sensitivity and accuracy as mechanical mice.

The roughness of this kind of scientific and technological products has great oppression and damage to the sense of experience and comfort.

Studying a phone screen?

Lu Chen shook his head, it is not very difficult, but it is useless to only improve the sensitivity of the screen, and accordingly, the entire accessories of the mobile phone must be improved, otherwise it will not be able to support the screen with high sensitivity at all.

It's like buttoning down the console of a high-speed rail and pressing it on a car.

Counterproductive.

However, the system mall, can it be exchanged for things directly?

If you can redeem it, it will save you a lot of trouble.

After all, it is also very profitable to do mobile phone hardware upstream.

Lu Chen sat here in a daze, but he was actually searching the mall.

Retrieved the side, the mall does not have the exchange of this kind of thing.

Perhaps only the big bundle is likely to have these things.

But if the package is a mobile phone?

The last big package was ten Ferrari Enzo plus a fully equipped proving ground!

Yang Rui hurriedly stepped forward: "Boss, it's almost time." ”

Lu Chen forked off the system mall and walked to the live broadcast camera: "Have you rested well, everyone, the experiment continues!"
