The car arrived at the crash test site.

The crowd entered it.

The deputy director in charge of traffic safety was excited: "These are the devices in the video?"

Lu Chen smiled: "That's it, they have all been tested, and the transportation department can also test it personally, and the results will not be bad with my test results." ”

The deputy director laughed: "We don't buy these directly, in fact, our purpose is to get videos of impact tests at various speeds from you for safety publicity, and as for your airbag experiments, we can also keep them." ”

"Before this kind of safety technology becomes a formal national standard, it can generally be publicized locally, but it cannot be compulsorily promoted. ”

"Bootstrap promotion, I see. Lu Chen smiled: "Comrades who understand technology in relevant parties can look at it at will." ”

Actually, the deputy bureau in charge of transportation didn't want to come here at all.

I want to keep an eye on the material of safety propaganda in Deep Blue Technology.

"Huang Le. ”

Huang Le stepped forward: "Mr. Lu, do you have an explanation?"

"You just drove my car, the keys are still with you, and all the things in the trunk of my car have been moved for me. ”

Lu Chen made a test horse, which was put in the tail box, not in the company.

Recently, the company's personnel structure has not stabilized, and there are many people coming in and out, of course Lu Chen will not put the magic weapon that can make a lot of money in the future in the company.

Huang Le and a few employees brought in a large pile of glass products and black plates.

None of them are big, but they're heavy.

Lu Chen picked up a piece of glass with a thickness of five centimeters: "This is bulletproof glass for construction, installed on the bank counter, whether it is a sword, a sword, a halberd, a sledgehammer, a small hammer, all kinds of firearms, it is useless." ”

"Not even a sniper rifle can do devastating damage to it. ”

Li Ju took the glass plate and raised it in his hand: "The middle of this glass ......"

"I took it and named it PVB film. ”

"This kind of film has a strong adsorption force on quartz glass, including automotive bulletproof glass, explosion-proof display cabinet glass, in fact, the technology is the same, all are PVB film. ”

Lu Chen pointed to the film: "Clip it, plus the glass on both sides is made of high-strength glass, a product of this thickness, the pistol bullet can't even crack it." ”

Li Ju raised his eyebrows: "Just put a layer of PVB film in it, and it's bulletproof?"

"This PVB film can improve peel strength?"

Lu Chen shook his head: "The strength of glass remains the same, the principle is actually very simple, glass is responsible for strength, film is responsible for toughness, and the role of this full-contact interlayer is the same as that of alloy." ”

"It's just not that strong. ”

Two metals, one soft and tough, and one hard and non-malleable, can be fused proportionally to obtain a hard and ductile alloy.

This is a phenomenon that has been discovered in the scientific community for thousands of years, and it has been summed up for hundreds of years.

Bureau Li: "Try?"

Lu Chen took out the equipment used to test the car window from the crash test library and clamped the glass to the frame.

"Bureau Li, the people around you should have brought live ammunition, right? Everyone left the test site and asked the police officers to test the live ammunition, we have action cameras that can record the process. ”

Huang Yilehe, finally came to his link, and directly began to arrange the camera placement and debug the signal.

A group of people quit the lab room.

Stand in front of the monitor.

A young police officer, armed with a pistol and wearing soundproof headphones, stood ten meters from the glass.

Bureau Li: "Such a simple technique can really defend against bullets?"

To say that it is simple means that under the current technology, as long as there is similar equipment, it can be produced at any time.

In fact, there are a lot of scientific and technological patents involved.

PVB film is a technology in its own right.

There is also the technology of vacuuming to create a sandwich.

Technology for special strengthening of glass.

Lu Chen pressed the prompt light, indicating that the police officers who couldn't hear the sound had been arranged.

The police immediately opened fire.

"Bang!"

"Boom!"

After the robbery, the police immediately closed the safety and collected the gun.

Huang Yi quickly rushed to the glass with the camera.

On the monitor, the footage can be seen.

On the bulletproof glass, there is only a shallow trace.

The bullet hits in this position.

However, it only grinds the surface of the glass, and there are no pits.

Unscathed.

Li Ju raised his eyebrows: "Awesome, this technology is powerful, and it can be promoted nationwide immediately! I believe that without official organizations, major banks and companies that need security will come to the door by themselves, and how much security costs can be saved this year!"

Without bulletproof glass, someone would have to stand in the bank lobby and guard it, and it would be with live ammunition.

And with bulletproof glass, plus the ban on guns in China.

You only need to stand a security guard, and the security guard does not need to be responsible for security, just keep an eye on whether there is a thief or something.

Now the monitoring system is getting better and better, and there is no need for security guards to do this, and the current security guards are responsible for guiding the way.

Lu Chen switched the picture of the action camera.

The action camera is on the side of the glass.

Bullet into the painting, slowly moving forward.

But it's much faster than a car.

Within two seconds, the bullet touched the bulletproof glass.

The bulletproof glass shook a little in the frame.

The force of the bullet deflated itself and flew away.

Li Ju grabbed Lu Chen tightly: "It's so strong, it's better to use it directly to build a tank!"

Lu Chen had three black lines on his forehead: "Bureau Li, you think too much, the first is that the power of the police officer's pistol is too small, but this is the military version, so it is so strong, and the cost is very expensive, and the civilian version is not like this." ”

"In the civilian version, at a distance of ten meters, there will be a small crater when the pistol hits it. If it is a sand eagle or a high-powered revolver, it will have a spread wound the size of a silver dollar, and the thickness of four centimeters will form a small bump on the back. ”

"If it's an M500 hand cannon or rifle, it can be penetrated. ”

"Rifles?" "Can rifles be brought into the bank?" I can guarantee that anyone who dares to manufacture and sell rifles for sale will be caught by us before they can get the spare parts. ”

"In other words, the civilian version with a cheap cost cannot be pierced by a pistol, and it is enough!"

Li Ju: "What about the car version?"

Li Ju turned his head: "Now whether it is transporting prisoners or all kinds of people with security needs, it is very troublesome, if it can be used by car, it will be perfect!"

Lu Chen took out a piece from the glass pile: "This piece is for the car." ”

Li Ju: "It's very thin, can you block it?"

Lu Chen took it into the test site and fixed it.

Experiment again.

This time, the officer's gun made a mark the size of a saucer on it, but it didn't pierce.

Li Ju pressed the warning light, the warning light continued to flash, and the police officer continued to fire the bullet.

"Bang! bang!"

The result is the same every time I go down, there is a mark the size of a saucer, and the glass becomes an opaque white state, which is the reason why the surface structure is opaque after it is broken.

And in the middle, some powder fell off, but not in pieces of glass.

The officer fired a shot at the area that was already injured.

This time, more powder was dropped, but it was still unbroken.

The third shot, the glass broke.

Li Ju laughed: "At least two shots can be blocked in the same position, and unless the car is surrounded by troops during the march, it is impossible for the car to be concentrated in one place twice in a row!"

"Okay! Lu Chen, with this patented technology, you will be one of the top ten outstanding young people in Shudu in the coming year!"

Lu Chen laughed: "Forget about the honor, Bureau Li, can you send some police officers to assist us in conducting live-fire experiments? ”

Li Ju thought for a while: "No problem, the faster you publicize, the more orders, and the more you put into production!"

Lu Chen: "This ...... Regarding the matter of production, in fact, our Deep Blue is acquiring the glass manufacturing plant, and there are two companies in Shudu that are talking, and the production qualifications will be ...... at that time."

Li Ju: "Rest assured, there is no reason for the local government to hinder the development of enterprises with the possibility of local science and technology leaders. ”

Lu Chen: "Actually, Li Ju, you should care about the bulletproof plate, which is the most critical technology in the whole field." ”

This thing can generate billions of dollars in revenue around the world a year!

The key is that the cost is low!
