The world is getting more complex and global day by day. The population is higher than ever before. The fact that all these people have very serious opportunities also brings some question marks to mind. Not all people have to have good intentions. There is a very high risk that a person intends to harm and engage in dangerous behavior. In this case, it is of great importance to take security measures to the highest level. Especially people who are in decision-making positions need advanced security systems much more. Today's advanced security technologies include bulletproof glass. Bulletproof glasses can act as an invisible shield. Thanks to this feature, it is carefully preferred in various locations.
Contrast of Glass and Solidity
We see examples of glassware everywhere in our daily lives. Every building, every house is surrounded by glass. Glasses are like our windows to the world. We could have had very strange building and city designs in a windowless layout.
However, one of the most distinctive features of glass is its brittleness. Due to the nature of the glass material, it can easily break. Even when we hit the glass with a hard object, we can break the glass. In fact, the glass can break even when it falls to the ground with its own weight. It just has to fall at the right angle.
How can such a sensitive material be made so strong that it is not even bulletproof? What change could make lenses extremely durable? How can glass become so reliable that it saves our lives?
How is Bulletproof Glass Produced?
In fact, the glasses used in bulletproof glasses are normal glasses. However, the secret lies in the material placed between a pair of glasses. If you take two glasses and put polycarbonate between them, and then join them together, you get bulletproof glass. When you use polycarbonate between glass layers, some incredible results come out. Polycarbonate is not a material that reduces light transmission. Therefore, we do not experience any loss in terms of vision. However, this substance gives the glass serious durability. A durability that can stop even a fast, hard and sharp object like lead.
What is Polycarbonate?
Bulletproof glass is based on polycarbonate. Polycarbonate is a type of plastic. It has a very rigid structure. One of its most important features is that it is transparent. So we can think that polycarbonate is quite clever about what it does and what it doesn't.
Placing polycarbonate between layers of glass is called lamination. As a result of this process, the thickness of the glass increases. The thickness of bulletproof glass is approximately 7 - 7.5 mm. Of course, this thickness difference returns to us as security.
How Does Bulletproof Glass Work?
We've seen that polycarbonate and the lamination process can make a glass bulletproof. So how does polycarbonate achieve this? How can it exhibit the ability to hold lead even though it is transparent?
When you shoot a gun at bulletproof glass, the incoming bullet breaks the outer layer of glass. However, the laminated layers inside are waiting for their turn to come. Laminated sheets consist of bonds that are very tight. This structure absorbs the energy of lead. So the bullet cannot continue on its way. He has to bounce off the window. However, light can pass through the bonds of the laminated floors. So we can see the back of the laminated sheet.
Single Sided Bulletproof Glasses
We often think that bulletproof glasses are bulletproof from both sides. But the truth of the matter is not exactly like that. Today, at the point where polycarbonate technology has come, it has become possible to produce single-sided bullet-proof glasses. These glasses offer us an important opportunity. Let's say a security vehicle has one-sided bulletproof glass. In this case, bulletproof glass can allow fire from inside the car to the outside, while protecting the people inside the car from outside attacks. Thus, while providing security, counter-attack becomes possible. A slightly different way is preferred to produce single-sided lead-permeable glass. These glasses have a fragile layer on the outside of the glass. A flexible layer is placed on the inside of the glass. When glass lamination is performed in this way, one-sided lead-permeable glass is obtained.
Where is Polycarbonate Used?
In fact, polycarbonate appears at various points in our daily lives without us being aware of it. It is possible to give examples of the use of polycarbonate from many different industries. Eyeglass lenses are one of the areas where polycarbonate is preferred. It is important to get a quality vision and to produce durable products in eyeglass lenses. Breaking eyeglasses poses a very serious risk to our eyes. Polycarbonate is used in the production of eyeglass lenses, as no eyeglass company wants to use lenses that will remove the eyes of their customers. polycarbonate security a substance that is used extensively in the field. Police shields are also produced from polycarbonate material, which is quite durable. Bulletproof glass is also used in these shields. It becomes possible to protect the security forces while providing visibility. We used to give a lot of place to CDs in our daily lives. With the development of technology, our CD habits have also undergone a great change. Although we use these products much less now, polycarbonate is also used in CD production. Car headlights are another area where polycarbonate is used.
Cars are structures that need to reach high speeds. The headlights, on the other hand, are located at a very low level and should consist of glass. If any stone coming from the road damages the headlight, the night vision of the driver is badly affected. In this case, the journey can become quite dangerous. In order to avoid such risks, the production of headlights is also made using polycarbonate. There are countless substances in the universe that we have discovered and have not yet discovered. The intelligence we have allows us to use even just one substance for multiple purposes. We are making inventions that seem impossible through polycarbonate. Many different sectors have the opportunity to develop themselves. This story of polycarbonate gives us hope to be able to effectively use many different materials in a similar way in the future.
