With the progress of society, bullet-proof glass has slowly entered the real life. Bulletproof glass is a composite material obtained by special processing of glass (or plexiglass) and high-quality engineering plastics. It is usually a transparent material and usually includes The polycarbonate layer is sandwiched between ordinary glass layers. Is it good to use bulletproof glass countertops ? What is the structure of bulletproof glass? Just go with Xiaobian to understand.
Bulletproof glass table is good
Bullet-proof anti-theft glass consists of several pieces of transparent float glass with different thicknesses and multi-sheets of PVB film. The total thickness is generally more than 20mm. The total thickness of the required bullet-proof glass table can reach more than 50mm. The metal impact is also only Can break the glass and can not penetrate, so play a bullet-proof anti-theft effect.
Bulletproof glass countertops are composite materials obtained by special processing of glass (or plexiglass) and high-quality engineering plastics. They are usually transparent materials, such as PVB/polycarbonate thermoplastics, which have the appearance of ordinary glass and The act of transmitting light provides certain protection for the shooting of small arms.
The bulletproof glass produced by different manufacturers varies. Basically, however, a layer of polycarbonate is sandwiched between ordinary glass layers. This process is called lamination. In this process, a material similar to ordinary glass but thicker than ordinary glass is formed. Bullets fired on bullet-proof glass will break through the outer layer of glass, but the layer of polycarbonate glass material can absorb the energy of the bullet, thus preventing it from penetrating the inner layer of glass. These large pieces of bullet-proof glass have been used for public purposes during World War II, and are usually as thick as 10.0 cm to 12.0 cm, and they are extremely heavy.
A bullet-proof glass countertop is a kind of special glass with high safety that can withstand intact or non-penetrating damage without breaking the frame under certain equivalent bomb explosion.
Bulletproof glass advantages and disadvantages
Advantages: A strong and durable, you can hammer the hammer, the pork ribs will not break the pork feet, the two basin holes are pre-made, not on the scene, there is no cutting and grinding dust. Soy sauce on the three sides will not permeate, the table will not change color, and the glassware will be easy to clean. The new Wuyang bullet-proof glass countertop is good, durable and durable. The bulletproof glass table in Hunan accounted for a certain share. You can find the "New Wuyang bullet-proof glass countertop" after the purchase. Disadvantages: that is, glass countertops can not be as seamless as quartz stone countertops, splicing gaps or layers; the other is not on-site cutting, changing size, stove, basin hole must be pre-opened, the production cycle is relatively long.
Bulletproof glass structure composition
Bulletproof glass is actually made by bonding multiple pieces of glass or high-strength organic sheets together with a transparent glue material. Generally have the following three-tier structure:
1 bearing layer: This layer first to withstand the impact of rupture, generally using a large thickness, high-strength glass, can destroy the warhead or change the shape of the warhead, making it lose its ability to move forward.
2 transition layer: generally use organic glue materials, strong adhesion, good light resistance, can absorb some of the impact energy, change the direction of the bullet. A very strong and transparent chemical film is sandwiched in the laminated glass. This not only can effectively prevent gunshot shooting, but also has the ability to resist surge surge, explosion resistance, shock resistance, and no crack after impact.
3 safety protection layer: This layer uses high-strength glass or high-strength transparent organic materials, has good flexibility and toughness, can absorb most of the impact energy, and ensure that bullets can not pass through this layer bullet-proof glass, the most important performance indicator is Bulletproof ability. The index of bulletproof ability is measured in two aspects. On the one hand, it is the ability of security protection, and on the other hand, the ability of the firearm to be protected.
Bulletproof glass effect and structural factors
The bulletproof effect is related to the following structural factors of bulletproof glass:
1) The total thickness of bulletproof glass is proportional to the bulletproof effect;
2) The film thickness in the bullet-proof glass structure is related to the bulletproof effect, such as the bulletproof effect of the 1.52mm film is better than the bulletproof glass using the 0.76mm film;
3) The glass strength is related to the bulletproof effect. The bulletproof glass made of tempered glass has better bulletproof effect than bulletproof glass made of ordinary glass. The safety effect of bullet-proof glass is mainly determined by two criteria. The first is that bullets must not penetrate. If bullets pass through, they lose their protective effect. Second, they cannot drop the glass on the back, because the broken splashes may also hurt. personal.
Editor's summary: The relevant information on the structure of bulletproof glass countertops and bulletproof glass was introduced here for everyone. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.

Double Handles Bathroom Faucet
1. Copper body: As far as the faucet is concerned, copper has long become the preferred material, mainly because the antibacterial effect of copper media has long been recognized by authoritative laboratories. Most high-end bathroom brands use copper as the body of the faucet, and the elimination of other materials has become an inevitable trend.
2. Electroplating: The quality of the electroplating surface is the most intuitive expression of the quality of the faucet. The surface plating is mainly nickel and chromium, so that it achieves a smooth and bright effect. Good quality faucets will undergo many tests, such as salt spray test, water test test, gas test test, etc., to ensure the durability of the faucet. After high-precision plating faucet, durability is basic, and more importantly, its surface gloss is good and comfortable to handle. Some high-grade faucets have other different treatment techniques, such as stainless steel and satin.
3. Filter screen: In areas where the water quality is not superior, the installation of the filter screen can reduce and filter impurities, and at the same time prevent the possible damage caused by impurities to the ceramic valve core. There are two installation locations for the filter: the water inlet and the spout.
4. Rotation angle: can rotate 180 degrees to make the work convenient, and can rotate 360 degrees is only meaningful for a sink placed in the center of the house.
5. Can lengthen the shower head: increase the effective radius, increase more functional possibilities, and the sink and container can be filled faster. In order not to make unpleasant noises, metal pipes should be avoided as much as possible.
6. Water pipe length: Experience shows that 50 cm long pipes are enough, and pipes of 70 cm or more can also be bought on the market.
7. Anti-calcification system: calcium will be deposited in both the shower head and the automatic cleaning system, and the same situation will occur on the faucet, where silicon will accumulate. The integrated air cleaner has an anti-calcification system that prevents calcification of the device internally.
8. Anti-backflow system: This system prevents dirty water from being sucked into the clean water pipe, which is composed of layers of materials. Devices equipped with an anti-backflow system will display the DVGM pass mark on the surface of the package.
9. Material: Stainless steel is hygienic and environmentally friendly. Chromium devices are easy to care for and harmless to people, but other elements need to be added to the manufacturing process. Therefore, it must be paid attention to what materials the equipment is made of, and not all countries have such high standards as Germany.
10. Durability: The anti-calcification system can protect the equipment from the danger of water leakage and handle damage.
