With the development of automobile and mechanical properties, the speed becomes more and more fast, fierce wind and flying debris into a very serious problem in the driver’s face. In order to reduce the trouble, the twenty’s of last century, various automobile manufacturers with a piece of glass in the car. These initial windshield by flat glass hand cut, but unfortunately when the glass broken, sharp splinters of flat glass will be broken into a large dangerous, and injury to the occupant, which do not meet the windshield installation for safety purpose.
The use of the automobile glass are mainly two types of material, laminated glass and tempered glass. Laminated glass is two layers of glass with a layer of gelatinous membrane overlap between, cannot split completely in the event of damage fracture and diffusion. Even if the occurrence of serious impact, relying on intermediate adhesive film can also be damaged under the circumstances to ensure glass does not fall off and some scattered, remained relatively integrity. Because of this characteristic, in order to ensure the implementation and safety driver set aside to complete in the presence of impact, laminated glass is provided in the front windshield.
Toughened glass in damaged, can spread rapidly into numerous small particles, and it is easy to fall off, in the critical moment can easily escape, and the car side and back by the stone hit probability than the front windshield, therefore, toughened glass is widely used in addition to other parts of the front windshield.
At present, in the use of the car front are laminated glass, cracks can be repaired. In addition to the front, around the window glass is damaged because they would spread quickly and fell off, and therefore can not be repaired. In addition, there are some high-end models used in the side windows of the double-layer tempered glass, in ensuring the safety and also to the greatest degree of mute.
Later in the vehicle development process, the inventors and engineers together, through various kinds of high precision technology, endowed with more powerful function for automotive glass. Below we introduce several of them:
1, the HUD display technology, can be in the front vehicle information, vehicle display glass, such as speed, engine speed, oil etc..
2, clean glass, is through the installation of ionization device on the glass, to avoid the dust absorption in the glass;
3, water repellent glass, the glass surface after fluoride treatment in particular, rain on the glass will condense into water droplets fall, no water stains, see clearly, which can help the driver to make correct judgment;
4, plus nitrogen glass, the glass per square millimeter can withstand the pressure of 1200 kg, even when the car is being hit by a piece of metal at 200 kilometers per hour speed, also can not be broken down.
The window broken more common for glass crack caused by stones and other hard object impact front, initially appeared in these crack point, can be repaired in some professional glass beauty shop, but this type of repair technique for crack area requirement is very high, about one or two cm above the broken area can not repair, can only choose the replacement of glass.
Usually, glass breakage, repair personnel will be made as soon as possible repair, many friends will ask, since the wound has emerged, simply do open, have time to repair. Actually this kind of practice is not correct, with the change of temperature in a day, deformation and heat the cold will cause the glass, and continue to run the drag will further erode the breakage, to bring pressure on it continuously damaged, may be enlarged, if missed the best repair area, may repair the effect will be greatly reduced, so that the window is broken, should be the first time to repair.
