[China Glass Net] Automotive glass is mainly composed of laminated tempered glass and laminated tempered glass, which can withstand strong impact. Laminated glass means that a transparent adhesive plastic film is applied between two or three layers of glass to combine the toughness of the plastic with the rigidity of the glass, thereby increasing the crush resistance of the glass. Tempered glass refers to the quenching of ordinary glass to form a certain internal stress in the internal structure, so that the strength of the glass is strengthened. When the impact is broken, the glass will split into small pieces with blunt edges, which is not easy to cause damage to the occupants. The regional tempered glass is a new type of tempered glass. It has been specially treated to maintain a certain degree of sharpness in the crack of the glass when the impact is broken, so as to ensure that the driver's field of view is not affected.
1. The glass on the car, especially the windshield, has a curved deformation at the edge where they contact the car body. It is precisely because this curvature can cause the car exterior to deform when passing through the arc, thus affecting the passengers inside the car. Vision. The middle scene moves at a normal speed, and the edge of the scene moves faster, which has a certain visual slowing effect.
2, the car is driving in rainy days, the glass is often affected by rain, seriously affecting the driver's line of sight and safety. In order to alleviate this situation, more and more models use hydrophobic glass. Water-repellent glass is coated on the outer surface of the front windshield with an organic fluororesin as a water repellent. The thickness of the coating ranges from tens of angstroms to hundreds of angstroms. When the car is moving at a speed of 50-60km/h, the raindrops on the glass surface will splash and maintain good visibility without using a wiper. The hydrophobic agent's organic fluorine cannot be maintained for a long time, and the glass needs to be maintained and coated regularly to maintain good water repellency.
3. The car with automatic wiper is equipped with a rain sensor on the front windshield. The sensors of most models are hidden behind the glass, which is the position of the rearview mirror. It can be based on the amount of rain falling on the glass. Adjusting the action of the wiper greatly reduces the trouble of the driver.
4. During the driving process, passengers will hear noise from many aspects in the car. For example: engine, tire noise, external noise, etc. Ordinary car glass can block some noise, but it can't meet the comfort requirements of high-end car owners, and the sound-proof glass can effectively block more noise.
