[China Glass Network] Although the automobile industry and the glass industry belong to two different fields of industry, the former belongs to the machinery manufacturing industry and the latter belongs to the light industry. However, from the perspective of the development history of the automobile, the relationship between the two is getting closer and closer. Glass technology has completely penetrated into the automotive industry and has become an indispensable member of the automotive technology field. Nowadays, people always research and develop automotive glass from the perspective of car safety and appearance, and constantly introduce new varieties. The automobile glass is mainly composed of windshield. As early as 80 years ago, the glass was installed on the T-type car produced by the Ford plant in the United States. At that time, it was installed on the front end of the carriage with flat glass, which made the driver avoid the wind and rain. From the following decades, the glass industry has gradually entered the automotive industry, creating a variety of safety glass - laminated glass, tempered glass and regional tempered glass, which greatly improved the performance of automotive glass.
Laminated glass
The laminated glass refers to a transparent adhesive plastic film attached between two or three layers of glass, which combines 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.
Regional tempered glass
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. At present, the front windshield of the automobile is mainly composed of laminated tempered glass and tempered glass in the interlayer region, and can withstand strong impact force.
The curved windshield of the generation car should have a high degree of flatness at the corner of the bend, and no optical distortion can occur. The object outside is not deformed or dazzled from any angle on the driver's seat. In the past, car glass was usually decorated or protected along the edge of the glass with neat strips. Now the glass on the car is made of ceramic glaze, the so-called "black border".
