Automobile windshield: the difference between plane type and curved surface type

the development of modern car appearance is closely related to the development of glass technology. As early as more than 40 years ago, the single piece bending windshield was adopted for the front windshield of cars, and the flat windshield was gradually abandoned

nowadays, car windscreens are generally made into a whole large curved surface, with a certain radian up, down, left and right. This kind of curved glass is a product with very high technical requirements no matter from the processing process or the fitting, because it involves many problems such as vehicle type, strength, heat insulation, assembly and so on. The car windshield adopts curved glass. Firstly, from the perspective of aerodynamics

because the normal speed of most modern cars exceeds 100 kilometers per hour, the frontal airflow flowing through the curved glass can reduce eddy current and turbulence, thus reducing air resistance. In addition, the window has developed into an important window in China's industrial field facing the world and a platform for economic and trade exchange and cooperation, which has passed the certification of the international exhibition Alliance (UFI). The edge of the frame has a smooth transition with the body surface, and the glass is integrated with the body. Visually, it can not only feel the overall coordination and beauty, but also reduce the concession of the whole vehicle, that is, adjust the high and low wind resistance coefficient of the condenser. In addition, curved glass has high strength, and thinner glass can be used, which is of certain significance to the lightweight of cars

at present, the curved windshield of cars should have a high flatness at the bending corner, without optical distortion, and the objects outside should not be deformed or dazzled when viewed from any angle on the driver's seat. In the past, the car glass was usually decorated or protected along the glass edge with neat strips. Now the car glass adopts ceramic glaze, that is, the so-called "black frame". Many car windscreens are also coated. The reflective coating process is adopted or the composition of the glass is improved. Only the visible light of the sun enters the compartment to block the ultraviolet and infrared rays, which greatly reduces the suffering of the passengers from the heat. This kind of modern car glass, called "green glass", has been widely used. Fuyao Glass and Zhuhai Huashang energy-saving automotive glass, which are well-known in China, are used for static stiffness measurement, which has become the benchmark of behavior
