Automotive knowledge - Hyundai windshield overview

Although the automotive industry and the glass industry are two different fields of industry, the former is a mechanical manufacturing industry, which is light, but the car's development process, relationship between the two grow closer. Glass technology has completely infiltrated the automotive industry to become part of automotive technology, an indispensable one. Now, people are always from the perspective of vehicle safety and appearance to the research and development of automotive glass, has introduced new varieties. Auto glass windshield before the main. As early as 80 years ago, glass has been installed in the Ford plant produced T-car, was installed in the car with the plate glass front, so that drivers remove the bitter wind and rain. From the next few decades, gradually involved in the automotive glass industry, creating a variety of safety glass - laminated glass, toughened glass and other varieties and regions, which greatly improved the performance of automotive glass.
Laminated glass is used in which a transparent adhesive plastic film can be attached to the story or three glass between the plastic strength and toughness and rigidity of glass together, increasing the ability to crush glass. Tempered glass is ordinary glass quenching the internal organization of a certain stress, so that the strength of the glass be strengthened, broken by the impact, the glass will be split into small pieces with a blunt edge, the crew is not easy to damage.
The glass is tempered glass area, a new species, it is specially treated, can break when under attack, the glass cracks can still maintain a certain clarity to ensure that the driver's field of view is not affected. Currently car windscreen area with laminated glass and laminated glass-based, can withstand strong impact.
Appearance of modern car development and is closely related to the development of glass technology. As early as 40 years ago, car windscreen has adopted a one-piece curved windshield, and gradually abandoned the planar windshield. Today's car windshield is generally made of a type of large overall surface type, up and down have some curvature. This curved glass processing, whether from the cooperation point of view or from the assembly, is a very high technical requirements for products, as it relates to models, strength, heat insulation, assembly and many other issues.
The use of curved glass car windshield, the first from the aerodynamic point of view. Because the normal speed of most modern cars more than 100 km, air flow through the curved glass face can reduce the eddy and turbulence, thus reducing air resistance.
With the edge of the window frame and the body surface smooth transition, glass and body totally into one, both visually and overall coordination was beautiful, but also can reduce the vehicle's drag coefficient. In addition, the curved glass with high strength, thin glass can be used for lightweight cars have a certain significance.
Modern cars have to be curved windshield surface flatness of the corner is higher, can not appear on the optical distortion from the driver's seat of any point of view objects are not outside the deformation is not dazzling. Usually before the car neat glass strip along the edge of the glass modification or protection, and now cars are used on the glass ceramic glaze, the so-called "black border."
There are also many car windshield coating, a reflective coating process or to improve the composition of the glass, only to visible light to enter inside the sun, blocking the ultraviolet and infrared, to a large extent by reducing the crew of hot pain. This is called "green glass" of the modern car glass, has been widely used.
