As a material, acrylic sheet can be said to be powerful and can be used to make a variety of craft products. Then many people will ask whether acrylic can be used as a windshield of a car. Let's answer this question. .
Early cars did not have this kind of glass because of their slow speed. With the development of automobile technology, the speed is gradually increasing. Wind and small debris hitting the driver's face have become an increasingly serious problem. In order to reduce this trouble, the manufacturer added a piece of glass to the car, which is called windshield in text. The new windshield makes the driver more comfortable, but they are not enough to withstand small flying debris. These windshields are hand-cut from flat glass. However, unfortunately when the glass is broken, the flat glass will shatter into large pieces of dangerous sharp fragments, which do not seem to have satisfactory windshield characteristics. The real modern windshield was a sudden idea by Ford in the 1920s. Henry Ford was slightly injured due to a piece of windshield shard. Suddenly, he had an idea to sandwich two pieces of glass together and use it in the middle. A layer of PVC plastic divides into something like a sandwich. This technique is still in use. This idea is very suitable for windshield requirements, because the plastic interlayer can prevent the broken glass from falling on the person in the car like a shower. Another advantage is that this layer of plastic makes the windshield have energy absorption and shock absorption performance, which helps protect passengers in the event of an accident. At present, windshield glass is a very important safety component in China. It belongs to the national 3c compulsory certification part and requires national certification (3c certification is only a basic safety certification). Automotive glass mainly plays a protective role, with laminated tempered glass and The sandwich area is mainly tempered glass, which can withstand strong impact. When shattered by impact, the glass will split into small pieces with blunt edges, which is not easy to cause damage to the occupants.
The cracks of the new type of regional toughened glass can still maintain a certain degree of clarity, ensuring that the driver's field of vision is not affected. The acrylic sheet is a colorless transparent plexiglass sheet with a light transmittance of more than 92%. If it is applied to car glass, it needs to be made through a special process to ensure that it can pass the national 3 c mandatory certification. Therefore, ordinary acrylic sheets cannot be directly taken into a car to make a windshield.
