How to detect the impact resistance of automobile windshield glass?
Depending on the vehicle, the windshield of the vehicle is also different. At present, the windshield of most vehicles is laminated glass, which is easy to break but cannot break holes. Daqing automobile windshield laminated glass has high safety. Because the adhesive film of the middle layer is tough and has strong adhesion, it is difficult to penetrate after impact damage, the fragments will not fall off, and the cornea is closely bonded. Compared with other glass, it has the performance of shockproof, anti-theft, bulletproof and explosion-proof. But with a sharp object, it will crack with a touch.
The front glass is laminated, which is made of two pieces of ordinary glass laminated with glue, so it is fragile and it is difficult to say how much force it can withstand. The wind pressure resistance is usually considered, rather than the external force, and the applied force is basically based on the pressure per unit area. Daqing automobile windshield glass qualified products need to be broken, because in case of an accident, protect the head of the person. Internal and external impact tests were carried out with 227g steel balls and 2260g steel balls.
The glass shield consists of a scratch-resistant layer, a highly transparent PET film, a PSA layer and a PET base film. Compared with the ordinary explosion-proof film, the glass protective screen is installed on the surface of the windshield and has a certain impact resistance, which is equivalent to adding a layer of protective screen on the glass surface. It can not only protect the glass well, but also effectively reduce the risk of glass breaking and injury to the occupants in the car, making driving safer.
But there are many products on the market, so choosing a glass product is not just a matter of choosing one, what should consumers look at when choosing. For automotive glass products, we must first ensure that the vision is transparent and clear.
In addition to light transmittance, the key point we need to pay attention to is hydrophobicity. Take the Japanese Labo-Shield glass shielding as an example, its light transmittance reaches ≥ 91.2%, which is much higher than other glass shielding products. The field of vision will not be affected, and driving at night can ensure excellent clarity.
