As an important part of the car, the performance requirements of car windscreen mainly include the following aspects:
Optical properties: Car windscreens need to have good optical properties to ensure that the driver's vision is clear, without chromatic aberration, and without glare. This requires that the light transmittance and reflectivity of the windshield must meet relevant standards to ensure that drivers can clearly see the road and traffic conditions ahead while driving.
Strength and durability: Car windscreens need to have a certain degree of strength and durability and be able to withstand external forces such as impact and friction. This requires that the material and structure of the windshield must be able to meet the requirements of relevant standards and regulations to ensure that the windshield will not be broken or severely deformed in the event of an impact, and that it will not crack or age due to long-term use.
Anti-fog: Car windscreens need to have good anti-fog properties to ensure that drivers can clearly see the road and traffic conditions ahead in rainy days, foggy days, etc. This requires that the windshield must have excellent anti-fog performance, which can be achieved by using anti-fog agents, electric heating wires, etc.
Thermal insulation: Car windscreen needs to have good thermal insulation, which can effectively block ultraviolet and infrared radiation, reduce the temperature inside the car, and improve driving comfort. This requires that the windshield must be made of materials and processes with good thermal insulation properties.
Safety: Car windscreens need to have high safety to ensure the safety of drivers and passengers. This requires that the windshield must have a certain impact resistance and penetration resistance, and be able to withstand a certain degree of impact and collision.
To sum up, the performance requirements of car windscreen mainly include optical performance, strength and durability, anti-fogging, heat insulation and safety. In order to meet these requirements, the production and use of car windscreens must comply with relevant standards and regulations to ensure the driving safety and comfort of drivers.
