What is the black area on the windshield called?
3 Answers
The black area on the windshield mainly consists of black particles, which help distribute heat more evenly to prevent the windshield from cracking. Here is some information about automotive windshields: 1. Laminated glass refers to a type of glass where a transparent adhesive plastic film is placed between two or three layers of glass, combining the toughness of plastic with the hardness of glass to enhance the glass's resistance to breakage. 2. Tempered glass is made by quenching ordinary glass to create internal stresses, thereby strengthening the glass. When impacted and broken, it shatters into small, blunt-edged fragments, reducing the risk of injury to passengers. 3. Zoned tempered glass is a new type of tempered glass that undergoes special treatment. When impacted and cracked, the glass maintains a certain level of clarity, ensuring the driver's field of vision remains unaffected. Currently, most automotive windshields are made of laminated tempered glass or laminated zoned tempered glass, which can withstand strong impacts.
The black area on the front windshield is commonly referred to as the ceramic dot matrix band or sunshade band. Essentially, it's a black ceramic layer applied to the edges of the windshield, primarily serving to conceal the adhesive used for fixing the glass, preventing unsightly marks post-installation. I often notice how some vehicles cleverly design this area to distribute stress on the glass, reducing the risk of cracks caused by vibrations while driving. Additionally, it minimizes sunlight reflection, reducing glare during driving, thereby enhancing safety and comfort. If you're a long-distance driver, you might appreciate how it reduces UV rays entering the cabin, protecting the dashboard from sun damage. During the installation of a new windshield, workers must handle this ceramic band carefully—damaging it could lead to leaks or poor sealing, compromising the vehicle's structural integrity. For regular cleaning, a gentle wipe is sufficient; avoid strong acidic cleaners as they can wear down or cause the ceramic coating to peel. Though a minor detail in automotive design, its practicality is immense, impacting overall driving experience and durability.
As an average car owner, I think that dark area at the top of the windshield is called the black border or sunshade ceramic strip. When I drove an old car before, I noticed that sunlight caused severe glare on the windshield, making it hard to see the road. It was only later that I realized the black border helps reduce glare. It's not just for aesthetics—it also hides the adhesive used to secure the windshield, as exposed edges would look unsightly. Once, when replacing the glass, a technician told me the dot matrix in this area disperses pressure to prevent the glass from shattering. Nowadays, new cars prioritize this design since it’s tied to safety and comfort. For maintenance, I gently wipe it with a soft cloth to avoid scratching the ceramic coating. Neglecting it could lead to aging from prolonged exposure to wind and sun, causing adhesive exposure or water leaks. In fact, this black border also aids in heat insulation and moisture resistance, helping to keep humidity and high temperatures out of the cabin. It’s both convenient and practical to maintain.
