What Are the Consequences of a Damaged Car Door Waterproof Membrane?
1 Answers
The consequence of a damaged car door waterproof membrane is that after the car is exposed to rain, water will seep into the interior through various seams on the car body. Without a waterproof strip, water will inevitably leak into the car. Information about the waterproof membrane is as follows: 1. Function of the waterproof membrane: After multiple layers of anti-reflective coating are applied to the lens surface, the lens becomes particularly prone to stains, which can damage the anti-reflective effect of the coating. Under a microscope, the anti-reflective coating appears as a porous structure, making it especially susceptible to oil infiltration. The solution is to apply an additional top coating with oil and water-resistant properties over the anti-reflective layer, known as the waterproof membrane. This layer must be extremely thin to avoid altering the optical performance of the anti-reflective coating. 2. Process of the waterproof membrane: The material for the anti-stain coating is primarily fluorides, and there are two processing methods: immersion and vacuum coating, with the latter being the most commonly used. After the anti-reflective layer is completed, fluorides can be deposited onto the reflective coating using an evaporation process. The anti-stain coating covers the porous anti-reflective layer, reducing the contact area between water, oil, and the lens, making it harder for oil and water droplets to adhere to the lens surface, hence it is also referred to as the waterproof membrane.
