What is the car lampshade made of? How to deal with water mist inside the car lampshade?
Car lampshades are usually made of high grade polycarbonate (PC resin).
Polycarbonate has become the preferred material for automobile lampshades because of its high hardness, high toughness, high strength and good light transmission and UV resistance. In addition, the lamp shade of the headlamp may also use transparent PC material, because it can withstand high temperatures, while the taillight is commonly used PMMA (acrylic or plexiglass) material, because it has high light transmittance and certain high temperature resistance.
These materials were chosen not only on the basis of their physical and optical properties, but also on the basis of their buffering properties against violent impacts, as well as their ability to resist acid and alkali corrosion to the environment.
The methods to deal with the water mist in the car lampshade mainly include:
Turn on the headlights: The heat generated by the headlights gradually dissipates the water mist.
Sun drying: Park the vehicle in the sun and use the heat of the sun to evaporate the water mist.
Use a hair dryer: Use a hair dryer to dry the car lampshade, you can open the hot air of the hair dryer for operation.
Remove the headlight treatment: If the above method is not effective, you can consider removing the headlight assembly for drying or blow drying treatment.
Use a desiccant: Place a desiccant inside the lampshade to help absorb moisture inside.
Please note that when dealing with the problem of water fog in car headlights, it should be ensured that the operation is safe to avoid unnecessary damage to the vehicle. If there are already large water droplets forming inside the headlight, or even serious water accumulation at the bottom of the headlight, it may indicate that the headlight assembly is damaged or sealed, then the various components of the headlight should be checked whether they are intact, and the headlight assembly should be replaced if necessary.
