After heavy rain or melting snow, you may sometimes find that there is a layer of fog inside the headlights or taillights of your car. Sometimes the situation is very exaggerated and it will be filled with small water droplets. What should I do if I encounter this problem? Car light waterproof and breathable membrane The manufacturer will tell you the answer.
If we want to know the reason why the headlights are flooded, we must first understand the structure of the headlights. Anyone who knows cars knows that The lights and taillights are waterproof, but they are not sealed. Behind the lamp, a vent pipe or vent is specially designed to dissipate heat from the lamp. Because halogen and xenon lamps generate a lot of heat when they light up, if they cannot be ventilated, the air inside the lamp will heat and expand, and may even burst. Since the lamp is ventilated, the water vapor in the air can enter the car lamp together with the air. After encountering cold and condensation, the water mist remains in the car lamp.
You can use waterproof and breathable film for car lights to be used in car lights. The film is made of ptfe polymer. Currently Regardless of domestic and foreign technologies, the small pore size of the waterproof and breathable membrane is 0.1 micron, and the diameter of the water vapor molecule is about 0.0004 microns (μm), so the electronic waterproof and breathable membrane cannot block water vapor. Uelectronic waterproof and breathable membrane has three major functions: Waterproof: 0.1-1.0 micron micropores, the pore diameter is 10,000 times smaller than water beads, preventing moisture from passing through, well protecting sensitive parts, avoiding liquid erosion, and extending the service life of the product.
Car light waterproof and breathable membrane can achieve product ventilation, balance pressure and reduce condensation, while also filtering liquid and other pollutants things. The protection level reaches IP67 or above. Interested parties can enter the store and contact us.
