Before understanding the principle of anti-fog film, we must first know the reason why the bathroom mirror fogs. Water vapor will condense when it is cold, which is the root cause of fogging in the bathroom mirror. When the water vapor encounters the bathroom mirror with low temperature, it condenses into a layer of water mist on the surface, which makes the surface form diffuse reflection and cannot reflect normally, resulting in the inability to use the bathroom normally. mirror.
The temperature of the shower water is about the same as the body temperature. Between 35°C and 40°C, the surface temperature of the bathroom mirror is slightly lower than the room temperature. The larger temperature difference + the humid air after bathing causes the bathroom smart mirror to fog up. necessary condition.
Especially in winter, the room temperature is lower, and the temperature difference between the bathroom mirror and the air is larger, so the fog formed is also thicker, and the time for the fog to dissipate naturally is longer.
The mirror anti-fogging film can efficiently convert electrical energy into heat energy, and directly conduct the heat energy to the lens, so that the temperature of the mirror surface can prevent water vapor from condensing on the mirror surface, so as to achieve the effect of anti-fog. The approved input power of the anti-fog film will keep the mirror surface temperature balanced and save energy effectively. With a thickness of only 0.4mm, it is fully attached to the back of the mirror, and the temperature is efficiently transmitted to the mirror surface, reducing heat loss, protecting your lenses and achieving the effect of safety mirrors.
