Method 1: Heating the mirror to reduce the temperature difference between the water vapor and the surface of the mirror;
Method 2: Use chemical coating to apply a layer of substance on the mirror to prevent fog from forming on the surface of the mirror;
Method 3: Use the principle of hydrothermal anti-fog, heat the mirror with hot water, and use a natural method to reduce the temperature difference between the water vapor and the surface of the mirror.
Almost all products on the market are derived from the above three principles.
The mirrors used in high-end hotels do not fog, which belongs to the first method. The electric heating anti-fog mirror is used, and a layer of electric heating anti-fogging film is pasted on the back of the mirror. The electric heating wire is used to efficiently convert the electric energy into heat energy, so that the mirror surface heats up and prevents water vapor from condensing. Anti-fog on the mirror surface. The material of the heating wire is mainly carbon fiber, and there are two types of connection methods: series or parallel, among which the reliability of the parallel type is higher. Heated anti-fog is a thorough and long-lasting anti-fog method, but electric-heated anti-fog mirrors need to be connected to electricity, which brings concerns and inconvenience to people—bathrooms or toilets are very humid spaces, and supplies that need to be connected to electricity will definitely bring It is a safety hazard; in addition, it is necessary to not reserve a power interface behind or near the mirror, otherwise it will be very troublesome to connect the wiring. The anti-fog mirrors used in hotel clubs are all electric anti-fog mirrors.
