How to keep the mirror surface from fogging

In winter, taking a shower is a great treat. But after the beautiful shower, I found that the mirror in the shower room was so white that I couldn't see it. How to keep the mirror surface from fogging?
method one:
Wipe soap or detergent on the surface of the mirror: Apply soap or detergent, wipe evenly on the surface of the mirror, and then wipe it clean, because soap or detergent contains surfactants, which can be reasonably avoided The water vapor condenses into water droplets on the surface of the mirror, which has the purpose of preventing fog.
Advantages: 1. Actual effect;
2. The actual operation is simple.
Defects: 1. Work hard, make sure that the mirror glass is wiped evenly, and wipe the mirror glass;
2. Soap or detergent surfactants are very easy to absorb dust, making mirror glass more easily dirty;
3. The application cycle is short, and it needs to be operated again after many months.

Method 2: Remove and replace the mirror with the actual effect of anti-fog
On some platforms, mirrors with anti-fog effects can be purchased. The basic principle of such anti-fog mirrors is: paste a layer of heatable plastic film with a composite heating wire behind the mirror, and when it must be heated, turn on the heating When the power switch is turned on, the electric heating tube attached to the back of the mirror starts to work, the temperature of the laminated glass rises, the water vapor condensed on the surface of the mirror evaporates, and the mirror becomes brighter and brighter!
Advantages: 1. The actual effect of electric heater defogging is good;
2. Long service life, can reach 5-8 years.
Defects: 1. The power plug must be laid out in advance or the power plug must be laid out again;
2. Safe use of electricity in the wet and cold natural environment of the shower room.
Method 3: Stick anti-fog film on the mirror surface
Another way to change the performance of the mirror surface is to stick an anti-fog film. This type of film is essentially an explosion-proof film, which is essentially the same as the film that you put on the windshield of your car when you buy a car. However, the anti-fog film is made of fully transparent PET to ensure the permeability of the film layer. The surface of the film was then treated with a scratch-resistant and anti-fog layer applied. Generally, there are two ways to achieve the actual effect of moisture-proof and anti-fog: one is hydrophobic, the surface is coated with a hydrophobic layer when the water drops on the surface, it is not easy to adhere to the laminated glass, but it will Sliding down quickly, the actual effect is the same as that of a rose. In addition, one is to apply a hydrophilic barrier layer. When the water vapor condenses on the surface, it does not produce small water droplets one by one, but just spreads on the surface to produce a layer of symmetrical shrinking water, which is not easy to damage the vision of the mirror. Because the particles condensed by the fog water are not large, the anti-fog film for mirrors has a very good effect of water absorption than water repellency.
In addition, in order to better ensure the flatness of the laminated glass of the mirror, all ordinary flat glass is used instead of tempered laminated glass. The PET sheet of the anti-fog film has a certain compressive strength, which can prevent the protrusion of the beveled laminated glass and the scattering of broken glass when the mirror is accidentally broken, ensuring the safety of your application.
Advantages: 1. The actual effect of glass film defogging is very good;
2. Easy to install without wiring;
3. Do not use a switching power supply, can be trusted.
4. Excellent stain resistance, the water absorption of the anti-fog film can automatically clean the stains of the mirror.
5. Explosion-proof performance to prevent accidental rupture and splashing of laminated glass.
