Mobile phone 3D glass coating, such as women make up, not only can make the glass cover plate, back plate is more beautiful, but also play the role of oxidation resistance, acid and alkali resistance, anti ultraviolet. Therefore, the mobile phone 3D glass coating in the now look at the face of the times is very necessary! However, the glass coating is not a kind of different coating plays a different role, this article focuses on AF, AG, AR coating, I believe you will be able to see after reading.
1. Noun explanation and principle
1.1 AF ---- Anti-fingerprint. General SiO2+AF materials (DON, M4, AF, Dow Corning materials) by vacuum evaporation method.
Principle: AF anti fingerprint antifouling glass is according to the principle of lotus leaf, a layer of nano materials in chemical glass is coated on the outer surface of the glass, the surface tension is reduced to the minimum, 90% to reduce dust contact with the glass surface area, which has strong hydrophobic, anti oil, anti fingerprint ability; the screen glass panel has long maintained a smooth effect beautiful.
Applicable materials: all kinds of glass or plexiglass PC, PMMA, PET...
1.2 AR --- anti-reflection, by improving the glass (screen) transmittance, reduce the glass (screen) reflectivity to achieve the purpose of penetration. Optional materials are more commonly used in high and low refractive index materials stacked stacked up, you can use vacuum evaporation plating can also use magnetron sputtering.
Principle: when the light from the material into denser material optically thinner, the reflected light will have half wave loss, deposition of AR film on the glass surface, the reflected light path than before membrane surface reflected light difference is just half a wavelength, two films before and after surface reflection cancellation, which is equivalent to increasing the transmission light the energy. And the two sides of the glass can be simultaneously reduced to reflect the effect by coating both sides of the glass at the same time.
Applicable material: glass, acrylic (PMMA), PC, CR39 and other organic glass.
1.3 AG --- anti-glare, the single or double special processing of the glass surface to multi angle diffuse reflection effect, so as to improve the visual angle of the screen, reduce the interference of ambient light, reduce the reflective screen. Can be used to spray the method of baking into the film, the use of SiO2 and other colloidal solutions.
Principle: through light scattering and diffuse reflection, to reduce the reflection to achieve the purpose of anti vertigo, anti glare, in order to create a clear and transparent visual space, so as to have a better visual enjoyment.
2. Technological process
AF technological process:
Below we talk about specific fingerprint processing process.
The former process: the use of alkaline detergent or solvent to remove surface oil and moisture and other stains, the ultrasonic cleaning effect is better;
1)AF liquid coating on the surface of the product film;
2)Baking: after spraying, remove the glass and put into the oven (120 degrees, 30 minutes), depending on the specific requirements and product conditions to adjust to the best;
3)The cleaning products: after cleaning, packaging.
Three coating processes are almost the same, but the way the coating and liquid changes, such as the AR process is as follows:
Cleaning→drying →coating→ curing→ high temperature tempering
3. Features and Applications
3.1 AF coating product characteristics:
1)Anti-pollution: to prevent fingerprints and oil pollution is not easy to adhesion, easy to erase;
2)Scratch resistant: smooth surface, feel comfortable, not easy to scratch;
3)Thin film: excellent optical properties, does not change the original texture;
4)Wear resistance: with the degree of wear resistance.
AF coating product applications: mobile phones, flat-panel TVs, LED and other glass display
3.2 AR coating product characteristics:
1)High penetration: nano optical coating technology can make the ultra white glass transmittance increased by 2-3%
2)Durable: can be maintained in a harsh environment for 25 years
3）To prevent condensation: restrains the generation of condensation photovoltaic glass
4)Scratch hardness: after coating can increase the hardness of 1H scratch scratch effect
5)Resistance to water: water droplets fall on the water above the angle of >110 degrees, the panel in the tilt of the automatic slide, and does not affect the visual
6)Easy to clean: and the amount can be reduced by 80%, easy to clean up
AR coating products: automotive front and rear windshield, solar photovoltaic industry (solar panel), range hood, outdoor large advertising screen, etc.
3.3 AG coating product characteristics:
Figure: anti-glare Samsung mobile phone
1)Reflection infrared: reduce the infrared ray on the surface of the glass to reduce the incidence of infrared light.
2)To enhance the transmittance: in the reflection of infrared light while enhancing the penetration of other light sources, does not affect the indoor lighting effect.
3)Anti-glare: the light emitted by the light source with the diffuse reflection (AG coating essence) to change the reflection of strong light on the visual stimulation of the observer.
Application of AG coating products:
1) Senior gallery and Museum of precious paintings of the frame, and the calligraphy and paintings and pictures stored for a long time, never fade.
2) Museums, archives and other precious cultural relics protection.
3) Electronic whiteboard, DLP/LCD touch screen, DLP/LCD TV wall with high light transmittance and glare.
4) Precision instrument screen, medical device window, LCD display window, electronic product window, etc..
5) KFC, McDonald's and other restaurants point meal card, the name clearly visible, will not see the phenomenon of light reflection.
6) Airport, hotel signs, instructions screen, etc..
