Characteristics of AF, Ag and AR coating on the surface of 3D glass cover plate

3D glass cover plate coating is like women's makeup, which can not only make the glass cover plate and back plate more beautiful, but also play the role of oxidation resistance, acid and alkali resistance and UV resistance. Therefore, 3D glass coating is very necessary in today's "face seeing" era! However, glass coating is by no means one kind. Different coatings play different roles. This article focuses on AF, Ag and AR coatings. I'm sure you won't be confused after reading it

I. name explanation and principle

--- anti fingerprint, Chinese is anti fingerprint. Generally, sio2+af materials (don, M4, Dow Corning AF materials) generally adopt vacuum evaporation coating method

principle: AF antifouling and fingerprint proof glass is based on the lotus leaf principle. A layer of nano chemical materials is coated on the outer surface of the glass to minimize the surface tension of the glass, and the contact area between dust and the glass surface is reduced by 90%, so that it has strong hydrophobic, oil resistant and fingerprint resistant capabilities; The glass panel of the video screen keeps a bright and clean effect for a long time

applicable materials: all kinds of glass or plexiglass PC, PMMA, pet

2. Ar - anti reflection, Chinese for anti reflection and antireflection, by improving the transmittance of glass (screen), reduce the reflectivity of glass (screen) to achieve the purpose of antireflection. There are many materials to choose from. Generally, high and low refractive index materials are used for cross stacking plating. Vacuum evaporation plating or magnetron sputtering plating can be used

principle: when light is emitted from light sparse material to light dense material, the reflected light will have half wave loss. After AR film is plated on the glass, the optical path difference of the reflected light on the surface is exactly half a wavelength different from that on the front surface of the film. The reflected light on the front and rear surfaces of the film cancels, which is equivalent to increasing the energy of the transmitted light. And by coating both sides of the glass at the same time, the reflection effect on both sides of the glass can be reduced at the same time

applicable base materials: glass, acrylic (PMMA), PC, CR39 and other plexiglass

3. AG anti glare, Chinese for anti glare, is to achieve the effect of multi angle diffuse reflection after the glass surface is specially treated on one or both sides, so as to improve the visual angle of the picture, reduce the interference of ambient light, and reduce the reflection of the screen. The film can be formed by spraying + baking, using colloidal solutions such as SiO2

principle: through light scattering and diffuse reflection, reduce reflection to achieve the purpose of anti dizziness and anti dazzling, so as to create a clear and transparent visual space, so as to have better visual enjoyment

next, let's talk about the process flow of anti fingerprint treatment

① pretreatment: use weak alkaline detergent or solvent to remove oil, water and other stains on the surface of the substrate, and the effect of ultrasonic cleaning is better

② plating AF solution on the product surface to form a film

③ baking: take out the glass after spraying, put it into the oven (120 degrees, 30 minutes), and adjust it to the best according to the specific requirements and product conditions

④ cleaning: after the product is cleaned, the loading handle should be placed at the unloading position after loading

the three coating processes are similar, but there are changes in the coating method and potion. For example, the AR process flow is as follows:

cleaning → drying → coating → curing → high temperature tempering

III. characteristics and application fields

1 Characteristics of AF coating product:

1) antifouling: it prevents fingerprints and oil stains from adhering and erasing easily

2) scratch prevention: the surface is smooth, comfortable and not easy to scratch

3) thin film: excellent optical performance, without changing the original texture

4) wear resistance: with true wear resistance

af coating product application field:, flat panel, TV, led and other glass display screens

2 A the price of each bag should also be increased by at least 0.5 yuan r coating product characteristics:

1) high penetration: nano optical coating technology can increase the light transmittance of ultra white glass by%

2) durability: it can be maintained in a harsh environment for 25 years

3) prevent condensation: greatly inhibit the condensation of photovoltaic glass

4) scratch resistance hardness: after coating, it can increase 1H hardness scratch resistance effect

5) water resistance: the angle of water droplets falling on it is up to To 110 °, the panel will automatically slide down in the inclined state without affecting the vision

6) easy to clean: and the amount can be reduced by 80%, very easy to clean

ar coating product application fields: front and rear windscreens of automobiles, solar photovoltaic industry (solar panels), range hoods Large outdoor advertising screens, etc.

1) reflect infrared ray: reduce the transmittance of infrared ray on the glass surface to reduce the infrared light entering the room

2) enhance the transmittance: enhance the transmission of other light sources while reflecting infrared ray, Do not affect the indoor lighting effect

3) anti glare: change the light emitted by the light source with diffuse reflection (Ag coating essence) to change the visual stimulation of the reflected strong light to the observer

ag coating product application field:

1) the precious calligraphy and painting frames of advanced galleries and art galleries, so that the calligraphy and paintings and pictures can be preserved for a long time and never fade

2) protection of valuable cultural relics such as museums and archives

3) electronic whiteboard, dlp/lc proposed BPA for fetal D touch screen, dlp/lcd TV wall It has high light transmittance and anti glare

4) precision instrument screen, medical equipment window, LCD window, electronic product window, etc

5) KFC, McDonald's and other restaurants' order cards, the commodity names are clearly visible, and the light reflection phenomenon will not be seen

6) Airport, hotel signs, instruction screens, etc
