How does low-reflective laminated glass effectively isolate UV rays?What are its heritage protection features?

Low-reflective laminated glass is a specially designed glazing material, which achieves effective isolation of UV rays and protection of cultural relics through several layers of films of different materials and optical technology. The working principle of low-reflective laminated glass and its characteristics in the protection of cultural relics are described in detail below.

The working principle of low-reflection laminated glass:

1. Film selection and structural design: Low-reflective laminated glass consists of multiple layers of specially designed films, usually containing absorbing, anti-reflective, and interlayer layers. These film materials have special optical properties that enable selective absorption and reflection of UV rays. 2.

2. UV Absorption: The absorber film in low reflective laminated glass selectively absorbs UV energy and converts it to other forms of energy, thus preventing UV radiation from entering the glass.

3. Reflection: Low-reflection laminated glass adopts an anti-reflective layer film, through the refractive index matching of materials and the interference effect of multi-layer film, part of the ultraviolet radiation can be reflected so that it can not penetrate the glass.

The characteristics of low-reflection laminated glass in the protection of cultural relics:

1. Ultraviolet filtering effect: reflection laminated glass can effectively isolate ultraviolet rays, with a reflectivity is only 0.8%, to prevent harmful light erosion of cultural relics. This is very important to avoid the photo-oxidation reaction of cultural relics due to prolonged UV irradiation.

2. High transmittance: Low-reflective laminated glass has a high transmittance rate, and usually reaches more than 98%. This means that the audience can see the artifacts clearly through the glass, providing a better viewing experience, and there will be no reflection phenomenon, which is convenient for tourists to take photos.

3. explosion-proof and smash-proof: even if the low-reflective laminated glass is broken, the fragments will be adhered to the laminated layer and will not splash, which effectively protects the audience and cultural relics.

4. Durability and safety: Low-reflective laminated glass has good durability and safety, and the laminated film can effectively absorb the impact, preventing fragments from splashing, to ensure the safety of the audience and cultural relics.

5. Optical Transparency: Low-reflective laminated glass has desirable optical transparency, and does not produce obvious reflection or refraction phenomenon, to provide the audience with a clearer, more realistic observation experience.

In summary, low-reflection laminated glass through special film selection, structural design, and optical technology, achieves effective isolation of ultraviolet rays and has high transmittance, explosion-proof, and anti-smash characteristics. In the protection of cultural relics, low-reflective laminated glass can inhibit photo-oxidation reactions, protect cultural relics from ultraviolet rays, and at the same time provide a good display effect and viewing experience. This enables the cultural relics to be better displayed to the audience, and the audience can also clearly observe the cultural relics, which improves the quality and effect of cultural relics' protection and inheritance.
