1. Scattering effect of oil sand particles
The anti-peeping effect of oil sand craft glass first benefits from the scattering effect of oil sand particles. In the oil sand process, many tiny oil sand particles are attached to the surface of the glass. The presence of these particles changes the propagation path of light on the glass surface. When light shines on the surface of oil sand glass, due to the different refractive indices of oil sand particles and surrounding media (such as air and glass itself), the light will scatter on the surface of the particles. From the perspective of the peeper, the light no longer propagates directly through the glass in a straight line, but scatters in all directions, making it impossible for the peeper to clearly see the objects on the other side of the glass. This scattering effect is similar to frosted glass, but the oil sand process can more accurately control factors such as the size and distribution of particles, thereby achieving an ideal anti-peeping effect.
2. Diffuse reflection characteristics of oil sand layer
The oil sand layer also has diffuse reflection characteristics, which plays an important role in the anti-peeping effect. The surface of the oil sand layer is not smooth and flat, but is composed of many tiny irregular structures, which are determined by the oil sand particles and their distribution state. When light shines on the oil sand layer, diffuse reflection occurs on these irregular surfaces. Unlike the mirror reflection of ordinary glass, diffuse reflection reflects light in all directions instead of concentrating on a specific reflection direction. This means that the reflected light received by the peeper standing on one side of the glass is messy and cannot form a clear image, thus achieving the anti-peeping function.
3. Opacity and light blocking of oil sand layer
The oil sand layer of oil sand craft glass itself has a certain degree of opacity, which is also a factor in achieving the anti-peeping effect. The oil sand particles and related substances in the oil sand layer block the penetration of light to a certain extent. Although the oil sand craft glass can still transmit light, it effectively blocks the light. From the perspective of the peeper, when the object on the other side of the glass passes through the oil sand layer, its light intensity is greatly weakened, and due to the scattering and diffuse reflection of the oil sand layer on the light, it is difficult for the peeper to distinguish the details of the object, thereby achieving the purpose of preventing peeping.
4. Changes in multi-angle light propagation
When observing the oil sand craft glass from different angles, its anti-peeping effect still exists, because the oil sand particles can change the propagation of light at all angles. Whether the light hits the oil sand glass from the front, side or oblique angle, the oil sand particles will scatter, diffusely reflect and block the light. This all-round change in light propagation ensures that under various possible peeping angles, it is difficult for the peeper to see the objects on the other side through the glass, thus effectively ensuring the reliability of the anti-peeping effect in practical applications.
