| 什么是消光效果？ What is extinction effect? 比如色彩，不论是消光还是光亮的外表，都是我们的感官所形成的一种主观印象。光线从一个平整的表面反射到我们的眼睛中，我们根据其光泽进行归类。 For example, color, whether extinction or bright appearance, is a subjective impression formed by our senses. Light rays are reflected from a flat surface into our eyes, and we categorize them according to their gloss. 精确地说，只有照射在表面的部分光线被直接反射回来，其余的进入漆膜，在内部散射开来，并被颜料和基材吸收。而反射的强度则取决于表面的平整度。例如镜子，众所周知对光线反射率高，其表面十分光亮。相反，微观粗糙的漆膜表面散射光线，只反射部分光线。 To be precise, only part of the light illuminated on the surface is directly reflected back, and the rest enters the paint film, scatters inside, and is absorbed by pigments and substrates. The intensity of reflection depends on the smoothness of the surface. Mirrors, for example, are known to have a high reflectivity of light and a very bright surface. On the contrary, the surface of the micro-rough paint film scatters light, reflecting only part of the light. |
