How does the tempered glass used on the surface of the DY8004B underground lamp effectively resist external scratches and wear through its high hardness, thereby maintaining the lasting beauty of the lamp's appearance?

The tempered glass used on the surface of the DY8004B underground lamp has high hardness characteristics, which effectively resists external scratches and wear, thereby maintaining the lasting beauty of the lamp's appearance. Tempered glass is a specially treated glass. The surface compressive stress generated by rapid cooling after heating treatment makes it have higher hardness and strength than ordinary glass. This high-hardness tempered glass makes the DY8004B underground lamp not easily scratched or worn by external objects during use, thus maintaining its beautiful and neat appearance.

The high hardness characteristics of tempered glass are mainly due to its internal stress distribution. During the manufacturing process of tempered glass, the glass is heated to a softening temperature and then rapidly cooled, so that the surface of the glass cools rapidly while the internal temperature remains high, resulting in the formation of compressive stress inside and tensile stress on the surface. This internal compressive stress makes the tempered glass harder when subjected to external forces and less likely to break or deform.

Since the surface of the DY8004B underground lamp uses tempered glass, its surface has a high hardness and can effectively resist external scratches and wear. In daily use, if there are sharp objects or hard objects scratching the surface of the underground lamp, due to the high hardness of tempered glass, these objects are difficult to scratch or damage the surface of the lamp. At the same time, even if the surface of the underground lamp is exposed to the external environment for a long time, it is not easy to cause surface wear and damage due to the wind and rain outside, maintaining its lasting beauty.

Based on the above, it can be known that the tempered glass used on the surface of the DY8004B underground lamp effectively resists external scratches and wear through its high hardness characteristics, maintaining the lasting beauty of the lamp's appearance. This feature enables the underground lamp to maintain a good appearance for a long time in the outdoor environment, prolonging its service life and improving the product's use value and aesthetics.
