DH Road Marking Reflective Glass Beads道弘牌道路反光玻璃微珠 —— 产品介绍 / Product Introduction
产品概述 Product OverviewDH牌道路反光玻璃微珠采用优质钠钙硅玻璃经高温熔融球化制成，无色透明、高圆度、低气泡。
DH Reflective Glass Beads are manufactured from high-quality soda-lime glass through high-temperature melting and spheroidization. They are colorless, transparent, highly spherical, and contain minimal air bubbles.
嵌入热融标线涂料（Thermoplastic Road Marking）中或面撒（Drop-on），利用逆反射（Retro-reflection）原理将车灯光线反射回驾驶员眼中，确保夜间、雨雾天车道线清晰可见，提升行车安全。
Embedded in thermoplastic road marking paint (Drop-on & Intermix), they use the retro-reflection principle to reflect vehicle headlight beams back to the driver, ensuring lane markings remain clearly visible at night and in foggy/rainy conditions, significantly improving road safety.
