1.6 Characteristics of refractive index glass beads

When using 1.6 refractive index glass beads for rainy - day roads and roads with high - reflectivity requirements, the following steps should be taken. First, select the appropriate marking paint, such as hot - melt type or two - component paint, which have excellent night - time and rainy - day reflectivity. Carefully check that the paint is free of lumps and impurities and meets relevant standards for performance indicators like water resistance and alkali resistance. Then, process the glass beads. Use standard sieves to screen them, wash them with clean water or blow them clean with compressed air to remove oversized, undersized particles and impurities. If possible, coat the glass beads to enhance adhesion and endow properties such as self - cleaning, anti - fouling, and moisture resistance, thus preparing well for subsequent marking construction.
