DH Glass Beads | 道弘玻璃珠 | B2B Video Product Description
一、视频内容概述 | Video Content Overview本视频展示了廊坊市道弘玻璃微珠有限公司（ Langfang Daohong Glass Beads Co., Ltd.
）生产的道路反光玻璃微珠（ Road Reflective Glass Beads
）在生产环节的细节把控，以及在道路热熔标线施工现成的实际应用过程。 in production quality control and real-world thermoplastic road marking construction.
视频中特别提及： A key highlight in the video:
• 现行新国标（GB/T 16311、JT/T 280等）明确要求，热熔反光标线涂料中预混（内混）玻璃微珠的质量含量不得少于30%。 The new National Standard (GB/T 16311, JT/T 280) requires that the premixed (intermix) glass beads content in thermoplastic reflective marking paint must be no less than 30% by weight.
• 道弘（DH）玻璃微珠严格满足该标准，确保标线在长期服役中的逆反射性能与夜间行车安全。 DH Glass Beads fully comply with this standard, ensuring long-term retroreflection performance and nighttime driving safety.
二、核心产品与技术参数 | Product Specifications & Technical Parameters道弘（DH）道路反光玻璃微珠严格遵循新国标及国际通用标准（如 EN1423/1424, AASHTO M247, BS6088
），主要技术参数如下： ). Main technical parameters are as follows:
参数项 Parameter | 规格 Specification | 说明 Description |
折射率 Refractive Index (RI) | 普通型 Normal: RI ≥ 1.50
高折射 High: RI ≥ 1.90 | 可根据雨夜反光等特殊需求定制 Customizable for rainy-night reflection |
成圆率 Roundness | 面撒珠 Drop-on: ≥ 90%
内混珠 Intermix: ≥ 80% | 保障光线均匀逆反射 Ensures uniform retroreflection |
粒径分布 Grain Size Distribution | 0.1–0.6mm / 0.7–1.2mm
20 mesh–325 mesh | 对应国标1号、2号、4号珠；支持定制化筛分 Custom sieving available |
密度 Density | 2.4 – 2.6 g/cm³ | 符合国际标准 Within international standards |
磁性颗粒含量 ic Particles | ≤ 0.1% | 减少杂质对标线附着力与反光值的负面影响 Reduces impurities' negative impact |
莫氏硬度 Mohs Hardness | 6 – 7 | 耐磨耐压，适合重载交通 Wear-resistant for heavy traffic |
外观形态 Appearance | 无色透明或乳白色光滑球体 Colorless transparent / opaque white spheres | 表面光洁，耐候性强 Smooth surface, excellent weatherability |
玻璃微珠含量 Glass Bead Content | ≥ 30%（内混 Premix） | 满足新国标要求 Complies with new National Standard |
三、施工现场应用与工艺要点 | Construction & Application3.1 预混（Intermix）• 玻璃微珠在涂料生产阶段按比例（≥30%）混入。 Glass beads are mixed into the paint at production stage (ratio ≥ 30%).
• 随标线磨损持续露出新珠，维持长期反光。 As the marking wears, new beads are continuously exposed, maintaining long-term reflectivity.
3.2 面撒（Drop-on）• 在标线涂布后立即均匀撒布于表面。 Immediately applied to the surface after paint coating.
• 嵌入深度约为珠径的50%–70%。 Embedding depth: approximately 50%–70% of bead diameter.
• 提供初始高亮逆反射值（白线初始逆反射值可达150 mcd·m⁻²·lx⁻¹以上）。 Provides high initial retroreflection (white line initial RL ≥ 150 mcd·m⁻²·lx⁻¹).
3.3 施工提示 | Construction Tips• 面撒量通常控制在0.3–0.4 kg/m²。 Drop-on rate: typically 0.3–0.4 kg/m².
• 撒布时机需在涂料半凝固态进行，避免过深埋没或过浅脱落。 Timing: apply when paint is in semi-solidified state, avoiding over-embedding or shallow detachment.
