Microbilles de verre : specifications techniques et normes

Linghang produces solid glass beads and glass microspheres from 20 to 500 mesh at our factory in Yongqing County, Hebei. Every grade is characterised by refractive index (R.I.), retroreflectivity (RL), particle size distribution and roundness — the four parameters that determine how a bead performs in road marking, grinding, blasting and composites.

1. Granulometries standard et specifications

Valeurs typiques. Granulometries sur mesure de 20 a 500 mesh sur demande.

Mesh Particle Size R.I. Retroreflectivity RL (mcd/m²/lx) Typical Application
20/30 0.85 - 0.60 mm 1.50 150 - 250 Road marking drop-on, blasting
30/40 0.60 - 0.425 mm 1.50 200 - 300 Road marking drop-on & premix
40/60 0.425 - 0.25 mm 1.50 250 - 400 Premix markings, composites
60/80 0.25 - 0.18 mm 1.50 300 - 450 Fine premix, reflective sheeting
80/100 0.18 - 0.15 mm 1.50 350 - 500 High-grade premix, coatings
100/200 0.15 - 0.075 mm 1.50 300 - 450 Industrial coatings, fillers
16/30 1.18 - 0.60 mm 1.50 - Grinding / milling media
20/40 0.85 - 0.425 mm 1.50 - Grinding media, shot blasting
Note on RL values: retroreflectivity measured on a finished marking depends on bead embedment depth, drop-on rate (typically 0.3–0.45 kg/m²) and the paint system used — not on the bead alone. We quote bead R.I. and grading data; final RL is verified on your own test marking.

2. Normes internationales auxquelles nous fournissons

Standard Region What It Covers
AASHTO M247 USA Drop-on & premix beads for pavement markings: gradation, R.I., roundness, moisture resistance.
EN 1423 / EN 1424 EU Type 1 / Type 2 drop-on materials and premix glass beads; R.I. and grading requirements.
BS 6088 UK Glass beads for road marking: particle size distribution, refractive index, chemical resistance.
GB/T 24722-2020 China Pavement marking glass beads: No.1-4 bead uses, R.I. classes, roundness, magnetic particles, heavy metals.
GB/T 16311-2024 China Road marking quality & test methods: 4 retroreflectivity classes (I-IV), 48h-30d initial reading window, skid resistance BPN.
ASTM D4280 / D1107 USA Premix and drop-on beads: sieve analysis, R.I. determination methods.
ISO 9001 International Quality management system covering raw glass selection, melting, grading and batch QC.

Beads for road marking are graded by refractive index: R.I. 1.50 for standard drop-on and premix applications, 1.70–1.90 for high-brightness markings, and above 1.90 for premium wet-night-visibility systems. Roundness matters as much as clarity: under GB/T 24722-2020, No.1 and No.2 beads require at least 80% roundness, and defect beads at medium/high refractive index are capped at 20%.

  • Raw material control: recycled and virgin glass cullet is inspected for colour, iron content and contamination before melting — iron and opaque particles are the main cause of low retroreflectivity.
  • Batch-testable: R.I., RL and particle size distribution are checked per batch, and a test report can accompany each shipment on request.
  • Custom grading: non-standard mesh windows and blended gradations can be produced to your coating or blasting specification.
  • Export packing: 25 kg bags, 500 kg / 1000 kg jumbo bags, or 25 kg cartons on pallets; container loading plans provided before shipment.

If you are evaluating a supplier, the fastest test is a sample marking: we ship samples so you can check roundness under a microscope, run a sieve analysis, and measure RL on a trial stripe with your own paint. Tell us your mesh window, application and target market, and we will confirm the grade, MOQ and FOB price.
