A.glass bead for road marking
1) Product Function
Improve the road marking line contrary reflection function. When driving at night, the lamp
shines on the marking line with glass bead in it, the ray of lamp is reflected back parallely. So
the driver can look at the road clearly and drive safely at night.
2) Product Specification:
The main products:
1.No.1-3 beads size distribution according to JT/T 446-2001 Chinese Standard .

B.Coated Glass Bead.
a). Product Introduction
The coated glass bead have been treated with high quality organic materials on their surface,
thus bearing better features in quality. We have developed this unique product with our
advanced technology and it has the following advantages
Features:
A The contrary reflexible of the micro glass beads maintains since we select the materials
which are similar to the nature of micro glass beads.
B In rainy and wet weather, ordinary glass beads would be surrounded by water and result in
the low reflection rate. However, the micro beads with coated can maintain the reflection
effect to a great extent.
C Ordinary glass beads would pile up in the sprayer after absorbing water. However, micro
beads with coated would not so, thus increasing the working efficiency.
D since micro beads with coated contain special adhesives, thus improving the integrity
between the micro beads and the paints.
E Can prevent sinking of micro beads to the bottom of paints.
F after the treatment of coated thus absorbing less dust from air.
b).Product specification
Coated can be done from 50μm-1180μm, based on clients requirements.
c).Technical references
Appearance: beads with round ball shape and no visible impurity.
Refractive index:＞1.5
Density:2.4-2.6g/cm3
SiO2 content:≥68%
size distribution and spherical beads.
Water resistance: when the wastage of 0.1N hydrochloric acid is 10ml, the surface of glass
bead does not fade.
Coated feature: After soaking in water for 30 seconds and dry for 2 hours under in-door t
temperature, they can easily pass through filler while shaking slightly.
C.Glass Bead for Jetting
1) Product function
Glass bead for jetting has the features of chemical stability, high mechanical intensity and
hardness. They can be jetted onto the object surface with compressed air and can be used on
compress glass, rubber, plastic, moulds with metal casting or compressing. The jetting balls
would help reduce elasticity of the surface materials and increase wearing capacity.
2) Product Specification:
Main products specification for jetting according to following table:
No. Diameter(μm) Corresponding sieve size
1 710-425 25-40
2 425-250 40-60
3 250-150 60-100
4 150-100 100-150
5 100-75 150-180
6 75-50 <180
You can choose different size glass bead between 50μm-850μm according to different function.
3) Technical references
Appearance: Clean and transparent, no visible bubbles and impurity.
Density:2.4-2.6g/cm3
Hardness:6-7
Spherical beads:≥75%
SiO2 content:＞70%
4) Package:
1.Using double-deck package, the inner is polythene film and its thickness is not less than
0.5mm; the outer is plastic woven bag to prevent leak or damp. The net weight of each bag is
25±0.2kg.
2.Using double-deck package, the inner is polythene film and its thickness is not less than
0.5mm, the outer is plastic woven bag to prevent leak or damp. The net weight of each is
1000±8kg.
3.According to clients' requirement.
D.Glass Bead for grinding
1) Product Function
With the advantages of smooth surface, even size, high hardness, wearable and stable, widely
used as disperser, grinding media and filler materials in day, paint, ink and chemical industry.
2)Product Specification:
Main products specification for grinding according to following table:
No. diameter(mm) corresponding sieve size
1 1-2 18-10
2 2-3 10-8
3 3-4 8-6
4 4-5 6-4
You can choose different size glass bead between 1mm-5mm according to different function.
