A.lass 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 parallel. 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 Standard of Chinese Tariff
 Ministry.

Table 1 Glass bead Size Distribution (JT/T446-2001 International Standard)

 

2.Products according to international standard include: English BS6088Korean KS and American AASHTO etc.
3.You can choose different size glass bead between 50μm-1180μm according to different function.

3) Technical references
Appearance: Colourless and transparent ball, no visible bubbles and impurity.
Spherical beads:≥80%(600< Sieve size< 850um
spherical beads≥75%)
Density:2.4-2.6g/cm3
Refractive index:Nd≥1.50
 
Glass bead composition:The glass bead is made of sodium and calcium. SiO2
68%

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.

B.Coated Glass Bead.

Product Introduction
    The coated glass bead have been treated with high quality organic materials on their surface, thus bearing better features in quality. Our company has developed this unique product after absorbing advanced technology from foreign countries and it has the following advantageous 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.

Product specification
Coated can be done from 50μm-1180μm, based on clients requirements.

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 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:
