H ® Road Marking Drop-on Top Reflective Glass Beads Same As Potter's
High lightness glass beads for Drop-on road marking
GANGDE has launched high quality H series glass beads since 2015, with GANGDE's wisdom and profession.We choose raw material strictly, with advanced technology and QC to make sure quality, achieving success after 300days. H series have high brightness and roundness charateristic, which can be widely used in road marking and blasting field,making up the weak point of whole industry,over twice brighter than regular glass beads.
H series is made of special optical structure and has similar appearance to ordinary reflective glass beads. However, the advantage of glass beads lies in improving the inversion coefficient of road markings to more than 500 MCD, which is far more than the performance of ordinary glass beads (the inversion coefficient of ordinary glass beads is generally about 300 MCD). Experts say that H glass beads have the same effect as Potter glass beads in the United States, and they are the top glass beads with the best anti reflection effect and the best cost performance ratio. It is suggested to popularize and use it.
Advantage of our glass beads
200times magnification microscope view of glass beads,produced by GANGDE's float-vertical tech, with final bead's surface smooth and shining.
Reason：Natural gas is clean energy, which can provide stable calorific value and high energy. It can bring shining surface for glass beads,and the rate of finished products yield is higher, with good quality too. After 11 long and complex technologies, we produce high roundness, high cleanliness and high whiteness bright glass beads. To this day, we have not found any new manufacturer that can provide such products in China.
Shortcoming of other supplier
200times magnification microscope view of glass beads,produced by regular lie-rotate method,final bead's surface rough and dim.
Reason：The conventional technology to produce glass beads with high roundness, and producers usually use the rotation method to produce glass beads. In the process of manufacturing glass beads, lime powder, carbon powder and other powder will be produced, which will cause great pollution to people and the environment.
Indispensable raw material: sulfuric acid. It will corrode the surface of glass beads and pollute the environment. Sulfuric acid will always adhere to the surface of glass beads.
