Weight reduction filler Hollow Glass Microspheres is a tiny sphere with high ball-type rate. Its ball-bearing effect can improve its mobility and reduce the viscosity and internal stress of resin mixture. Therefore, during processing, less heat is produced in composite materials so as to prevent inadequate lubrication and partial thermal decomposition. It is more likely to extrude when molding, which can not only reduce defects in products, but also improve the production efficiency by 15% -20%.

Type III – High Index of Refraction of reflective Glass beads are used to airfield marking paints. The Glass Beads are highly reflective 1.9 index glass beads that are 80%+ round. They are made using a unique and revolutionary manufacturing process along with the purest of raw materials. The quality and uniformity of the High Index Glass Beads ensure outstanding performance on the airport runways. Type III – high index glass beads for drop-on applications are intended for applications where increased retro-reflectivity is needed.

The high-performance hollow glass microspheres, a kind of ultra-light inorganic non-metallic powder with hollow “ball-bearing” shapes, have been developed into a new type of high performance lightweight material and have been widely applied in recent years. It will be the main direction for new-type compound materials in the 21st century. Its true density is 0.15-0.60 g/cm3; particle size is 5-180μm; Due to its excellent advantages of light weight, bulk density, lower thermal conductivity, higher compressive strength, improved dispersion and liquidity, and excellent chemical stability, it can be used as filler in painting, rubber, plastics, glass steel, man-made stone, putty, exploitation of oil and gas and other materials.
Glass beads for sandblasting has the features of chemical stability, high mechanical intensity and hardness. They can be blasted 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.

We can not only produce common glass beads, but also developed coating technology. The coated glass bead is a new product of glass beads developed in recent years,which is used for road graticule surface spreading. With the excellent charcteristics,the great majority of users have paid more attention to it .
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:
Glass beads surface coating is not easy to be eroded. In the process of storage and usage, glass beads whose surface is easy to be moisture is in humid atmosphere, It leads to light scattering,and therefore influences the direct reflection.
Glass beads coated material is a kind of organic material which may have better consolute with road coating material. While being spread on the road graticule surface,it is not easy to come off, It has stronger adhesion force specially used on coating material graticule of constant temperature (including water soluble coating material)and may maintain light reflection effects for a long time.
Coated glass beads has better adhesiveness with road coating material,particle sedimentation can be controlled after surfacer spreading through reasonable galss beads particle grading so as to ensure better reflection effect of the graticule.
Coated glass beads has good fluidity,with the characteristic of non-blocking. mean spreading,easy construction and good reflection effect.It is proved practically that it can save about 15%usage amount.

Glass beads are fired through the glass sand. Glass beads can be divided according to the size of the glass bubble (glass bubble is a glass bead, referring to a particle size of 1mm or less solid sphere) and glass beads. By applications can be divided into reflective glass beads, sand blasting with glass beads, glass polishing beads, filled with glass beads. Reflective glass beads which can be divided into safety classes reflective glass beads and silver screen with glass beads; by the refractive index to points, can be divided into ordinary refractive index and high refractive index glass beads. Usually a refractive index of between 1.5-1.64, a high refractive index is generally 1.8-2.2. If, as is most appropriate to use reflective glass beads refractive index of 1.93, the refractive index can be perfectly parallel rays refracted back, so it is not the best reflection refractive index higher. According to the shape of points can be divided into rules and irregular glass beads glass beads. Divided by color can be divided into a colorless, transparent colored glass beads and glass beads.
Endothermic temperature drops, the water acts as a foaming agent to the surface of the glass powder agglomeration, concentrated sodium silicate to the surface, forming shell beads from glass powder and water glass preform formed. Semi-finished beads tower sintering furnace, after melt, foam and annealing process is finished baking beads.
Product Function
Reflective glass beads can improve the retro-reflection property of the road marking line. Driving at night, the headlights shines on the road marking line with glass beads, the light of headlights is reflected back parallelly. so the driver can see the road ahead clearly, and drive safely at night.
