Road reflective glass beads is a kind of glass sand as a raw material tiny glass beads formed through high temperature melting observed spherical, colorless and transparent under the microscope, a refractive index of between 1.5-1.64 diameter general between 75 micrometers to 1400 micrometers. It is also called reflective glass beads.Currently in the domestic production of road reflective glass beads craft flame floating method and electric melting method.

Road reflective glass beads for road marking as the reflective material to improve road marking paint Retroreflective performance, improve traffic safety at night, has to be determined for national transport sector.When driving at night, the lights shone on road signs online with glass beads, can lights and parallel light rays reflected back so that drivers see the way forward to improve traffic safety at night. Now, reflective glass beads have become a road safety products reflective material can not be replaced.

Reflective glass microspheres is a tiny glass sphere glass sand particles as raw material formed by high-temperature melting. Reflective glass microsphere for road marking as the reflective material to improve road marking paint Retroreflective performance, improve traffic safety at night, has to be determined for national transport sector.When driving at night, the lights shining on the road signs with glassmicrosphere, can lights and parallel light is reflected back, never make drivers see the way forward to improve traffic safety at night. Now, reflective glass microspheres have become a road safety products reflective material can not be replaced.

Ocean is a treasure trove of resources and energy, especially deep-sea fields. Currently, deep-sea exploration, development mainly in diving technology, the use of submersible, underwater robots in the deep sea observation, measurement, sampling, install the necessary instruments and facilities, underwater operations. High strength solid buoyant material is an important part of modern diving technology, to ensure the buoyancy of submersible, submersible increased payload, reduce its dimensions, has an important role.
With increasing dive depth, pressure increased dramatically deteriorating environmental conditions, so the sharp increase diving solid buoyant material performance requirements, especially in terms of compressive strength.Generally, improving the compressive strength of the foam density increases often result. But for buoyancy material, density is a very important performance index, which directly affects the buoyancy materials, namely payload capacity.It means lower density increases buoyancy, increased excessive or even lose buoyancy. Thus, advanced solid buoyancy material should be both light and strong, i.e., maintaining a low density, the substantial increase in the compressive strength.Advanced solid buoyant material preparation technology, mainly for the United States, Russia and other countries to master the material density is generally in 0.4 ~ 0.6g / cm3, compressive strength at 40 ~ 100MPa.While in the field of research has been carried out for many years, but dive with solid buoyancy material properties are also poor, heavily dependent on imports. Factors behind this situation are many, the core raw materials – the lack of high-performance hollow glass microspheres is a key factor.

Currently, it makes microwave radar, infrared, radar or other electromagnetic wave radar and acoustic detection system shield absorbing materials have been widespread concern in the military field. Near infrared reflective material can be used in aviation, aerospace, building materials, vehicles, weapons and other fields.
Cenospheres powder density is small, the metal surface after its treatment, can be substituted for the denser metal electromagnetic wave absorbing powder (RAM) or prepared electromagnetic shielding (EMI) material.

Hollow glass beads, high temperature, corrosion resistance, low creep, good quality of light and chemical stability, excellent mechanical properties and thermal physical properties, get in the building materials, plastics, rubber, paint, and other fields are widely used. Through the hollow glass microspheres surface modification, plated with a layer of metal that can make it conductive or electromagnetic wave absorption performance.

Chemical plating method in the surface of hollow glass microspheres silver plated layer of metal, it is possible to have good conductivity, the conductive rubber can be used as an electromagnetic shielding conductive filler.

The mixture of hollow glass beads:
The hollow glass microballoon filled quantity generally between 5% and 20%. Hollow glass beads are easily mixed with resin, the general advice under the mixing speed of slower in the last stage of the hybrid hollow glass beads. If you must use the high pressure pump, it must be determined in advance the strength of the hollow glass microballoon whether meet the requirements.

Light weight; bulky
Hollow glass microspheres density of about one dozen points of traditional filler particle
density, after filling can greatly reduce the weight of the base product, alternative and
save more resin production, reduce product cost.

Has organically modified (lipophilic) surface
Hollow glass beads wetting and dispersing readily be filled in the most thermosetting
thermoplastic resin, such as polyester, epoxy, polyurethane and the like.

High dispersion, mobility
Since the hollow glass microspheres are tiny balls, the liquid resin than the sheet-like,
acicular or irregular-shaped filler even with good fluidity, so that excellent filling
performance. More importantly, such a small bead is isotropic, it does not produce a
result-oriented in different parts of the shrinkage caused by inconsistent ills, ensure
that the product is dimensionally stable and will not warp.

Insulation, sound insulation, insulation, low water absorption
Internal hollow glass microspheres is rarefied gas, so it has the characteristics of noise,
heat, and is used as a variety of insulation, excellent sound insulation filler products.
Thermal insulation properties of hollow glass microspheres can be used to protect the product
is subjected to alternating between heat and quench emergency conditions caused by thermal
shock. Higher specific resistance, low water absorption so that it can be widely used in
processing the cable insulation.

Low oil absorption
Spherical particles determines the minimum specific surface area and low oil absorption,
use of the process can significantly reduce the amount of resin, even under the premise of
a high added amount of the viscosity is not increased much, greatly improved the production
operating conditions, production efficiency increased by 10% to 20%.

Academy of fine glass beads by using self-developed surface modification agents and complex process, so that the hollow microspheres can be uniformly dispersed in the polymer matrix, microbeads and a substrate with good interfacial bonding, resulting in overall performance high ultrafine hollow microsphere / polymer composite.

It is understood that, with 20% of cenospheres modified PP compared with pure PP, notched impact strength increased by 80% to 100%, tensile modulus, flexural modulus of more than 50 percent, also improved flexural strength only tensile strength remained unchanged or a slight decline. Ultrafine inorganic hollow microsphere belong, wear resistance than polypropylene. In addition, it has a reflex action of ultraviolet, UV can improve performance composites.

Fill the hollow glass microballoon artificial wood for making furniture parts, accessories and sculpture to provide excellent quality assurance. In the original recipe adding different proportions of hollow glass beads, can adjust the product density.The oil absorption rate of the hollow glass microspheres is much smaller than calcium carbonate and so on ordinary packing, can make the viscosity dropped significantly. Compared with the traditional mineral additives, the hollow glass beads have better liquidity, applicable to the manufacturing area is large, thin plate, after adding the hollow glass beads material more nailing processing, changed the traditional formula of artificial wood is common after nailing cracking phenomenon.
