The hollow glass bead is a kind of small, hollow spherical powder. The particle size can be1-500Any choice between micrometers, density in0.1 -0.3 g/cm3. It has the advantages of lightweight, large volume, low thermal conductivity, high compressive strength, good dispersion, fluidity, and stability.
In addition, it has excellent performance of insulation, self-lubrication, sound insulation, nonwater absorption, fire resistance, corrosion resistance, radiation protection, non-toxic, etc.
This product can be directly filled in most types of thermosetting and thermoplastic resin products, reduce product weight, reduce cost, eliminate the internal stress of products, ensure dimensional stability, improve compression resistance, impact resistance, fire resistance, sound insulation, insulation, and other functions!
Some expensive filling materials such as bronze powder, molybdenum disulfide, and silica can also be replaced. Hollow glass beads are made of inorganic materials.
According to chemical composition: silica, alumina, zirconia, magnesium oxide, sodium silicate, etc. It has a particle size of 10 to hundreds of microns and a wall thickness of several microns, filling the interior CO2A closed microsphere of equal gas.
The product performance index reaches the leading level of similar products in China. It has the advantages of a lightweight, low heat conduction, non-toxicity, non-combustion, good chemical stability, and high dispersion. It is artificial marble, fiberglass, atomic ash, paint, plastic, chemical, building materials and other industries excellent product fillers.
I think we all know about glass beads, but you also know very little about the products of glass bead manufacturers. Glass bead factories use glass bead furnaces to produce high-strength glass beads, but there are other rare products, which are made by different processes.
There are common road reflective glass beads, which can be seen on the road warning signs. Sandblasting glass bead is to hit the surface to be treated by high-speed sand. Its main function is to make the surface of the workpiece rough. Shot peening glass bead is a kind of spherical particle, which is commonly used in medical devices and hardware products. Next is a rare one.
Nano glass beads, as the name implies, is a kind of nano product, which can have some special uses. Because of its high reflective index, a high reflective index glass bead is mainly used in reflective materials, and it can also be seen in air flat top reflective materials.
Glass beads manufacturers will have glass beads wholesale, not only regular products but also coated glass beads, ultrafine glass beads, and other rare products wholesale. If you want to know more about the products, you can make relevant inquiries and learn about the products you don't know.
TENROAD reflective glass beads refer to the high-grade products with large particle size, high roundness, high inversion and visible on a rainy night in the latest international standards for glass beads.
TENROAD reflective glass bead for road marking paint adopts new"Glass melting granulation"The process production is to melt the specially prepared optical material into glass liquid, then draw the glass liquid into glass rod according to the required particle size of glass bead, and then carry out high-temperature cutting and granulation. The glass bead produced by this process has an excellent performance in roundness rate, purity, transparency, evenness, coating layer, and other aspects. The marking line of using this glass bead construction Compared with the traditional markings, the coefficient of retroreflection is greatly improved (the highest ≥800mcd/lux/m2）And with certain visibility of rainy night, it has become a veritable all-weather marker.
