Hollow glass balls are hollow spherical powdered inorganic nonmetallic materials. Their particle size is 5-100mm with a thickness of 1-2mm. The compressive strength is 3-125MPa.

The following is a list of the most recent articles about Hollow Glass Beads Sphere Hollow Glass Beads : What is hollow Glass Microsphere? Hollow glass microspheres are also called microballoons. Their diameters range from 10 to 30 micrometers. Hollow spheres fill composite materials like lightweight concrete, syntactic elastomer and foam. The hollow spheres can be used to fill lightweight composite materials like syntactic polymer foam and lightweight concrete. Hollow glass bead This is a special type of glass bead that is less dense and has a lower thermal conductivity. This new micron-graded light material was developed during the 1950s and 60s. Its primary component is borosilicate. The particle size is 10250mm with a wall thickness 12mm. Hollow glass beads feature high compressive strengths, a high melting temperature, a high resistivity, a low thermal conductivity coefficient and small thermal shrinkage coefficient.
Hollow glass microspheres Micro balloons (also known as bubbles) are formed from borosilicate and sodium salt glass mixtures. They have low density, and they're resistant to heat and chemicals. The walls are made of Glass microspheres The spheres are typically rigid and about 10% thicker than their diameter. Spherical particles are available in a variety of densities ranging from 0.06g/C3 to 0.80g/C3, and particle sizes from 5um to180um. The wall thickness determines the compression strength of a hollowed sphere. This is expected as the density of a sphere will increase with increasing wall thickness. Hollow glass sphere Chemically stable, nonflammable, and nonporous. Excellent water resistance. It is a trusted worldwide brand.

Hollow Glass Sphere Hollow Glass beads Product Performance:
Hollow glass microspheres consist of hollow glass microspheres at the micron level with a smoothed surface. It is made up of borosilicate, which is the main chemical component. The sphere is hollow and transparent under an electron microscope. Hollow glass beads possess low density, good strength, resistance to acid and alkali, low thermal conductivity and electrical insulation, among other qualities. These new materials are multifunctional, have high chemical stability and fluidity.

How can you tell? Hollow Glass Beads Sphere Hollow Glass Beads Produced?
How do you make microspheres of glass?
1. Glass powder method
In the glass powder method, pre-prepared powdered glass containing SO3 is passed through the flame between temperatures of 1100-1500. Due to the decreased solubility of SO3 in the glass and the changes in atmosphere, the SO3 and other gas dissolved within the glass powder begin to overflow. The surface tension of the glass powder causes it to become spherical at high temperatures. The gas leakage is trapped in the spherical glass particles, forming hollow glass beads.
2. Spray granulation is a method of granulation.
Spray granulation is made with an aqueous sodium silicate solution containing a special auxiliary agent (boric, urea or ammonium pentaborate), which is injected through the nozzle into the spray drying machine. After drying, it is expected that powder particles will fall to a specific particle size.
3. The droplet method
The liquid drop technique uses the same raw material as the spray-granulation method. The same amount of 10% ammonium-perborate aqueous solutions is added as well as 500 copies each of sodium silicate. After evenly mixing, the hollow beads are sprayed onto the spray dryer tower.
4. Dry gel method
The alkyl sodium was added to dilute Hydrochloric Acid and decomposes with water. After gelation, gel was dried twice at 60°C and 150°C and then crushed in a ballmill. After grading was completed, dried gel powder was obtained. This was then foamed up in an electric vertical furnace at 1280.

Applications Hollow Glass Beads Sphere Hollow Glass Beads :
Hollow glass microspheres have many applications, including glass fiber reinforced products, composite foam, artificial wood, compound, sound insulation, heat preservation, atomic-ash, bowling and low-density concrete. Other uses include sealing material, lightweight materials, resin crafts, wall-mounted hanging frames, wall-plate sandwich-layer structure of lightweight packaging material, electronic industry.
Hollow glass microspheres are also coated to provide a conductive surface. Conducive coatings of optimal thickness are used to give spherical materials excellent shielding and conducting properties, but still maintain the weight savings that come with hollow low-density material. These conductive microbubbles can be used in military applications, biotechnology and medical devices as well electronics.
Hollow glass beads can reduce weight and improve sound insulation. The products are also resistant to cracking and have excellent reprocessing properties. It is used in the manufacture of composite materials like wood, engineering plastics, rubber, buoyancy materials, FRPs, artificial marbles, man-made stones, the oil and gas industry, aerospace and communications, new high-speed cars and ships, thermal insulation coatings and adhesives.
