Hollow glass balls are hollow spherical powdered materials that are non-metallic and inorganic. Their particle size is 5-100mm with a wall-thickness of 1-2mm. The compressive strength ranges from 3-125MPa.

The following is a list of the most recent articles about Hollow Glass Beads Sphere Hollow Glass Beads : What is a hollow glass microsphere (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 foam or lightweight cement. 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. It's a micron grade light material, developed in 1950s and 60s. Its primary component is borosilicate. The particle size ranges from 10250mm to 12mm. Hollow glass beads feature high compressive strengths, high melting points, high resistivity as well as low thermal conductivity.
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 compressive strength is determined by the thickness of the hollowed sphere. This, in turn, is influenced by the density. Hollow glass sphere Chemically stable, nonflammable, and nonporous. Excellent water resistance. It is a trusted worldwide brand. Hollow Glass Beads Sphere Hollow Glass Beads You can also contact us by clicking here. .

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.

What are Hollow Glass Beads Sphere Hollow Glass Beads Produced?
How do you make microspheres of glass?
1. Glass powder method
Using pre-prepared powdered glass containing SO3 and passing it through the flame between temperatures of 1100-1500 is the glass powder method. Due to a decrease in the solubility, and a change in the atmosphere inside the kiln's atmosphere, SO3 or other gases dissolved into the glass are now escaping from the interior of the powder. Surface tension causes the glass powder to become spherical at high temperatures. The gas leakage is sealed inside the spherical powder to form hollow beads.
2. Spray granulation is a method of granulation.
Spray granulation is a method that is done in advance using a special auxiliary (boric, urea or ammonium pentaborate). The solution is injected into the spray drying machine, which is expected to dry to a specific particle size.
3. The droplet method
The liquid drop technique uses the same raw material as the spray-granulation method. The raw materials used are 500 copies each of sodium silicate (M(SiO2):M (Na2O =2) and 10% ammonium aqueous solution. 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 at 1280 in a vertical electric oven.

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, low-density concrete, sealing material and lightweight. Other uses include resin handicrafts such as the wall hanging frame for murals, sandwich layers of lightweight packaging material on wall plates, electronic industry (such as lightweight concrete), absorbing materials, and lightweight concrete.
Hollow glass microspheres are also coated to provide a conductive surface. This coating provides spherical materials with excellent shielding properties and conductivity while maintaining weight savings. These conductive microbubbles can be used for a variety of applications including military, biotechnology medical devices, electronic and other industries.
Hollow glass beads can reduce weight and improve sound insulation. The products are also resistant to cracking and have good 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, communications, new high-speed cars, ships and in the aerospace and communication industries.
