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 hollow-glass microsphere? Hollow glass microspheres are also called microballoons. Their diameter can range from 10 micrometers to 300 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. It's a new type of micron grade light material, developed in 1950s and 60s. Its primary component is borosilicate. The particle size of the material is 10250mm with a wall thickness 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 wall thickness determines the compression strength of the hollow ball. As is expected, this strength increases with the density. 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
Glass powder can be used to create a glass product by passing pre-prepared powder through a flame heated between 1100-1500°C. Due to the increase in solubility, SO3 as well as other gases in the glass are released from the inside due to the change in atmosphere. The surface tension of the glass powder causes it to become spherical at high temperatures. The spillage gas forms hollow glass beads when it is sealed within the spherical particle.
2. Spray Granulation Method
Spray granulation is made with aqueous sodium silicate solution containing a special auxiliary agent (boric, urea or ammonium pentaborate), and through the nozzle, solution injection is injected into a spray dryer. It is expected that the powder particles will drop in size after drying, leading to hollow glass beads formed by powder particles heating foam.
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. The glass beads are then sprayed onto the spray dryer tower after being mixed.
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, low-density concrete, bowling, sealing material. lightweight, resin, handicrafts, wall plate sandwich layers, lightweight packaging, electronic industry.
Hollow glass microspheres are also coated to provide a conductive surface. Conductive coatings optimized in thickness give spherical materials excellent shielding and conducting properties while retaining the weight savings of hollow, low density materials. 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 good reprocessing properties. It is used in the manufacture of composite materials like wood, engineering plastics, insulation material, 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.
