Hollow glass microspheres as measured by a gas pycnometer

"Average density" is the quotient obtained by dividing the mass of a sample of hollow glass microspheres by the true volume of that mass of hollow glass microspheres as measured by a gas pycnometer. "True volume" is the aggregate total volume of the glass bubbles (not the bulk volume); "glass" refers to all synthetic amorphous inorganic solids or melts that can be used to form amorphous solids, where the raw materials used to form such glass includes various oxides and minerals; "HOLLOW GLASS MI

The energy consumption required to manufacture HOLLOW GLASS MICROSPHERES POWDERs

The energy consumption required to manufacture HOLLOW GLASS MICROSPHERES POWDERs, as described in Examples 1-4 of U.S. Patent No. 4,391,646 (Howell), can range from about 8 to about 50 kW-h per kg of product made. While commercial processes operating at a larger scale are more efficient, they still tend to use more than 5 kW- h per kg of product. Provided here are improved energy-efficient processes for producing HOLLOW GLASS MICROSPHERES POWDERs having high strength-to-density ratios compared w

HOLLOW GLASS MICROSPHERES POWDER will solidify before it can burst

Attempts to form monocellular HOLLOW GLASS MICROSPHERES POWDERs from a feed comprising a blowing agent using electrical furnaces were not successful because the short residence times used in a flame-forming process could not be attained. That lack of control on the time scale means that forming conditions can only be optimal for a part of the particle size distribution, so HOLLOW GLASS MICROSPHERES POWDER yields tend to be low. To overcome the delicate balance between glass melt viscosity and pr

Method of making hollow glass microspheres

HOLLOW GLASS MICROSPHERES POWDERs have widespread applications in many technologies, including buoyancy modules, density modifiers for drilling fluids, cement, explosives, thermosets (including adhesives and coatings), molded polymeric products (e.g., rubber and thermoplastic parts), and thermal insulation including cryogenic or heat applications, for example, in pipes, tanks or buildings. Despite the multitude and size of the markets into which HOLLOW GLASS MICROSPHERES POWDERs have penetrated,

HOLLOW GLASS MICROSPHERES POWDERs

Hollow glass microspheres ("HOLLOW GLASS MICROSPHERES POWDERs"), also referred to as "glass bubbles," are balloon-like glass structures having a median diameter of fewer than 500 micrometers. HOLLOW GLASS MICROSPHERES POWDERs are currently made using a process where a milled glass powder (or "glass frit") that contains a suitable blowing agent is flame-heated to temperatures at which the glass begins to soften. At these temperatures, the blowing agent either becomes or produces a gas, causing th

Hollow glass powder to Develop high strength concrete

What is Hollow glass powder?Hyundai E&C said it had developed the world's first high-strength concrete with reduced viscosity by utilizing hollow glass powder. It is possible to significantly reduce the viscosity of concrete with only a small amount of hollow glass powder and secure workability easily because external temperatures do not affect it. The builder has verified the excellent performance of high-strength concrete with a compressive strength of up to 80MPa through field demonstration.

What is the thermal conductivity of hollow glass microspheres

The conductivity was found to be 0.65–0.77 W/m·K, and the density was 0.4–0.46 g/cm3. Glass typically has a tensile strength of 7 megapascals (1,000 psi). However, the theoretical upper bound on its strength is orders of magnitude higher: 17 gigapascals (2,500,000 psi). This high value is due to silicon dioxide's strong chemical Si–O bonds. Hollow glass microspheres have numerous advantages, such as insulation, consistency, resistance, gloss, etc. No other material can provide a complete substit

What are the applications of hollow glass microspheres

What is Hollow glass?Hollow glass microsphere technology was developed in the 1950s as an outgrowth of the manufacture of solid glass beads. Hollow Glass Microspheres (HGMS) are near-perfect engineered spherical bubbles of thin-walled glass, approximately 50 microns in size, with a low density of between 0.1-0.4 g/cc. The glass type is amorphous and can come with low-purity or high-purity grades. Hollow glass microspheres are used to achieve high levels of Total Solar Reflectance (TSR) in coatin

Luminescent material of Zinc sulfide

Zinc sulfide (or zinc sulfide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white and widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent and is used as a window for visible and infrared optics. ZnS exists in two primary crystalline forms. This dualism is an exam
