Hollow glass balls are hollow spherical powdered inorganic nonmetallic materials with a particle-size of 5-100mm. The wall thickness is 1-2mm. Their compressive strength is 3-125MPa. The following is a list of the most recent articles about Holl...…
"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 ...…
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...…
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...…
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....…
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...…
The evolution of the tensile strength, the tensile modulus, and the elongation at the break of the three samples. Firstly, it is necessary to say that the results of the tensile test following those reported by other authors for the neat PA2200 [16,1...…
Regarding the thermal information obtained from DSC analysis, Table 3 shows a single melting peak, Tm, around 185℃ belonging to the three materials' γ-crystal phase of polyamide. Similarly, the crystallization peak, Tc, coincided at ∼140℃for all mate...…
The matrix material PA2200, with an average particle size of 60μm and a white appearance, was obtained from EOS GmbH in Germany. Moreover, the mixing ratio of new and old powder is 1:1. Filler additives, Hollow glass powder was surface treated with s...…
Hollow glass powder (HGM), mainly composed of borosilicate glass, is an important inorganic filler with low density, high-temperature resistance, good fluidity, heat insulation, and good thermal stability. Through surface modification, HGB is applied...…
Selective laser sintering (SLS) to prepare composites by adding filler into the polymer effectively saves costs and reinforces the sintered parts. This article investigated the fabrication of PA2200 composites filled with different volume fractions o...…
What is Hollow glass powder?The hollow glass powder is a micron-sized hollow glass microsphere with a smooth surface. The main chemical component is borosilicate glass, a hollow transparent sphere under an electron microscope. Hollow glass beads have...…
The full name is indium phosphide. Indium phosphide is a chemical substance, dark gray crystals with pitch luster. It is made by heating and reacting metallic indium and red phosphorus in a quartz tube and used as a semiconductor material. Indium pho...…
In the field of mechanical parts machining industry, plastics are often used as raw materials for further machining. Now there are many types of plastics on the market.…
The Rhine, which flows through Switzerland, Germany, France and the Netherlands, is an important shipping channel in Europe, and tens of millions of tons of goods are transported between countries through the Rhine every year. The persistent drought…
