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 ("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...…
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 ...…
Some depression glass is uranium glass. Although of marginal quality, Depression glass has been highly collectible since the 1960s. Due to its popularity as a collectible, it is becoming more scarce on the open market. Rare pieces may sell for severa...…
What is Hollow glass powder?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 wi...…
Soldering is a technique for joining metal parts together. It involves melting a metal called solder in the space between two metal assemblies.…
Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 nex…
