Alkali Metal Silicate Containing Patents (Class 106/600)
  • Patent number: 11118107
    Abstract: A treatment additive for hydraulic fracturing made of heated silica to create amorphous silicate with a Mohs hardness between 4.5 and 6 and a particles distribution with maximum diameter between 5 and 2600 microns that has been heated and shaped into amorphous shapes with large surface area to weight ratio and ultra-low settling velocity used to prop microfractures distal from well bore, especially in low viscosity and high temperature wells. The microparticle size and shape allow the treatment to effectively hold microfractures open, stimulate backpressure, and prevent leakoff; which has the added benefit of improving primary fracture development; refrac and frac protect productivity; and reduces the likelihood of interference between offset wells. An additional benefit is that the treatment doesn't contain crystalline silica.

  • Patent number: 10697634
    Abstract: An annular combustor includes an inner liner shell and an outer liner shell defining an interior volume through which combustion gases flow in a gas flow direction from a forward end to an aft end. A cooling shroud is attached radially outward of the inner liner shell, forming a cooling passage between the inner liner shell and the cooling shroud. The cooling passage directs air in an air flow direction opposite to the gas flow direction. The cooling shroud is assembled from circumferentially adjoined cooling shroud segments, and the distance between the cooling shroud segments and the inner liner shell is greater at the forward end than at the aft end. Fastening elements are distributed across an axial length of the cooling shroud segments in circumferentially staggered rows. Each forwardmost fastening element is disposed immediately adjacent to a curved portion at the forward end of each respective cooling shroud segment to reduce vibration.

    Abstract: Cementitious compositions and methods of synthesis are disclosed. By decreasing the Ca-rich raw material in a cement composition, the content of Alite (Ca3SiO5) per ton of produced cement can be mitigated. Alite is the most energy-intensive and most polluting component among cement ingredients. By decreasing this component, the process can potentially reduce the environmental footprint and energy consumption by as much as 12% per ton of cement. In one embodiment, the average Ca/Si ratio in hardened cement paste can be reduced from ˜1.7 to ˜1.5. This corresponds to about a 12% reduction in Alite content per ton of produced cement. The cement compositions can also be characterized as solid-state cement hydrates including a plurality of silicate chains, the plurality of silicate chains including a plurality of dimers constituting at least about 60% of the plurality of silicate chains present in the solid-state cement hydrate, the plurality of dimers enhancing the strength of the solid-state cement hydrate.

  • Publication number: 20120247369
    Abstract: A novel binder system comprising at least one latent hydraulic binder, at least one amorphous silica, optionally at least one reactive filler and at least one alkali metal silicate is proposed. It was surprisingly found that the binder system according to the invention hardens in the form of a hybrid matrix which is acid-resistant, water-resistant and alkali-resistant. The binder system can be used for the production of a hydraulically setting mortar which, after setting, hardening for seven days and subsequent storage for three days in acid, base and/or water, has compressive strengths of more than 15 N mm?2, preferably more than 20 N mm?2 and in particular more than 25 N mm?2, according to DIN EN 13888.

  • Publication number: 20120085263
    Abstract: Hydraulic cements, such as Portland cements and other cements that include substantial quantities of tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate (C3A), and/or tetracalcalcium alumino-ferrite (C4AF), are particle size optimized to have increased reactivity compared to cements of similar chemistry and/or decreased water demand compared to cements of similar fineness. Increasing hydraulic cement reactivity increases early strength development and release of reactive calcium hydroxide, both of which enhance SCM replacement and 1-28 day strengths compared to blends of conventional Portland cement and one or more SCMs, such as coal ash, slag or natural pozzolan. Decreasing the water demand can improve strength by decreasing the water-to-cement ratio for a given workability. The narrow PSD cements are well suited for making blended cements, including binary, ternary and quaternary blends.

  • Publication number: 20120077040
    Abstract: The present invention relates to a heat dissipation coating agent and to a heat-dissipating plate including same, which efficiently dissipate heat from the surface of a heat-dissipating plate of an electric/electronic component. Particularly, the heat dissipation coating agent, which is applied to the surface of a heat-dissipating plate of an electric/electronic component, includes infrared radiation powder and a binder, and the heat-dissipating plate is coated with a heat dissipation layer consisting of the heat dissipation coating agent. Since the heat dissipation coating agent applied to the heat-dissipating plate is highly conductive, heat is emitted from the heat-dissipating plate by conduction as well as convection. In particular, the heat dissipation coating agent, which conducts heat with high conductivity, can be applied to a heat-dissipating plate of a high-power LED light source.
