摘要:
There is provided a composition comprising a slurry of capsules, the capsules having shells comprising silica and said shells encapsulating phase change materials (PCM); and a cementitious binder. There is also provided a method for preparing said composition.
摘要:
The present invention provides methods of producing manufactured aggregates and other compositions from an encapsulated PCM slurry, suspension or emulsion by combining a cementitious binder and a adsorbent and/or absorbent with the PCM slurry. The encapsulated PCM-containing composition can be produced in an agglomeration process. The ingredients can also be mixed to form a viscous mass which can be extruded or otherwise formed to produce useful products.
摘要:
The present invention provides methods of producing manufactured aggregates and other compositions from an encapsulated PCM slurry, suspension or emulsion by combining a cementitious binder and an adsorbent and/or absorbent with the PCM slurry. The encapsulated PCM can be introduced as damp cake or dry form as alternatives to the liquid forms. Fire resistant aggregates can be produced in an agglomeration process. The ingredients can also be mixed to form a viscous mass which can be extruded or otherwise formed to produce useful products.

摘要:
The present invention provides a method and compound fabric for latent heat effect which means a compound fabric capable of undergoing heat storage (release) material for microcapsules with waterborne polyurethane shell which use interfacial condensation polymerization by waterborne polyurethane thereof, such as alkyl alkyrate (alkyric acid alkyl ester) for temperature in the range of 0null C. to 80null C. The fabric is selected from the group of consisting of woven, non-woven and structure of woven, and the present invention provides method to coat waterborne polyurethane shell microcapsules of heat storage (release) material for compound fabric
摘要:
The present invention relates to a powdered mix of a phase change material blend. The blend includes a polar phase change material bound substantially to at least one surface of a clay matrix having a surface charge, wherein the blend is present in a powdered form at temperatures above and below the phase change temperature of the polar phase change material. The present invention also relates to a method of making the powdered mix of a phase change material blend and a therapy pack including the powdered mix of a phase change material blend.
摘要:
A method for fire retarding porous products used for thermal energy storage and products produced thereby is provided. The method includes treating the surface of the phase change material-containing porous products with a urea fire-retarding agent. Upon exposure to a flame, the urea forms an adduct with the phase change material which will not sustain combustion (is self-extinguishing) in air. No halogens or metal oxides are contained in the fire retardant, so no potentially noxious halide smoke or fumes are emitted if the product is continuously exposed to a flame.
摘要:
A high-strength geopolymer hollow microsphere, a preparation method thereof and a phase change energy storage microsphere are provided, including: dissolving sodium hydroxide, sodium silicate and spheroidizing aid in water to form a solution A, and adding active powder to the solution A, stirring and uniformly mixing to form a slurry B, adding the slurry B to an oil phase, stirring and dispersing into balls, filtering to obtain geopolymer microspheres I, washing the geopolymer microspheres I, and then carrying out a high-temperature calcination to obtain the high-strength geopolymer hollow microspheres II; using the high-strength geopolymer hollow microsphere as a carrier, absorbing a phase change material into the carrier, and mixing a microsphere carrying the phase change material with an epoxy resin, adding a powder dispersant and stirring to disperse the microsphere, after the epoxy resin is solidified, screening the superfluous powder dispersant to obtain the phase energy storage microsphere.
摘要:
A method of fracturing a subterranean formation comprising: introducing a fracturing fluid into the subterranean formation to create or enhance one or more fractures in the subterranean formation; introducing a cement composition into the one or more fractures, wherein the cement composition comprises: (A) cement; (B) water; and (C) an additive; and allowing the cement composition to set, wherein the additive creates a plurality of pores within the set cement.
摘要:
The present invention relates to an inorganic board comprising a base layer containing magnesium-based inorganic materials and phase change materials, and to a method for producing the board. The inorganic board of the present invention employs magnesium-based inorganic materials instead of plaster used in conventional boards, and thus improves the strength and water resistance thereof as compared to conventional plaster boards. Accordingly, the board of the present invention is formed so as to be thin, and the content of the phase change materials in the base layer increases by the superior blending ratio of magnesium-based inorganic materials and phase change materials, thus maintaining the indoor temperature of the structure constructed by the board of the present invention at a comfortable level. Therefore, the inorganic board of the present invention can be effectively used in interior materials or the like for a building, which require strength and water resistance properties.
