43174 results about "Thermal insulation" patented technology

Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.

Phase change material thermal capacitor clothing

An apparatus and method for metabolic cooling and insulation of a user in a cold environment. In its preferred embodiment the apparatus is a highly flexible composite material having a flexible matrix containing a phase change thermal storage material. The apparatus can be made to heat or cool the body or to act as a thermal buffer to protect the wearer from changing environmental conditions. The apparatus may also include an external thermal insulation layer and/or an internal thermal control layer to regulate the rate of heat exchange between the composite and the skin of the wearer. Other embodiments of the apparatus also provide 1) a path for evaporation or direct absorption of perspiration from the skin of the wearer for improved comfort and thermal control, 2) heat conductive pathways within the material for thermal equalization, 3) surface treatments for improved absorption or rejection of heat by the material, and 4) means for quickly regenerating the thermal storage capacity for reuse of the material. Applications of the composite materials are also described which take advantage of the composite's thermal characteristics. The examples described include a diver's wet suit, ski boot liners, thermal socks, gloves and a face mask for cold weather activities, and a metabolic heating or cooling blanket useful for treating hypothermia or fever patients in a medical setting and therapeutic heating or cooling orthopedic joint supports.

Technical method for building self-insulating and energy-saving wall with Z-shaped energy-saving building blocks

In the invention, the same clad bricks are laid in the forward direction, and a positioning convex platform 2 and a longitudinal positioning convex platform 3 are used for realizing transverse and longitudinal self-locking positioning, thereby naturally ensuring the designed thickness and surface smoothness of the wall, forming a combined still air layer 12 which is 9mm to 10mm wide and vertical to the ground, and further blocking heat bridges in vertical bricklaying seams. The cavity of a 28-30mm-wide groove 4 in the horizontal bricklaying seam between two clad bricks is filled with a broken bridge insulation board 10 which is as wide as the groove and has a thickness of 15mm; the broken bridge insulation board 10 is used for sealing a long-strip groove still air layer 11 and the combined still air layer 12 and cutting off the heat bridges in the horizontal bricklaying seams; the exposed part of broken bridge insulation board with a height of 10mm, is used for controlling the coating thickness of anti-crack masonry mortar 13 to be even and uniform. When the self-insulating and energy-saving wall is built, Z-shaped energy-saving building blocks 1 of the upper clad bricks and the lower bricks are laid in a staggered manner so as to cut off heat bridges in vertical bricklaying seams. The structure of the invention, with a reasonable thickness, can satisfy the requirement of saving 50 percent of energy in various regions, or even higher requiremets without an internal or external insulating layer of walls. Simultaneously, the structure is easy to build and the formation of the block shape effectively ensures the thickness of walls and the smoothness of wall surfaces. The thermal insulation function of the still air layer with a thickness of 10mm to 12mm strengthens the heat insulation effect. The insulation boards (28-30mm wide and 15mm thick) between the two clad bricks is capable of cutting off the heat bridge effects.

Built-up synergetic class-A/B water extinguishing agent series

The invention discloses a built-up synergetic class-A / B water extinguishing agent series. Class-A fires caused by solid substances (such as woods, cottons, wools, linens, paper) and products thereof and class-B fires caused by liquid or melted solids such as gasoline, kerosene, diesel oil, crude oil, methanol, ethanol, asphalt, paraffin waxes and the like can be put out rapidly through the functions such as heat absorption and cooling, diluting and smothering, insulating and covering, suppressing and blocking combustion chains, and the like which are synergetically performed by various extinguishing functional components, and a high-temperature-resistant thermal-insulation and fire-retarding covering layer is formed on the surface of an inflammable matter by various after-combustion functional components so as to achieve the effect of after-combustion resistance. Because the class A / B fires relate to multiple occasions of daily life and production activities, the extinguishing agent disclosed by the invention can be used in the fields of home fire prevention and extinguishing, urban architecture fire prevention and extinguishing, oil depot and gasoline station fire prevention and extinguishing, vehicle and ship fire prevention and extinguishing, forest and grassland fire prevention and extinguishing, mine fire prevention and extinguishing, confined spaces (such as civil air-defense architectures) fire prevention and extinguishing.

Carbon nanostructures and process for the production of carbon-based nanotubes, nanofibres and nanostructures

Continuous process for the production of carbon-based nanotubes, nanofibres and nanostructures, comprising the following steps: generating a plasma with electrical energy, introducing a carbon precursor and/or one or more catalysers and/or carrier plasma gas in a reaction zone of an airtight high temperature resistant vessel optionally having a thermal insulation lining, vaporizing the carbon precursor in the reaction zone at a very high temperature, preferably 4000° C. and higher, guiding the carrier plasma gas, the carbon precursor vaporized and the catalyser through a nozzle, whose diameter is narrowing in the direction of the plasma gas flow, guiding the carrier plasma gas, the carbon precursor vaporized and the catalyses into a quenching zone for nucleation, growing and quenching operating with flow conditions generated by aerodynamic and electromagnetic forces, so that no significant recirculation of feedstocks or products from the quenching zone into the reaction zone occurs, controlling the gas temperature in the quenching zone between about 4000° C. in the upper part of this zone and about 50° C. in the lower part of this zone and controlling the quenching velocity between 103 K/s and 106 K/s quenching and extracting carbon-based nanotubes, nanofibres and other nanostructures from the quenching zone, separating carbon-based nanotubes, nanofibres and nanostructures from other reaction products.

The invention relates to a high-temperature-resistant thermal insulation and heat preserving ceramic coating and a preparation method thereof. The coating is prepared from the following raw materials in percentage by weight: 30-50 percent of film forming substance, 30-40 percent of high-temperature-resistant filler, 10-15 percent of hollow micro beads, 2-5 percent of thermal insulation fiber and 2-8 percent of aid and solvent. The coating has the toughness of an organic coating and the rigidity and hardness of an inorganic coating, has high adhesion, can be used at the high temperature of 400-1,200 DEG C for a long time, and is resistant to chemical reagents, acids, alkalis and oil. A coating film has high surface intensity, and can bear strong shear force without being damaged when a high-temperature pipeline is required to be connected mechanically. The coating has excellent heat preserving performance, and the surface temperature of a pipeline of 350 DEG C can be lowered to be below 100 DEG C by coating the coating outside the pipeline in the thickness of 4-6 millimeters. The coating can be widely applied to heat-resistant protection of the inner and outer surfaces of equipment such as high-temperature steam pipelines, metallurgy high-temperature furnaces, high-temperature valves, high-temperature containers and the like.
