| 摘要 |
A powder thermal storage composition activated by exposure to microwave energy including a combination of a powder, a phase-change material, and a microwave-sensitive material combined to provide an impregnated powder (43) that has at least more than 50 n % to substantially all of the individual powder particles impregnated with both the phase-change material and the microwave-sensitive material; the impregnated powder (43) may be produced by the process of: (I) mixing an emulsion with a powder; (II) mixing a powder first with either microwave-sensitive material or phase-change material and then mixing the resultant powder with the phase-change material or the microwave-sensitive material, respectively; or (III) vigorously mixing the powder while spraying microwave-sensitive material and phase-change material (either separately or as a mixture) into the vigorously mixing powder; the thermal storage mixture (43) may be used in a container, to provide a thermal construction comprising a seat cushion (3) having a thermal storage unit (20) therein.
