Abstract: The present invention discloses a multi-screen supporting device in a high-temperature adiabatic calorimeter, and belongs to a calorimeter device in calorimetry. The multi-screen supporting device comprises a vacuum tank, three layers of protecting screens, two layers of thermal insulation screens, a protecting screen supporter for supporting and fixing the protecting screens, a thermal insulation screen supporter for supporting and fixing the thermal insulation screens, and a connecting piece for connecting and fixing the protecting screen supporter and the thermal insulation screen supporter. The multi-screen supporting mode in the high-temperature calorimeter solves the problems of time consumption for disassembling and assembling, low multi-screen assembling coaxiality and reduced experimental repeatability caused by many parts moved in each disassembling and assembling in the existing high-temperature calorimeter. The multi-screen supporting mode is easy in part processing, high in disassembling and assembling efficiency and convenient in operation, and effectively improves the experimental repeatability.

Abstract: The present invention discloses a hydrate energy-storage temperature-control material and a preparation method therefor. The material includes a refrigerant hydrate and a cross-linked polymer. The preparation method comprises the following steps: first, preparing a refrigerant hydrate by using a high-pressure reactor, and conducting grinding, crushing and sieving to obtain hydrate particles; then, uniformly spraying polytetrafluoroethylene suspended ultrafine powder onto the surface of the hydrate particles by using an electrostatic spraying device, and putting the hydrate particles into a plasma instrument to modify polytetrafluoroethylene so as to allow free radicals to be formed on the polytetrafluoroethylene powder surface; finally, subjecting monomers to graft polymerization with the free radicals on the polytetrafluoroethylene surface under the irradiation of a high-pressure mercury lamp of UV lighting system to stabilize the structure of the material, preparing a final product. According to the present invention, a hydrate energy-storage temperature-control material with good stability is prepared. A method capable of preparing various types of refrigerant hydrate materials is provided. The product can give full play to the advantages of hydrate energy storage and temperature control, can be periodically used, and can be used in various fields such as building, refrigeration, etc.
