Method for making a quasi-incompressible phase-change material with low thermal conductivity, and resulting product

摘要: The invention concerns a method for making quasi-incompressible phase-change material (PCM) having low thermal conductivity, the resulting products and their uses. consists in combining with liquid state thickening agent selected to reduce significantly convection, formed having, depending on combinations performed, gelled structure or colloidal dispersed system. PCM of mixture chemical compounds family alkanes, paraffins, waxes, fatty alcohols, acids like, can be organic (aromatic ureas), organometallic (alkaline alkaline-earth soaps) purely inorganic (silica, silico-aluminates such as bentonite made oleophilic). is useful isolation containers ducts, particular insulation hydrocarbon ducts.
