HEAT-STORING MATERIAL

PURPOSE: A heat-storing agent of latent heat utilization type that is prepared by combining sodium acetate trihydrate with sodium sulfite as a supercooling preventive, thus showing stabilized thermal radiation without supercooling. CONSTITUTION: The objective heat-storing agent is prepared by adding sodium sulfite, as a supercooling preventive, to sodium acetate trihydrate, or a composition containing more than 40wt% of the same, preferably in an amount of 0.01W 30pts.wt. per 100pts.wt. of sodium acetate trihydrate. The sodium sulfite is preferably heptahydrate. EFFECT: The breakage of supercooling is ensured at a temperature over about 52W53°C and stabilized thermal radiation is effected at about 58°C.COPYRIGHT: (C)1986,JPO&Japio
