PURPOSE:A device using heat effective for preventing corrosion of copper, obtained by blending a heat accumulative material consisting essentially of sodium acetate trihydrate and a heating medium consisting essentially of a Flon material with a specific anti-corrosive agent. CONSTITUTION:The desired device using heat obtained by blending (A) a heat accumulative material of a system consisting essentially of sodium acetate trihydrate with (B) a heating medium of a system consisting essentially of a Flon and (C) cetyl mercaptan and/or dodecyl mercaptan as an anti-corrosive agent. Preferably 0.001-10wt% component C is directly added to the component B, or the component C in an amount to give the above-mentioned range based on the component B used, is premixed with the component A. |
