摘要： PURPOSE:To ensure a quick, simple and assured detection for the leakage of the regenerating material, by using a color developing material which is composed mainly of one of the water-soluble coablt salt, chromium salt, nickel slat, iron salt, vanadium salt, copper salt and manganese salt respectively. CONSTITUTION:A color developing material is composed essentially of one amoung the water-soluble cobalt dalt, chromium salt, nickel salt, iron salt, vanadium slat, copper salt and manganese salt of + bivalent or + trivalent ion. This color developing material develops a color to an aqueous electrolyte solution. For instance, an aqueous CoCl2 or Co(NO3)2 solution, i.e., water-soluble cobalt is absorbed into a carrier. And the pink color of the dry carrier changes into blue for a mixed heat accumulating material of CoCl2.6H2, i.e., the aqueous electrolyte solution and then into blue and purplish red for hypo (Na2S2O2. 5H2O) and NaCH3COO.3H2O for a high temperature material for heating respectively and furthermore into a purple color for a heat accumlating material composed of Na2HPO4.12H2O.
