Title:
HEAT ACCUMULATING COMPOSITION, ITS PRODUCTION AND PRODUCTION OF HEAT ACCUMULATOR
Document Type and Number:
Japanese Patent JP2659350
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a heat accumulating composition in which each component in the heat accumulating composition is homogeneously mixed and capable of taking out a large latent heat and repeatedly using for a long period, provide a production of the same and of a heat accumulating device.
SOLUTION: This heat accumulating composition contains a supercooling- protecting agent such as sodium sulfate decahydrate, sodium borate 10 hydrate, etc., a silica-based thickener such as water glass, and barium sulfate. This production of the heat accumulating composition is to prepare a gel-like material having pH 7-8 by mixing water with water glass and hydrochloric acid and mix anhydrous sodium sulfate, the supercooling protecting agent and barium sulfate one by one in an arbitrary order with the obtained gel-like material.
