Sheet-shaped heating element

Abstract

Abstract PURPOSE:To improve the contact efficiency of a composition and an air and to prevent the calorific value from reducing by molding in a sheet shape the composition composed by mixing a fiber-shaped substance to at least an iron powder, an activated carbon, an electrolyte and water by paper-making. CONSTITUTION:A fiber-shaped substance is suspended in water, beated lightly with a refiner, etc., the iron powder, activated carbon, electrolyte, water-holding agent, additives, etc., are added to this, stirred, suspended, filtered through a paper making machine with a wire, and after dewatering by suction, they are sandwiched with a canvas, etc., further, the dewatering is executed with the press, molded to thickness of about 0.2-10mm and thus, the sheet-shaped heating element of the moisture content 5-65wt.% is obtained. Both surfaces of the sheet-shaped heating element 1 are covered with a permeability film 2, and a peripheral part 3 is bonded by adhesive or sealed by the thermal fusion. Since the heating element does not generate the bias due to the movement of a heating composition like the conventional one, a stable heating performance is obtained and at the time of installation in human body, the sense of incompatibility does not occur.
