example 1
[0444]A heat generating composition having a water mobility value of 10, which is a mixture consisting of 100 parts by weight of a reduced iron powder (particle size: not more than 300 μm)), 7.0 parts by weight of active carbon (particle size: not more than 300 μm), 5.0 parts by weight of a wood meal (particle size: not more than 300 μm), 0.8 parts by weight of a water absorptive polymer (particle size: not more than 300 μm), 0.2 parts by weight of calcium hydroxide, 0.7 parts by weight of sodium sulfite and 11% of salt water, was used.
[0445]Next, as shown in FIG. 1, FIG. 2(a) and FIG. 3, by using the heat generating composition, heat generating composition molded bodies 2B were provided on the surface of a polyethylene film 5B of a substrate 5 made of the polyethylene film 5B provided with a 30 μm-thick acrylic adhesive layer 7 provided with a separator 10 by force-through molding using a trimming die having eight cavities of 5 mm in width×80 mm in length at intervals of 5 mm, so a...
example 2
[0452]A batchwise stirring tank composed of a mixer equipped with a rotary blade in a blade form of a ventilation fan was used as an oxidizing gas contact treatment device, and air was used as an oxidizing gas. First of all, a reaction mixture consisting of 100 parts by weight of a reduced iron powder (particle size: not more than 300 μm) and 5 parts by weight of 11% salt water and having a water mobility value of not more than 0.01 was charged in the contact treatment device vessel. Next, the upper portion of the contact treatment device vessel was opened to air, and the reaction mixture was subjected to self heat generation with stirring in the opened state to air under circumstances at 20° C. After about 20 seconds, at a point of time when the temperature rise of the reaction mixture reached 15° C., the reaction mixture was sealed in an air-impermeable accommodating bag and cooled to room temperature, thereby obtaining a heat generating mixture. The heat generating mixture had a ...
example 3
[0458]By using the same heat generating composition, substrate and covering material as in Example 1, except for changing the reduced iron powder of Example 1 to an iron powder (particle size: not more than 300 μm) containing 2% by weight of a carbon component resulting from a coating treatment of sponge iron with active carbon, heat generating composition molded bodies were molded by force-through molding using a trimming die having twelve cavities of 5 mm in width×80 mm in length at intervals of 7 mm, laminated on the substrate and covered by the covering material; the peripheries of the heat generating composition molded bodies 2B were sealed in a seal width of 5 mm to form a sectioned part 3; the periphery of a heat cloth 1 was sealed in a seal width of 8 mm; and a perforation 4 which can be cut by hand was provided in the sectioned part 3, thereby obtaining a heat cloth 1 provided with the perforation 4 of 153 mm in length×98 mm in width having twelve rectangular sectional exot...
