(57) [Summary] [Purpose] A coolant that produces endothermic heat when mixed with chemicals. It has excellent cooling performance, and even if the bag is torn, the chemical does not scatter, and there is little ammonia odor. Get a safer coolant. [Structure] A polymeric flocculant is added to a cooling agent in which an inorganic ammonium salt such as ammonium nitrate and a salt having water of crystallization such as strontium hydroxide octahydrate are combined. A liquid such as water generated by the cooling reaction is gelled. |
