Problems solved by technology

[0003] One method is that the hydrogen generated by the reaction with oxygen is catalyzed to eliminate the hydrogen generated by the reaction of magnesium water, for example, the reaction of hydrogen and oxygen is catalyzed by palladium to generate water, and the hydrogen generated by the reaction is eliminated, but due to the speed at which oxygen dissolves in water Very slow, the amount of oxygen and hydrogen dissolved in 10min is very small, not enough to completely remove hydrogen, so the method of eliminating hydrogen by reaction after hydrogen generation is actually difficult to achieve

Abstract

The invention discloses an application of a hydrogen inhibitor in a self-heating food heating agent. The hydrogen inhibitor is anhydrous cupric chloride or copper chloride; the self-heating food heating agent is a magnesium-iron series heating agent; the hydrogen inhibitor is 0.2-2 times the total weight of the heating agent. The hydrogen inhibitor is capable of inhibiting release of hydrogen, and more in heat release and higher in reaction speed as compared with the traditional magnesium-iron series heating agent; if no power supply and no heat source are provided, the self-heating food heating agent with the hydrogen inhibitor can be used for heating various kinds of food without releasing hydrogen, and is applicable to airtight spaces.

Description

technical field [0001] The invention belongs to the field of chemical heating materials, and in particular relates to the application of a hydrogen suppressor in a self-heating food heating agent. Background technique [0002] Self-heating food heating agent is a new type of heating agent that uses metal, non-metal or chemical materials as raw materials to generate heat through physical or chemical principles, and can heat food or water through simple activation. It is widely used in military instant heating Food heating, mountaineering tourism and emergency support for emergencies, my country began the development of self-heating food heating agents in the 1980s, and has gone through three stages: quicklime, aluminum water reaction system, magnesium water reaction system, quicklime The heating agent has been eliminated due to uncontrolled heat release and low calorific value. The aluminum water reaction system is a type of heat agent widely used in the market in our country....
