Why does warm baby have fever? What is the principle of warming baby?
What makes warm baby warm is the raw materials inside, such as activated carbon, iron powder, water, inorganic salts and so on. When you tear that layer of gelatin, the polymer reacts with the oxygen in the air, which produces a heating reaction.
Activated carbon has the effect of heat conduction, the oxidation process of activated carbon can be successfully completed because activated carbon can absorb water in the air. When heated, the charcoal will expand, and holes will appear between the carbon atoms. The surface area of each pound of activated carbon can be increased to the same size as six football fields, so these gaps can completely absorb water.
Iron powder will react with oxygen in the air to form iron oxide, which will release heat when the iron is corroded. The heat released will make the temperature of iron powder rise, generally to about 68 ℃.
Many cities with more snowfall will use sodium chloride for deicing, and the cars we park outside are often corroded by sodium chloride. In the warm baby principle here, sodium chloride can make iron powder corrode.
Vermiculite is hydrated, so it expands when heated, and it looks like a worm crawling. Vermiculite's water absorption capacity is very strong, and itself is also very light, also does not have the chemical reaction, this is one kind can fire prevention very good material.

Because although the temperature of warm baby and warm water bag is not high, it will form heat accumulation after contacting with skin for a long time. The skin will be damaged gradually from the superficial dermis to the deep dermis and subcutaneous tissues. There will be erythema, blisters and other symptoms on the surface.
