Description
Powdered Activated Carbon for Warmer Patch
The warmer patch material for warmer patch is include iron powder, activated carbon, vermiculite, water, salt and other materials. The heating principle is that iron powder naturally nourishes and releases heat. Under normal circumstances, the oxidation of iron powder is relatively slow, and heat cannot accumulate. Under the action of activated carbon powder, the contact area between iron powder and air increases, producing the heat we can feel. Salt and water are also used to accelerate the oxidation of iron powder. This principle was first seen in traditional Chinese medicine therapy bags, which use iron powder and vinegar for therapy.
The function of powdered activated carbon for warmer patch is to adsorb moisture from the air, ensuring a smooth oxidation process. It also has thermal conductivity, so it can dissipate heat evenly. After heating, the volume of charcoal expands, leaving millions of small holes between carbon atoms, which increases the surface area of each gram of carbon to two thousand square kilometers. The surface area of one pound of activated carbon is as large as leaving six football fields – these gaps are enough to absorb moisture.
Therefore, the main functions of activated carbon in the heating process of warm stickers are twofold:
- Adsorb water and oxygen from the air to facilitate oxidation;
- As a carrier of iron powder, it increases the contact area with air, resulting in more uniform and long-lasting heat generation.
