What is self-heating material? Self-heating material recommendation

In our daily life, we often use heating materials. Think of some self-heating bento boxes, which use self-heating materials to heat the bento boxes. And some consumers will also use self-heating health care products for health care. Today, let's learn what self-heating materials are and the recommendation of self-heating materials.

What is self-heating material

Good disposable self-heating material is the material that physical therapy and health care personnel have been trying to find. There are many open patents in China that use iron powder to generate heat, using iron powder, water, activated carbon, inorganic salts and other materials. The disadvantage of these methods is that water will evaporate rapidly in the actual use process, thus reducing or losing the heating ability. The author uses room temperature ionic liquid [Bmim][BF4] (chemical name is 1- methyl -3- butyl imidazole tetrafluoroborate) instead of water and inorganic salts to prepare a disposable spontaneous heating material that can be used for physical therapy and health care. The use of new materials overcomes the above shortcomings and makes the self-heating materials release heat stably.

self-heating materials are recommended

1. Metal magnesium

Metal magnesium does not need any energy, and it can generate a lot of heat when combined with air. However, the fever is rapid, and it is difficult to control the heating speed under normal circumstances.

2. Electrolyte material

Polymer gel solid electrolyte (SPE) was prepared with acrylamide sodium bromide and PEG6. The SPE was mixed with reduced iron powder and activated carbon to prepare a self-heating material, which was solid, released heat when exposed to air, and was dormant when not exposed to air. It can be used as a heating mounting material for rubber plaster or black plaster, and a human body hot compress material.

3. Physical therapy material editing

Methods: PolymerinSalt electrolyte (SPE) was prepared with urea, thiourea and polyethylene glycol (PEG), and the SPE was mixed with reduced iron powder and activated carbon to prepare self-heating material.

Results: Self-heating materials were solid, and released heat when they were in contact with air, but they were dormant when they were not in contact with air. The controlled release of heat could be achieved by controlling the contact amount with air, and the heat release effect was good.

Self-heating materials are widely used in outings, tours and outdoor activities, and can be used as a heat source to heat food, and the health care products made are also beneficial to human body. The above is what Xiaobian introduced to you about what self-heating materials are and what self-heating materials recommend. I hope it will help you to know self-heating materials!
