About the principle of insole heating, can heating insole burn

The self-heating insoles are held together with a breathable adhesive. Among them, the self-heating cloth uses the self-heating mineral tourmaline to generate heat, and the massage magnetic plates are distributed in several major acupuncture points such as Yongquan acupoint.

Rechargeable and reusable heating insole, automatic gear to maintain the temperature at 45, manual high-end maximum temperature up to 45, manual mid-range maximum temperature up to 41, manual low-range maximum temperature up to 36 degrees. The charging time is about one hour, the insole can be used for 6-8 hours in automatic transmission, the insole can be used for 6-8 hours in manual high-end, the insole can be used for 8-10 hours in manual mid-range work, and the insole can be used for 10-12 hours in manual low-range use.

Q=i RT can also be equivalent to UIT, and those who have studied junior high school know that most of them now say what their products are and what fibers are instead of heating wires, because the heating wire is prone to high temperature, which eventually leads to scalding or potential safety hazards. But those what what fibers, the calorific value is small, the heating is slow, the efficiency is low, I have bought a similar heating sheet for DIY before, but now it is still piled up there useless, the reason is that the calorific value is too low, and the voltage and current are not necessarily much higher, not to mention that you are talking about the insoles, the insoles generally have their own power supply to facilitate the convenience of going out, but the general battery voltage is low and the capacity is small, if the cost of lithium battery is too high, it will lead to an illusion" A pair of insoles is so expensive" will directly affect its sales, so it is generally not used. To sum up, with the current technology, the heating element has not yet been used to achieve the expected effect that people want.

It cannot be burned from the insole to be worn, put in the shoe and not taken out, it will not catch fire, the heat generated is not very high, far below the ignition point, and will not catch fire.

Disposable heating insoles are mainly a chemical, which becomes hot when exposed to oxygen, as if it is iron oxide, and a layer of cloth contains something like a stone, except for easy scalding, there is no other danger, it is recommended to put the disposable heating insole under the insole, otherwise it is very hot feet, I have used it.

At present, there are two kinds of heating insoles on the market, one is aerogel type, and the other is self-heating wormwood insole, which should not be too harmful to the human body at present.

Let's start with the aerogel heating insole, which is a minimum thermal conductive solid, and the thermal insulation is better than that of traditional materials, and the clothes used by astronauts also have this composition, and this kind of insole can keep heat very well.

There is another kind called self-heating wormwood insole, the composition is iron powder, vermiculite and activated carbon, vermiculite can expand at high temperature, belongs to a kind of silicate, can be used as a thermal insulation material, can also be insulated, fireproof, moisture-proof, activated carbon in the case of air isolation, can also play a heating role, iron powder can also increase the temperature, at present these ingredients are not too harmful to the human body, of course, it depends on the effect after use.

Self-heating. Heating principle of insoles:

Self-heating insoles are a high-tech product made by using breathable adhesives to fix the layers of far-infrared anion layer, heating cloth layer, sweat-absorbing cotton cloth, heat insulation layer and massage magnetic sheet together; Among them, the self-heating cloth uses the self-heating mineral tourmaline.

Heat is generated, and the massage magnetic plates are distributed at several major acupuncture points such as Yongquan acupoint.

The (self-)heating insoles really get hot. Details are as follows:

When the fibers in the insole fabric absorb moisture in the air, the hydrophilic groups in the fiber molecules and the water molecules are combined, thereby reducing the kinetic energy of the water molecules into heat energy, thereby transmitting heat to the human body.

The heating performance of the self-heating insole has a great relationship with the moisture regain rate of the fibers in the insole, and the moisture regain rate of the fibers is good, and the heating performance is poor. The moisture absorption and moisture regain of wool is larger, so the heating performance of wool is good, while the moisture absorption and moisture regain of polyester is small, so the heating effect of polyester is worse than that of wool.

(Self) heating insoles have strong applicability and are widely used

The heating insole can be trimmed according to the user's yardage, no need to worry about the problem of inappropriate yardage, and the heating insole is light and thin, suitable for any shoes, boots, such as work boots, hunting boots, ski boots, ski boots, sports shoes, casual shoes, single shoes, etc.

Heating insoles are heated at constant temperature and kept warm, and are widely used by people, such as outdoor sports people, outdoor work people, people who often have cold hands and feet, middle-aged and elderly people, and people who sit in the office for a long time.

The above content reference: Encyclopedia - self-heating insole.

FeverThe insole will not**. The self-heating insole is worn and put in the shoe without taking it out, and it will not **. The heat generated is not very high, well below the ignition point, and does not catch fire.

The disposable heat-generating insole is mainly a chemical that becomes hot when exposed to oxygen, as if it were iron oxide.

A layer of cloth contains something like a stone, except that it is easy to burn.

There are no other dangers.

Advantages and principles of self-heating insoles

Strong warming function. Since the self-heating insoles have the effect of self-heating, they can reach a higher temperature in an instant, which is warm and comfortable to wear, and gives good protection to the feet. Breathable and sweat-wicking. Since there is sweat-absorbing cotton cloth in the self-heating insole, it has good breathability for sweaty feet.

is the best insole.

Anti-mildew, deodorant, antibacterial. Due to the special material of the self-heating insole, bacteria cannot breed in it, which plays a good role in sterilization and keeps it in a dry environment. Heating insoles are a high-tech product made of breathable adhesives to fix the layers of far-infrared anion layer, heating cloth layer, sweat-absorbing cotton cloth, heat insulation layer and massage magnetic sheet together.

The heating insoles are made of self-heating mineral tourmaline.

Heat is generated, and the massage magnetic plates are distributed at several major acupuncture points such as Yongquan acupoint. Among them, self-heating uses the self-heating mineral tourmaline to generate heat, and the massage magnetic plates are distributed in several major acupuncture points such as Yongquan acupoint.
