What's in the thermos?
Liquid semiconductor, plug-in hot water bottle (also known as warm water treasure, electric warm bag, personal warm, etc. ) is popular because of its affordable price and long heat preservation time.
This hot water bottle can be sold in two states. One is that the manufacturer has filled the conductive liquid and can use it directly after buying it. Another kind of powder (iron powder or ferrite) is bought without water, and the effect is the same if you want to fill it yourself. So the liquid in the bag can't be replaced by tap water casually, otherwise it won't be hot.
So the liquid in the bag is not ordinary water, but contains conductive substances. The hot water bottle is sealed with electromagnetic heat energy to prevent leakage. If it is electrified, it will produce a magnetic field, and iron and magnetism will interact, so that the so-called eddy current and hysteresis will occur in water, which is related to why the transformer heats up because of hysteresis and eddy current. People make transformers into pieces of silicon rigid sheets to reduce hysteresis and eddy current, thus improving efficiency. If you change to water, because water is a poor conductor and will not generate heat, the liquid in the bag cannot be changed to water.
Rechargeable hot water bottle can only be used after it is filled with water. The air should be purified after being filled with water, and it will expand rapidly when charging. If the quality is not good, it is easy to short circuit or even explode. When buying rechargeable hot water bottles, pay more attention to the product packaging, and pay attention to whether the product identification, underwriting unit, national standard, product description and precautions are marked on it. Because there are many heating products sold in the market, the quality of the products is uneven, so we should pay attention to choosing regular brands when buying, and don't buy "three no products" on a cheap basis.
And when using, don't think that the electric hot water bottle will automatically jump off when it reaches a certain temperature. Some products are not up to standard, and the temperature will keep rising until it causes an explosion. Therefore, "the charging time should not be too long, people should not leave the electric hot water bottle, touch the temperature of the electric hot water bottle with their hands, and turn off the power supply as soon as possible if it is hot enough to avoid excessive temperature and pressure."
What's in the electric hot water bottle?
It is a conductive substance, which is generated by heat energy generated by electromagnetism. Everything electromagnetic is sealed to prevent leakage. If electricity is applied, a magnetic field will be generated. Iron and magnetism will react with each other, creating eddy currents and hysteresis in so-called water, and then generating heat energy. The liquid in the electric hot water bottle is not ordinary water, but contains conductive substances. Hot water bottles are generated by heat energy generated by electromagnetism. Electromagnetic things are closed to prevent leakage. If electricity is applied, a magnetic field will be generated. Iron and magnetism interact to produce eddy currents and hysteresis in so-called water, and then heat energy will be generated.
What water is in the hot water bottle used in winter? What color is the water?
When I first bought it, it was the color of clear water, but it turned brown after a long time.
What water is in the electric hot water bottle?
The electric hot water bag is filled with iron oxide and water.
Salt water can also be used instead, but there is a buzz when electric heating is plugged in.
I don't know whether salt water will affect the life of electric hot water bottles for the time being.
Pay attention to the proportion of salt water. If the concentration is too high, the power is too great, and the power is too great. Think for yourself.
What should I put in the hot water bottle to get hot?
It is hot only when it is filled with boiling water.
What liquid is in the thermos? Why is there gas? It's always drum. That sounds horrific.
That's because the air generated by steam will be discharged normally for a long time after each heating.
What are the advantages of putting salt water in a hot water bottle?
Liquid brine is an electrolyte solution, which heats up much faster than water and keeps the temperature longer!
What water is in the hot lunch bag?
It may be water that has not been carefully disinfected and sterilized, or it may be recycled water, which generally does not kill people and has diarrhea at most.
What water is in the rechargeable warm water bag?
The solubility of solute in solvent is constant, for example, the solubility of salt (sodium chloride) in water is 36g/ 100mL water at room temperature. When the concentration in a solution is equal to its solubility, this solution is called a saturated solution; When the solubility of a solution is higher than its solubility, it is called supersaturated solution. The liquid in the warm handbag is a supersaturated solution of sodium acetate.
What can replace the water in the hot water bottle?
The liquid in the bag is not ordinary water, but contains conductive substances. One is that the manufacturer fills the conductive liquid and can use it directly after buying it back. Another kind of powder (iron powder or ferrite) is bought without water, and the effect is the same if you want to fill it yourself. So the liquid in the bag can't be replaced by tap water casually, otherwise it won't be hot.
