What is the liquid in the hot water bag? There is no poison?
After the water can be used to charge the hot water bag, after the water to clean the air, rapid expansion when charging, if the quality is not good, prone to short circuit or even explosion. In the purchase of hot water bags, should pay more attention to product packaging, pay attention to whether the above marked product identification, underwriting units, national standards, product description and use of attention, etc.. Due to the sale of a lot of heating supplies on the market, product quality is uneven, so pay attention to the choice of regular brands in the purchase, do not covet cheap buy.But when using, do not think that electric hot water to a certain temperature power will automatically jump, part of the product quality, the temperature keeps rising until the explosion. Therefore, the charging time should not be too long, people do not leave the electric hot water bottle, touch electric hot water temperature, found sufficient heat, early power, this can avoid the occurrence of excessive temperature and pressure ".
This kind of hot water bag is sold in two states, one is the manufacturer has been filled into the conductive liquid, buy can be used directly. There is also a way to buy when there is no water, but has been put into a powder (iron or ferrite), you have to fill their own water, the effect is the same. So the liquid in the bag can not be replaced by tap water, otherwise it will not be hot.So the bag is not generally liquid water, which contains a conductive material, hot water bag is electromagnetic heat generated by the solenoid that is closed to prevent leakage, if the electricity will cause magnetic field and magnetic iron is the interaction of the so-called water surface eddy current and hysteresis and it produces heat, and the transformer why fever is relevant because of hysteresis and eddy current heat, the transformer made of a piece of silicon steel sheet is to reduce the hysteresis and eddy current, so as to improve the efficiency, and the hot water bag is opposite, so the electricity heating. If replaced by water, because water is a bad conductor, it will not heat, so the bag of liquid can not be replaced with water.
Liquid semiconductor, plug in hot water bag (also known as warm water treasure, electric heating bag, personal warming, etc.) with its affordable, long-term thermal insulation and selling.
