Can you salt the water from a PVC hot water bottle?


PVC hot water bottles can be salted. PVC hot water bag has a disadvantage, is cool fast, what method to delay the hot water bag cool? In fact, the use of hot water bags, just add a certain amount of salt in hot water, can improve the heat preservation effect of hot water bags and time, to remind that the greater the concentration of salt water, the better the heat preservation effect, but the solubility of salt water, add excess is not necessary. Each time you use the hot water bag, you only need to heat the salt water and reuse it to achieve the insulation effect.


PVC hot water bottles can be kept warm longer with salt. Cold air arrives and the hot water bottles come in handy. A few days ago, affected by cold air from the south, the city staged a "cooling show", idle for a long time of the water hot water bag "appearance" to shoulder the responsibility of warming feet and bedding. Can fill water hot water bag to have a drawback, COOL QUICKLY namely, HAVE what METHOD TO delay hot water bag to cool, add brine to go. Two identical hot water bottles filled with hot water, one with a 1:3 ratio of salt to the water. After 25 minutes, the water in the hot water bag was measured with a thermometer. The temperature of the hot water bag without salt was 31.4℃, and the temperature of the hot water bag with salt was 34.6℃. Compared with the same type of hot water bag, the hot water bag with salt can keep warm longer than the one without salt.


Why does salt in  PVC hot water bottles keep you warm

When salt is added to boiled water, the density of water will increase. The specific heat capacity of salt water is larger than that of water, and the temperature reduction rate of salt water is slower than that of water. Therefore, the actual effect and time of heat insulation of warm handbags with salt are stronger. But it has to be mentioned that salt water has solubility, the greater the concentration of salt water, the better the actual effect of heat insulation, heat insulation effect will not be significant only add a small amount of salt in boiling water. And every time the boiling water put salt is really consumed, so after the warm bag turns cold, only need to warm the salt water, repeated use, but also can achieve the actual effect of heat insulation.
