Winter PVC hot water bottle warm effect is not very good, add a little salt to try it.

The use of hot water bottle, just add a certain amount of salt in the hot water, you can improve the thermal insulation effect and time of the hot water bag, it should be reminded that the greater the concentration of salt water, the better the thermal insulation effect, but the solubility of salt water, it is not necessary to add excessive. Each time you use the hot water bag, you only need to heat the salt water and reuse it to achieve the thermal insulation effect.

The principle is that after adding salt to hot water, the density of water will rise, the specific heat capacity of salt water is larger than that of water, and the cooling rate of salt water is slower than that of water. Therefore, the heat preservation effect and time of the hot water bag with salt are better. However, it must be mentioned that salt water has solubility, the greater the concentration of salt, the better the thermal insulation effect, the hot water with only a small amount of salt insulation effect will not be obvious. And every time the hot water is also a waste of salt, so after the PVC hot water bottle becomes cold, you only need to heat the salt water and reuse it, and you can also achieve the insulation effect.
