What is a salt pad?

This heater is a closed,hermetic container, made of dense material. The container is filled with supersaturated saline solution. Inside, you can see a small applicator, which, in fact, is the trigger mechanism.

Salt Warmer: the principle of action

In fact, the mechanism of operation is quite simple. As already mentioned, the inside contains a supersaturated solution of salt. And the applicator, floating in it, is called the "trigger of reaction". When the applicator breaks, the equilibrium of the solution changes rapidly. The liquid begins to crystallize around the broken bacillus. This process is accompanied by the release of heat - this is how the catalytic reaction takes place.

After using the heating pad it needs to be restored- for this purpose it is put in hot water. Crystallized substance actively absorbs heat - so the salt solution returns to the state of primary equilibrium.
