Expanded Information
Thermal salt is also known as sea salt , drying salt, generally consists of seawater or salted material, usually after a series of processes such as evaporation of seawater, filtering, and drying. Hot pack salt is commonly used to make hot pack salt packs and physical therapy supplies.
Crude salt is dissolved in water to remove insoluble impurities, and then refined agents such as NaOH, Na2CO3 and CaCl2 are added to make SO42-, Ca2+, Mg2+, Fe3+ and other soluble impurities into precipitates, which are filtered and removed, and then finally, the PH is adjusted to 7 with pure hydrochloric acid, and the concentrated solution is obtained from the pure sodium chloride crystals.
