Glauber Salt Which Replace Soda Ash In The Glass Industry

Glauber Salt , Sodium Sulfate , Hot-melt evaporation dehydration method

Heat the mirabilite prepared by the freezing method in a hot melt tank to around 70℃. Some of the sodium sulfate dissolves in its own crystalline water, forming a saturated solution.

Some sodium sulfate precipitates anhydrous salts. After centrifugal drying and separation, anhydrous sodium sulfate crystals and saturated solution are obtained. The crystal becomes the finished product after drying.

The saturated solution is further evaporated to obtain anhydrous mirabilite. After centrifugal dehydration and drying, the finished product is obtained. This process is repeated in this way.
