Description

Technical Field

[0001] The utility model relates to the technical field of sodium sulphate processing, in particular to a double-stage pushing centrifuge. Background Art

[0002] Sodium sulfate is a salt formed by the combination of sulfate and sodium ions, with the chemical formula Na2SO4. Sodium sulfate is soluble in water, and its solution is mostly neutral. It is soluble in glycerol but insoluble in ethanol. Inorganic compounds, high-purity, fine-grained anhydrous substances are called glauber salt. Glauber salt is white, odorless, bitter crystals or powder, and is hygroscopic. The appearance is colorless, transparent, large crystals or granular small crystals. Sodium sulfate easily absorbs water when exposed to air, forming sodium sulfate decahydrate, also known as Glauber's salt, which is alkaline. It is mainly used in the manufacture of water glass, glass, porcelain enamel, pulp, refrigeration mixtures, detergents, desiccants, dye diluents, analytical chemical reagents, pharmaceuticals, feed, etc.
