Product Description
Colloquially known as "white small salt," this substance mainly refers to white granular raw salt produced via solar evaporation methods. Defined by its fine, uniform crystalline particles and bright white color, it is derived from seawater or salt-lake brine that undergoes natural evaporation driven by sunlight and wind. Unlike refined salts, it undergoes minimal processing, thus preserving natural mineral components such as calcium, magnesium, sulfates, and trace elements. With a sodium chloride (NaCl) content ranging from 85% to 95%, it contains higher impurities than refined salts, granting it unique physical and chemical characteristics suitable for specific industrial and agricultural applications.pH CharacteristicsWith a pH value between 7 and 8, the salt exhibits neutral to alkaline properties, mainly attributed to the hydrolysis of magnesium salts. This feature provides a gentle buffering capacity, which offers advantages in water treatment processes.The salt has a pH of 7 to 8, showing neutral to alkaline characteristics. This is mainly because magnesium salts hydrolyze, providing a mild buffering ability that benefits water treatment processes.The manufacturing of Xiaobai salt relies essentially on solar evaporation, a traditional method where brine is channeled into shallow basins or ponds. As sunlight heats the water, evaporation occurs, gradually concentrating the salt until crystals form. This natural approach obviates the need for energy-consuming refining steps like filtration or chemical purification, thus maintaining:Mineral ImpuritiesCompounds such as magnesium chloride (MgCl2), calcium sulfate (CaSO4), and potassium salts remain intact, giving some batches a subtle grayish or yellowish hue. These impurities arise directly from the unrefined evaporation process.Granular StructureThe crystals generally have a diameter of 0.5-2 mm, characterized by a porous surface texture. This morphology improves solubility and osmotic efficiency, making it especially ideal for uses like pickling.

Application
Commonly called "white small salt," this substance mainly refers to white granular crude salt made by solar evaporation. Featuring fine, uniform crystalline particles and a bright white color, it comes from seawater or salt-lake brine that evaporates naturally under sunlight and wind. Unlike refined salts, it goes through little processing, so it keeps natural minerals like calcium, magnesium, sulfates, and trace elements. With 85% to 95% sodium chloride (NaCl), it has more impurities than refined salts, giving it unique physical and chemical traits for specific industrial and agricultural uses.
pH Properties
The salt has a pH of 7 to 8, showing neutral to alkaline characteristics. This is mainly because magnesium salts hydrolyze, providing a mild buffering ability that benefits water treatment processes.
Application in Coagulation Sedimentation
As an auxiliary agent for coagulation sedimentation, it enhances the aggregation of suspended solids via electrolyte action. For instance, in printing and dyeing wastewater treatment, the recommended dosage is approximately 50-100 mg/L.
Seawater Desalination Pretreatment
In the reverse osmosis seawater desalination process, raw salt can serve as a pH adjuster or antiscalant during the pretreatment phase. While this approach has a higher cost, it offers the advantage of local availability in certain coastal regions.
Packaging & Shipping
