Magnesium Chloride Hexahydrate Flakes - High Purity Dust Suppressant, Eco

Product Specification

Product Title

Magnesium Chloride Hexahydrate Flakes - Dust Suppressant, Deicing Agent, Feed Supplement

English Description

Magnesium chloride, with the chemical formula MgCl₂, typically exists as the hexahydrate (MgCl₂·6H₂O) in the form of white or light yellow flakes, granules, or lump crystals. This product is a widely used basic magnesium salt and chemical raw material. Leveraging its unique properties—strong hygroscopicity, endothermic dissolution, role as a magnesium source, and the binding nature of its solution—it plays an indispensable role in numerous fields including environmental protection, road maintenance, agriculture, chemical industry, construction, and food.

In-Depth Analysis of Core Applications:

1. The Versatile Performer in Environmental Protection and Road Maintenance:

   • Efficient Dust Suppressant: Due to its strong hygroscopic and deliquescent properties, magnesium chloride solution is widely used for dust control on unpaved roads, mining sites, construction areas, and material stockpiles. Spraying forms a long-lasting moisture-retaining film on surfaces, effectively binding fine particles and preventing dust generation, all in an environmentally friendly manner.

   • Eco-friendly Deicing Agent: As an alternative to traditional sodium chloride (rock salt), magnesium chloride has a lower freezing point and is less corrosive, causing less damage to concrete and metals. Its endothermic dissolution rapidly melts ice and snow, maintaining high efficiency even at low temperatures. It is extensively used for winter maintenance on highways, airports, and urban roads.

   • Flocculant in Wastewater Treatment: In some industrial wastewater treatments, it can serve as an auxiliary flocculant or magnesium agent for phosphate removal and pH adjustment.

2. The Nutritional Source in Agriculture and Animal Husbandry:

   • Feed-Grade Magnesium Chloride: An important mineral additive in livestock and poultry feed, it supplements magnesium to prevent disorders like "grass tetany" (spasms, restlessness) caused by magnesium deficiency, which is particularly critical for ruminants.

   • Foliar Fertilizer and Soil Amendment: Can be used as a water-soluble magnesium fertilizer to correct magnesium deficiency symptoms (interveinal chlorosis) in crops, especially fruits and vegetables, providing rapid magnesium nutrition. It can also be used to amend acidic soils.

3. The Foundational Material in Chemical and Building Industries:

   • Production of Magnesia Cement (Sorel Cement): Mixed with magnesium oxide (MgO), it is the primary raw material for producing high-strength, highly fire-resistant, and wear-resistant magnesia cement, used in manufacturing fireproof boards, partition walls, and flooring.

   • Raw Material for Magnesium Metal Production: The electrolysis of molten anhydrous magnesium chloride is the primary industrial method for producing metallic magnesium.

   • Other Chemical Uses: Serves as a precursor for manufacturing magnesium compounds like magnesium hydroxide and magnesium carbonate; used as a sizing agent and filler in the textile industry; and as a secondary coolant in refrigeration.

4. The Quality Improver in Food and Pharmaceutical Industries:

   • Food-Grade Magnesium Chloride (E511): Functions as a coagulant, stabilizer, and flavor enhancer. It is a key coagulant (a major component of "bittern") in producing tofu and dried tofu products, imparting their characteristic flavor and texture. Also used for mineral fortification in mineral water and sports drinks.

   • Pharmaceutical-Grade Magnesium Chloride: Used in formulating dialysis solutions and as a raw material for electrolyte supplements.

This product is strictly categorized into Industrial Grade, Feed Grade, and Food Grade based on its intended use. Our supplied magnesium chloride boasts high purity (MgCl₂ content ≥46%), low impurity levels (e.g., sulfate, alkali metals), and fast dissolution speed. The flake/granule form offers good flowability, facilitating mechanical spreading or dissolution. We provide stable, high-quality magnesium chloride products to road maintenance companies, environmental contractors, feed mills, chemical plants, and food processing enterprises, along with application-specific usage guidance and technical support.
