99% Purity Magnesium Chloride Hexahydrate MgCl₂·6H₂O for Deicing Agent and Dust Control

English Description

Magnesium chloride, with the chemical formula MgCl₂·6H₂O (hexahydrate), is a significant inorganic magnesium salt and multifunctional chemical. This product appears as colorless to white crystalline solid (flakes, granules, or powder), with a bitter taste. It possesses properties including strong hygroscopicity, high solubility, freezing point depression, and serves as an excellent magnesium source. Leveraging its unique physicochemical characteristics, magnesium chloride plays a crucial role in diverse fields such as environmentally friendly deicing, road dust control, animal feed nutrition, construction materials/chemicals, and food processing, making it an economical and functional basic industrial raw material.

In-Depth Analysis of Core Applications:

1. The Winter Guardian in Environmental Deicing and Road Maintenance:

   • High-Efficiency Eco-friendly Deicing Agent: Compared to traditional sodium chloride (rock salt), magnesium chloride offers advantages such as a lower freezing point (-33°C), significantly reduced corrosivity, and weaker damaging effects on concrete and metals. Its dissolution absorbs substantial heat, rapidly breaking down ice and snow structures, and it maintains high activity in low-temperature environments. Widely used for winter deicing operations on highways, airport runways, urban streets, and sidewalks.

   • Long-lasting Dust Suppressant: Utilizing its strong hygroscopicity, magnesium chloride solution sprayed onto unpaved construction roads, mining areas, stockpiles, and transport routes forms a moisture-retaining layer on soil particles and promotes crust formation, effectively suppressing dust with lasting results and environmental friendliness.

2. The Essential Element Supplement in Agriculture and Animal Husbandry:

   • Feed-grade Mineral Additive: Serves as an essential magnesium supplement in animal feed, preventing and treating "grass tetany" in ruminants (e.g., cattle, sheep) caused by magnesium deficiency, maintaining normal neuromuscular function, and improving feed conversion efficiency. Suitable for dairy/beef cattle, sheep, and specialty animal feeds.

   • Foliar Fertilizer and Soil Amendment: Formulated as a water-soluble magnesium fertilizer to correct magnesium deficiency symptoms (interveinal chlorosis) in crops (e.g., fruit trees, vegetables), quickly restoring photosynthetic capacity; also used to amend acidic soils.

3. The Fundamental Raw Material and Functional Aid in Chemical and Construction Industries:

   • Core Component of Magnesia Cement (Sorel Cement): Reacts with magnesium oxide (MgO) to form high-strength, highly fire-resistant, and wear-resistant magnesium oxychloride cement (Sorel cement), used in producing fireproof boards, ventilation ducts, partition walls, packaging cases, and municipal manhole covers.

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

   • Other Chemical Uses: Used in manufacturing magnesium hydroxide flame retardants, magnesium carbonate, and other magnesium compounds; used in the textile industry as a sizing agent and fabric flame-retardant treatment agent; serves as a secondary coolant in refrigeration brines.

4. The Safe Processing Auxiliary in Food and Pharmaceutical Industries:

   • Food Additive (E511): Food-grade magnesium chloride is primarily used as a coagulant, being the key ingredient in producing bittern tofu and dried tofu, imparting their characteristic flavor and texture. Also used as a mineral fortifier, pH regulator, and processing aid.

   • Pharmaceutical Raw Material: Used in formulating hemodialysis solutions, electrolyte supplements, and as a magnesium source for certain medications.

Product Grading and Key Parameters:
This product is strictly categorized based on intended use into Industrial Grade (for deicing/dust control), Feed Grade, Food Grade (E511), and Pharmaceutical Grade. Core quality indicators include magnesium chloride content (typically ≥46%), control of impurities (sulfates, alkali metals, heavy metals), dissolution rate, and particle morphology.

Usage and Storage Precautions:
The product is highly hygroscopic and requires sealed, moisture-proof storage. When used as a deicing agent, application rate per unit area should be controlled to avoid overuse affecting vegetation. Food-grade applications must strictly comply with relevant usage limit standards.
