Advantages and Disadvantages of Magnesium Chloride and Calcium Magnesium Acetate as Deicing Agents

1. Magnesium Chloride Deicing Agent

Magnesium chloride deicing agent belongs to the chloride salt deicing agent category, which also includes sodium chloride, calcium chloride and other similar products. Such deicing agents are generally processed by mixing different raw materials in a certain proportion.

For example, a common formula is 40% magnesium chloride, 10% sodium chloride, 30% calcium chloride, 10% calcium magnesium acetate and 10% corrosion inhibitor. Custom proportioning is also available according to customers’ requirements.

2. Advantages and Disadvantages of Magnesium Chloride Deicing Agent

Advantages

1. High cost performance:Among all types of deicing agents, magnesium chloride-based deicing agents are relatively low in price, generally ranging from several hundred to more than one thousand RMB per ton.

2. Excellent snow melting and anti-freezing performance:Magnesium chloride has a low freezing point, remaining unfrozen at -10℃ to -20℃. It can work normally in low-temperature environments and is more resistant to severe cold than single sodium salt deicers.

3. Fast snow melting speed:Magnesium chloride features strong moisture absorption. Its efficient snow-melting effect can be clearly observed during application.

4. Easy to use:It can be manually spread, sprayed directly by sprinkler trucks, or dissolved in water and applied with greening sprinkler vehicles.

Disadvantages:

1. Excessive application will cause corrosion to cement ground, vehicle chassis, steel bars, guardrails and bridge metal components. Long-term and overuse will lead to rusting and aging of metal facilities.

2. Excessive infiltration into soil will cause soil salinization and affect the growth of roadside green plants and lawns. However, when used in a reasonable dosage, it can supplement magnesium and calcium elements for vegetation and promote healthier growth. As a matter of fact, magnesium chloride is also widely used as fertilizer for crops.

3. Calcium Magnesium Acetate (CMA) as Deicing Agent

Calcium Magnesium Acetate, abbreviated as CMA, is a chlorine-free environmentally friendly organic deicing agent. It is widely used in airports, precision instrument factories and developed regions with strict environmental protection requirements.

Calcium Magnesium Acetate (CMA) Advantages

1. Non-corrosiveAs an eco-friendly deicer, its corrosion degree to metals such as steel and guardrails is close to that of tap water. It causes almost no damage to concrete and asphalt roads, making it ideal for newly built pavements, steel structure bridges and airport facilities.

2. Eco-friendly and harmlessIt contains no chloride ions, nitrogen or phosphorus, and is fully biodegradable. Its degradation products are calcium and magnesium ions, causing no soil salinization or groundwater pollution. It is non-toxic to plants, pets and aquatic organisms.

3. Good low-temperature resistanceIt has a low freezing point and long-lasting mild effect. One-time spreading achieves long-term ice inhibition and reduces repeated application. It performs stably at low temperatures of -20℃ to -35℃ without losing efficacy easily.

4. No risk of overuseSince calcium magnesium acetate is non-corrosive, over-application will not cause any harm.

Calcium Magnesium Acetate (CMA) Disadvantages：

High cost: The price of calcium magnesium acetate is about 10 to 20 times that of magnesium chloride deicing agent.

To sum up, both magnesium chloride and calcium magnesium acetate have their own pros and cons. The final choice mainly depends on customers’ actual demands.
