Magnesium Chloride Storage — De-Icer Brine Tank System Selection
Storing Magnesium Chloride? Start Here
Magnesium chloride is a versatile chemical used for de-icing roads, dust suppression, and in various industrial brine applications. It's favored for its ability to melt ice at lower temperatures and its reduced corrosiveness compared to traditional rock salt. Whether you're managing winter road safety or controlling dust on unpaved roads, understanding how to store magnesium chloride effectively is crucial.
Can you store it in a poly tank?
Yes, you can store magnesium chloride in a polyethylene (poly) tank. Both HDLPE and XLPE tanks are suitable for storing up to 30% concentration of magnesium chloride. Ensure that the tank is equipped with PVC or PP fittings and EPDM gaskets for optimal performance.
Key Issue: Hygroscopic Nature
Magnesium chloride is hygroscopic, meaning it absorbs moisture from the air. While this property is beneficial for dust suppression, it can pose challenges in solid form storage. For liquid storage, this isn't a concern, but if you're handling solid magnesium chloride, ensure airtight containers and rapid transfer to prevent it from turning into a liquid.
The safety that actually matters
- Use corrosion-resistant materials for tanks and fittings to prevent chloride-induced damage.
- Store tanks outdoors without heating, as magnesium chloride brine remains pumpable in extreme cold.
- Ensure proper handling and personal protective equipment to avoid skin and eye irritation.
Common questions
- Can magnesium chloride be used in extremely cold temperatures?
- Yes, it remains effective in temperatures as low as -15°F, making it suitable for most winter conditions.
- Is magnesium chloride less corrosive than rock salt?
- Yes, it is less corrosive to vehicles and infrastructure compared to sodium chloride (rock salt).
- What are the storage requirements for magnesium chloride?
- Store in polyethylene tanks with PVC or PP fittings and EPDM gaskets. Outdoor storage is generally acceptable.
