Magnesium Hydroxide, a versatile and environmentally friendly chemical compound, is gaining traction across various industries for its unique properties and applications. As a leading manufacturer with years of expertise, Shandong Taixing Advanced Material Co., Ltd. is here to provide you with a comprehensive guide to this remarkable product. Whether you're in wastewater treatment, flame retardancy, or pharmaceuticals, understanding Magnesium Hydroxide's parameters and benefits is crucial for optimizing your processes.
Understanding Magnesium Hydroxide: A Multi-Purpose Solution
Magnesium Hydroxide [Mg(OH)₂] is a white, odorless solid that occurs naturally as the mineral brucite. It is poorly soluble in water but can act as an effective alkali source. Its non-toxic and eco-friendly profile makes it a preferred choice over many traditional chemicals. Industries value it for its:
Acid Neutralization: Excellent for pH control in wastewater and flue gas desulfurization.
Flame Retardancy: Decomposes endothermically, releasing water vapor that dilutes flammable gases and cools the substrate.
Nutritional and Pharmaceutical Use: Used as an antacid and laxative, and as a magnesium source in supplements.
Key Product Parameters: Why Quality Matters
Not all Magnesium Hydroxide is created equal. The efficacy of the product heavily depends on its specific parameters. At Shandong Taixing Advanced Material Co., Ltd., we ensure our products meet the highest standards of purity and consistency.
Detailed Parameter List:
Purity: High purity levels are critical for effectiveness and reducing unwanted side reactions.
Particle Size: Affects reactivity, suspension stability, and incorporation into final products.
Bulk Density: Influences handling, storage, and transportation costs.
Specific Surface Area: A higher surface area generally increases reactivity.
Whiteness: Important for applications in plastics and paints where color is a factor.
Loss on Ignition (LOI): Indicates the water content and stability of the product.
Technical Data Table:
| Parameter | Specification | Typical Value | Importance |
|---|---|---|---|
| Mg(OH)₂ Purity | ≥ 95% | 97.5% | Ensures high reactivity and effectiveness; reduces inert material. |
| Particle Size (D50) | Customizable | 1.5 - 3.0 µm | Finer particles offer better dispersion and reaction speed. |
| Bulk Density | Loose | 0.25 - 0.35 g/cm³ | Impacts packaging and flow characteristics. |
| Specific Surface Area (BET) | > 15 m²/g | 18-22 m²/g | Higher area promotes faster acid neutralization. |
| Whiteness | > 95 | 97 | Crucial for aesthetic applications in polymers and coatings. |
| Loss on Ignition (LOI) | 30 - 32% | 31.5% | Confirms chemical composition and thermal stability. |
This table underscores the precision behind a high-quality Magnesium Hydroxide product. When you source from Shandong Taixing Advanced Material Co., Ltd., you are not just buying a chemical; you are investing in reliability and performance.
Applications Spotlight: Where Does Magnesium Hydroxide Shine?
Environmental Protection:
Wastewater Treatment: A safe and effective alkaline agent for neutralizing acidic wastewater and precipitating heavy metals.
Flue Gas Desulfurization (FGD): Removes sulfur dioxide (SO₂) from industrial exhaust gases, helping plants meet environmental regulations.
Flame Retardant:
Wire & Cable: Used in polymer compounds for cables, it provides excellent flame retardancy without emitting toxic smoke.
Thermoplastics & Rubber: Acts as a halogen-free flame retardant filler in polyolefins, PVC, and synthetic rubbers.
Other Industries:
Pharmaceuticals: The active ingredient in many antacids to relieve heartburn and indigestion.
Agriculture: Used as a pH adjuster in soil and as a magnesium nutrient source in fertilizers.
Food Industry: Serves as a drying agent, color retention agent, and alkalinity regulator.
Magnesium Hydroxide FAQ: Your Questions, Answered
We understand you may have specific questions. Here are some of the most frequently asked ones.
Q: How does Magnesium Hydroxide compare to Calcium Hydroxide (Lime) in wastewater treatment?
A: Magnesium Hydroxide offers several distinct advantages over Calcium Hydroxide (lime). It is a milder alkali, which prevents over-neutralization and the formation of low-pH plumes. Its solubility is lower, leading to a more controlled and slower reaction, which is safer and easier to manage. Furthermore, the resulting sludge from Magnesium Hydroxide is often more dense and stable, reducing disposal volumes and costs. It is also less scaling and corrosive to equipment, minimizing maintenance downtime.
Q: Is Magnesium Hydroxide a safe flame retardant to use?
A: Absolutely. Magnesium Hydroxide is considered one of the safest and most environmentally benign flame retardants available. Unlike halogen-based retardants, it does not produce toxic or corrosive smoke when it decomposes. Its mechanism of action is physical: it cools the material by absorbing heat (endothermic decomposition) and releases water vapor to dilute flammable gases. This makes it ideal for applications where human safety is paramount, such as in public transportation, construction materials, and wiring.
Q: Can the particle size of Magnesium Hydroxide be customized for specific applications?
A: Yes, and this is a key service offered by advanced manufacturers like Shandong Taixing Advanced Material Co., Ltd. Particle size is a critical factor. For flame retardant applications in plastics, a finer, surface-modified particle is often required for better dispersion and mechanical property retention in the polymer matrix. For acid neutralization, a specific particle size distribution can be engineered to control the reaction rate. We work closely with our clients to tailor the particle size to their exact process and performance needs.
