Hydrated Lime

Description

1. Product Overview

Hydrated Lime (Calcium Hydroxide, Ca(OH)₂) is a high-purity, dry alkaline powder produced through the controlled slaking of quicklime. Its primary industrial use spans environmental remediation (flue gas treatment, water softening), construction (mortars, stabilized base layers), and chemical processing (pH regulation). The key value proposition is its exceptional reactivity and cost-efficiency as a neutralizing agent, delivering consistent performance across critical industrial workflows. Strategically, it is indispensable for heavy industries facing tightening emission regulations and water quality mandates—making supply reliability a board-level operational priority.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Calcium Hydroxide, Ca(OH)₂ ≥ 92% (typical); residual MgO ≤ 2%; SiO₂, Al₂O₃, Fe₂O₃ as trace

• Purity Level: Industrial grade (92–96%) / Premium grade (≥97%) available upon request

• Physical Characteristics:

  • Fine white powder

  • Particle size: 200 mesh (≤ 75 µm) minimum 95% passing

  • Bulk density: 400–600 kg/m³ (loose)

  • Specific surface area: ≥ 15 m²/g (high reactivity)

• Packaging Options:

  • 25 kg HDPE laminated woven bags

  • 1,000 – 1,500 kg jumbo FIBC bags

  • Pneumatic tanker truck / bulk pressure differential delivery

• Shelf Life: 12 months when stored in dry, covered, low-CO₂ conditions (prevents carbonation)

3. Core Industrial Applications

• Flue Gas Treatment (Dry Scrubbing / Spray Dryer Absorbers):
  Removes SO₂, HCl, SO₃ from power plants, cement kilns, and incinerators. Performs better than sodium bicarbonate in cost-per-mole of acid gas neutralization, especially in high-temperature ducts.

• Water & Wastewater Treatment:
  pH adjustment, heavy metal precipitation, and temporary hardness reduction. Outperforms caustic soda in cost stability and safety handling—no exothermic runaway risk.

• Soil Stabilization for Infrastructure:
  Reacts with clay minerals to reduce plasticity and swell potential. Provides superior long-term durability compared to Portland cement alone in subgrade and capping layers.

• Chemical & Metallurgical Processing:
  Calcium salt production, sugar refining (carbonatation), and lubricant manufacturing (calcium sulfonate complex). Delivers consistent alkalinity without introducing soluble carbonates that interfere with downstream processes.

4. Competitive Advantages

• Quality Consistency: ISO 9001:2025 certified production with real-time particle size analysis and purity testing per ASTM C207 / EN 459-2; batch-to-batch COA provided.
