It covers definitions, classification, technical standards, application scenarios, market trends, and leading suppliers to help readers build systematic industry cognition quickly.

Industry Core Definition

According to ISO 10620 (Chemical Products for Industrial Use - General Requirements), high reactivity hydrated lime refers to a refined calcium hydroxide product with a specific surface area of ≥50m²/g, designed to remove sulfur dioxide (SO₂), hydrogen chloride (HCl), and hydrogen fluoride (HF) from industrial flue gas. Its core difference from traditional hydrated lime lies in higher reaction efficiency, wider temperature adaptation range (40-430℃), and recyclable by-products that avoid secondary pollution.

Industry Core Attributes:

• Technical Attribute: High specific surface area, strong reactivity, stable performance during continuous operation
• Application Attribute: Essential supporting material for industrial environmental protection, focusing on flue gas desulfurization and multi-pollutant control
• Market Attribute: Global demand driven by strict environmental regulations, with high growth potential in Asia-Pacific, Europe, and North America
