The chemical essence of 99.5% high-purity slaked lime is calcium hydroxide (Ca (OH) ₂), whose purity refers to the content of calcium hydroxide per unit mass being ≥ 99.5% (mass fraction). Compared with ordinary industrial grade slaked lime (with a purity of about 85% -92%), it removes impurities such as calcium carbonate (CaCO3), magnesium oxide (MgO), and iron/aluminum oxides through a multi-stage purification process, making the effective ingredients close to the theoretical value, presenting the characteristics of high activity, low impurities, and controllable performance.
Application Scenarios
Food & Pharmaceutical Industry:
As a food additive (e.g., flour improver, acidity regulator), compliant with GB 1892-2016 (ordinary slaked lime is banned due to heavy metals).
Pharmaceutical excipients (e.g., dental filling materials, antacid ingredients), leveraging high purity and biocompatibility.
Electronics & New Energy:
Calcium source in lithium battery cathode materials (e.g., lithium iron phosphate), controlling impurities to prevent battery short circuits.
pH regulator for semiconductor wafer cleaning solutions, requiring metal ion content <1ppm.
Environmental Protection & Advanced Water Treatment:
Deep treatment of heavy metal wastewater (e.g., Pb²+, Cd²+ removal rate ≥99.99%).
Alkalizing agent for ultrapure water systems, avoiding impurity ion contamination.
High-End Chemicals & Materials:
Catalyst support (e.g., biodiesel synthesis), using high specific surface area to enhance catalytic efficiency.
Filler for premium coatings, improving film gloss and weather resistance.
