Product Introduction
Sulfuric Acid for Industrial Use (H₂SO₄), industrial grade concentration 98%±0.5%, density approximately 1.84 g/cm³ (20℃), strong acidity, strong dehydration, and strong oxidizing properties; used for acidification reactions, pH adjustment, dehydration and drying, and sulfate production.
pH Range
Strong Acid Environment (pH 0–2): Rapidly lowers pH, suitable for acid washing and strong acid reaction systems.
Neutral Adjustment (pH 3–7): Precisely controls acidity, improving reaction stability.
Alkaline Neutralization (pH > 7): Efficiently neutralizes alkaline solutions, producing stable sulfates.
Coagulation Effect
Promotes Metal Salt Hydrolysis
Optimizes Al³⁺/Fe³⁺ reaction conditions, improving coagulation efficiency.
Accelerates Flocculation and Sedimentation
Shortenes sedimentation time, improving treatment efficiency.
Reduces Overall Chemical Consumption
Precise pH control reduces coagulant dosage.

Batch Stability
① Raw Material Control: High-purity sulfur or SO₂ from smelting tail gas is used as raw material to control impurity content at the source.
② Active Ingredient Detection: Each batch is tested for H₂SO₄ content, Fe, As, Pb, and other impurity indicators to ensure compliance with industrial standards.
③ Performance Consistency Testing: Reaction performance is ensured through density, concentration, and acidity titration verification.
④ Batch Deviation Control: A batch traceability system is established, with concentration deviation controlled within ±0.5%.
