Applications

Ajustement du pH
Élimination du tartre
Adjuvant de désinfection
Neutralisation des effluents alcalins

Recommandations de dosage

For pH control: meter to target pH. For descaling: 5-15% solutions. For neutralization: stoichiometric calculation based on alkalinity.

Mode d'action

Strong monoprotic acid that rapidly lowers pH, dissolves calcium and magnesium carbonate/hydroxide deposits, and enhances chlorine disinfection effectiveness.

Conseils d'utilisation

Corrosive — use acid-resistant equipment. Fuming acid — ensure adequate ventilation. Compatible with most water treatment systems for pH reduction.

What materials are compatible with hydrochloric acid storage?▼
HCl should be stored in polyethylene (PE/HDPE), polypropylene (PP), or rubber-lined steel tanks. Avoid stainless steel, aluminum, and carbon steel which corrode rapidly. FRP (fiberglass reinforced plastic) tanks are also suitable for concentrations up to 37%.
What is the difference between technical grade and reagent grade HCl?▼
Technical grade HCl (30-37%) is used for industrial applications like pH adjustment, scale removal, and metal pickling. Reagent grade (≥37%, high purity) is used in laboratories and pharmaceutical applications with stricter impurity limits on iron, sulfate, and heavy metals.
How should hydrochloric acid spills be handled?▼
Contain the spill with inert absorbent material (vermiculite, dry sand). Neutralize with soda ash (Na₂CO₃) or lime (Ca(OH)₂). Wear full PPE including acid-resistant gloves, splash goggles, and respiratory protection. Refer to the Safety Data Sheet for detailed emergency procedures.
