What You Need to Know About Caustic Soda Flake? Common Buying & Technical FAQs
Q1: What is Caustic Soda Flake?
Q2: What are the main industrial applications of Caustic Soda Flake?
‑ Water treatment: Adjust PH value, neutralize acid wastewater, precipitate heavy‑metal ions.
‑ Pulp & paper: Digest wood fiber and remove lignin for pulp making.
‑ Textile industry: Mercerization, scouring and bleaching for cotton fabrics.
‑ Soap & detergent: Raw material for saponification reaction and industrial cleaner production.
‑ Fine chemical manufacturing: Produce sodium silicate, sodium aluminate and other chemical intermediates.
‑ Petroleum refining: Remove acidic and sulfur‑containing impurities from crude oil.
Q3: What purity grades are available for industrial‑use caustic soda flake?
- 99% Caustic Soda Flake: High‑purity grade, suitable for fine chemical synthesis, high‑standard water treatment and intermediate production.
- 98%‑99% Caustic Soda Flake: General industrial grade, cost‑effective for wastewater treatment, textile scouring and pulp processing.
Q4: What is the difference between caustic soda flake and caustic soda pearl?
‑ Caustic soda flake: Flaky solid, fast dissolving speed, ideal for large‑volume industrial mixing.
‑ Caustic soda pearl: Small bead‑shaped, less dust during handling, better for manual small‑batch feeding.
Q5: How should I store caustic soda flake properly?
‑ Keep packages tightly sealed, store in cool, dry and well‑ventilated warehouse.
‑ Isolate from moisture, acid chemicals and organics.
‑ Avoid long‑term exposure to air, otherwise it will absorb moisture and carbon dioxide and lose performance.
Q6: What safety precautions must be followed during operation?
‑ Avoid skin, eye and respiratory contact.
‑ Once contacting skin or eyes, rinse with plenty of running water immediately and get medical treatment.
‑ Do NOT use industrial caustic soda flake for household cleaning.
Q7: How to select the right caustic soda flake for my factory?
‑ Wastewater treatment, textile scouring, ordinary paper‑making: choose 98%‑99% industrial grade for better cost performance.
‑ Fine chemical synthesis, high‑purity intermediate production: select 99% high‑purity caustic soda flake.
Always confirm impurity index before bulk order.
