WhatsappSodium Hydroxide Pellets Manufacturing process
Step 1: Raw Material Selection
- High-purity sodium chloride (NaCl) undergoes quality checks.
Step 2: Electrolysis Process
- Sodium hydroxide is produced by the electrolysis of brine solution.
- The process yields high-purity NaOH, hydrogen gas, and chlorine gas.
Step 3: Concentration & Pellet Formation
- The NaOH solution is concentrated to form solid pellets.
- The pellets are shaped for uniformity and easy handling.
Step 4: Quality Control & Testing
- The product undergoes rigorous testing for purity, solubility, moisture content, and pH per IP/BP/USP standards.
Step 5: Packaging & Storage
- Packed in HDPE containers to prevent contamination and moisture absorption.
- Stored in a dry, cool environment to maintain stability.
