Applications
Glass Manufacturing: Used as a fluxing agent to lower the melting point of silica sand for float glass, container glass, and photovoltaic glass
Detergents & Soaps: Serves as an alkali source and builder for laundry powder and industrial cleaners
Water Treatment: Adjusts pH and removes temporary hardness for drinking water softening and industrial cooling water systems
Chemical Manufacturing: Raw material for sodium silicate, sodium bicarbonate, sodium phosphates, and other chemicals
Textile Industry: Acts as a pH buffer in dyeing processes and fiber treatment
Pulp & Paper: Used in pulping and pH adjustment
Household Cleaning & Pool Maintenance: For hard water softening and pH balance adjustment
Our Advantages
Defined Purity Specifications: Total alkalinity ≥99.2% with impurity limits below standard industrial grade maximums. Batch-to-batch total alkalinity variation controlled within ±0.2%
Multiple Grade Options: Light grade (bulk density 0.5–0.6 g/ml) suitable for pneumatic conveying and batch reactions. Dense grade (bulk density ≥0.65 g/ml, granular) suitable for continuous feeding and glass furnaces with controlled carryover loss
Predictable Dissolution Performance: Under stirring at 20°C, complete dissolution time is 2–4 minutes for light grade and 4–6 minutes for dense grade
Storage and Transport Stability: Supplied with moisture-proof inner lining. When stored at relative humidity ≤60%, caking remains controlled within 6 months with no increase in water insoluble matter
International Standards Compliance: Specifications meet general industrial grade sodium carbonate standards for glass, detergent, water treatment, and other industries
