Soda Ash (Sodium Carbonate) Light & Dense Grade is an indispensable basic industrial alkali raw material with huge global consumption volume, and Linkwin implements separate crystallization and densification production lines for light and dense soda ash to avoid mixing, ensuring stable total alkali content, low iron and insoluble impurities, preventing glass yellowing, detergent discoloration and reaction incomplete defects in downstream application. Light soda ash has loose particle structure, fast dissolution rate and strong reaction activity, preferred for neutralization, precipitation and fine chemical synthesis scenarios; dense soda ash has compact particles, high stacking density, low dust generation, less moisture absorption caking tendency, specially customized for large-scale glass furnace continuous automatic batching system to reduce dust loss and workshop environmental pollution. High iron impurity is the most common quality defect of inferior soda ash, directly causing glass greenish discoloration and poor whiteness of detergent products.

In glass industry, soda ash acts as main fluxing agent to lower silica melting temperature, reducing energy consumption for float glass, bottle glass, architectural hollow glass and fiberglass production, occupying more than half of total soda ash consumption market. Detergent & soap field: soda ash is key alkaline builder to enhance detergency, soften hard water and saponify grease for laundry powder, liquid detergent and soap manufacturing. Papermaking industry uses soda ash as cooking alkali for pulp delignification and pH adjustment for paper making white water circulation system. Environmental protection sector applies soda ash to neutralize acidic wastewater, precipitate heavy metal ions and adjust alkalinity for flue gas desulfurization system. Many overseas glass and detergent manufacturers frequently face high iron content, unstable total alkali and easy caking problems from low-grade soda ash suppliers; our strict recrystallization purification and grading packaging completely eliminate these production troubles, stabilizing finished product whiteness and formulation consistency.
