Index Description: Industrial superior grade features higher purity, ultra-low impurities and excellent particle uniformity, suitable for high-precision production scenarios such as glass, fine chemical industry and high-end building materials. Industrial first grade delivers outstanding cost performance and meets the needs of conventional industrial mass production. Food grade strictly controls harmful impurities including heavy metals, arsenic and lead, complying with national mandatory standards for food additives. It can be legally used in various food processing scenarios with complete traceable qualifications.

4. Product Characteristics

Dense soda ash is composed of uniform and compact white granules with high bulk density and regular particle shape. It boasts excellent fluidity with zero dust during feeding and extremely low material loss. Featuring ultra-low hygroscopicity and superior anti-caking performance, it resists moisture deterioration even after long-term warehousing, stacking and long-distance transportation. With stable batch purity, uniform color difference and ultra-low impurities, it maintains stable chemical properties and adapts to continuous operation of automated production lines, serving as the preferred soda ash specification for industrial mass production and foreign trade export.

5. Main Applications

The product is divided into industrial grade (superior grade & first grade) and food grade for targeted application in different scenarios, with detailed classification as follows:

5.1 Applications of Industrial Grade Dense Soda Ash

Glass Manufacturing Industry (Core Application): As the core flux raw material for float glass, flat glass, daily-use glass, photovoltaic glass, optical glass and container glass, it effectively reduces the glass melting temperature, improves glass transparency, flatness and finished texture, lowers raw material loss in kilns, extends kiln service life, and acts as an essential raw material for the glass industry.

Building Materials & Ceramics Industry: Applied in the production of ceramic glaze, refractory materials, ceramic tile blanks and cement additives. It adjusts the pH value of raw materials, enhances the hardness, glossiness and forming stability of building material finished products, and optimizes product appearance and durability.

Metallurgical Desulfurization Industry: Used in the smelting process of steel, aluminum, copper, lead and other non-ferrous metals as a desulfurization, dephosphorization and impurity removal auxiliary. It eliminates impurities in metal raw materials, optimizes smelting quality, reduces exhaust pollution, and adapts to large-scale metallurgical production lines.

High-end Chemical Synthesis: Used for the production of high-end inorganic salt chemical products such as sodium silicate, phosphate and carbonate. With stable raw material purity and sufficient reaction without dust and impurity interference, it effectively improves the purity and qualification rate of chemical finished products.

Daily Chemical & Environmental Protection Industry: Applied in the formulation of high-end detergents and industrial cleaning agents, water softening, industrial and domestic sewage acid-base neutralization, flue gas desulfurization, and denitrification. It features no flying material and low loss, suitable for large-scale environmental protection treatment projects.

Other Industrial Scenarios: Widely used in leather processing, oilfield drilling auxiliaries, rubber accessories, and high-end papermaking pulping, adapting to various industrial production scenarios with high requirements for material stability and cleanliness.

5.2 Applications of Food Grade Dense Soda Ash

Pastry Processing: Used as edible alkali in the production of steamed buns, buns, noodles, cold noodles, pastries, and other pasta products. It neutralizes lactic acid generated by dough fermentation, removes sour taste, brightens pasta color, and makes pasta soft, chewy, and better in appearance.

Food pH Adjustment: Applied to pH value adjustment in the production of bean products, baked goods, rice and noodle products and condiments, stabilizing food flavor and optimizing food processing technology.

Food Cleaning Treatment: Used for soaking and cleaning fruits, vegetables, grain and oil ingredients to remove surface pesticide residues, oil stains and acidic impurities with no safety residue, adapting to standardized cleaning operations in food processing factories.

Food Additive Production: As a compliant food additive raw material, it is used in the formulation and production of food leavening agents, buffers and food improvers, legally applied in various food deep processing scenarios.

6. Packaging Specifications
