Product Application

Detergent Industry (Traditional Major Use):

Filler & Processing Aid: A key component in synthetic detergents (laundry powder) as a filler, anti-caking agent, and processing aid​ to improve powder flowability and bulk density.

Glass Industry:

Finishing/Refining Agent: Used as a refining agent​ in glass melting. Decomposes at high temperatures, releasing gases that help remove fine bubbles from the melt. Also provides a sodium source.

Pulp & Paper Industry:

Kraft Pulping Process: An important chemical for replenishing sulfur and sodium​ in the chemical recovery cycle of the sulfate (kraft) pulping process.

Textile Dyeing Industry:

Leveling & Exhausting Agent: A critical auxiliary in the dyeing process, especially for direct, sulfur, and vat dyes, improving dye utilization and levelness.

Chemical Synthesis:

Raw Material: Used in manufacturing sodium sulfide, sodium silicate, ultramarine, and other sodium-based chemicals.

Pharmaceuticals & Food (Requires High-Purity Grades):

Pharmaceutical Excipient: Used as a diluent and filler.

Food Additive: Used as a processing aid and anti-caking agent (limited use).

Other Applications:

Sodium silicate (water glass) production, animal feed supplement, cement accelerator, heat storage medium in cooling systems.
