उत्पाद वर्णन
Sodium Sulfate Anhydrous 99%
A versatile industrial chemical serving as detergent builder, glass making agent, and dyeing auxiliary with high purity and reliable performance.
Product Overview
Sodium sulfate (chemical formula Na₂SO₄) is available in anhydrous form (thenardite/salt cake) and as decahydrate (Glauber's salt). This product is a white crystalline powder or granules, odorless with a salty and bitter taste. As a fundamental inorganic salt, it serves as a crucial filler, auxiliary agent, diluent, and chemical reaction raw material across multiple industries.
Core Applications
Detergent Industry Filler and Builder
Sodium sulfate is a major component in synthetic laundry powder, functioning as an inert filler to adjust product density, improve flowability, and reduce costs. It lowers the critical micelle concentration of surfactants, enhancing cleaning performance while preventing powder caking.
Glass Manufacturing Fining Agent
In glass production, sodium sulfate acts as a "defoamer" and fining agent. When added to glass batches, it decomposes at high temperatures to release gases that help eliminate bubbles, improving glass homogeneity and transparency. Typically used with carbon to control decomposition temperature.
Textile Dyeing Leveling Agent
Used as an exhausting or retarding agent in dyeing processes with direct, sulfur, and vat dyes. Increases electrolyte concentration in dye baths to reduce charge repulsion between fibers and dye molecules, promoting uniform dye uptake and level coloring.
Multi-Purpose Industrial Applications
Papermaking: Replenishes sodium and sulfur in kraft pulping processes
Chemical Synthesis: Raw material for sodium sulfide, sodium silicate, ultramarine pigment, and other sulfur-containing chemicals
Refrigeration: Historical use in low-temperature baths due to freezing point depression
Construction: Cement accelerator for early hardening
Animal Feed: Controlled source of sodium and sulfur nutrients
Product Specifications
This product is primarily anhydrous sodium sulfate (thenardite/salt cake), graded into Industrial Grade I and Grade II based on purity, whiteness, and impurity content (calcium, magnesium, chloride). Sodium sulfate decahydrate (Glauber's salt) is also available for chemical raw material or medicinal applications.
Application Guidelines
While sodium sulfate has stable chemical properties and is safe for use, optimal performance requires proper application: avoid excessive use in detergents that may affect cleaning power; precisely control carbon ratios in glass manufacturing; and select appropriate dosages based on specific dyeing processes and requirements.
