Core Uses and Functions
1. Industrial Sector
Electroplating and Metal Treatment
Corrosion inhibitor: Inhibit metal oxidation in acid gold plating and silver plating solution to improve coating uniformity (such as PCB circuit board gold plating process)
Brightener: Combines with silver ions to form a complex to enhance the gloss of the coating (a key additive in the jewelry processing industry)
Textile Printing and Dyeing
Antioxidants: Prevent dye oxidation and fading, improve the color fastness of cotton and silk fabrics (0.5-2%)
Flame retardant treatment: Combined with phosphate, used for flame retardant modification of polyester fiber
2. Agricultural Applications
Fungicides and Plant Regulators
Inhibition of fungal spore germination (e.g. control of rice blast), bactericidal by interfering with bacterial sulfur metabolism
Promote the breaking of dormancy of tuber crops (potatoes, sweet potatoes) and increase germination rate (0.1% solution soaking treatment)
Sulfur sources in radiopharmaceutical labeling (e.g. ⁹⁹mTc labeled developer)
Biochemical Research
Protein denaturant (concentration 2-4M for urea-thiourea double denaturation electrophoresis)
DNA/RNA stabilizers (prevent nuclease degradation, for cryogenic sample preservation)
4. Environmental Protection and New Energy
Heavy Metal Wastewater Treatment
Formation of complex precipitate with cadmium (Cd²+) and lead (Pb²+) (removal rate > 95% at pH 6-8)
Battery Material
Lithium sulfur battery electrolyte additive, inhibition of polysulfide shuttle effect (2025 Ningde era patent technology)
Used as an interface passivator in perovskite solar cells, increasing the photoelectric conversion efficiency to 26.8%
