Description
Product Uses:
- Gypsum Board Production: Enhances the strength and toughness of gypsum boards and improves water resistance.
- Raw Material for Producing Vc Phosphate Ester:
Combines the benefits of Vitamin C.
Overcomes the tendency of Vitamin C to oxidize when exposed to light, heat, and metal ions.
- Preparation of Cross-linked Starch:
Used as an esterification and cross-linking agent in industrial processes.
Features efficient, environmentally friendly, high conversion rates, and low cost, suitable for various product processing needs, and provides excellent product performance.
- Food Industry:
Acts as a stabilizer and dispersant in ice cream and dairy products.
Effectively prevents cloudiness in fruit juices and tea beverages and prevents food discoloration.
- Inorganic Surfactant::Due to its unique molecular structure, it serves as an excellent inorganic surfactant.
- Water Softener:
Strong chelating ability.
Forms soluble complexes with calcium, magnesium, and iron ions dissolved in water, keeping them inert and turning the water into soft water.
- Dispersant:
Strong gelation capacity.
Disperses many insoluble compounds and suspensions (including pigments).
Prevents dirt from depositing on textile fibers.
Helps form stable latex-like solutions, promotes particle dispersion, and maintains stability.
- Detergent Additive:
Accelerates particle dispersion and enhances cleaning efficiency when used with other detergents.
Maintains the pH of detergent solutions within the optimal range.
When used for washing light metals, it prevents damage from alkalis.
- Buffer in Hydrogen Peroxide Bleaching.
- Raw Material for Producing Premium Toothpaste:
Acts as an abrasive.
Prevents and removes cavities.
Most effective phosphate in dental health among all phosphates.
Packaging, Storage, and Transportation:
- Available in 25kg, 50kg, 1000kg, 1200kg, 1250kg bags with customizable options.
- Store in a dry, well-ventilated area, and avoid exposure to moisture. It retains its quality during long-term storage, and any clumping can be resolved by crushing or dissolving before use.
- Non-toxic and non-hazardous, it can be transported by road, sea, or rail as general cargo.
