Food Industry Used in baked goods such as bread and biscuits, it can control the fermentation rate and improve production efficiency.
Quality Improver: When used in biscuits and pastries, it can extend the shelf life, reduce the breakage rate, and make the products porous and uniformly textured.Moisture Retainer: In meat product processing, when used in combination with other phosphates, it can enhance the water retention of the products.Chelating Agent: In aquatic product processing, it can prevent the formation of crystals and control moisture.
Emulsifier: In dairy products, mayonnaise, and other foods, it can reduce the surface tension between oil and water phases, promoting their mixing to form a stable emulsion.
Chemical Production:Dispersant and Emulsifier: Helps other substances to disperse and mix better.
Water Softener: In water treatment, it can form soluble complexes with calcium and magnesium ions in hard water, thus softening the water quality.
Scale Remover: In boiler descaling, it can dissolve carbonate and other mineral deposits, effectively removing the scale inside the boiler.
Textile and Electroplating Industry:Textile Auxiliary: During dyeing and finishing, it helps dyes penetrate fibers better, improving the dyeing effect.
Electroplating Solution Formulation: In the electroplating industry, it can form complexes with iron, playing a key role in the electroplating process.
Toothpaste Additive: It can form a gel with calcium hydrogen phosphate and stabilize it, enhancing the cleaning effect of toothpaste.
Detergent Ingredient: Used in the production of synthetic detergents and shampoos, it has good dirt removal and dispersion properties.
Papermaking Industry:Bleaching Agent: Used for bleaching paper and plant fibers, it can improve the whiteness and quality of paper.
Petroleum Drilling:Water Treatment Agent: In the petroleum drilling industry, it plays a certain role, especially as a water treatment agent.
Feed Industry:Feed Additive: Used in pet cans, animal feed, aquaculture feed, vitamin feed, etc.
Pharmaceutical Field:Drug Stabilizer: Acts as a stabilizer and formulation component for some drugs.
Mechanical Processing
Rust Remover: Effectively removes rust from metal surfaces, providing a clean surface for subsequent processing and treatment.
7.Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
