Product features
Anhydrous sodium pyrophosphate is a white crystalline powder that easily absorbs moisture and deliquesces in the air; sodium pyrophosphate decahydrate is a colorless monoclinic crystal or white crystal or crystalline powder that easily absorbs water in dry air. weathering. It loses crystal water when heated to 100°C. Easily soluble in water, the aqueous solution is alkaline, insoluble in alcohol. The aqueous solution is stable below 70°C and is hydrolyzed into disodium hydrogen phosphate when boiled. It has strong pH buffering properties and has a certain chelating effect on metal ions.
The aqueous solution is alkaline and will be hydrolyzed into disodium hydrogen phosphate when boiled. It weathers in dry air and easily absorbs moisture in the air and becomes deliquescent. It can undergo complex reaction with metal ions; when it meets Ag+, it generates white silver pyrophosphate.
It has the general properties of ordinary polymeric phosphates, that is, it has emulsification and dispersion properties, prevents fat oxidation, improves protein binding properties, and also has the function of inhibiting the oxidation and fermentation of food under high pH values.
Product Usage
1 In the food industry, it is used as a quality improver, emulsifier, buffer, chelating agent, etc. It acts to chelate metal ions in canned foods and can improve the quality of finished products. Melting agent and emulsifier for cheese. Used in soy sauce and bean paste to prevent browning of bean paste and improve the color.
2 It is used in the electroplating industry to prepare electroplating solutions and can form complexes with iron.
3 In the wool spinning industry, it is used as wool degreasing agent and bleaching agent.
4 It is used in the paper industry for bleaching paper and plant fibers.
5 In the printing and dyeing industry, it is used as an additive in printing, dyeing and fine bleaching.
6 In the daily chemical industry, it is used as a toothpaste additive. It can form a colloid with calcium hydrogen phosphate and play a stabilizing role. It can also be used to synthesize detergents and produce shampoo and other products.
7 Used as a water softener in water treatment.
8 Used as a rust remover in mechanical processing.
9 Used as dispersant and emulsifier in chemical production.
10 It can also be used in oil drilling and other aspects.
Storage and transportation characteristics
Stored in a cool, ventilated warehouse. Store in a sealed and dry place, protected from sun and moisture. Transported as general chemicals.
