Industrial and Food Grade Sodium polyphosphate
Sodium hexametaphosphate, molecular formula: (NaPO3)6, white powder crystal, or colorless transparent glass flake or block solid. Soluble in water, insoluble in organic solvents. The aqueous solution is alkaline. Hygroscopicity is very strong, exposed to the air can gradually absorb water and become a viscous material. With calcium, magnesium and other metal ions can generate soluble complexes. Widely used in food and industrial fields. Used as a high-efficiency softener for cooling water treatment in power stations, locomotives, boilers and fertilizer plants, detergent additives, control or anti-corrosion agents, cement hardening accelerators, streptomycin refining agents, fiber industry, bleaching and dyeing industry detergent. The mineral processing industry is used as a flotation agent. It is used as a drilling pipe in medicine to prevent rust and to control the viscosity of slurry during oil drilling. In textile printing, tanning, paper making, color film, soil analysis, radiochemistry, analytical chemistry and other departments also have certain uses.
1. Properties: White powder crystal, or colorless transparent glass flake or block solid.
2. Density (g/mL, 25°C): 2.5.
3. Melting point (decomposition, oC): 616.
4. Solubility: Soluble in water, insoluble in organic solvents. The aqueous solution is weakly acidic. Hygroscopicity is very strong, exposed to the air can gradually absorb water and become a viscous material. With calcium, magnesium and other metal ions can generate soluble complexes.
1. Mainly used for food and industrial industries. Among them, food industry applications are mainly:
Sodium hexametaphosphate is used in meat products, fish sausages, hams, etc. to increase water retention, increase nodulation, and prevent fat oxidation.
For soybean paste, soy sauce can prevent discoloration, increase viscosity, shorten the fermentation period, adjust the taste.
It is used in fruit drinks and refreshing beverages to increase juice yield, increase viscosity and inhibit vitamin C decomposition.
For ice cream can increase the expansion capacity, increase the volume, enhance emulsification to prevent paste damage, improve the taste and color.
For dairy products, beverages to prevent gel precipitation.
Add beer to clarify liquor and prevent turbidity.
For canned beans, canned fruits and vegetables, can stabilize natural pigments, protect food color.
The sodium hexametaphosphate aqueous solution is sprayed on cured meat to improve the antiseptic properties.
2. The industrial industry mainly includes:
Sodium hexametaphosphate can be heated with sodium fluoride to produce sodium monofluorophosphate, which is an important industrial raw material.
Sodium hexametaphosphate as a water softener, if used in dyeing and finishing, play a role in soft water.
Sodium hexametaphosphate is also widely used as a scale inhibitor in water treatment industries such as EDI (resin electrodialysis), RO (reverse osmosis), and NF (nanofiltration).
