Product Description Number: N*******8 Type: *8% Price: Real-time Price Manufacturer:Nanjing Baihe Chemical Co., Ltd. Details ofinformation Introduction 1. Name: Sodium Hexametaphosphate 2. Molecular formula: (NaPO3)6(Mr≈ **1.*7) 3. Physical Property: Melting point **6 º C (decomposition), the relative density of 2.**4g/cm3 (*0 º C), soluble in water. 4. Chemical properties: Highly hygroscopic. Gradually absorb water placed in the air exposed, it become web results showed viscose. With calcium, magnesium and other metal ions can generate soluble complexes. 5. Specification: Industry-specific *8, food-grade 6. Appearance: White crystal Or colorless transparent glass flake. Details: Usage: Water softener, detergent, can be used in food, medicine, printing and dyeing, paper making industry. • For meat, fish sausage, ham, etc., can increase the water holding capacity, higher node with nature, to prevent lipid oxidation; • For soybean paste, soy sauce to prevent discoloration, increased viscosity, shorten the fermentation period, adjust taste; • For fruit drinks, soft drinks, can increase the juice yield, increased viscosity, inhibit the decomposition of vitamin C; • Used ice cream can increase the swelling capacity, increase capacity, enhance the emulsion to prevent the paste damage, improve the taste and color; • For dairy products, beverages to prevent the gel precipitation; • Add beer to clarify the liquor to prevent the turbidity; • For beans, canned fruits and vegetables can be stable natural pigment, protecting the food color. • In addition, sodium hexametaphosphate aqueous solution sprayed on the cured meat, can improve the corrosion resistance. • Hexametaphosphate also in industrial production as a water softener, such as used in the dyeing and finishing, on the role played soft water. Production process: By the soda ash or caustic soda solution and phosphoric acid and in response, continued after the completion of heating to **0 º C, generate partial sodium, and then heated to **0 º C and the aggregate cost of crystal melting, production after quenching (pressure tablets) was prepared. Food grade sodium hexametaphosphate and be admitted to the reaction after the completion of the removal of arsenic, in addition to heavy metals, purification, re-heating melt obtained by baking. Features: There are industrial grade and food grade two, different uses, different prices.
