Chemical formula: Na5P3O10

Property: White particle or powder, appearant density 0.35-0.90g/cm3, melting point 622ºC. Easily soluble in water, aqueous
solution is alkali. Hydrolyze to orthophosphate in water, complexing with calcium, magnesium, iron and other metal ions and
generate soluble complex. As inorganic surfactant, it has certain properties of organic surfactants.

Packing instruction: Paper bag or PP-PE bag, Net weight 25kg, 50kg 1000kg per bag, or based on the customers' requirements.

Executive standard: GB/T 9983-2004
 

1. Apparent density 0.35-0.9g/cm3, melting point 622ºC, can be soluble in water.

2. Alkaline aquesous solution, 1% aqueous solution of PH 9.7.

3. Can gradually be hydrolysed in the water into subphosphate, has a good ability to compelex metal ions.

4. Can form soluble complexes with calcium, magnesium, iron and other metal ions.

5. Can soften hard water, As an inorganic surface active, but also organin surface active agent.

ndustrial Grade Sodium Hexametaphosphate(SHMP)application:.

 

1. Sodium tripolyphosphate is used for meat processing, synthetic detergent formulations, textile dyeing, also used as dispersing agent, solvent etc.
2. It is used as soft water, also used in confectionery industry.
3. It is used as power stations, locomotive vehicle, boiler and a fertilizer plant cooling water treatment, water softener. It has strong ability to Ca2+ collaterals, per 100g to complex 19.5g calcium , and because SHMP chelation and adsorption dispersion destroyed the normal process of calcium phosphate crystal growth, it prevents the formation of calcium phosphate scale. Dosage is 0.5 mg/L, prevent that scaling rate is up to 95%~100%.
4. Modifier; emulsifier; buffer; chelating agent; stabilizer. Mainly for canned ham tenderization; canned broad beans in the Yuba softening. Can also be used as soft water, pH regulator and thickening agent.
5. It is used for synergist for soap and preventing bar soap grease precipitation and bloom. It has strong emulsification of
lubricating oil and fat. It can be used for adjusting the value of pH of buffer liquid soap. Industrial water softener. Pre
tanning agent. Dyeing auxiliaries. Paint, kaolin, magnesium oxide, calcium carbonate, such as industrial in the preparation of suspensions of dispersant. Drilling mud dispersant. In paper industry used as anti oil agents.
6. Sodium tripolyphosphate is used for detergents. As additives, synergist for soap and preventing bar soap crystallization and bloom, industrial water soft water, pre tanning agent, dyeing auxiliaries, well digging mud control agent, paper with oil on preventing agent, paint, kaolin, magnesium oxide, calcium carbonate, such as hanging floating fluid treatment effective
dispersant. Food grade sodium tripolyphosphate as a variety of meat products, food improver, the clarification of the beverage additives.
7. Quality improver to improve food complexed metal ions, pH value, increasing ionic strength, thereby improving food focus and water holding capacity. Provision of China can be used for dairy products, fish products, poultry products, ice cream and instant noodles, maximum dose is 5.0g/kg; in canned, maximum use juice (taste) beverages and vegetable protein beverage is 1.0g/kg.
 

Application in Detergent.

 

For the ability of complex with Fe,SHMP is the strongest.TSPP could react with Ca2+,Mg2+ to form water soluble complex.,but with Ca,TSPP is the strongest;STPP is the middle.

TSPP could react with water insoluble dust as flocuulation when wash clothes and also emulsify insoluble oils;

TSPP could cause lower surface tension and interfacial tension to mius the usage of surface active materials.
