Sodium Tripolyphosphate 94% CAS No. 7758-29-4

Detergent Chemical: Sodium Tripolyphosphate 94% CAS No. 7758-29-4 Application: 1. Used in meat processing, synthetic detergent formulations, textile dyeing, also used as dispersant, cosolvent, etc.
2. Used as a softener, also used in the confectionery industry, etc.3. It is used as a high-efficiency softener for cooling water treatment in power stations, rolling stock, boilers and fertilizer plants. It has a strong ability to fully form Ca2+, and has 19.5g of calcium per 100g of energy. Moreover, due to the chelation and adsorption dispersion of SHMP, the normal growth process of crystals such as calcium phosphate is destroyed, and the formation of calcium phosphate scale is prevented. The dosage is 0.5 mg/L to prevent the fouling rate from 95% to 100%.

Sodium Tripolyphosphate 94% CAS No. 7758-29-4

Nature

Sodium Tripolyphosphate 94% CAS No. 7758-29-4 is a white powder which is readily soluble in water, the aqueous solution is alkaline, and the pH of the 1% aqueous solution is 9.7. There are two crystal forms, α type (high temperature type) and β type (low temperature type), both of which have the same chemical properties, and can obtain the same aqueous solution and crystalline hydrate, but thermal stability, solubility, hydration heat during dissolution, and hygroscopicity. All are different. It gradually hydrolyzes to orthophosphate in water. It has good coordination ability and can be complexed with metal ions such as calcium, magnesium and iron. It is also an inorganic surfactant.

 

Production

The phosphoric acid is neutralized with a soda ash to a ratio of a certain amount of disodium hydrogen phosphate to sodium dihydrogen phosphate (2:1), and the mixture is dried (to obtain an orthophosphate dry material), and then polymerized at 350 to 450℃. The Sodium Tripolyphosphate 94% CAS No. 7758-29-4 is cooled and pulverized to obtain a finished Sodium Tripolyphosphate 94% CAS No. 7758-29-4.

 

Sodium Tripolyphosphate 94% CAS No. 7758-29-4 for Detergent auxiliaries

Sodium Tripolyphosphate 94% CAS No. 7758-29-4 is an excellent detergent builder and the most used component in detergent production. It has four functions:

1, chelation of heavy metal ions: heavy metal ions in the water during the washing process can be combined with detergent molecules into insoluble metal salts, so that the washing ability is reduced, or even completely lost. Therefore, it is necessary to add a chelating agent which can make a heavy metal ion contained in water into a harmless substance in a detergent. Sodium Tripolyphosphate 94% CAS No. 7758-29-4 has a strong chelation effect on heavy metal ions, which can be blocked to eliminate the adverse effects on washing. In addition, it can capture various metal components contained in the dirt, play a role in dissociating the dirt during the washing process, and can be used as a soap synergist and prevent the precipitation and blooming of the bar soap.

2, the role of dissolving, emulsifying and dispersing the dirt: the dirt often contains human secretions (mainly protein and fat substances), and also contains sand, dust and the like from the outside. Sodium Tripolyphosphate 94% CAS No. 7758-29-4 has the effect of swelling and solubilizing the protein in the soil, thereby acting as a degumming effect; promoting the emulsification effect on the fat; dispersing the solid dirt; having a strong emulsification effect on the lubricating oil and the fat, available Adjust the pH of the buffer soap.

3, the detergent has a role in preventing agglomeration: the powdered synthetic detergent is hygroscopic, such as storage in a place with high humidity, agglomeration will occur. The agglomerated detergent is extremely inconvenient to use. The hexahydrate formed by the absorption of Sodium Tripolyphosphate 94% CAS No. 7758-29-4 has a dry characteristic. When used in a large amount in the detergent formulation, it can prevent agglomeration caused by moisture absorption and keep the dry detergent of the synthetic detergent.

4, has a large alkaline buffering effect, so that the pH of the washing solution is maintained at about 9.4, thereby facilitating the removal of acidic soil.

Chemical properties White powder. Soluble in water, its aqueous solution is alkaline.

 

Application

1. Used in meat processing, synthetic detergent formulations, textile dyeing, also used as dispersant, cosolvent, etc.

2. Used as a softener, also used in the confectionery industry, etc.

3. It is used as a high-efficiency softener for cooling water treatment in power stations, rolling stock, boilers and fertilizer plants. It has a strong ability to fully form Ca2+, and has 19.5g of calcium per 100g of energy. Moreover, due to the chelation and adsorption dispersion of SHMP, the normal growth process of crystals such as calcium phosphate is destroyed, and the formation of calcium phosphate scale is prevented. The dosage is 0.5 mg/L to prevent the fouling rate from 95% to 100%.

4. Tissue improver; emulsifier; buffer; chelating agent; stabilizer. Mainly for the tenderization of ham canned; soft bean can be softened in canned beans. It can also be used as a water softener, a pH adjuster and a thickener.

5. Used for soap synergists and to prevent the precipitation and blooming of bar soap oil. It has a strong emulsification effect on lubricating oil and fat and can be used to adjust the Ph value of the buffer soap. A softener for industrial water. Tanning pre-tanning agent. Dyeing aids. It is used as a dispersing agent in the preparation of suspensions in industries such as paint, kaolin, magnesia, and calcium carbonate. Drilling mud dispersant. The paper industry is used as an anti-oil agent.

6. Sodium Tripolyphosphate 94% CAS No. 7758-29-4 is used as detergent, as auxiliary agent, soap synergist and preventing crystallization and blooming of bar soap, industrial water softener, tanning pre-tanning agent, dyeing auxiliary, oil well excavation control agent, system An effective dispersant for the treatment of paper oil stain inhibitors, paints, kaolin, magnesia, calcium carbonate and the like. Food grade Sodium Tripolyphosphate 94% CAS No. 7758-29-4 can be used as a food improver for various fish products and as a clarifying agent for beverages.

7. The quality improving agent of the work has the functions of improving the complex metal ions of the food, the pH value, and increasing the ionic strength, thereby improving the cohesiveness and water holding capacity of the food. China's regulations can be used for dairy products, fish products, poultry products, ice cream and instant noodles, the maximum use amount is 5.0g/kg; the maximum use amount in canned food, juice (flavor) beverages and vegetable protein beverages is 1.0g/kg.
