Introduction of the product

Sodium Tripolyphosphate, also known as Pentasodium Tripolyphosphate, Sodium Triphosphate, Pentasodium Phosphate, is a kind of inorganic compound, chemical formula Na5P3O10, is a white crystalline powder, easily soluble in water, the aqueous solution is alkaline, it is an amorphous water-soluble linear polyphosphate. Sodium tripolyphosphate has chelating, suspending, dispersing, gelling, emulsifying, pH buffering, etc. It can be used as the main auxiliaries of synthetic detergents, industrial water softeners, tanning pretanning agent, dyeing auxiliaries, catalysts for organic synthesis, dispersing agents for the pharmaceutical industry and food additives.

Classification of Sodium Tripolyphosphate
According to the structure and shape is divided into white powder anhydrous (Na5P3O10) and right-angle parallel hexagonal crystalline hexahydrate (Na5P3O10-6H2O) anhydrous material has a Ⅰ type and Ⅱ type of points. Industrial sodium tripolyphosphate is actually a mixture of type I and type II. Type Ⅰ dissolves quickly, generates hexahydrate by hydration when the thermal effect is large, in the atmosphere is easy to absorb moisture agglomeration. Type II absorbs moisture slowly and is not easy to agglomerate. Therefore, detergent with sodium tripolyphosphate in the Ⅰ type content should not be too high, generally controlled in 10 ~ 30%.
Sodium tripolyphosphate used as detergent auxiliaries
Sodium tripolyphosphate is a kind of detergent additives with excellent performance, and it is also the largest component in the production process of detergent, its role has four aspects: 1, the chelating effect on heavy metal ions: heavy metal ions in the water during the washing process can be combined with the detergent molecules to form insoluble metal salts, which reduces the ability to wash, or even completely out of action. Therefore, it is necessary to add a chelating agent in the detergent that can make the heavy metal ions contained in the water become harmless substances. Sodium tripolyphosphate has a strong chelating effect on heavy metal ions, which can seal them up and eliminate their unfavorable effects on washing. In addition, it can also capture the dirt contained in a variety of metal components in the washing process to make the dirt dissociation, can be used as soap synergist and prevent bar soap grease precipitation and frosting. 2, the dirt to play the role of degumming, emulsification and dispersion: dirt often contains human secretions (mainly proteins and fatty substances), but also from the outside world of the sand, dust, etc.. Sodium tripolyphosphate on the protein in the dirt has expansion, solubilization effect, thus playing the effect of degumming; on the fat to promote the role of emulsification; on the solid dirt to play a role in dispersion; on the lubricating oils and fats have a strong emulsification effect, can be used to regulate the buffer soap PH value. 3, on the detergent to prevent clumping: powdered synthetic detergent with hygroscopicity, such as stored in a place of high humidity, it is necessary to occur the phenomenon of clumping. Phenomenon. The caking detergent is extremely inconvenient to use. The hexahydrate formed by sodium tripolyphosphate after absorbing water has drying properties. When used in large quantities in detergent formulations, it can prevent caking caused by moisture absorption and maintain the dry granularity of synthetic detergents.4 It has a large alkaline buffering effect, which keeps the pH value of the washing solution at about 9.4, thus facilitating the removal of acidic dirt.

Company information

The company's main import and export products include

(1)Flavors and Fragrances:Fragrance is a substance that can be smelled by the sense of smell or tasted by the sense of taste, and is used as an ingredient in the preparation of flavours. In addition to individual varieties, most fragrances cannot be used alone. Flavour is the raw material that gives cosmetics a certain aroma, it is one of the key raw materials in the manufacturing process.

(2)Polymers：Polymerisation is the process by which the repeating units that make up a polymer are linked together by covalent bonds.Polymers can exist in different states depending on the phase, conformation and arrangement of their molecular chains. The two main states are amorphous and crystalline. Polymers usually exist in a semi-crystalline form in which amorphous and crystalline phases coexist.
