Product Description

Product Description

 

Chemical name: sodium tripolyphosphate
Chemical formula: Na5P3O10
Appearance: white crystalline solid, powdery
Physical properties:
Soluble in water, the aqueous solution is alkaline.
It has a certain density, such as the density of type II is 2.57g/cm³.
There are different crystal types, such as high temperature type (type I) and low temperature type (type II).
Chemical properties:
It has chelating properties and can form soluble chelates with metal ions.
After hydration reaction, it forms hexahydrate crystals with relatively stable properties. The hydration reaction is an exothermic reaction, and the reaction rate decreases with increasing temperature, increasing raw material concentration, and decreasing pH value. Under normal temperature, normal pressure and non-acidic environment conditions, its aqueous solution is stable, but hydrolysis reaction may occur as the pH of the solution decreases and the temperature increases.
Uses:
In the food industry, it can be used as a moisture retainer, quality improver, pH regulator, metal chelator, etc. For example, in meat processing, it can improve the freshness and adhesion of the finished product and increase the yield rate; in fish, it can enhance the properties of fish paste-crab protein gel and maintain the freshness of meat food; it can also be used to soak or blanch vegetables and fruits to maintain their soft properties.
It can also be used as a detergent additive and soap enhancer to prevent bar soap grease from precipitating and frosting; it has an emulsifying effect on lubricating oils and fats and can adjust the pH value of buffered soap solution; it can be used as a water softener in industrial water; it can be used as a pretanning agent in leather making; it can be used as an anti-oil stain agent in the papermaking industry; it can be used as a dispersant when preparing suspensions in industries such as paint, kaolin, magnesium oxide, and calcium carbonate; it can also be used as a drilling mud dispersant.
Precautions for use: Although it is considered a relatively safe food additive, it is still necessary to pay attention to reasonable use. If the human body ingests too much in a short period of time, it may be harmful. At the same time, it is irritating to the eyes, respiratory system and skin. If you accidentally contact it, you should immediately rinse it with plenty of water and seek medical advice.
Storage conditions: It should be stored in a cool, ventilated and dry warehouse. It should not be stored in the open air. It should be kept away from moisture and should not be mixed with incompatible substances.
