Trisodium Phosphate |

|
Sodium phosphate is phosphate, which is an inorganic compound. It is easy to deliquescence and weathering in dry air to form sodium dihydrogen phosphate and sodium bicarbonate. It is almost completely decomposed into disodium hydrogen phosphate and sodium hydroxide in water. Electroplating industry is used to prepare alkaline detergent for surface treatment, degreasing and unpolished parts. In the formula of synthetic detergent, because of its high alkalinity, it can only be used in strong alkaline detergent formula, such as car cleaner, floor cleaner, metal cleaner, etc.
Application area:
l Medical field Indications: polycythemia vera, primary thrombocytosis, chronic granulocytic leukemia, chronic lymphocytic leukemia, and superficial mass identification. It is also used for the application of neurodermatitis, chronic eczema, capillary tumor, keloid, pterygium, corneal neovascularization, plasmacytoma, etc.
l Food industry 1. The product quality improver can improve the complex metal ions, pH value and ionic strength of food, so as to improve the binding force and water holding capacity of food. According to Chinese regulations, it can be used in cheese with a maximum dosage of 5g / kg; in western ham, meat, fish, shrimp and crab, the maximum dosage is 3.0g/kg; in canned food, juice, beverage and dairy products, the maximum dosage is 0.5g/kg. 2. It can be used as analytical reagent and softener, and also used for the purification of sugar.
l Industrial field It can be used as softener and detergent, boiler scale inhibitor, fixing agent in printing and dyeing, mercerizing enhancer of fabric, metal corrosion inhibitor or antirust agent. Enamel industry is used as flux and decolorizing agent. It is used as leather degreasing agent and degumming agent in leather industry. |
