Conclusion: The product is in conformity with BP/USP/FCC/E331.
: BP/USP/FCC/E331 . |
food:
Sodium citrate is mainly used as a food additive, the largest demand, can also be used as flavoring agent, expansion agent, stabilizer, buffer, and emulsifier; In addition, sodium citrate and citric acid together, can also be used as flavor agents, gels and nutritional supplements in a variety of pastries, cold drinks, fruit juices, beverages, cold drinks, dairy products and jams.
medicine:
In 1914, sodium citrate was developed as a long-acting anticoagulant, allowing blood to be preserved longer. In 1915, at The Malta Sinai Hospital in New York, Richard. Levinson demonstrated that the use of sodium citrate as an anticoagulant could one day transform the current transfusion operation, in which donors and donors must be in the same place at the same time, into the blood bank system we use today. Sodium citrate also has preservative properties and is used to preserve some medicines.
Construction industry:
In the construction industry, sodium citrate can be added as a retarder when making concrete, which can improve the freezing resistance, compression resistance and tensile properties of cement products. Under the social conditions of increasingly serious environmental problems, sulfur dioxide in the exhaust gas of some smelters seriously exceeds the standard. Some studies have shown that using sodium citrate's own characteristics to remove sulfide in the industrial tail gas is effective.
Electroplating and Manufacturing:
Sodium citrate has good complexing properties, so it is also used in electroplating industry. With the rapid development of electroplating technology, neutral citric acid nickel plating has the advantages of environmental protection, no pollution and easy maintenance, small corrosion, excellent coating performance, so it has been used in scale in industrial production. In addition, sodium citrate is also used in the manufacturing of nanomaterials and ceramic industry as grinding aid and whitening technology.
Industrial cleaning:
Due to the extensive application of sodium tripolyphosphate in the washing industry, the washing wastewater contains a large amount of phosphate, which makes the water rich in nutrients, and algae breeding rapidly causes red tide, so that the lack of oxygen in the water greatly endangers the survival of water organisms, which has become an urgent problem to be solved in environmental protection. Some countries have limited phosphorus in detergents since the 1970s. Sodium citrate has been widely used in the manufacture of phosphate-free washing powder and liquid detergent because of the properties of sodium citrate added to detergent can improve the decontamination effect. Studies show that sodium citrate special cleaning agent is non-corrosive, so some precision instruments can also use this special cleaning agent to clean. People pay more and more attention to food safety. In order to remove pesticide residues, a special cleaning agent containing sodium citrate has been developed for cleaning vegetables and fruits. With the development of research, sodium citrate has been used more and more.
