Product Application
Sodium citrate has the above excellent properties, so it has a wide range of uses. Sodium citrate is non-toxic, has pH regulation properties and good stability, so it can be used in the food industry. Sodium citrate is used as food additive, mainly used as seasoning agent, buffer, emulsifier, expansion agent, stabilizer, etc.
Sodium citrate is mainly used as a food additive, the largest demand, but also can be used as a seasoning, expansion agent, stabilizer, buffer, and emulsifier;
In 1914, it was discovered that sodium citrate has a long-term anticoagulant effect, which can make the blood preserved for a long time. In 1915, at Mount Malta-Sinai Hospital in New York, Richard. Levinson demonstrated that the use of sodium citrate as an anticoagulant would one day transform the current practice of transfusion, where donors and donors must be in the same place at the same time, into the blood banking system we use today.
Sodium citrate also has antiseptic properties and is used for long-term storage of some drugs.
Construction industry
In the construction industry, sodium citrate can be added as a retarder in the production of concrete, which can improve the anti-freezing, compressive and tensile properties of cement products.
Because sodium citrate has good complexing properties, it also has good uses in the electroplating industry.
Industrial cleaning
Due to the large number of applications of sodium tripolyphosphate in the washing industry, resulting in a large amount of phosphate in the washing sewage, so that the water is rich in nutrients, the rapid growth of algae caused by red tide, so that the lack of oxygen in the water, greatly endangering the survival of aquatic organisms, which has become an urgent problem for environmental protection.
