We have 75% industrial grade and 85% food grade; The main uses of phosphoric acid are: The main functions of phosphoric acid are as follows
1. Phosphoric acid is the raw material for the production of important phosphate fertilizer (superphosphate, Bai potassium dihydrogen phosphate, etc.) and feed nutrient (calcium dihydrogen phosphate).
2. In order to protect metal from corrosion, insoluble phosphate film is formed on the surface of metal.
3. Mixed with nitric acid as chemical polishing agent to improve the surface finish of metal.4. Production of detergent, pesticide raw material phosphate.5. Raw materials for the production of phosphorus containing flame retardants.6. Phosphoric acid is one of the food additives. As an acid and yeast nutrient in food, coke contains phosphoric acid. Phosphate is also an important food additive and can be used as a nutritional enhancer.7. Phosphoric acid can be used to prepare phosphorus containing drugs, such as sodium glycerophosphate.CAS is 7664-38-2； package is 35kg/drum; 330 kg/drum; 1650kg/IBC
