3. Use
agriculture: Phosphoric acid is an important raw material for the production of phosphate fertilizers (superphosphate, potassium dihydrogen phosphate, etc.) ) raw materials.
Industry: Phosphoric acid is an important chemical raw material, and its main functions are as follows:
1. Treat the metal surface and form an insoluble phosphate film on the metal surface to protect the metal from corrosion.
2. Mixed with nitric acid as a chemical polishing agent to improve the smoothness of the metal surface.
3. Phosphate esters, raw materials for the production of detergents and pesticides.
4. Raw materials for the production of phosphorus-containing flame retardants
Food: Phosphoric acid is one of the food additives. It is used in food as a sour agent and yeast nutrient. Coca-Cola contains phosphoric acid. Phosphate is also an important food additive and can be used as a nutritional enhancer.

Application

Agriculture: Phosphoric acid is an important raw material for the production of phosphate fertilizer (superphosphate, potassium dihydrogen phosphate, etc.), but also for the production of feed nutrients (calcium dihydrogen phosphate).

Industry: Phosphoric acid is an important chemical raw material. Its main functions are as follows:

1. Treat the metal surface and generate an insoluble phosphate film on the metal surface to protect the metal from corrosion.

2. Mixed with nitric acid as a chemical polish, to improve the finish of metal surface.

3. Production of detergent, pesticide raw material phosphate ester.

4. Production of raw materials containing phosphorous flame retardant.

Food: Phosphoric acid is one of the food additives, in food as a sour flavor agent, yeast nutrition agent, Coca-Cola contains phosphoric acid. Phosphates are also important food additives that can be used as nutrients

An enhancer.

hosphoric acid is a medium strong acid, and its crystallization point (freezing point) is 21℃. When the temperature is lower than this, semi-aqueous substance formation (ice) crystals will be precipitated. Crystallization characteristics: high phosphoric acid concentration, high purity, high crystallinity.

Phosphoric acid crystallization is a physical rather than a chemical change. Its chemical properties will not be changed by crystallization, the quality of phosphoric acid will not be affected by crystallization, as long as given temperature melting or heating water dilution, it can still be used normally.

Store in low temperature, dry, well ventilated warehouse, away from fire, heat source. Package sealed and stored separately from alkalis, food and feed.

During transportation, ensure that the package is completely sealed. It is strictly prohibited to transport together with food and feed.
