| application | Industrial use: Mainly used in electroplating, phosphating solution and industrial phosphate production. Food Grade Uses: Food grade phosphoric acid is mainly used in the pharmaceutical, sugar and food industries. Except for direct consumption in the food industry (acidulants and yeast nutrients in the food industry such as cola, beer, candy, salad oil, dairy products, etc.), most of them are used in the production of food-grade phosphates, including sodium, potassium, and calcium salts. , zinc salts, aluminum salts, polyphosphates, phosphoric acid double salts, etc. |
| Package | 20L/200L polyethylene plastic drum, 1000L IBC tank, ISO Tank or bulk. |
