Application:

For food industry, as a acidity regulator and nutrition agent for yeast, Phosphoric acid of food grade could be applied for flavors, canned food and light drinks as well as used in wine brewery as a nutrients source for yeast to prevent the reproduction of useless bacteria. 

For technical grade industry, phosphoric acid could be used to produce variety of phosphates, electrolyte treatment liquids or chemical treatment liquids, refractory mortar with phosphoric acid and inorganic coheretant. It is also used as a catalyst, drying agent and cleaner. In coating industry it is used as a rust-proof coating for metals.
