Application
Phosphoric Acid may be used to produce variety of Phosphates, electrolyte treatment liquids or chemical treatment liquids, refractory mortar with phosphoric acid and inorganic Coherent. Phosphoric acid is also used as a catalyst, drying agent and cleaner. In coating industry phosphoric acid is used as a rust-proof coating for metals; As a acidity regulator and nutrition agent for yeast food grade phosphoric acid may be applied to 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.
