Phosphoric acid is one of the most widely used chemicals in the industry. As an additive in carbonated beverages, it is used in the production of fertilizers, soap and non-soap detergents, water purification, animal feed and medicines, livestock and poultry food supplements (DI and calcium phosphate), phosphate detergents, The treatment of wastewater, the production of phosphate fertilizers (the most important application), the combustion of certain surfaces and inhibitors of flammability, and also the cleaning and scaling of metal surfaces. Phosphoric acid forms the addition of water to P4O10. Phosphoric acid is poor and cannot be dangerous in normal conditions and in the short term.

Indications:

Preparation of phosphate fertilizers, electroplating and after-treatment industries for the preparation of livestock and poultry feed, phosphating agents, and the preparation of phosphate salts, etc.
