Applications of Industrial Phosphoric Acid
1. Metal Surface Treatment
Industrial phosphoric acid is commonly used for pickling, cleaning, and rust removal of steel and non-ferrous metals. It improves surface adhesion before painting or coating, ensuring durability and corrosion resistance.
2. Water Treatment Chemicals
Phosphoric acid serves as a raw material for phosphate-based water treatment agents, helping to control scale, adjust pH, and prevent corrosion in industrial water systems.
3. Fertilizer Production
As an essential intermediate, industrial phosphoric acid is used to manufacture phosphate fertilizers such as diammonium phosphate (DAP) and monoammonium phosphate (MAP), which are critical for modern agriculture.
4. Chemical Manufacturing
It is widely applied in the production of detergents, phosphate salts, fire retardants, and industrial cleaners. Its strong acidity and chemical reactivity make it a versatile industrial raw material.
5. Equipment Cleaning
In food and beverage industries (technical use only), phosphoric acid can be used to clean processing equipment, removing mineral deposits and scale effectively.
