Phosphoric Acid has a variety of applications in industry and daily life, including:
Food and Beverage Industry
Phosphoric acid is used as a food acidity regulator to adjust the acidity and taste of beverages, and can also be used to make certain food processing products.
Fertilizer Production
Phosphoric acid is an important fertilizer raw material used in agriculture to promote crop growth and increase yields.
Metal Surface Treatment
Phosphoric acid can be used as a metal surface treatment agent to remove rust or reduce corrosion on metal surfaces.
Cleaners and Etches
Phosphoric acid can be used to clean and etch surfaces such as metal, ceramics and glass. It is often used to clean metal surfaces to facilitate painting.
Water Treatment Agent
Phosphoric acid can be used as a water treatment agent to control the acidity of water and prevent corrosion of pipes and equipment.
Pharmaceutical & Cosmetic
Phosphoric acid is also used in the production of certain pharmaceuticals and cosmetics. Specific applications require detailed consideration based on concentration and purity to ensure safety and compliance.
In the manufacturing of electronic components, phosphoric acid may be used in some of the following ways:
Metal Surface Treatment
Phosphoric acid can be used as a metal surface treatment agent to remove oxides, grease and other impurities from the metal surface to prepare the metal surface for subsequent coating or welding processes.
Etchants
In printed circuit board (PCB) manufacturing, phosphoric acid is used as an etchant to remove the material covering the copper foil that forms the conductors and components on the PCB.
Cleaning Agents
Phosphoric acid may also be used to clean the surfaces of electronic components to remove oxides, grease, and other dirt in preparation for subsequent process steps.
We offer Phosphoric Acid (H3PO4) in 85% and 75% concentrations, suitable for various industrial, food, and agricultural applications.
Our standard packaging for Phosphoric Acid includes secure IBC Drums and TANK containers to ensure safe transportation and storage.
It serves as an acidity regulator to adjust the taste and pH levels in beverages and is also widely utilized in specific food processing formulas.
In electronics, it is primarily used as an etchant to remove copper foil materials on PCBs, and as a cleaning agent to eliminate surface oxides, grease, and dirt.
Handling Phosphoric Acid requires strict compliance with safety protocols, including wearing proper protective gear, ensuring proper ventilation, and managing liquid waste disposal under professional guidance.
