This product is composed of organic polyphosphonic acid, polyfunctional polymers, and additives, belonging to a fully organic alkaline formulation. It has scale inhibition, dispersion, and corrosion inhibition properties, outperforming other fully organic formulations, with a recommended dosage concentration of 30-40 mg/L. It is suitable for industrial circulating water with high hardness and high alkalinity, and does not require acid to adjust the pH value.

This product is a graft copolymer of polyacrylamide, which contains a certain number of polar groups in its molecular chain. It can adsorb solid substances suspended in phosphoric acid and charged particles, bridging between particles or causing them to coagulate into larger flocs that settle down through charge neutralization. After adding a settling agent in the filtration process, the settling speed of acid residue in phosphoric acid can be accelerated, making it easier to filter phosphoric acid; adding a settling agent in the concentrated acid storage tank can reduce the residence time of concentrated acid in the tank, lower the solid content in concentrated acid, and increase the load of the device. This product is mainly used in the flotation, filtration, and settling processes in phosphate fertilizer production.

During the shutdown cleaning process of the phosphoric acid pipeline, a mixed acid of dilute sulfuric acid and dilute fluorosilicic acid is generally used as the cleaning solution to remove scaling in the system. These cleaning solutions, while cleaning the pipeline and equipment such as graphite heat exchangers, can also cause corrosion to the stainless steel material in the pipeline. The phosphoric acid pipeline corrosion inhibitor V730 is compounded from organic phosphonic acid, polycarboxylic acid sulfonate copolymer, copper-iron corrosion inhibitors, and film-forming substances. It can effectively slow down the corrosion of equipment by sulfuric acid and fluorosilicic acid in the cleaning solution, improving the utilization rate of the equipment.
