Phosphino-Carboxylic Acid (PCA) is an organic compound with excellent scale inhibition and dispersion properties. It exhibits excellent dispersion of calcium carbonate and calcium phosphate scales by introducing a phosphonic acid group into the carboxyl group, and effectively inhibits the deposition of barium sulfate, strontium sulfate, and silica scales. PCA has wide applicability, good chemical stability,…
