Nicol, translated by Ji Yongliang: “Development of Cooling Water Inhibitors with Multifunctional Deposition Control Properties”, “Water Treatment Information Report”, total 74 issues. The novel inhibitor POCA, namely phosphonocarboxylic acid, [PO_3H_2-(CH_2-CHCODH)x-(R)yH][SO_3H] has multifunctional properties and can control the deposition of calcium carbonate, calcium phosphate, iron oxide and sludge. It can also inhibit the corrosion of iron metal and the stabilizing effect on zinc. · POCA has a very high calcium tolerance, calcium concentration 1000mg/L (calculated as CaCO3) does not form calcium complex, so it can play a role in high hard water, performance is the same with sulfonate terpolymer, PBTC, Much better than
