Abstract: The polymerized phosphate salt anticorrosive is produced by mixing 60-90 wt.% NaH2PO4, 0-10 wt.% Na2H2PO4, 0-20 wt.% zinc carbonate (ZnCO3), 1-5 wt.% calcium carbonate (CaCO3), 1-5 wt.% aluminium oxide (Al2O3) and 0-5 wt.% silica, drying the mixture, heating it at 800-1000 deg.C and 10 deg.C/min heating rate, and polymerizing it at 850 deg.C for 0.5-1 hr. The anticorrosive has a good anticorrosion effect, and is useful for drinking and industrial water systems.

Abstract: A rustproofing agent containing polymerized phosphate is manufactured by (A) mixing raw materials in a proper ration, (B) drying and high-temperature polymerizing mixed raw materials in a S- type cylindrical polymerization reactor, (C) molding the polymerized mixture in the form of glass beads in a molder of which the temperature is kept at 150-300 deg.D, and (D) cooling the product to a constant temperature. The polymerization reactor, which is equipped with a distributor to uniformly distribute melt product successively downwards, consists of four heating zones of temperatures of 700-800 deg.C, 800-850 deg.C, 800-900 deg.C, and 800-1000 deg.C.
