摘要: 有机膦酸和某些共聚物是目前使用最广泛的两类冷却水阻垢剂。有机膦酸对许多金属离子,如钙、镁、铁和锌等具有优异的鳌合能力,对这些金属的无机盐垢,特别是碳酸钙垢的阻垢能力很强.

Abstract: Inhibition properties of organophosphonic acids and copolymers on calcium carbonate and phosphate scale were studied.Experimental results indicated that scale inhibition percentages of 1-hydroxyethylidene diphosphonic acid(HEDP) on calcium carbonate did not increase with the increasing concentrations of HEDP;for copolymers AA/AMPS and AA/AMPS/MMA,there existed critical concentrations for inhibiting calcium phosphate scale;AA/HPA(or AA/AMPS) and orthophosphate had synergistic effects for inhibiting calcium carbonate scale within certain concentration ranges.These conclusions may have directive value on the practical use of organophosphonic acids and copolymers.

Key words: organophosphonic acid, copolymer, scale inhibitor, synergistic effect
