The mixture of 1-hydroxyethane-1,1-diphosphonic acid (HEDP), and polyacrylic acid (PAA) and synthesized hydrolyzed polymaleic anhydride (HPMA) was optimized by using simplex lattice of Design-Expert software through calcium carbonate precipitation method. The optimum mass ratio of HEDP, PAA and synthesized HPMA was obtained at 10/10/80, which showed excellent performance on controlling calcium carbonate deposition. The antiscale efficiency of the optimum mixture was 84% and 95%, respectively, in the calcium carbonate precipitation test and the calcium carbonate scale deposit test. The optimum mixture could disturb the crystal growth of calcium carbonate and then affect the morphology and crystal structure of the calcium carbonate precipitates.
通过Design-Expert软件的单纯形格子法，采用碳酸钙沉淀法对1-羟基乙烷-1,1-二膦酸（HEDP）、聚丙烯酸（PAA）和合成的水解聚马来酸酐（HPMA）的混合物进行了优化。得到HEDP、PAA和合成的HPMA的最佳质量比为10/10/80，其在控制碳酸钙沉积方面表现出优异的性能。在碳酸钙沉淀试验和碳酸钙垢沉积试验中，最佳混合物的阻垢效率分别为84%和95%。最佳混合物能够干扰碳酸钙的晶体生长，进而影响碳酸钙沉淀物的形态和晶体结构。
