摘　　要：采用碳酸钙沉积法对单宁酸及其复配物在冷却水中的阻垢性能进行了研究。结果表明,单宁酸有一定的阻垢能力,但效果不理想;单宁酸与HEDP(羟基亚乙基二膦酸)、ATMP(氨基三亚甲基膦酸)和多聚磷酸钠复配后的阻垢率明显增强;单宁酸与PASP(聚天冬氨酸)、PESA(聚环氧琥珀酸)复配后的阻垢率没有增强。Calcium carbonate precipitation method was used to experimental study to the scale inhibition performance of tannic acid and its combination in cooling water. Results showed that the scale inhibition of tannic acid was not good. Its combinations with HEDP, ATMP and tripolyphosphate sodium have obviously enhance; but its combinations with PASP, PESA not have a bit of enhance.
