【摘要】 文章介绍了BD-5水质稳定剂对低硬低碱度地表水的阻垢性能研究情况。由阻垢筛选试验测定了在不同加药剂量情况下的极限浓缩倍率,确定了最佳加药量;进而通过动态模拟试验,利用在一定浓缩倍率下换热管污垢热阻的变化综合考察了所加水处理药剂的阻垢效果。更多还原

【Abstract】 The research status of scale-resistant property of water quality stabilizer BD-5 for low hardness and low alkalinity surface water is presented in this paper. Through scale-resistant selecting tests, the extreme concentrations under different dosages are measured, and lowest dosage identified. Further, through dynamic simulation tests and examining variation of thermal resistance of scale in heat-exchange tubes under different chemical dosage, the scale-resistant property of water treatment chemical dosage is observed. 更多还原
