采用离心喷雾干燥工艺制备粉末状聚羧酸系高效减水剂。最佳喷雾干燥工艺：离心雾化器转速16000 r/min，料液温度30°C，干燥室进出口风温200°C/80°C。实现了高浓度聚羧酸系高效减水剂的粉体化。它解决了传统制备粉状聚羧酸减水剂时存在的粘性大、性能低的问题。采用红外光谱法对聚羧酸减水剂喷雾干燥前后的结构进行了分析，并通过宏观性能试验对结论进行了验证。
This paper uses centrifugal spray drying process to prepare powder polycarboxylate superplasticizer. The best spray drying process: speed of centrifugal atomizer is 16000r/min, feed liquid temperature is 30°C, import / export air temperature of drying chamber is 200°C/80°C. It achieves a high concentration of polycarboxylate superplasticizer to prepare powder product. It solves the problem of sticky and low-performance of powder polycarboxylate superplasticizer during traditional preparation. Analyzing the structure of polycarboxylate superplasticizer before and after spray-drying by infrared spectroscopy, and verifying the conclusion through macroeconomic performance experiments.
