采用单轴压缩试验机对喷雾干燥法（SD）和干燥中和法（DN）生产的两种碳酸钠粉体的压实性能进行了研究。还与宝莹洗衣粉进行了比较。干燥中和的碳酸钠在压缩到100千帕时表现出更大的抗压性，也产生了更弱的压实。喷雾干燥的碳酸钠没有细小颗粒，但容易压实。差示扫描量热法（DSC）表明，两种粉末在性质上都以无定形为主。吸湿测量表明，两种粉末在50%相对湿度（RH）下表现出相似的方式。然而，干燥中和的碳酸钠在此RH以上具有较高的水分亲和力。颗粒结构也使用扫描电子显微镜检查，显示喷雾干燥颗粒的非均匀内部。
Two types of sodium carbonate powder produced by spray drying (SD) and dry neutralization (DN) were studied for their compaction properties using a uniaxial compression tester. A comparison was also made with Persil washing powder. Dry neutralized sodium carbonate showed greater resistance to compression and also produced a weaker compact when compressed to 100 kPa. Spray-dried sodium carbonate had an absence of fine particles but compacted easily. Differential scanning calorimetry (DSC) showed that both types of powder were predominantly amorphous in nature. Moisture sorption measurements showed that both powders behaved in a similar way below 50% relative humidity (RH). However, dry neutralized sodium carbonate had a high moisture affinity above this RH. Particle structures were also examined using scanning electron microscopy, showing the heterogeneous interior of the spray-dried particles.
