采用流化床法对硫酸钾晶体生长速率进行研究 .实验表明 :硫酸钾晶体生长线速率随溶液过饱和度、粒径增大而加快 ,与流速关系不大 .硫酸钾结晶过程在实验研究范围内 ,属于表面反应控制 .添加剂的加入不但影响晶体的生长速率 ,还影响其晶习
The fluidized bed method was used to study the growth rate of potassium sulfate crystals. The experimental results show that the growth rate of potassium sulfate crystals increases linearly with the solution supersaturation and particle size, and has little to do with the flow rate. The crystallization process of potassium sulfate in the experimental range Within the surface reaction control.Additives not only affect the crystal growth rate, but also affect the crystal habit
