摘要:
在撞击流反应器中,以氧化锌和磷酸为原料,乙醇-水溶液为溶剂,十六烷基三甲基溴化胺为分散剂,制备了超细磷酸锌产品。分别考察了反应物浓度、反应温度、反应时间、反应器搅拌转速及分散剂的用量对产品粒径的影响,并采用XRD、SEM和激光粒度分布仪对产物进行表征。结果表明制备磷酸锌的最佳工艺条件为:反应物浓度0.86 mol/L、反应温度70 ℃、反应时间1 h、反应器搅拌转速2 400 r/min、分散剂用量1.0%(相对产品理论产量的质量分数)。在该条件下制备的产品的平均粒径为7.094 μm,粒径集中分布在3~15 μm之间。产品的粒径小且分布均匀,晶体微观形貌呈现出规则的薄片状。

Abstract:
In an impinging stream reactor, ultrafine zinc phosphate particles were prepared using zinc oxide and phosphoric acid as starting materials, ethanol-aqueous solution as a solvent, cetyltrime-thylamine bromide as a dispersant. The effects of reactant concentration, reaction temperature and time, the stirring speed of the reactor, and the amount of dispersant added on the particle size of the product were investigated. The product was characterized by X-ray diffraction,scanning electron microscopy, and laser particle size analysis. Results showed that the average particle size of the product is 7.094 μm and the particle sizes centrally distributed between 3-15 μm under an optimum reaction condition of reactant concentration of 0.86 mol/L,reaction temperature of 70 ℃,reaction time of 1 h,stirring speed of the reactor of 2 400 r/min,dispersant mass fraction of 1.0%(mass fraction relative to the theoretical product yield). The product shows a small particle size and a uniform particle size distribution. The micro-morphology of the crystal is a regular flake shape.
