采用旋转真空烘干法干燥锡酸钠的研究

摘要

研究了采用旋转真空烘干方法干燥锡酸钠的工艺条件,.实验结果表明,采用旋转真空烘干方法干燥锡酸钠是可行的,且锡酸钠的锡百分含量与物料重量,干燥的温度、时间、转速有关.此外,对比实验结果表明,真空烘干对稳定锡酸钠的浊度有利.%Technological conditions of drying sodium stannate by means of rotary vacuum drying are studied in this paper.The results showed that the process of drying sodium stannate by means of rotary vacuum drying is feasible, and the tin content was related to the effects of time, temperature, rotate speed, material weight.Besides, the rotary vacuum drying method is good for stabilizing turbidity of sodium stannate by experiment of comparison.
