本文研究了以硫酸铵法制备硫酸钾极其在膨润土中结晶缓释的最佳工艺条件及缓释效果.其最佳工艺条件为:(NH_4)_2SO_4 ∶ KCl配料比1.1∶ 1、搅拌速度2.0 m/s、搅拌时间80 min、矿浆浓度25 g/100 mL、乙醇浓度20 mL/100 mL.
The optimum of technological conditions of potassium sulfate crystal by method of ammonia sulfate and slow-releasing in bentonite were studied.The whisker of potassium sulfate is grown after adding the surfactant M. The optimum conditions is :the ratio of (NH_4)_2SO_4∶ KCl=1.1∶ 1; stirring rate:2.0 m/s; stirring time:80 min; pulp density:25 g/100 g; concentration of ethanol:20%. We know that the potassium sulfate is whisker by SEM,EDS and so on.
