摘要
以七水硫酸镁为原料、氨水为沉淀剂、选择适宜的表面活性剂,以样品XRD图中(001)面与(101)面衍射峰的相对强弱为考察指标,通过单因素实验,分别考察了反应温度、恒温反应时间、陈化时间、表面活性剂用量及氨镁摩尔比等因素对氢氧化镁样品XRD图中(001)面与(101)面衍射峰相对强弱的影响。实验结果表明,制备阻燃氢氧化镁较适宜的工艺条件为:反应温度40℃、恒温反应时间40min、陈化时间120min、表面活性剂A体积用量4ml、氨镁摩尔比6:1。
Using magnesium sulfate as the raw material, ammonia water as precipitate reagent, choosing the fitting surface active reagent, and taking the diffractive peak＇ s relative intensity of （ 001 ） lattice surface and （ 101 ） lattice surface in the sample XRD diagram as exploring index, passing the single factor oonditional experiments, the influences of reaction temperature, oonstant temperature reaction time, sedimentation time, dosage of the surface active reagent and the proportion of ammonia and magnesium sulfate on the diffractive peak＇s relative intensity of（ 001 ） lattice surface and （ 101 ） lattice surface were investigated. Results showed that the better technological conditions as following： reaction temperature 40℃, oonstant temperature reaction time 40 min, sedimentation time 120 min, dosage of the surface active reagent 4ml, the proportion of ammonia and magnesium sulfate 6：1.
