中文摘要:

      水浴加热条件下,表面活性剂SDS、SLS和PEG10000的复配体改性工业级Mg(OH)2,得到了中位径(D50)1.55μm、分散性好的改性Mg(OH)2。水浴法改性Mg(OH)2的工艺条件为氢氧化镁浓度1.50 mol/L、表面活性剂用量2.50%、矿化剂氯化镁用量3.50%、水浴温度80℃、水浴时间6.0 h、搅拌速度850 r/min。

英文摘要:

      In the water-bath heating condition,the industrial-grade Mg(OH)2 is modified by combination surfactant of sodium dodecylsulphate(SDS),sodium lauryl sulfate(SLS) and polyethylene glycol 10000(PEG10000).The modified Mg(OH)2 of the median diameter(D50) 1.54μm has a good dispersion.The authors give the optimal process conditions of Mg(OH)2 modified by water-bath heating as fellows: concentration of magnesium hydroxide 1.50mol/L,the percent of surfactant 2.50%,the percent of magnesium chloride(mineralizer) 3.50%...
