| Abstract: | 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%... |
