摘要:
以轻烧镁粉为镁源，氨水为沉淀剂，采用直接沉淀法制备超细片状氢氧化镁.通过粒度测试仪研究了不同反应条件对氢氧化镁平均粒径的影响，最终得到合成氢氧化镁的最佳工艺条件.利用X射线衍射、热失重分析、扫描电子显微镜和红外光谱仪对产物氢氧化镁进行了表征.分析了表面活性剂对制备氢氧化镁的影响.结果表明：实验所得产物为超细氢氧化镁，且晶体比较完善，形貌为六方片状.最佳合成工艺条件为反应温度40 ℃、反应时间1.5 h、氨水的用量和滴加速度分别为170 mL和12 mL/min；添加阴离子表面活性剂十二烷基苯磺酸钠能有效改善氢氧化镁的分散性和形貌.
Abstract:
The superfine and sheet magnesium hydroxide was preparaed by direct precipitation method, using the calcined magnesite as magnesium source and ammonia as agent precipitation. The influence of magnesium hydroxide’s average particle size with the relationship of different reaction conditions by particle size tester was studied.And then the best process conditions of the synthesis of magnesium hydroxide was got.The product was verified for magnesium hydroxide by Xray diffraction,scanning electron microscope,thermogravimetric analysis and infrared spectromete.At last, the best synthesis condition was got.The influence of surfactant to magnesium hydroxide was researched.The results show that the experiment product is superfine and sheet magnesium hydroxide;the best synthetic process conditions are of 40 ℃ reaction temperature, reaction time of h 1.5, ammonia water dosage of 170 mL and adding speed of 12 mL/min; the anionic surfactantSDBS can effectively improve the dispersion and morphology of magnesium hydroxide.
