三硅酸镁制备

1.泡花碱-硫酸镁法：将泡花碱及硫酸镁经预处理后进行反应，然后经漂洗、压滤、干燥、粉碎，制得三硅酸镁。 2.复分解法将泡花碱及硫酸镁经预处理后进行反应，生成三硅酸镁沉淀，经漂洗、压滤、干燥、粉碎，制得三硅酸镁成品。

3.工业上常用刨花碱与硫酸镁进行复分解反应生产三硅酸镁。先将配制成20～22°Bé的硫酸镁溶液静置沉降后经计量加入反应器。再将静置沉淀后的泡花碱清液（20～22°Bé）和烧碱溶液（18～20°bé）定量配成混合碱液，在搅拌下缓慢加入反应器中。加料完毕后继续搅拌5～10min，促使反应完全。反应后物料的ｐＨ值控制在8～10之间。复分解反应式如下。

反应后的料浆用压滤机压滤，并用水洗涤滤饼，直至硫酸根合格为止。滤饼经烘干、粉碎后，用旋风收集器收集，即得成品。
