摘　　要：试验研究了不同类型的分散剂、不同加入量以及不同的搅拌速度和搅拌时间对纤维水镁石的分散效果,并且对超声波分散与机械分散效果进行了比较。结果表明:阴离子表面活性剂OT对纤维水镁石具有十分良好的分散效果;分散剂用量为100 kg/t,搅拌转速为1200 r/min,搅拌时间为40 min的条件下分散效果最好。This article studied the effect of types and dosage of dispersants, different stirring speed and time on dispersion performances on fibrous brucite. And dispersion effects on fibrous brucite were compared using ultrasonic dispersion and mechanism dispersion. The results indicated that anion active reagent OT had favourable dispersion effect on fibrous brucite. The best dispersion effect was obtained when the dosage of OT dispersant was 100 kg/t, the whisking speed was 1200 r/min and the whisking time was 40 min.
