| 摘 要： | 本文以Span60为改性剂,对电气石粉体表面改性的工艺条件进行了探讨.通过对改性电气石的活化指数、接触角、吸油值等性能指标的评价,得出其最佳反应条件为:甲苯作溶剂,span60用量为电气石质量的3%,反应温度60℃,反应时间1.0h,矿浆比(电气石质量与溶剂质量之比)为15:50;并对改性电气石的结构进行了表征.

| Abstract: | The technological conditions for the surface modification of tourmaline powder by using Span60 as modifying agents was discussed in this article.Through the assessment of such performance indexes as activation index,contact angle,oil absorption content and so on,the optimal reactive conditions were obtained as follows:toluene acts as solvent,the dosage of Span60 is 3% of the quality of tourmaline powder,the reaction temperature is 60℃,the reaction time is 1h and the weight ration of tourmaline powder to solvent is 15∶50.Meanwhile,the structure of modified tourmaline powder was also characterized in this article. |
