【摘要】：通过控制单因素实验条件,油酸钠作为改性剂,对重晶石进行疏水调控,探究其改性后的效果与改性剂用量、改性温度、改性时间以及BaSO_4质量分数之间的关系。结果表明:重晶石改性的优化条件是:油酸钠的质量分数为1.0%、改性时间为15 min、改性温度为80℃,BaSO_4的质量分数为30%;获得改性后的重晶石润湿接触角度为128°,使重晶石表面从亲水性转化为疏水性。
[Abstract]:By controlling the single factor experimental conditions, sodium oleate was used as modifier to regulate the hydrophobicity of barite, and the effect of modification, the dosage of modifier and the modification temperature were investigated. The relationship between modification time and BaSO_4 mass fraction. The results show that the optimized conditions for barite modification are: sodium oleate 1.0, modification time 15 min, modification temperature 80 鈩，
