The surface of hydromagnesite particles were modified by a wet-modification method. The influences of type and dosage of surface modifier, slurry concentration, modification temperature and time on the contact angle and activation index of hydromagnesite particles were investigated. The modified hydromagnesite particles were characterized by contact angle measurement, X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy. The results show that a suitable modifier is sodium stearate and the optimum condition is slurry concentration of 50 g/L, modifier dosage of 4% (in mass fraction) of modified hydromagnesite particles, modification temperature of 75 ℃ and time of 50 min. Under the optimum condition, the contact angle of modified product is 130.9° and the activation index is 99.97%. There is little influence of surface modification on the phase composite, chemical structure, thermal decomposition and morphology of hydromagnesite particles. The essence of the modification of hydromagnesite particles is that the hydrophilic group of sodium stearate is absorbed on the particle surface due to the physical adsorption and the hydrophobic group faces outward. Therefore, the surface of hydromagnesite particles changes from hydrophilic to hydrophobic.

利用湿法工艺改性碱式碳酸镁,研究了改性剂种类及用量、料浆浓度、改性温度和时间对接触角和活化指数的影响。借助接触角测量仪、X射线衍射仪、红外光谱、热重分析和扫描电子显微镜表征改性前后碱式碳酸镁的性能。结果表明:适宜的改性剂为硬脂酸钠,最佳改性工艺为料浆浓度50 g/L,改性剂用量4%(占碱式碳酸镁粉末的质量),改性温度75 ℃,改性时间50 min。在最佳条件下,改性粉体的接触角为130.9°,活化指数为99.97%。表面改性过程对碱式碳酸镁的物相组成、化学结构、热分解和形貌没有明显影响。硬脂酸钠改性碱式碳酸镁的实质主要是硬脂酸钠中亲固基与碱式碳酸镁表面发生物理吸附,其疏水基朝外,从而使得碱式碳酸镁表面由亲水性变为疏水性。

利用湿法工艺改性碱式碳酸镁,研究了改性剂种类及用量、料浆浓度、改性温度和时间对接触角和活化指数的影响。借助接触角测量仪、X射线衍射仪、红外光谱、热重分析和扫描电子显微镜表征改性前后碱式碳酸镁的性能。结果表明:适宜的改性剂为硬脂酸钠,最佳改性工艺为料浆浓度50 g/L,改性剂用量4%(占碱式碳酸镁粉末的质量),改性温度75 ℃,改性时间50 min。在最佳条件下,改性粉体的接触角为130.9°,活化指数为99.97%。表面改性过程对碱式碳酸镁的物相组成、化学结构、热分解和形貌没有明显影响。硬脂酸钠改性碱式碳酸镁的实质主要是硬脂酸钠中亲固基与碱式碳酸镁表面发生物理吸附,其疏水基朝外,从而使得碱式碳酸镁表面由亲水性变为疏水性。

The surface of hydromagnesite particles were modified by a wet-modification method. The influences of type and dosage of surface modifier, slurry concentration, modification temperature and time on the contact angle and activation index of hydromagnesite particles were investigated. The modified hydromagnesite particles were characterized by contact angle measurement, X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy. The results show that a suitable modifier is sodium stearate and the optimum condition is slurry concentration of 50 g/L, modifier dosage of 4% (in mass fraction) of modified hydromagnesite particles, modification temperature of 75 ℃ and time of 50 min. Under the optimum condition, the contact angle of modified product is 130.9° and the activation index is 99.97%. There is little influence of surface modification on the phase composite, chemical structure, thermal decomposition and morphology of hydromagnesite particles. The essence of the modification of hydromagnesite particles is that the hydrophilic group of sodium stearate is absorbed on the particle surface due to the physical adsorption and the hydrophobic group faces outward. Therefore, the surface of hydromagnesite particles changes from hydrophilic to hydrophobic.
