天然矿石粉表面的氟烷烃处理对其表面疏水性的影响

Effect of Fluorocarbon Treatment on Surface Hydrophobicity of Natural Ore

表征了几种天然矿石粉粉末压实样品的疏水性,探索了氟碳表面处理剂对碳酸钙表面浸润性和表面能的影响。粉末表面的氟烷烃使材料与水的接触角增大,表面能各分量下降。

Hydrophobicity of compacted powder samples of some natural ores was characterized in this paper. The effect of fluorocarbon treatment on the surface hydrophobicity of calcium carbonate was explained. It was verified by the experiments that the arrangement of the fluorocarbon molecules on the powder surface made the contact angle of water with the material surface increased while the polar and dispersive components of the surface energy lowered.
