Résumé : |
The pillared derivatives from δ-layered sodium disilicate were investigated by intercalation of bisoctyl dimethyl ammonium chloride and dioctadecyl dimethyl ammonium chloride. The influence of various parameters such as water content, pH of the mixture, and time were examined. The resultant samples were characterized by X-ray powder diffraction, Fourier transform infrared, and thermal gravimetric observation. The experimental results showed that δ-layered sodium disilicate was first transformed to kanemite (NaHSi2O4(OH)2 · 2H2O), and subsequently kanemite was pillared with bisoctyl dimethyl ammonium chloride or dioctadecyl dimethyl ammonium chloride. The tribological properties of typical samples then were investigated by point contact test. The results show that the pillared derivatives have good load-carrying capacity and friction-reducing property. |
