Titre : Hydrolysis of a, B-layered sodium disilicate in ions binding process Type de document : texte imprimé Auteurs : J.-X. Dong, Auteur ; J.-P. Li, Auteur ; H. Xu, Auteur ; L.-P. Li, Auteur Année de publication : 2008 Article en page(s) : p. 6-12 Note générale : Bibliogr. Langues : Anglais (eng) Tags : A, B-layeres sodium disilicate Hydrolisys Ion binding process Mechanism Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In different type water, the hydrolysis of B-Na2Si2O5 was investigated near washing clothing concentration by XRD, SEM chemical analysis and residual solid yield. B-Na2Si2O5 changed to kanemite in distilled water. In water with Ca2+ or Mg2+, B-Na2Si2O5 transformed to a mixture of kanemite, Ca(OH)2 and amorphous silicate or a mixture of kanemite (NaHSi2O5 ·3H2O), Mg(OH)2 and amorphous silicate. a-Na2Si2O5 changed to an unknown phase in distilled water. In water with Ca2+ or Mg2+, a-Na2Si2O5 transformed to a mixture of unknown phase, Ca(OH)2 and amorphous silicate or a mixture of unknown phase, Mg(OH)2 and amorphous silicate. The experimental data showed that the divalent cation binding process of a, B-Na2Si2O5 belongs to a mixture process with divalent cations exchange with Na+ cation and precipitation in form of insoluble amorphous solid.

Titre : Preparation and characterization of pillared derivatives from d-layered sodium disilicate and their tribological properties in liquid paraffin Type de document : texte imprimé Auteurs : Yilei Fu, Auteur ; Y. Wang, Auteur ; H. Xu, Auteur ; J.-P. Li, Auteur ; J.-X. Dong, Auteur Année de publication : 2011 Article en page(s) : p.67-72 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Disilicate de sodium' Caractérisation 'Réduction des propriétés friction' 'Ammonium diméthyle dioctadécyle' Portance 'Chlorure d'ammonium bisoctyle' Index. décimale : 668.1 Agents tensioactifs : savons, détergents 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.
