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.

SurfactantsTags : Layered sodium disilicate Surfactant Interaction Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : This paper investigated the interaction of a-Na2Si2O5 and B-Na2Si2O5 with surfactants sodium dodecylbenzene sulfonate (LAS), sodium lauryl sulfate (K12), alkyl polyglycol ether-9 (AEO-9) and a-olefin hydrocarbon sulfonate (AOS) under condition approximating the detergent spray drying process. The interaction samples were characterized by XRD and TG. The experimental results showed that a-Na2Si2O5 and B-Na2Si2O5 sustained their phases after interacted with surfactants. The relative crystallinity of a-Na2Si2O5 had little change after interacting with surfactants exception of AOS because it had better adsorbable effect on the surface of a-Na2Si2O5 than LAS, K12 and AEO-9. At the same conditions, the amount of H2O and surfactants were both important factors on the relative crystallinity of béta-Na2Si2O5. It also was proved that the temperature had little influence on the relative crystallinity of both alpha-Na2Si2O5 and béta-Na2Si2O5. Compared with Al-d-Na2Si2O5, a-Na2Si2O5 and B-Na2Si2O5 were more stable than Al-d-Na2Si2O5 after interacted with surfactants.
