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. |
