| Summary: | Based on industrial Lithium Bromide (LiBr) aqueous solution with concentration 58% in weight, both stability and sintering property of the solution added some nano-particles and relevant dispersant were studied. The results show that an optimum composition could be obtained as concentration of dispersant in the solution varies in 0.3%~0.6%. When heating temperature is at 160℃, the diameter of sintering particles increase greatly during the beginning 24h, and enhance slowly after 48h as the concentration of dispersant varies in 0.1%~1.0%. While the concentration of dispersant is unchanged, the diameter of sintering particles increase dramatically during the beginning 12h, and keep smooth variation after 48h as heating temperature changes from 50℃ to 160℃. After analyzing the microcosmic structure of sintering particles, it is found that the diameter of sintering particles decrease as the concentration of dispersant varies from 0.1% to 1.0%. It shows that the stronger the dispersant, the smaller the diameter of sintering particles, and the thicker the sintering layer. Therefore, it should be compromised between the stability of LiBr aqueous solution added nano-particles with relevant dispersant and sintering phenomenon, and the dispersants that can work under high temperature is better to be chosen. |
