Research on the stability of nano TiO_2 in the system of water dispersion

Guo Xiao-jun

Abstract

Studied on the dispersion of rutile nano TiO2 powder in water by different dispersing agents.Discussed the influence of different dispersants dosage,coupling agents dosage,pH value of nano TiO2 dosage on the nano TiO2 dispersion system.The result shows that the optimal dispersant SK-5040 dosage is 1.0 g,KH-570 silane coupling agents dosage is 1.5 mL,the concentration of nano TiO2 is 1.0%,pH dosage is 10 in 100 mL water.
