J. Cent. South Univ. Technol. (2008) 15(s1): 163-166 DOI: 10.1007/s11771-008-338-7 Viscosity model of high-viscosity dispersing system WEI Xian-fu(魏先福)1, WANG Na(王 娜)1, HUANG Bei-qing(黄蓓青)1, SUN..., Beijing 100025, China) Abstract: High-viscosity dispersing system is formed by dispersing the solid particles in the high-viscosity continuous medium. It is very easy to form the three-dimensional......
for xylene can be reached when the amount is 1.2%. Key words: nano-TiO2; surface modification; coating; weatherability; dispersing 1 Introduction Nano-TiO2, as a new inorganic material, has many excellent... diffraction and infrared radiation spectrophoto- meter. Various slurry materials and nano-TiO2 samples before and after coating were measured by Raman analyzer at Peking University. The dispersing stability......
