Study on Experiment & Mechanism of Chemical Dispersion of Chrysotile Fibers

Peng Tongjiang1 Sun Hongjuan1,2 Ma Guohua1 Liu Kun3(1 Institute of Mineral Materials & Application,Southwest University of Science & Technology,Mianyang,Sichuan 621010;2 College of Materials Science and Engineering,Sichuan University,Chengdu 610065;3 Institute of Resource Processing & Biological Engineering,Central South University,Changsha,Hunan 410083)  
The experiment of using sodium dodecyl benzene sulfonate(SDBS) as a dispersant to disperse chrysotile fibres was carried out and the mechanism of dispersion was discussed.The turbidity method and fiuid method were used to test the dispersion degree of chrysotile fi bers and the dispersion degree were infiuenced by percentage of SDBS,dispersing time and rotate speed of dispersing machine.We used the methods of hot-water coacervation and immediate exsiccation to dry the dispersed fiber plasm.The results showed that the surface of chrysotile fibers are positive charge when they are in water,and SDBS has a great effect on the dispersion of fibers.The diameters of dispersed fibers are 50nm±,the zeta potential constantly remains negative value and the negative value increases with the heightening of pH.The dispersive action and the repulsive interaction of C18H29O3S-,as well as hydrophilic characteristic of its polar tips lead to the dispersion of chrysotile fibers.
