| 摘 要： | 在陶瓷的制备过程中,通常需将陶瓷粉末分散于水中形成陶瓷浆后再浇铸成型.研究表明[1],陶瓷浆的分散、稳定及流变性质直接影响到成品的性能.因此,研究分散稳定剂对该浆料性质的影响有着重要意义.本文利用电泳和流变学方法研究了TiO2在表面活性剂的水溶液中浓浆体的分散稳定性及流变性质. |

| Abstract: | The effects of sodium dodecyl sulfate(SDS) and ethoxylated octylphenol(TX100) on the adsorption, stability and rheological properties of aqueous TiO2 suspensions have been studied. It was found that the adsorption isotherm of SDS on TiO2 surface was shown to be the type of "S". With the increasing of SDSconcentration, the ζ potential and stability increase, while the viscosity and yield value decrease at first and then increase. The adsorption amount of nonionic surfactant TX100 is much smaller than that of SDS. No obvious effect was shown on the stability and rheological properties of the TiO2 suspensions. |
