ELECTRICALLY VISCOUS FLUID |
摘要 |
PURPOSE:To provide an electrically viscous fluid increasing its viscosity by the application of electric voltage. CONSTITUTION:In an electrically viscous fluid obtained by dispersing dielectric substance fine particles in an oily medium having an excellent electrically insulating property, the electrically viscous fluid is characterized in that the oily medium is carbonaceous fine powder having a carbon atom/hydrogen atom (C/H) ratio of 1.70-3.50 and an average particle size of 0.01-100mum and in that the oily fluid is an electrically insulating oil having a dielectric constant of 3 or more and a volume resistivity of 10<9> or more OMEGA.cm. |
