摘要
用吸附了稀土氢氧化物的SiO2(SiO2·RE(OH)3,RE=La,Nd,Y)与高速真空泵油(烃油)制成ER液,研究了它们在电场中表观粘度的变化,结果表明,分散颗粒含量为80.0g/L时,吸附RE(OH)3后可以提高含SiO2电流变液的电流变性能,RE(OH)3不同或RE(OH)3含量不同时对电流变性能有不同的影响。
The silica adsorbed rare earth hydroxide SiO 2·RE(OH) 3 RE=La,Nd,Y dispersed in a hydrocarbon type oil are prepared and their ER effect under D.C.electric field are studied. A more obvious ER effect is observed in SiO 2·RE(OH) 3 than in SiO 2 for the ER fluid density of 80.0g/L.The properties of the fluids show a significant dependence on La(OH) 3,Nd(OH) 3 and Y(OH) 3 and their contents in fluids.
