The viscosity of the acrylic bone cement used in total joint arthroplasty is an important material property for determination of the proper handling characteristics and interlock with bone. In this article the rheological properties of the three leading bone cements were determined over a three-decade range of shear rates. In addition, four other cements were tested at a single shear rate. The results indicate that all the acrylic bone cements are non-Newtonian, pseudoplastic materials with significant differences between them. It is shown that the viscosity increases at different rates with respect to increases in time. For the majority of cements there is a steady or increasing rate of viscosity change with time.
全关节置换术中使用的丙烯酸骨水泥的粘度是决定其合适操作特性及与骨结合的重要材料属性。本文测定了三种主要骨水泥在三十年剪切速率范围内的流变特性。此外，还在单一剪切速率下测试了另外四种骨水泥。结果表明，所有丙烯酸骨水泥均为非牛顿假塑性材料，彼此间存在显著差异。结果显示，粘度随时间增加以不同速率上升。对于大多数骨水泥而言，粘度随时间呈稳定或上升的变化速率。
