Abstract

The present study was an investigation of the effect of the method of mixing the constituents of CMW3 bone cement on selected physical and mechanical properties of the fully polymerized cement. Five such methods were used: hand mixing; "active" vacuum mixing; mixing in a machine that allowed simultaneous mechanical mixing and centrifugation; mixing using this machine followed by application of a "passive" vacuum; and application of a passive vacuum followed by mixing in the machine. It was found that the best overall results were obtained from cement that had been mixed using the second and fifth methods and the values of the properties were: density, 1220 to 1246 kg/m3; areal porosity, 0.02 to 7.04%; ultimate compressive strength, 84 to 112 MPa; ultimate compressive strain, 5.1 to 6.4%; and compressive modulus of elasticity, 2249 to 2877 MPa.

摘要

本研究旨在探讨CMW3骨水泥成分混合方法对完全聚合水泥选定物理和力学性能的影响。使用了五种这样的方法：手工搅拌；“主动”真空搅拌；在允许同时进行机械搅拌和离心的机器中搅拌；使用该机器搅拌后施加“被动”真空；以及施加被动真空后在机器中搅拌。结果发现，使用第二种和第五种方法混合的水泥获得了最佳的总体结果，其性能值为：密度，1220至1246千克/立方米；面积孔隙率，0.02至7.04%；极限抗压强度，84至112兆帕；极限压缩应变，5.1至6.4%；以及压缩弹性模量，2249至2877兆帕。
