摘要
将含有不同质量分数聚乙烯醇(PVA)的PVA-KH2PO4-Na2HPO4体系缓冲溶液作为骨水泥的调和液,将其与磷酸钙骨水泥粉末混合后成型。将试样在接近生理条件(相对湿度100%,温度(37±1)℃)下养护24h,发现PVA掺入量为1%时的抗压强度达到31.71MPa,比未掺入的提高了将近70%。
PVA of various mass were added into the solution to formulate mixed solution of various mass percent, Compressive strength of the resulted samples which were added 1% PVA was 31.71 MPa after ageing in nearly physiological conditions (100% relativehumidity, (37±1)°C), and it is the best. It could have been improved by 70% compared with the samples without PVA.
