二期处理对Ceramage瓷聚体抗压强度和直径拉伸强度的影响

摘要

Objective: To explore the mechanical characteristic effects of secondarily treated on Ceramage ceramic optimized polymer material. Method: 20 compress strength specimens and 20 diameter tensile strength specimens were made with Ceramage ceramic optimized polymer material. In each group 10 specimens cured in Solidilite light-curing case, the others were treated secondarily after cured in Solidilite,with the condition of 120 ℃,0.6 Mpa and 7 min. All specimens were tested with Bose ElectroForce 3520 type tensile testing machine. Result: The compressive strengths and diameter tensile strengths had significantly increase after secondarily treatment (P <0.01),with increment of 12.90 % and 10.84 %. Conclusion: Secondarily treatment with high temperature and press can significantly improve the compressive strengths and diameter tensile strengths of Ceramage ceramic optimized polymer material.%目的：探讨二期高温高压处理对Ceramage瓷聚体材料机械性能的影响。方法：用Ceramage瓷聚体材料分别制作20个抗压强度和直径拉伸强度测试试件，所有试件在Solidilite光聚合器中常规聚合，而后随机分为两组，一组为对照组，另一组用国产自控多用途牙用树脂聚合器进行二期热压处理，温度120℃，压力0.6 MPa，时间7 min：用Bose公司ElectroForce3520多功能材料实验机测得抗压强度和直径拉伸强度，对二期热压处理前后的测试值用单因素方差分析进行比较。结果：二期热压处理后Ceramage瓷聚体的抗压强度和直径拉伸强度都有了显著提高，提高幅度分别为12.90％和10.84％(P＜0.01)。结论：二期热压处理可以明显提高Ceramage瓷聚体材料的抗压强度和直径拉伸强度。
