背景：采用适当的方法提高材料的聚合程度，有利于改善其相应的理化性能。 目的：观察二期高温、高压处理对Ceramage瓷聚体单体转化率的影响。 方法：应用傅里叶变换红外色谱仪，分别测试经Solidilite聚合器固化的Ceramage体部材料和经过自控多用途树脂聚合仪在温度120 ℃，压力0.6 MPa，时间7 min条件下二次处理后的材料，在标准基线方法下得到各自的单体转化率并进行比较。 结果与结论：常规处理时Ceramage体部材料的单体转化率为(72.7±2.2)%，经二期热压处理后单体转化率为(75.4±1.5)%，提高幅度为2.7%。提示二期热压处理可以显著提高Ceramage体部材料的单体转化率，从而有可能改善材料的各项性能。

Infrared spectra study of monomer conversion effect of post heated and press on Ceramage ceramic optimized polymer

BACKGROUND:Using appropriate methods to improve the degree of material polymerization will help to improve material physical and chemical properties. OBJECTIVE:To study the influence of post heated and press on the monomer conversion of Ceramage ceramic optimized polymer material. METHODS:Twenty Ceramage ceramic optimized polymer material specimens, with diameter of 4 mm and thickness of 3 mm, were double-side cured in Solidilite light cure case for 90 seconds. Ten random specimens had been post heated in 120 ℃ and pressured 0.6 MPa for 7 minutes by multi-purpose resign aggregator. The samples were crushed with a hydraulic machine. The monomer conversion of Ceramage ceramic optimized polymer material was obtained under different conditions. RESULTS AND CONCLUSION:The monomer conversion of Ceramage ceramic optimized polymer material significantly increased from (72.7±2.2)% to (75.4±1.5)%, with the increasing degree of 2.7%. Post heated and press can significantly increase the monomer conversion of Ceramage ceramic optimized polymer material so as to improve material performance.
