摘要：

目的利用移位式流变仪(Displacement rheometer),开发适当的测量组织调整材料的操作时间和固化时间的方法。方法使用5种组织调整材料.每个材料在23℃和37℃条件下各测量3次.在23℃下发生最初弹性回复的时间定义为操作时间,在37℃下弹性复原率表现为稳定数据的时间定义为固化时间。结果各个组织调整材料的操作时间和固化时间有显著性差异,显示出不同的固化行为.5种组织调整材料中SR的操作时间最短,为(2.7±0.2)min,VG的操作时间最长,为(15.7±0.5)min.VG的固化时间最长[(25.0±0.8)min],SR的固化时间最短[(7.7±1.9)min]。结论移位式流变仪方法可以用于测量组织调整材料的操作时间和固化时间,并对分析组织调整材料的固化过程有重大意义.

Abstract:

Objective To develop and establish the testing methods appropriate for the determination of the working time and setting time of these materials using the Displacement rheometer.Methods Five commercial tissue conditioners were used. Three tests were carried out for each material both at 23 ℃(working time) and at 37 ℃(setting time). The working time was defined as the time when initial elastic recovery of the material was observed at 23 ℃. The setting time was the time when the elastic recovery reached a final constant value at 37 ℃.Results The significant differences were found among the working time and setting time among the different materials. The setting behavior of each material was different. The SR sample exhibited shortest value of working time with (2.7±0.2)min. And the VG sample exhibited longest value with (15.7±0.5)min. In the setting time, the VG sample exhibited longest value ((25.0±0.8)min), and SR sample exhibited shortest value ((7.7±1.9)min).Conclusion The results suggest that the Displacement Rheometer suits with determination of the working time and setting time of tissue conditioner. The method is useful for the evaluation of the setting behavior of these material.
