门尼粘度实验

检测项目

门尼粘度值测定：测定橡胶试样在特定温度和转子转速下，达到稳定状态时的扭矩值，该值是表征材料粘度的基础参数。

焦烧时间测定：记录胶料从开始加热到粘度下降至最低点后再上升一定单位值所需的时间，用于评估胶料的加工安全性。

硫化特性曲线分析：通过记录整个测试过程中的粘度-时间曲线，分析胶料的硫化起始、速率及平坦期等特征。

最小扭矩值测定：测量胶料在测试初期粘度达到最小值时的扭矩，反映胶料在未硫化状态下的流动性能。

最大扭矩值测定：测量胶料在测试后期粘度达到最大值时的扭矩，与硫化胶的交联密度和模量相关。

硫化指数计算：根据硫化曲线计算特定时间点的转矩差值，用于量化硫化速率和比较不同配方的硫化行为。

应力松弛行为评估：在测试结束后或特定点停止转子转动，观察扭矩衰减曲线，以评估材料的粘弹性。

返原特性分析：对于某些橡胶，观察其在长时间硫化后扭矩是否下降，以判断硫化返原现象的发生。
