标准范围

该试验包括测定橡胶化合物的门尼粘度如何在与使用该化合物的工艺相关的特定温度下随运行时间而变化。记录门尼粘度增加指定单位数的时间。通过该方法确定的预硫化特性提供了一种估算复合橡胶在高温下能保持多长时间并保持可加工性的方法。

The test consists of determining how the Mooney viscosity of the rubber compound changes with running time at a specified temperature relevant to the process for which the compound is to be used. The time at which the Mooney viscosity has increased by a specified number of units is recorded. The pre-vulcanization characteristics determined by this method provide a means of estimating how long compounded rubber can be maintained at high temperatures and remain processable.
