Energieübertragung zur kontinuierlichen Vulkanistation

Analysis of the Efficiency of continuous Vulcanisation Processes

As shown in lab-scale investigations on continuous vulcanisation processes show, that various forms of vulcanisation energy transfer have very different energy demands and deliver material-specific different vulcanisation results and properties. In order to enhance basic knowledge on influential factors on continuous vulcanisation processes, a research is conducted on material-specific ideal vulcanising strategies using a specially […] more...
