Sažetak
The crosslinking of PE-XL 4201 was studied by using experiments and a model of the process. The kinetic parameters were calculated from the heat flux – time curves obtained by differential scanning calorimetry working in a DSC (dynamic) mode. Monsanto rheometer test was used to obtained the vulcanization curves at three temperatures. The numerical model was constructed by taking into account the heat transferred by conduction through the cable, as well as the kinetics of heat generated by cure reaction in the insulation. The shared contributions of the convection and radiation heat transfer through the pressured nitrogen were induced in the heat transfer coefficient. Model was applied to real factory process. Calculated conversion and temperatures shows uniformity through the insulation along radial axis as a main condition for the application of the product. Conversion reaches 99 percent as a result of correct implemented process parameters ( line speed, temperature in the tube, nitrogen pressure) in the model.
