| 目的 分析热封设备连续加热热封工艺的能耗模型，优化设计适合大尺度热封设备的间歇加热热封工艺。方法 首先通过电热特性试验了解镍铬合金的升降温规律，拟合得到镍铬合金的升降温模型。其次分析连续加热热封工艺能耗模型，提出适用于大尺度热封设备的间歇加热热封工艺流程，并建立能耗模型。结果 以多层聚对苯二甲酸乙二醇酯/聚乙烯(PET/PE)复合膜为热封对象，以最小能耗为优化目标，计算得到最优的热封工艺流程。结论 大尺度热封设备采用间歇加热热封工艺加工可以有效减少能量损耗。 |

| The work aims to analyze the energy consumption model of continuous heating thermal sealing process of thermal sealing equipment, and optimize intermittent heating thermal sealing process suitable for large-scale thermal sealing equipment. Firstly, the temperature rise and fall rule of nichchromium (Ni-Cr) alloy were studied by electric heating characteristic test, and the temperature rise and fall model of Ni-Cr alloy was obtained by fitting. Secondly, an energy consumption model of continuous heating thermal sealing process was analyzed, and an intermittent heating thermal sealing process suitable for large-scale thermal sealing equipment was proposed and an energy consumption model was established. With multi-layer PET/PE composite membrane as the thermal sealing object, and the optimal thermal sealing process was calculated with the minimum energy consumption as the optimization objective. The results show that the energy loss of large-scale thermal sealing equipment can be reduced effectively with the intermittent heating thermal sealing process. |
