摘要

垫片是用于板式热交换器的密封元件，在使用过程中会受到恶劣条件的影响。特别是，压缩状态，加上温度，会导致性能过早恶化。为了监测和预防这种情况，本研究使用TTS（时间-温度叠加）方法和Arrhenius方法来预测FKM垫片的寿命。为此，在不同温度下进行长达6个月的热氧化老化，监测压缩集（CS）和邵氏硬度。结果表明，在140°C的工作温度下，垫片可以承受长达300天的使用寿命。

Study of Thermo-Oxidative Aging of Fluorinated Gaskets (FKM) Used in Plate Heat Exchangers

Gaskets are sealing elements used in plate heat exchangers, which are subjected to aggressive conditions during service. In particular, the compression state, together alongside temperatures, can cause a premature deterioration of properties. To monitor and prevent such a situation, this study uses the TTS (time-temperature superposition) method and Arrhenius to predict the lifetime of FKM gaskets. For this purpose, thermo-oxidative aging is conducted at different temperatures for up to 6 months, monitoring compression set (CS) and Shore A hardness. The results indicate that the gasket can withstand periods of up to almost 300 days in service for an operating temperature of 140 °C.
