摘要
随着能源危机和环境问题的日益严峻,工业余热回收技术成为节能降碳的重要途径。改性聚四氟乙烯(PTFE)因其优异的化学稳定性和热稳定性,在工业余热回收领域尤其是难回收余热方面展现出巨大潜力。分析了近年来关于改性PTFE研究的相关工作,并评价了PTFE改性方法(表面改性、填充改性、共混改性)、性能提升机制及其在余热回收系统中的实际应用进展。发现通过对PTFE进行改性,可以有效提高耐酸性、耐磨性、不粘性,进而提升余热回收效率。改性PTFE在难回收工业余热回收系统中显示出良好的应用前景,尤其是具有高湿、含尘、腐蚀性等换热介质。
With the growing severity of the energy crisis and environmental issues,industrial waste heat recovery technology has emerged as a crucial approach to conserving energy and reducing carbon emissions.Modified polytetrafluoroethylene(PTFE)demonstrates significant potential in industrial waste heat recovery,particularly in challenging scenarios,due to its exceptional chemical and thermal stability.This paper reviews recent research on modified PTFE,evaluating advancements in modification techniques(including surface modification,filler modification,and blending modification),performance enhancement mechanisms,and practical applications in waste heat recovery systems.The findings reveal that modifications to PTFE can effectively enhance its acid resistance,abrasion resistance,and non-stick properties,thereby improving waste heat recovery efficiency.Modified PTFE exhibits promising application prospects in industrial waste heat recovery systems,particularly for heat transfer media characterized by high humidity,dust,and corrosive conditions.
