摘要
随着聚对二甲苯(Parylene)镀膜技术的快速发展和应用,如何有效提高聚对二甲苯材料的利用率、提高成膜质量、降低生产成本等在工业化生产过程中被广泛关注。本文对常规聚对二甲苯真空镀膜设备的结构特点和应用现状进行了详细分析,结合稀薄气体流动特性、传热学及工业化生产需求,设计研制了采用内置裂解加热器的聚对二甲苯真空镀膜设备。同时,根据聚对二甲苯镀膜室特有的环境工况以及膜层可抵御酸碱、盐雾、霉菌的特性,提出了对鲜花和低水分干种子进行镀膜保护的工艺研究,拓展了聚对二甲苯镀膜技术在农业领域的应用。
With the rapid development and wide application of parylene coating technology,how to effectively increase the utilization rate of parylene materials,improve the quality of the film,and reduce costs has been widely concerned in the industrial production process.In this paper,depending on the structural characteristics and application status of conventional parylene vacuum coating equipment,a type of parylene vacuum coating equipment with a built-in pyrolyzer is developed,in which flow characteristics of rare gas,heat transfer and industrial production requirements are concerned.At the same time,according to the unique environmental conditions of the parylene coating room and the characteristics of the film to resist acid and alkali,salt spray and mold,coating protection for flowers and low-moisture dry seeds is proposed,which will expand the application of parylene coating technology in the agricultural field.
