摘要
对某发动机国产化过程中密封剂的优选、黏接工艺的改进进行了介绍。经对比分析国产XM系列聚硫密封剂与进口YT-34密封剂性能,决定采用XM-18、XM-281密封剂,在应用中,根据黏接材料的不同,选择不同的密封剂;为提高黏接良品率,对零件表面处理工艺进行了改进;为满足操作,对密封剂进行预热处理的工艺进行了改进;为缩短固化周期,对固化处理工艺进行了改进。以上工艺方法的实施,满足了产品质量要求与进度要求。
Introduced the optimization of sealants and cementation process improvement of a engine when it was in localization. After compared local XM series of sealants with imported YT-34 sealants, we decided to choose XM-18 and XM -281 sealants. According to the different cementation materials, chose different sealants. For improving＇cementation qualified rate, improved surface treatment of parts process; for meeting operation requirements, improved sealants for preheating process; for cutting down cycle, carried out treatment process improvements for solid processing. The implementation of the above met product quality requirements and progress requirements.
