橡胶薄膜是飞机、发动机调节控制系统使用的关键性敏感元件。多年来,国产航空橡胶薄膜,特别是以5266和5870丁腈橡胶为基、特种棉布为骨架的薄膜,由于丁腈橡胶本身的耐老化能力差,加上使用的骨架棉布厚度、纺织密度和表面平整度每批次不同以及断头、断线的存在,使薄膜在贮存和使用过程中极易产生鼓泡、离层、渗漏、龟裂和耐压爆破强度低等质量问题,不仅满足不了飞机发动机提高性能和延长寿命的要求,而且在保证贮存使用期内也经常出现问题,成为当前影响飞机、发动机使用和
Rubber film is the aircraft, the engine control system uses the key sensitive components. Over the years, China-made aviation rubber film, especially the 5266 and 5870 nitrile rubber-based, special cotton as the skeleton of the film, due to the aging resistance of nitrile rubber itself is poor, with the use of skeleton cotton thickness, textile density and surface The flatness of different batches and the presence of broken ends and broken wires make the film easy to produce bubbling during storage and use, and the problems of low quality such as separation, leakage, cracking and pressure bursting strength are not only unsatisfied Aircraft engines to improve performance and extend the life of the request, but also to ensure that the storage period is also often a problem that has become the current impact of aircraft, engine use and
