柔性石墨含碳量与气密性关系的研究

Study on the Relation between Sealed Performance and Carbon Content of Flexible Graphite

采用鳞片石墨LZ5 0 - 89、LZ5 0 - 91、LZ5 0 - 93、LG5 0 - 95和LG5 0 - 99制备了五种含碳量不同的柔性石墨板 ,在自制的泄漏率测试仪上测试其泄漏率 ,研究含碳量与气密性能的关系 ;

Five types of flexible graphite gasket sheet with different carbon content were made from scaly graphite LZ50-89、LZ50-91、LZ50-93、LG50-95、and LG50-99 respectively, and their sealed performance were characterized by using the instrument made by ourselves Meanwhile, the relation between their carbon content and sealed performance was researched In addition, the distribution of impurity as well as its influence on the property of flexible graphite was studied also by means of SEM
