| Abstract: | Based upon the sealing mechanism of MMC, basic parameters and main behaviors for graphite sealing gaskets has experimentally researched. The results show that density and volume of graphite, compress thickness are important factors, which effects compressibility, recovery, relaxation and sealability of gasket, as well as obtain the relations between these factors and their laws. |
