Corrosion tsis kam ntawm cov khoom siv valve - hloov tau graphite

Flexible graphite yog ib hom xoob thiab ntxeem tau wormlike khoom tau los ntawm intercalation, ntxuav, ziab thiab kub kub expansion ntawm ntuj graphite flakes. Ntuj graphite muaj cov khoom zoo xws li kub thiab txias, tiv thaiv corrosion, nws tus kheej lubricating thiab lwm yam. Nws kuj muaj cov yam ntxwv ntawm softness, compression resilience, adsorption, ecological ib puag ncig kev sib koom tes, biocompatibility thiab hluav taws xob tiv thaiv uas ntuj graphite tsis muaj. Graphite muaj kev ruaj ntseg zoo nyob rau hauv chav tsev kub thiab tsis eroded los ntawm tej yam muaj zog acid, alkali thiab organic hnyav.
