I-Mechanical carbon seal inembali ende. Igraphite yi-isoform ye element carbon. Ngo-1971, iUnited States yafunda imathiriyeli yokutywina eguquguqukayo yegraphite, eyasombulula ukuvuza kwevalve yamandla eathom. Emva kokucubungula okunzulu, i-graphite eguquguqukayo iba yinto ebalaseleyo yokutywina, eyenziwa kwiimpawu ezahlukeneyo ze-carbon mechanical kunye nefuthe lamacandelo okutywinwa. Ezi zitywina ze-carbon mechanical zisetyenziswa kwiikhemikhali, i-petroleum, kumashishini ombane ombane afana nokutywinwa kweqondo lokushisa eliphezulu.
Ngenxa yokuba igraphite eguquguqukayo yenziwa kukwandiswa kwegraphite eyandisiweyo emva kobushushu obuphezulu, inani le-arhente edibeneyo eseleyo kwigraphite eguquguqukayo incinci kakhulu, kodwa ayiphelelanga, ngoko ubukho kunye nokwakheka kwe-arhente yokudibanisa kunempembelelo enkulu kumgangatho. kunye nokusebenza kwemveliso.
