Mechanical carbon seal ine nhoroondo yakareba. Graphite is isoform ye element carbon. Muna 1971, United States yakadzidza yakabudirira flexible graphite sealing material, iyo yakagadzirisa kubuda kweatomu simba valve. Mushure mekugadzirisa kwakadzika, iyo inoshanduka graphite inova yakanakisa yekuisa chisimbiso zvinhu, izvo zvinogadzirwa kuita akasiyana kabhoni mechanical seals nemhedzisiro yekuisa chisimbiso zvikamu. Aya carbon mechanical seals anoshandiswa mumakemikari, petroleum, magetsi emagetsi maindasitiri akadai sepamusoro tembiricha yemvura chisimbiso.
Nemhaka yokuti girafu inoshanduka inoumbwa nekuwedzera kwegirafu yakawedzerwa mushure mekupisa kwepamusoro, chiyero che intercalating agent inosara mu flexible graphite iduku zvikuru, asi kwete zvachose, saka kuvapo uye kuumbwa kweiyo intercalation agent kune simba guru pahutano nekushanda kwechigadzirwa.
